=General
*Added ranges of styles/dyes for Doram's.
-This is a range seprate from the regular ones since Doram's officially have a
-different set number of hair styles and cloth dyes. As of 2018-06-05 they have
-6 hair styles, 8 hair dyes, and no cloth dyes (tho kRO says their will be a few
-added soon).
*min_doram_hair_style
*max_doram_hair_style
*min_doram_hair_color
*max_doram_hair_color
*min_doram_cloth_color
*max_doram_cloth_color
+Added these configs to the client config file.
-These are a seprate set of style/dye ranges for Doram characters.
-This is needed since they have different maxes from humans.
*Updated a few commands to pickup on the style/dye ranges for Doram characters.
*Updated default setting for "max_hair_style" to 29.
*Corrected default setting for "max_hair_color" to 8.
*clif_spiritball_single
*clif_soulball_single
+Changed the packet these functions use to 0x1d0 (ZC_SPIRITS).
-This change fixes a issue where Rebellion's Coin sphere's and Soul Reaper's
-Soul Energy sphere's would look like regular spirit sphere's when the player
-warps to another map, refreshes, and also appear as spirit sphere's to other
-players who walk into view range of the one with the spheres.
-It also fixes a issue where the sphere's may not vanish properly from view
-when the player dies.
*Added job restriction system.
+This allows setting restrictions to different jobs that prevent's them from
-entering certain maps. Attempts of entering a map as a banned job will just
-result in no warpping. Basicly, something as simple as walking into a regular
-map warp won't do anything if the player's job is banned from entering the map.
-This works for teleporting, warping, any warp commands, walking into NPC warp,
-put something else here and it will likely fail as well.
-Should a player playing a job banned from that map somehow login on that map,
-the player will be warped out into Prontera's graveyard behind the church.
-These restrictions can be set in the "job_notallowed" database file.
*Added a missing timer function list entry for the soul energy system.
 
=Database
*Updated const file to support detection of new style/dye ranges for Doram
-characters in NPC scripts.
*Added the "job_notallowed" file.
-This file is used to set jobs that are banned from entering certain maps.
-It basicly works just like item_noequip and skill_nocast_db.
*Rebuilt the map cache.
-This is due to prontera being reverted back to the original version.
 
=NPC
*Updated the 3CeAM super stylist to detect the ranges of styles/dyes for Doram
-character's.
 
=Skills
*RL_MASS_SPIRAL
+Fixed a issue where the skill would deal extremely high damage on targets with
-negeative DEF.

=Update Notes
*Added support for Star Emperor and Soul Reaper jobs.

Hi all,
For the longest time I've been creating custom script commands simply so I can read a value from struct map_session_data{}. For example, I wanted to return the value of sd->state.showzeny, so I created a simple buildin just for that purpose.It would go something like this:
 
BUILDIN(read_showzeny) {     struct map_session_data *sd =  script->rid2sd(st);     if (sd != NULL)         script_pushint(st, sd->state.showzeny);     else         script_pushint(st, -1);     return true; } Seems not bad, right? But then it got me thinking. I'm creating all these script commands for one simple action. Surely there's a better way? That's when I stumbled across the getunitdata() command.
Then it came to me - create a script command which can fetch this data for a player.
The Goal
Create a script command which can fetch the data which map_session_data provides. It would work similar to getunitdata():
*getplayerdata(<account id>, <DataType>{,<Variable>})
Maybe also setplayerdata()?
Helped needed: The one thing is, not all the stuff in there is useful. Maybe it would be best to selectively choose what can be retrieved as data? I made a list for this stuff. Let me know what you think.
 

yes, just patch it
no problem
 

HERE

function GetQuestion { return getd(".question_" + (getarg(0) % 128) + "$[" + (getarg(0) / 128) + "]"); } function GetAnswer { return getd(".answer_" + (getarg(0) % 128) + "$[" + (getarg(0) / 128) + "]"); } function GetHint { return getd(".hint_" + (getarg(0) % 128) + "$[" + (getarg(0) / 128) + "]"); } I believe you made it opposite ?
assuming that you are still using eathena, when script engine was still 128 elements
it should be
return getd(".question_" + (getarg(0) / 128) + "$[" + (getarg(0) % 128) + "]"); although there is no need to do like this anymore because our script engine no longer has such limitation
2nd thing is ...
L_loop: do set .@i, rand( .numQuestions ); // Randomly picks a fact. while( .Q_session & 1 << .@i && .Q_session && .count < .numQuestions ); set .Q_session, .Q_session | 1 << .@i;// max 32 questions rather than using a loop, can use shuffle algorithm
 
EDIT: for below
 

Hi All,
May I request for a Hourly Point NPC with a Target Hours before you get the reward?
There is a menu with Start, Stop and Pause button for logging out/offline purpose.
I already tried my best to edit a hourlypoint script but I failed.
Thanks in advance!
---Solved. Already found it. Sorry for not patiently testing all the topics that I saw.

Hi All,
Can you help me edit this script? Need to change the settings. You must not get the reward once you talked. You must only get the reward if you only reached the target time.
In the photo attached, I talked to NPC in the first time and the NPC already gave the reward. I want if possible, you will only get the reward when you stayed online for 5 hours straight without logging out/disconnect/offline.
Also a menu with Start, Stop and Pause for a player if he will logout of the game.
Thank you.

Hello everyone, I present to you a modified tip box which has been completely translated to English. 
Tested on: 2018-04-04c RagexeRE and worked like a charm.
In your System folder in Client side, replace your tipbox.lub with my translated tipbox i have attached below:
tipbox.lub
Then, Patch your client with whatever settings you want and then open the patched client in hexeditor ( I used XV132 for this)
IMPORTANT NOTE : Make sure you hex a "patched" client. DO NOT do it on an unpatched client or else NEMO will show errors for random "recommended patches" that you select while patching it.
Find the following and replace with hex for english translation : for checkbox: BD C3 C0 DB C7 D2 20 B6 A7 20 BF AD B1 E2 English translation: 53 61 76 65 20 54 69 70 3F 20 20 20 20 20 for close button : B4 DD B1 E2 English translation : 44 6F 6E 65 (korean translation of close has only 4 strings so I had to replace it with "Done" to match the string size -_-) OR go to your NEMO folder/patches/TranslateClient.txt and add this at the end of it then patch your clients: (Thanks to @Asheraf for telling me about this xD)
M: Translate Tip box ------------------------------ F: BD C3 C0 DB C7 D2 20 B6 A7 20 BF AD B1 E2 R: 'Save Tip?' F: B4 DD B1 E2 R: 'Done' if you did everything as said, this will be your result :
Old tip box:

New translated tipbox:
 

 
-- On a funny Note, I had no clue what the korean translation for the Check box was LOL so I just randomly translated it to "Save tip?" instead cuz it was a logical solution LMAO 

Thank you, guys!

As of Release v2018.03.13, the method to generate mapcache for Hercules has changed. A lot of people. myself included, were confused as to how it works. In this thread, I will do my best to explain the new way to generate your cache. This guide is intended to help people using the old system, not to aid new people (i.e. never generated mapcache before), so if you are new, some of it may seem like alien talk.
Old (your source predates [is older than] Feb 18, 2018)
In the old system, there were two ways to generate mapcache
You could run the mapcache executable in Hercules root folder. Or use a program such as WeeMapCache to edit in your required mapcache. These two methods would generate or alter your required mapcache located in db/[pre-re or re]/map_cache.dat. However, they are no longer supported.
New (your source is using Release v2018.03.13 or newer)
The new system involves the use of the new 'mapcache' plugin to generate files. Some quick points:
db/[pre-re or re]/map_cache.dat has been dropped (no longer supported). In its place are individual .mcache files for every map located in maps/[pre-re or re]/ Mapcache executable has been removed. Replaced with the mapcache plugin (src/plugins/mapcache.c). How to generate the mapcache?
Same as before, check conf/map/maps.conf and db/map_index.txt have all the maps you want to cache. Your maps need to exist somewhere in your repository! There are two ways for the plugin to find them:
a. Place all your maps, including resnametable.txt, inside the data folder of your Hercules repo. I.e. Hercules/data/prontera.gat/gnd/gnd/rsw (note: I forget if all three files are needed).
b. OR Configure your conf/grf-files.txt to tell it where to find your GRF(s) which contains your maps. Build the mapcache plugin. On linux, this can be done by running the following command:
make plugin.mapcache
If using MSVC, compile as you would any other plugin. Execute plugin. This can be done using the following command:
./map-server --load-plugin mapcache [param]
In windows, just remove the './' and run the commands in your command prompt. The params:
The first thing you should do is run
./map-server --load-plugin mapcache --help
A list of usable parameters will appear. Here are the ones you need to know for mapcache:
[Info]:   --convert-old-mapcache         Converts an old db/pre-re/map_cache.dat file to the new format. [Mapcache] [Info]:   --rebuild-mapcache             Rebuilds the entire mapcache folder (maps/pre-re/), using db/map_index.txt as index. [Mapcache] [Info]:   --map <name>                   Rebuilds an individual map's cache into maps/pre-re/ (usage: --map <map_name_without_extension>). [Mapcache] [Info]:   --fix-md5                      Updates the checksum for the files in maps/pre-re/, using db/map_index.txt as index (see PR #1981). [Mapcache] ./map-server --load-plugin mapcache --convert-old-mapcache
Rebuild all the .mcache files using your old db/[pre-re or re]map_cache.dat file.
NOTE: You should only run this command when you have an old map_cache.dat file you need to convert.
./map-server --load-plugin mapcache --rebuild-mapcache
Rebuild all the .mcache files using your map files specified in step 2 of generation.
NOTE: You should only run this command in special circumstances. This erases ALL the existing mapcache and rebuilds it with whatever files you provide it. If you don't have the required files, the build will fail and you will be left with missing mapcache files, meaning you won't be able to access those particular maps.
./map-server --load-plugin mapcache --map <name>
Rebuild the .mcache file for the map name you specify. E.g. if you replace <name> with prontera, the maps/[pre-re or re]/prontera.mcache file will be rebuilt.
NOTE: This is the best command to run, as it only caches a single map at a time.
./map-server --load-plugin mapcache --fix-md5
I don't know what checksum is for.
The End
Feel free to ask for help here. I'll try to answer questions re: mapcache if possible. And if you think anything needs correcting or added, let me know.
Hope this helps!

=General
*This is the revisiting of the Kagerou/Oboro skills to bug fix and update the skills for them.
*Cleaned up and optomized some code.
 
=Skills
*Kagerou/Oboro

*KO_MUCHANAGE (Over Throw)
+Recoded the skill.
+Damage is no longer reduced in GvG/BG areas.
+Damage is no longer reduced by half on enemy players.
+Success chance of hitting is now seprate for each enemy target.
+Damage is now divided between enemys detected in AoE.
-This means its divided based on the number of enemy's detected in the AoE
-and not by the number of enemys hit.
*KO_HUUMARANKA (Launch Huuma Shuriken)
+Damage no longer split between targets.
*KO_MAKIBISHI (Makibishi)

*KO_ZENKAI (Spread Seals)
+Can no longer be stacked on top of each other.
+Random status chance is now applied every second.
+Random status success chance is now 100%, but is reduceable by stats and equips.
+Durations of the random status's is now set to their original defaults.
+Friendly player's standing in the AoE will now get a WATK increase if the weapon
-element is the same as the AoE's element.

1. When to use escape_sql script command
 
.
input .@haha$; dispbottom .@haha$; dispbottom escape_sql(.@haha$); it doesn't has much differences, because it only affect 3 special characters
' <- single quotation mark
" <- double quotation mark
\ <- left slash
if I input -> haha"lala'hehe <-
it will return -> haha\"lala\'hehe <-
this is what we call, Escape a character
in hercules script, we also know we can use " symbol in any string input
mes "Susan says :\" Today I ate 3 eggs \"."; where in the game client, you can see the " symbol in the npc msg box
let's say I have a sql script like this
prontera,153,171,5 script Show Characters 1_F_MARIA,{ mes "input name, I'll show you all characters name it has on that player's account"; input .@name$; .@nb = query_sql("SELECT `char_id`, `name` FROM `char` WHERE `name` LIKE '"+ .@name$ +"'", .@cid, .@name$); if ( !.@nb ) { mes "no result"; close; } for ( .@i = 0; .@i < .@nb; ++.@i ) mes .@cid[.@i] +" "+ .@name$[.@i]; close; } this script has a possibility to be hacked
because to perform sql injection, I can enclose the string with quotation mark, then use another sql command to hack
BUT with an escape_sql command, if the user want to enclose the string with quotation mark to hack the script
the escape_sql command escaped the string, the quotation mark the user input will be escaped
thus the script will become impossible to hack
just now that script was for string input
prontera,153,171,5 script Show Characters 1_F_MARIA,{ mes "input account ID, I'll show you all characters name it has on that player's account"; input .@aid$; .@nb = query_sql("SELECT `char_id`, `name` FROM `char` WHERE `account_id` = "+ escape_sql(.@aid$), .@cid, .@name$); if ( !.@nb ) { mes "no result"; close; } for ( .@i = 0; .@i < .@nb; ++.@i ) mes .@cid[.@i] +" "+ .@name$[.@i]; close; } this is another stupid case.
1. the scripter use string input while the script just needed a number
2. even with escape_sql command over there, there is no quotation mark at all
yes this script also has a risk to be hack
because escape_sql only escape quotation mark.
that hacker don't even have to input quotation mark because it is a number
and an injection query can be sent without any quotation mark input
there are 2 ways to solve this
either use numeric variable for the input command
or enclose that ....
..... WHERE `account_id` = '"+ escape_sql(.@aid$) +"'", .... with single quotation mark, when the hacker input a quotation mark will be escaped by escape_sql command
Reference : https://www.w3schools.com/sql/sql_injection.asp
escape_sql command for another thing is
if the player register their names containing ' or ", these characters are escaped
only happens when the server have no restriction on the creation of players name
hercules\conf\char\char-server.conf
// Manage possible letters/symbol in the name of charater. Control character (0x00-0x1f) are never accepted. Possible values are: // NOTE: Applies to character, party and guild names. // 0: no restriction (default) // 1: only letters/symbols in 'name_letters' option. // 2: Letters/symbols in 'name_letters' option are forbidden. All others are possibles. name_option: 1  
and this was what happened to my SQL dota pvpladder script
Silo's Babies <-- this is a guild name
you can see the 5th string has a single quotation mark
with escape_sql command, that string will turn into
Silo\'s Babies <-- the quotation mark is escaped when send to sql query

2. How to build a case-sensitive table
this is the answer I found
http://dba.stackexchange.com/questions/15250/how-to-do-a-case-sensitive-search-in-where-clause
by default, the table creation use charset = latin1;
means it couldn't do a case-sensitive search
if you want to do a case-sensitive in a query, use BINARY
SELECT * FROM `char` WHERE `name` = BINARY('AnnieRuru'); however using BINARY might have performance hit if it is a big table
so its more recommend to convert your SQL table to collate with latin1_general_cs

let's say this is a sample table
CREATE TABLE `test` ( `id` INT(11) PRIMARY KEY AUTO_INCREMENT, `name` VARCHAR(23) )ENGINE = InnoDB; do an ALTER table syntax
ALTER TABLE `test` MODIFY COLUMN `name` VARCHAR(23) COLLATE latin1_general_cs; or just put it into the table creation
CREATE TABLE `test` ( `id` INT(11) PRIMARY KEY AUTO_INCREMENT, `name` VARCHAR(23) )ENGINE = InnoDB DEFAULT CHARSET = latin1 COLLATE latin1_general_cs;  

3. Choose a table type, MyISAM or InnoDB ?
https://stackoverflow.com/questions/20148/myisam-versus-innodb
Before MySQL 5.5,
MyISAM is mostly use for read-heavy + table locking storage engine = such as pvp ladder ( always select ... order by kill desc )
InnoDB is mostly use for write-heavy + row locking storage engine = such as quest script ( select ... from char_id ... only 1 row is retrieve )
After MySQL 5.6, (currently is 8.0)
just stick to InnoDB
there is only 1 reason MyISAM is better than InnoDB
- MyISAM use smaller disk usage than InnoDB
let's take a look at our MyISAM to InnoDB converter
https://github.com/HerculesWS/Hercules/blob/stable/sql-files/tools/convert_engine_innodb.sql
This converter is useful if you are using MySQL 5.6 or above
There are 4 tables that are commented out
the reason is simple, these 4 tables only read once and forgotten when server is live
since MyISAM is good at reading (SELECT) + smaller disk usage, its no use to convert these 4 tables into InnoDB
3a How to index a table properly
http://mysql.rjweb.org/doc.php/index_cookbook_mysql
http://www.dbta.com/Columns/DBA-Corner/Top-10-Steps-to-Building-Useful-Database-Indexes-100498.aspx
a simple thumb of rule, anything that is SELECT .... WHERE `field` = .....
that `field` has to be index
let's take a look at this PVP Ladder script that use Kill/Death ratio
CREATE TABLE `pvpladder` ( `char_id` INT(11), `name` VARCHAR(23), `kills` INT(11), `death` INT(11), PRIMARY KEY (`char_id`), KEY (`kills`, `death`) ) ENGINE = InnoDB; prontera,155,186,6 script PVP Ladder 1_F_MARIA,{ .@nb = query_sql( "SELECT `name`, `kills`/(`death`+1) FROM `pvpladder` WHERE `kills` > 0 ORDER BY `kills`/(`death`+1) DESC LIMIT 10", .@name$, .@ratio$ ); if ( !.@nb ) { mes "no entry"; close; } mes "Current Ranking :"; for ( .@i = 0; .@i < .@nb; ++.@i ) mes "No."+(.@i +1)+" ["+ .@name$[.@i] +"] "+ .@ratio$[.@i] +" kill"; close; OnPCKillEvent: if ( killedrid == getcharid(3) ) { // killing self should only increase death count. EG: Grand-cross query_sql "INSERT INTO `pvpladder` VALUES ( "+ getcharid(0) +", '"+ escape_sql( strcharinfo(0) )+"', 0,1 ) ON DUPLICATE KEY UPDATE `death` = `death` +1"; end; } query_sql "INSERT INTO `pvpladder` VALUES ( "+ getcharid(0) +", '"+ escape_sql( strcharinfo(0) )+"', 1,0 ) ON DUPLICATE KEY UPDATE `kills` = `kills` +1"; attachrid killedrid; query_sql "INSERT INTO `pvpladder` VALUES ( "+ getcharid(0) +", '"+ escape_sql( strcharinfo(0) )+"', 0,1 ) ON DUPLICATE KEY UPDATE `death` = `death` +1"; end; } This kind of query -> ORDER BY kills/death, needs to index them together like this
KEY (`kills`, `death`) 3b. Why you shouldn't use `char_reg_num_db` table
blame Euphy for spreading this technique
There are 2 reasons why you shouldn't even touch all these variable tables
Reason no.1 This table is sorely meant for server usage
Once these data is loaded, it is process internally, and only save character data according to this configuration
Reason no.2 The `value` field is not index !
This line has ORDER BY `value`, try recheck our main.sql file
CREATE TABLE IF NOT EXISTS `acc_reg_num_db` ( `account_id` INT(11) UNSIGNED NOT NULL DEFAULT '0', `key` VARCHAR(32) BINARY NOT NULL DEFAULT '', `index` INT(11) UNSIGNED NOT NULL DEFAULT '0', `value` INT(11) NOT NULL DEFAULT '0', PRIMARY KEY (`account_id`,`key`,`index`), KEY `account_id` (`account_id`) ) ENGINE=MyISAM; SQL will search through every single line in the `value` field if that column isn't index
Of course you can ... do ALTER table to add KEY to the `value` field
but this table has already optimized in that way for server usage
the more field you index into the table, the more disk usage space it use
Conclusion : If you want to make a custom script, then make a custom table. Leave these table alone !

4. AUTO_INCREMENT
CREATE TABLE `support_ticket` ( `id` INT(11) AUTO_INCREMENT, `title` VARCHAR(70), `message` VARCHAR(255), PRIMARY KEY (`id`) ) ENGINE = InnoDB; In this kind of query that has AUTO_INCREMENT, many people do ....
$support_ticket_id++; query_sql "INSERT INTO `support_ticket` VALUES ( "+ $support_ticket_id +", '"+ escape_sql(.@title$) ... can be optimize .... using NULL
query_sql "INSERT INTO `support_ticket` VALUES ( NULL, '"+ escape_sql(.@title$) ... can retrieve the last row with
query_sql "SELECT MAX(`id`) FROM `support_ticket`", .@id; // ----- OR ----- query_sql "SELECT LAST_INSERT_ID()", .@id;  
Question : This question was asked on eathena forum board
One of my friend touched my custom table and the AUTO_INCREMENT has jump off the value
| 1 | <data set 1> | 2 | <data set 2> | 3 | <data set 3> | 25854 | <data set 4> | 25855 | <data set 5> | 25856 | <data set 6> I want to make the value return back to normal as shown
| 1 | <data set 1> | 2 | <data set 2> | 3 | <data set 3> | 4 | <data set 4> | 5 | <data set 5> | 6 | <data set 6> How to do this WITHOUT losing any of the current data ?
Answer: The trick is ... just drop that column and rebuild it
ALTER TABLE `inventory` DROP COLUMN `id`; ALTER TABLE `inventory` ADD COLUMN `id` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY FIRST; convert the table into MyISAM will process the query much faster

5. How to do IF-ELSE in SQL query ?
Question : I have a PVP ladder script that runs on Points system. Each kill plus 1 point and each death minus 1 point.
The problem is, this query will make the points go into negative value if the player is being kill repeatedly
query_sql "UPDATE `pvp_points` SET `points` = `points` - 1 WHERE `char_id` = "+ getcharid(0); How do I make the points stop at 0 if the player is already at 0 points ?
 
Answer :
query_sql "UPDATE `pvp_points` SET `points` = IF(`points` = 0, 0, `points` - 1) WHERE `char_id` = "+ getcharid(0); query_sql "UPDATE `pvp_points` SET `points` = (CASE WHEN `points` = 0 THEN 0 ELSE `points` - 1 END) WHERE `char_id` = "+ getcharid(0);  
Explanations:
similar to hercules script language,
if (<condition>) <execute true condition>; else <execute false condition>; in SQL language
IF(<condition>, <execute true condition>, <execute false condition>) CASE WHEN <condition> THEN <execute true condition> ELSE <execute false condition> END

5a. How to update multiple rows on different conditions in a single query
This query will update multiple rows on different condition
UPDATE `pvpladder` SET `points` = CASE WHEN `char_id` = 150000 THEN `points` +1 WHEN `char_id` = 150001 THEN `points` -1 END WHERE `char_id` IN (150000,150001); Reference : https://stackoverflow.com/questions/20255138/sql-update-multiple-records-in-one-query

anyone miss meh?

Edit: problem solve 
How to solve this problem, just add new function on luafile514\lua files\SkillInfoz\skillinfo_f.lub
GetSkillScale = function(in_SKID, in_Level) local obj = SKILL_INFO_LIST[in_SKID] local x = 0 local y = 0 if nil ~= obj then obj = SKILL_INFO_LIST[in_SKID].SkillScale end if nil ~= obj then obj = SKILL_INFO_LIST[in_SKID].SkillScale[in_Level] end if nil ~= obj then x = SKILL_INFO_LIST[in_SKID].SkillScale[in_Level].x if nil == x then return 0, 0 else y = SKILL_INFO_LIST[in_SKID].SkillScale[in_Level].y if nil == y then return 0, 0 end end end return x, y end
