Skill unit flag + source modifications

[Naruto 37]

Hi so Ive been working on making a universal skill for some unts....

In our database we have this section under a few skills who use the unt system ;

	Unit: {
		Id: 0x86
		Layout: 3
		Interval: 100
		Target: "Enemy"
	}

 

However we only have the option of giving a flag to the Id, unlike range and layout who can be seperated like so : 

	Unit: {
		Id: 0xbb
		Layout: {
			Lv1: 1
			Lv2: 1
			Lv3: 1
			Lv4: 2
			Lv5: 2
			Lv6: 2
			Lv7: 3
			Lv8: 3
			Lv9: 3
			Lv10: 4
		}
		Interval: -1
		Target: "All"
		Flag: {
			UF_PATHCHECK: true
		}
	}

 

Adding a skill level modifier is possible, but heres something we can all do:

 

Take a look at the use of flag

	Unit: {
		Id: [ 0x86, 0xf4 ]
		Layout: 3
		Interval: 100
		Target: "Enemy"
	}

Alone it will have no effect on your skill and just serves its own purpose with whatever its told to do in the src.. ( Might wanna look at the skill). . . 

 

 

So warp portal uses 2 effects, the pulse then the stand still which are 2 different unts

case UNT_WARP_ACTIVE:
				// warp portal opens (morph to a UNT_WARP_WAITING cell)
				group->unit_id = skill->get_unit_id(group->skill_id, 1); // UNT_WARP_WAITING
				clif->changelook(&su->bl, LOOK_BASE, group->unit_id);
				// restart timers
				group->limit = skill->get_time(group->skill_id,group->skill_lv);
				su->limit = skill->get_time(group->skill_id,group->skill_lv);
				// apply effect to all units standing on it
				map->foreachincell(skill->unit_effect,su->bl.m,su->bl.x,su->bl.y,group->bl_flag,&su->bl,timer->gettick(),1);
			break;

this is the transition 

				group->unit_id = skill->get_unit_id(group->skill_id, 1); // UNT_WARP_WAITING
				clif->changelook(&su->bl, LOOK_BASE, group->unit_id);

 

 

So you could do this : 

 

				group->unit_id = skill->get_unit_id(GS_DESPERADO, 1); 

 

looking at GS_DESPERADO in my db

	Unit: {
		Id: [ 0x86, 0xf4 ]
		Layout: 3
		Interval: 100
		Target: "Enemy"
	}

I added the flag for some black fire i dont know

 

 

 

So my use is to have a reusuable skill.... a throwing animation that lays down whatever effect i want it too

 

however being reduced to 1 flag i can only attach one to the base throwing animation...

 

so by making new skills , or just adding them next to skills that wont bother you, 

 

 

you can potentially change your skill effects however you want....

 

 

 

And the timer is like so : 

limit = skill->get_time(skill_id,skill_lv);

case AL_WARP:
			val1=skill_lv+6;
			if(!(flag&1)) {
				limit=2000;
			} else { // previous implementation (not used anymore)
				//Warp Portal morphing to active mode, extract relevant data from src. [Skotlex]
				struct skill_unit *su = BL_CAST(BL_SKILL, src);
				if (su == NULL)
					return NULL;
				group = su->group;
				src = map->id2bl(group->src_id);
				if (src == NULL)
					return NULL;
				val2 = group->val2; //Copy the (x,y) position you warp to
				val3 = group->val3; //as well as the mapindex to warp to.
			}
			break;

 

so back check for flag.... 

Quote

 * flag&1 is used to determine when the skill 'morphs' (Warp portal becomes active, or Fire Pillar becomes active)

 

 

So this is how we do it the normal way : 

skill.c

add your new one : 

		case MG_FIREWALL:
			if(sc && sc->data[SC_VIOLENTGALE])
				limit = limit*3/2;
			val2=4+skill_lv;
			break;
		case BS_HAMMERFALL:
			if(!(flag&1))
				limit=2000;
			break;

 

Im using bs_hammerfall in this case 

 

limit is the timer to change

 

I gave it its own space for testing... but add it to ground skills

		case BS_HAMMERFALL:
			skill->unitsetting(src,skill_id,skill_lv,x,y,0);
			break;
		case WZ_ICEWALL:
			flag |= 1;
			if( skill->unitsetting(src,skill_id,skill_lv,x,y,0) )
				map->list[src->m].setcell(src->m, x, y, CELL_NOICEWALL, true);
			break;

 

and finally the unt I attached to it from the skill_db

{
	Id: 110
	Name: "BS_HAMMERFALL"
	Description: "Hammer Fall"
	MaxLevel: 5
	Range: -9
	Hit: "BDT_SKILL"
	SkillType: {
		Place: true
	}
	SkillInfo: {
		IgnoreLandProtector: true
		AllowReproduce: true
	}
	AttackType: "Weapon"
	Element: "Ele_Weapon"
	KnockBackTiles: 2
	SkillData1: 6000
	SkillData1: 2000
	CoolDown: 0
	Requirements: {
		SPCost: 15
	}
	Unit: {
		Id: 0x10a
		Range: 2
		Layout: 3
		Interval: 100
		Target: "Enemy"
		Flag: {
			UF_SKILL: true
		}
	}
},

I made this one

		Id: 0x10a

back in skill.c

			case UNT_MOLOTOV:
				group->unit_id = skill->get_unit_id(GS_DESPERADO, 1);
				clif->changelook(&su->bl, LOOK_BASE, group->unit_id);
				group->limit = skill->get_time(group->skill_id,group->skill_lv);
				su->limit = skill->get_time(group->skill_id,group->skill_lv);
				map->foreachincell(skill->unit_effect,su->bl.m,su->bl.x,su->bl.y,group->bl_flag,&su->bl,timer->gettick(),1);
			break;

 

this is dirty but working, need to clean it up but im going to bed now o/

 

 

last thing I seperated them like this so i can reuse the same skill effect i use for throwing in a place skill : 

Earlier i said we seperated the groud placement, well lets go do this to it

 

		case BS_HAMMERFALL:
			if (pc->checkskill(sd, BS_HAMMERFALL) == 1)
			skill->unitsetting(src,skill_id,skill_lv,x,y,0);
			if (pc->checkskill(sd, BS_HAMMERFALL) == 2)
			skill->unitsetting(src,MG_FIREWALL,skill_lv,x,y,0);
			break;

Updates :

			case UNT_MOLOTOV:
				group->unit_id = skill->get_unit_id(GS_DESPERADO, 1);
				clif->changelook(&su->bl, LOOK_BASE, group->unit_id);
				group->limit = skill->get_time(group->skill_id,group->skill_lv);
				su->limit = skill->get_time(group->skill_id,group->skill_lv);
			break;

2 bottom lines reset the limit timer we used earlier to make the old unt dissipate

 

I was having trouble linking multiple skills together... no idea what to do about it

ex: 

Using hammer fall animation slot ( unt place animation + screen shake) 

using it like this

	case BS_HAMMERFALL:
			if (pc->checkskill(sd, BS_HAMMERFALL) == 1)
			skill->unitsetting(src,skill_id,skill_lv,x,y,0);
			if (pc->checkskill(sd, BS_HAMMERFALL) == 2)
			skill->unitsetting(src,UT_MOLOTOV,skill_lv,x,y,0);
			break;

 

and trying to get the second bounce to effect skilldata1 time? I can make it dissapear a number of ways but couldnt attach a timer to it...

 

Using it alone like warp portal, making timed skills possible i just couldnt chain it anymoe 😕

 

 

 

 

probably make some really cool skills using it... 

 

I was gonna rip it apart and remove flag for a skill lvl but meh...  i dont know about doing both. . .
