Thread: Multi barrage on NPC (Project Insanity)

This snippet will show you how to add multi spells on NPCs (it may have a few bugs):

Add this import at the top of CombatAssistant:

Code:

import server.model.npcs.NPC;

Add these methods in CombatAssistant.java

Code:

public void multiSpellEffectNPC(int npcId, int damage) {					
		switch(c.MAGIC_SPELLS[c.oldSpellId][0]) {
			case 12891:
			case 12881:
				if (Server.npcHandler.npcs[npcId].freezeTimer < -4) {
					Server.npcHandler.npcs[npcId].freezeTimer = getFreezeTime();
				}
			break;
		}	
	}

public boolean checkMultiBarrageReqsNPC(int i) {
		if(Server.npcHandler.npcs[i] == null) {
			return false;
		} else {
			return true;
		}
	}

public void appendMultiBarrageNPC(int npcId, boolean splashed) {
		if (Server.npcHandler.npcs[npcId] != null) {
			NPC n = (NPC)Server.npcHandler.npcs[npcId];
			if (n.isDead)
				return;
			if (checkMultiBarrageReqsNPC(npcId)) {
				c.barrageCount++;
				Server.npcHandler.npcs[npcId].underAttackBy = c.playerId;
				Server.npcHandler.npcs[npcId].underAttack = true;
				if (Misc.random(mageAtk()) > Misc.random(mageDef()) && !c.magicFailed) {
					if(getEndGfxHeight() == 100){ // end GFX
						n.gfx100(c.MAGIC_SPELLS[c.oldSpellId][5]);
					} else {
						n.gfx0(c.MAGIC_SPELLS[c.oldSpellId][5]);
					}
					int damage = Misc.random(c.MAGIC_SPELLS[c.oldSpellId][6]);
					if (Server.npcHandler.npcs[npcId].HP - damage < 0) { 
						damage = Server.npcHandler.npcs[npcId].HP;
					}		
					c.getPA().addSkillXP((c.MAGIC_SPELLS[c.oldSpellId][7] + damage*Config.MAGIC_EXP_RATE), 6); 
					c.getPA().addSkillXP((c.MAGIC_SPELLS[c.oldSpellId][7] + damage*Config.MAGIC_EXP_RATE/3), 3);
					Server.npcHandler.npcs[npcId].handleHitMask(damage);
					Server.npcHandler.npcs[npcId].dealDamage(damage);
					c.totalPlayerDamageDealt += damage;
					multiSpellEffectNPC(npcId, damage);
				} else {
					n.gfx100(85);
				}			
			}		
		}	
	}

Then, search for:

Code:

} else if (Server.npcHandler.npcs[i].npcType == 2881 || Server.npcHandler.npcs[i].npcType == 2882) {
					damage = 0;
					magicFailed = true;
				}

Under that, add

Code:

for (int j = 0; j < Server.npcHandler.npcs.length; j++) {
					if (Server.npcHandler.npcs[j] != null && Server.npcHandler.npcs[j].MaxHP > 0) {
						int nX = Server.npcHandler.npcs[j].getX();
						int nY = Server.npcHandler.npcs[j].getY();
						int pX = Server.npcHandler.npcs[i].getX();
						int pY = Server.npcHandler.npcs[i].getY();
						if ((nX - pX == -1 || nX - pX == 0 || nX - pX == 1) && (nY - pY == -1 || nY - pY == 0 || nY - pY == 1)) {
							if (multis() && Server.npcHandler.npcs[i].inMulti()) {
								Client p = (Client) Server.playerHandler.players[c.playerId];
								appendMultiBarrageNPC(j, c.magicFailed);
								Server.npcHandler.attackPlayer(p, j);
							}
						}
					}
				}

Lastly, in NPC.java add:

Code:

public void dealDamage(int damage) {
			if (damage > HP) {
				damage = HP;
			}
			HP -= damage;
	}

That should be it, tell me if I forgot any methods and I will post them ASAP.
