[1.7.10] [solved]customizing damage

knokko · October 5, 2014

hello guys,

I have tried for hours to edit the attack damage a player causes, but it didn't work.

I have tried the LivingHurtEvent and editing event.ammount, but this made the damage infinite.

I have tried player.getEntityAttribute(SharedMonsterAttributes.attackDamage).setBaseValue();, but this only edits the base value, there is almost no difference if I striked with a sword.

Does somebody know a better way to do this?

I have tried the LivingHurtEvent and editing event.ammount, but this made the damage infinite.

That should have worked fine. Show your code?

Here is the code:

I have used system.out.println for better understanding.

 package knokko.rpg.events.living;

import knokko.rpg.RPG;
import knokko.rpg.data.WorldData;
import knokko.rpg.entity.effect.EntityBlood;
import net.minecraft.entity.EntityCreature;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ChatComponentTranslation;
import net.minecraft.util.DamageSource;
import net.minecraft.util.EnumChatFormatting;
import net.minecraftforge.event.entity.living.LivingHurtEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class HurtEvent {
@SubscribeEvent
public void hurtEvent(LivingHurtEvent event){
	if(event.entityLiving != null){
		if(event.source == DamageSource.fall){
			event.setCanceled(true);
		}
		if(event.source.getEntity() instanceof EntityPlayer){
			EntityPlayer player = (EntityPlayer) event.source.getEntity();
			System.out.println("getPlayerStrengt = " + RPG.getPlayerStrengt(player));
			System.out.println("event.amount before multitplying = " + event.ammount);
			event.ammount *= RPG.getPlayerStrengt(player);
			System.out.println("event.amount after multiplying = " + event.ammount);
		}
		if(!event.isCanceled()) {
		float armor = (float) (event.entityLiving.getTotalArmorValue() * 0.04);
		float armor2 = 1 - armor;
		int damage = (int) (event.ammount * armor2);
		if(event.entityLiving instanceof EntityPlayer && event.source.getEntity() instanceof EntityLiving){
			if(!((EntityLiving) event.source.getEntity()).getCustomNameTag().isEmpty()){
				EntityPlayer hurtPlayer = (EntityPlayer) event.entityLiving;
				hurtPlayer.addChatMessage(new ChatComponentTranslation(EnumChatFormatting.RED + "You are hurt for " + damage + " damage by " + ((EntityLiving) event.source.getEntity()).getCustomNameTag()));
			}
		}
		else if(event.entityLiving instanceof EntityPlayer && !(event.source.getEntity() instanceof EntityPlayer) ){
			EntityPlayer hurtPlayer = (EntityPlayer) event.entityLiving;
			hurtPlayer.addChatMessage(new ChatComponentTranslation(EnumChatFormatting.RED + "You are hurt for " + damage + " damage by " + event.source.damageType));
		}
		if(event.source.getEntity() instanceof EntityPlayer){
			EntityPlayer player = (EntityPlayer) event.source.getEntity();
			WorldData.addXP(player, damage);
			WorldData.addRaceXp(player, damage % 3);
		}
		if(event.entityLiving instanceof EntityPlayer && event.source.getEntity() instanceof EntityPlayer){
			EntityPlayer hurtPlayer = (EntityPlayer) event.entityLiving;
			hurtPlayer.addChatMessage(new ChatComponentTranslation(EnumChatFormatting.RED + "You are hurt for " + damage + " damage by " + ((EntityPlayer) event.source.getEntity()).getDisplayName()));
			EntityPlayer attacker = (EntityPlayer)event.source.getEntity();
			attacker.addChatMessage(new ChatComponentTranslation(EnumChatFormatting.GREEN + "You have hit " + hurtPlayer.getDisplayName() + " for " + damage + " damage."));
		}
		else if(event.source.getEntity() instanceof EntityPlayer && ((EntityLiving) event.entityLiving).getCustomNameTag().isEmpty()){
			EntityPlayer attacker = (EntityPlayer) event.source.getEntity();
			attacker.addChatMessage(new ChatComponentTranslation(EnumChatFormatting.GREEN + "You have hit a mob for " + damage + " damage."));
		}
		else if(event.source.getEntity() instanceof EntityPlayer){
			EntityPlayer attacker = (EntityPlayer) event.source.getEntity();
			attacker.addChatMessage(new ChatComponentTranslation(EnumChatFormatting.GREEN + "You have hit " + ((EntityLiving) event.entityLiving).getCustomNameTag() + " for " + damage + " damage."));
		}
		if(event.entityLiving instanceof EntityCreature || event.entityLiving instanceof EntityPlayer){
		if(damage >= 1){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY, event.entityLiving.posZ, 1));
			}
		if(damage >= 2){

		if(damage >= 3){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX + 1, event.entityLiving.posY, event.entityLiving.posZ, 1));
			}
		if(damage >= 4){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX - 1, event.entityLiving.posY, event.entityLiving.posZ, 1));
			}
		if(damage >= 5){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY, event.entityLiving.posZ + 1, 1));
			}
		if(damage >= 6){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY, event.entityLiving.posZ - 1, 1));
			}
		if(damage >= 7){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY, event.entityLiving.posZ, 1));
			}
		if(damage >= {
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY + 0.5, event.entityLiving.posZ, 1));
			}
		if(damage >= 9){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX + 0.5, event.entityLiving.posY, event.entityLiving.posZ, 1));
			}
		if(damage >= 10){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX - 0.5, event.entityLiving.posY, event.entityLiving.posZ, 1));
			}
		if(damage >= 11){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY, event.entityLiving.posZ + 0.5, 1));
			}
		if(damage >= 12){
			event.entityLiving.worldObj.spawnEntityInWorld(new EntityBlood(event.entityLiving.worldObj, event.entityLiving.posX, event.entityLiving.posY, event.entityLiving.posZ - 0.5, 1));
			}
		}
		}
	}
}
}

Here is the important part of the console:

getPlayerStrengt = 1.4107303442451825E15

event.amount before multitplying = 1.5

event.amount after multiplying = 2.11609549E15

I can't really help that the file is not very easy...

TheGreyGhost · October 5, 2014

By crikey dude, if you multiply the damage by 1x10^15, no wonder it does 'infinite damage'

The LivingHurtEvent is working fine, you've done the hard bit already, you just need to figure out why RPG.getPlayerStrength returns

1.4107303442451825E15, which for sure it shouldn't

-TGG

knokko · October 5, 2014

I don't understand what you mean, 1.4107303442451825E15 is a number between 1 and 2, isn't it?

But I don't know why there is an "E" in the double.

RPG.getPlayerStrengt returns that number because I have programmed it that way.

It is bound with several classes and playerdata that is added in livinghurtevent.

Is it so strange it returns a number between 1 and 2?

And do you mean with "1x10^15" 1000000000000000? That would say something.

Here is RPG.java if you need it:

 package knokko.rpg;

	}
	else {
		return 1;
	}
}
private static double getClassMana(String Class){
	if(Class.matches("warrior")){
		return 0.75;
	}
	else if(Class.matches("mage")){

	}
}

Giving the stats is done in the HurtEvent you could allready see.

Thank you for that, now I understand the problem much better.

Now I am going to look what the big number is...

knokko · October 5, 2014

I have found out the whole problem, my xp was far too high.

So the strike was far too strong.

And the getting of xp goes to fase.

Thank you both for help.
