[1.7.2] Trying to Insta-Kill Player with potion

[yanksrock1019]

I am trying to make a potion that kills a player/entity instantly. I have some code but it doesn't do anything. Any help?

 

@SubscribeEvent
public void onPotionThrow(LivingUpdateEvent event){
	if (event.entityLiving.isPotionActive(MainClass.instaKill)){

		event.entityLiving.setDead();
}

}

 

[Draco18s]

That code, if it ran, would kill the entity that throws any splash potion

[yanksrock1019]

I assume this is wrong too?

 

@SubscribeEvent
public void onEffect(LivingUpdateEvent event){
	if (event.entityLiving.isPotionActive(PupletItems.potionInstaKill)){

		event.entityLiving.attackEntityFrom(DamageSource.magic, 1.0F);
}

}

Is it doing what you want? No? Then yes, it's wrong. Start adding system.out () statements to see what is going on.

[yanksrock1019]

Still don't know what to do Does it need to be similar to the affectEntity code in the Potion class

 

public void affectEntity(EntityLivingBase par1EntityLivingBase, EntityLivingBase par2EntityLivingBase, int par3, double par4)
    {
        int j;

        if ((this.id != heal.id || par2EntityLivingBase.isEntityUndead()) && (this.id != harm.id || !par2EntityLivingBase.isEntityUndead()))
        {
            if (this.id == harm.id && !par2EntityLivingBase.isEntityUndead() || this.id == heal.id && par2EntityLivingBase.isEntityUndead())
            {
                j = (int)(par4 * (double)(6 << par3) + 0.5D);

                if (par1EntityLivingBase == null)
                {
                    par2EntityLivingBase.attackEntityFrom(DamageSource.magic, (float)j);
                }
                else
                {
                    par2EntityLivingBase.attackEntityFrom(DamageSource.causeIndirectMagicDamage(par2EntityLivingBase, par1EntityLivingBase), (float)j);
                }
            }
        }
        else
        {
            j = (int)(par4 * (double)(4 << par3) + 0.5D);
            par2EntityLivingBase.heal((float)j);
        }
    }

Don't just copy paste code. You don't need an event handler, your Potion class gives you all the hooks you need:

 

isInstant

- if this returns true your potion does not apply a PotionEffect to the entity, it just acts as a one-off effect (like instant health).

 

affectEntity

- Called to apply the one-off effect if

isInstant

is true

 

isReady

- Called every tick if your potion is active on an entity (

isInstant

must be false). Arguments are

ticksLeft

and

amplifier

. If this method returns true,

performEffect

is called so it can perform the effect this tick.

 

Edit: Oh, and this:

Don't tell me to learn the basics of java, I already know.

cannot be taken seriously at all if you produce a thread like this.

What does this have to do with basic java.  Also, just because I did something wrong, doesn't mean I copy pasted something

[yanksrock1019]

Well yes it was copy in paste, but if you read the question, I was asking if I should use something similar to that code.

[yanksrock1019]

Also, I found what you described, understand what it does in vanilla, but still don't know what to do in my case

[yanksrock1019]

Not working.  Not sure if it's because I'm applying the effect via command.  If so, how do I create the physical splash potion.  Is it just an Item

 

@Override
public boolean isInstant()
    {
        return true;
    }


public void affectEntity(EntityLivingBase entity1, EntityLivingBase entity2, int par3, double par4){

	entity2.setDead();
}

[yanksrock1019]

/effect {player} 30 (the Id of my potion)

[yanksrock1019]

*bump*

[yanksrock1019]

I'm also having a hard time creating the actual potion item itself.  When I try to set its creative tab, it adds all the potions to my creative tab

[yanksrock1019]

*bump*

[Purplicious_Cow]

Share the code you are having problems with. You seem to have two issues?

1) creating the actual potion item itself (are you having problems with the Potion class?)

2) something to do with 'adds all the potions to my creative tab'. Not sure what that means....

[yanksrock1019]

Sorry, here, this is the actual ItemPotion class I made for the splash potion. And what I mean by the creative tab is, I have my own creative tab, and whenever I add this to that creative tab, it adds all potions that actually exist in vanilla, to my tab

package com.puplet.items;

import com.puplet.blocks.PupletBlocks;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.EnumAction;
import net.minecraft.item.Item;
import net.minecraft.item.ItemPotion;
import net.minecraft.item.ItemStack;

public class InstaPotion extends ItemPotion{

public InstaPotion(){


}

 public EnumAction getItemUseAction(ItemStack par1ItemStack)
    {
        return EnumAction.drink;
    }

 public static boolean isSplash(int par0)
    {
        return true;
    }


}

[yanksrock1019]

I think I may be missing something here, because I see no answer in getSubItems. Please point out what you are talking about

[yanksrock1019]

So why when I use this.setCreativeTabs it adds all vanilla potions to my tab

[Draco18s]

because: ItemPotion#getSubItems adds all possible potions to the list.

[knokko]

Why are you making a custom potion effect?

You can just use /effect player 7 1 100 to give somebody a good strike.

Or in code : entity.setDead()

[yanksrock1019]

You're right, what I really wanted to do was to just make it into a potion

[knokko]

As potioneffect, you can use new PotionEffect(7, 1, 100);
