[1.8]Item Explosion upon water contact

[Eixix]

Hey there!

I was wondering whether it's possible to detect when an item is dropped into the water and let the item explode upon impact or not?

Messed a bit around with the onDroppedByPlayer Event, but didn't manage to get it done! 

Thanks for the help,

Eixix

I think you can accomplish this with the onEntityUpdate method available in the item class. You'd have to proactively check for water, though.

Once an item is dropped it become an EntityItem. An EntityItem extends Entity so has access to the isInWater() method to tell you it is in water. If you also want it to explode in rain, use the isWet() method instead. So like diesieben07 says, you should make your item drop your own custom EntityItem that explodes if isInWater() is true (check in the onUpdate() method). For explosions, look at TNT or EntityCreeper.

Thanks for your help! I got a custom EntityItem now, but the thing is, that it will not render, neither i can pick it up once i threw it on the ground.

 

This is my Item Class (ItemSodium.java)

package tv.Tunfisch.HardcoreSilicon.Items;

import net.minecraft.entity.Entity;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import tv.Tunfisch.HardcoreSilicon.Entity.EntitySodium;

public class ItemSodium extends Item{
ItemStack itemSodium;
public ItemSodium(){

}

@Override
public boolean hasCustomEntity(ItemStack stack)
    {
        return true;
    }

@Override
public Entity createEntity(World world, Entity location, ItemStack itemstack)
    {
        return new EntitySodium(world);
    }
}

 

This is my Custom Entity (EntitySodium.java) - side note: I did not yet implement the explosion

package tv.Tunfisch.HardcoreSilicon.Entity;

import net.minecraft.entity.Entity;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import tv.Tunfisch.HardcoreSilicon.Register.ItemRegister;


public class EntitySodium extends EntityItem{

public EntitySodium(World worldIn) {
	super(worldIn);
	setEntityItemStack(new ItemStack(ItemRegister.itemSodium));
}

@Override
public void onEntityUpdate(){
	if (this.inWater){

	}
}

}

 

Thanks for being patient with me im not a native speaker and just began to develop Minecraft Mods

Sorry for answering so late, had to do a lot at university...

Can you describe how to copy them to the new entity?

Thank you!

 

Yep, I'm a total noob, merry christas

 

[Eixix]

You're the real MVP

Ok last question on a very basic thing:

How do I spawn already existing entities? In this case a primed TNT at the location of the Item?

 

Sorry for all the questions, but I'm not really into entities... Is there some kind of documentation for 1.8 modding?

 

Thanks,

Eixix

[Eixix]

So how do I get the coordinates from the EntitySodium transferred to the EntityPrimedTNT?

[Eixix]

But this is an ItemEntity there are no such fields ._. Or I am too dumb to find them...

[Eixix]

Oh for gods sake there was a typo ... How dumb actually... I know basic Java, but I'm struggeling with the weird structure Minecraft has from time to time...

First term computer science...

 

Thanks anyway
