I have created a throw-able bomb(grenade i guess) but it doesn't explode if i throw it forward or down i have to throw it up into the air and it must com back down to the ground it doesn't even work if i throw it up at a tree it has to come back to the ground.

 

EntityBomb:

package dudesmods.lozmod;

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.DamageSource;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.Explosion;
import net.minecraft.world.World;

public class EntityBomb extends EntityThrowable {

public EntityBomb(World par1World) {
	super(par1World);
}

public EntityBomb(World par1World, EntityLiving par2EntityLiving) {
	super(par1World, par2EntityLiving);
}

public EntityBomb(World par1World, double par2, double par4, double par6) {
	super(par1World, par2, par4, par6);
}

protected void onImpact(MovingObjectPosition par1MovingObjectPosition) {
	if (par1MovingObjectPosition.entityHit != null) {

		par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), 0);
		}
	if(this.worldObj.isRemote) {
		explode();
	}

	if(!this.worldObj.isRemote) {
		this.setDead();
	}
}

private void explode() {
	if(!exploded) {
		exploded = true;
		worldObj.createExplosion(this, posX, posY, posZ, 4.0F, true);
	}
}

boolean exploded;

}

 

ItemBomb:

package dudesmods.lozmod;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class ItemBomb extends Item {

public ItemBomb(int par1) {
	super(par1);
	setMaxStackSize(32);
	setCreativeTab(LOZmod.tabLozMod);
	}

public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer entityplayer) {

	if(!entityplayer.capabilities.isCreativeMode) {
		--itemstack.stackSize;
	}

	if (!world.isRemote) {
		world.spawnEntityInWorld(new EntityBomb(world, entityplayer));
	}

	return itemstack;
}


}

 

ModClassStuffs:

bomb = new ItemBomb(16501).setUnlocalizedName("bomb").setMaxStackSize(32);

EntityRegistry.registerGlobalEntityID(EntityBomb.class, "bomb", EntityRegistry.findGlobalUniqueEntityId());
	EntityRegistry.registerModEntity(EntityBomb.class, "bomb", 2, this, 20, 2, false);

(im aware i have no RenderingRegistry thing, it shows up as a white box and i'm fine with that until i get this to work.

Anyone?

If I had to take a shot in the dark, I'd say that it might be because the worldObj variable isn't set in time for the onImpact to know what it is. Try adding System.out.println(worldObj); in the onImpact method.

When just thrown i get:

2013-05-12 17:00:16 [iNFO] [sTDOUT] net.minecraft.world.WorldServer@55a8c7aa

 

But when i throw it up, it comes down, and explodes i get:

2013-05-12 17:00:09 [iNFO] [sTDOUT] net.minecraft.world.WorldServer@55a8c7aa
2013-05-12 17:00:09 [iNFO] [sTDOUT] net.minecraft.client.multiplayer.WorldClient@4ba70c56

Yea, that's what I figured. It sounds like your worldObj isn't being updated. There's your problem. =) Good luck!

So...

what do i do?

If I'm correct, you need to add in read and write NBT methods, so that information about the entity can be transferred.

NBT is beyond me.

all i know is that it stores info like inventories and stuff.

Take a look at the EntityLargeFireball class as an example.

Still not working.

Do you have a PacketHandler clientside? I'm not sure how to do it using Forge Hooks (I'm pretty sure there is) but for all my mods I modify NetClientHandler in the receivedEntityPacket method.

My brain is starting to hurt a little. I've never had to use packet handlers in minecraft.
