I have an item that spawns a Snowman when right clicked, however, the snowman vanishes after between 1/2 and 2 seconds.

Here is my code:

 

@Override
public ItemStack onItemRightClick(ItemStack is, World world, EntityPlayer player){
if (!world.isRemote)
        {
        	Entity entity=new EntitySnowman(world);
        	entity.posX=player.posX;
        	entity.posZ=player.posZ;
            	entity.posY=player.posY;
                world.spawnEntityInWorld(entity);
        }
        return is;
}

 

If there's any more info you need, please, let me know.

Are you on Peaceful mode while testing this? Scratch that, I had a brain fart and forgot that EntitySnowman is the snow golem. I thought it was a custom entity for some reason.

Sorry, I'm relatively new to modding, what does world.isRemote?

World#isRemote is equivalent to checking whether you are on the logical client side.

Maybe you could try world.joinEntityInSurroundings(entity). Try to replace world.spawnEntity(entity) with this.

use entity.setPosition(x, y, z); instead of

entity.posX=player.posX;

entity.posZ=player.posZ;

entity.posY=player.posY;

Check your console, there maybe an error inside it.

Im fairly sure he just needs to use setPosition i ran into this problem when i first started messing with entitys. Im not sure why but when setting the position using entity.pos = the entity spawns at that position but immediately warps to 0, 0, 0 and falls out of the world.
