[1.7.10] Moving an Entity

[SHiLLySiT]

I'm trying to move an entity when a player right-clicks with an item. It works as intended if the Entity is in a nearby loaded chunk, but if its far enough away, the player has to move a bit before the entity appears after right clicking. Here's the code:

 

public boolean onItemUse(ItemStack itemStack, EntityPlayer player, World world, int x, int y, int z, int side, float offsetX, float offsetY, float offsetZ) {
    if (!player.getEntityWorld().isRemote) {
        if (side == 1) { // only spawn on top of blocks
            EntityExtendedPlayer extPlayer = EntityExtendedPlayer.get(player);
            if (extPlayer.state.pet.hasPet) {
                EntityCorgi corgi = (EntityCorgi) Util.getEntityByUUID(world, extPlayer.state.pet.uuid);
                if (corgi == null) {    
                    Empathy.questManager.spawnCorgi(player, x, y + 1, z);
                } else {
                    corgi.setLocationAndAngles(x, y + 1, z, 0.0F, 0.0F);
                }
            }
        }
    }
    return true;
}

 

Is there a method that I need to call to force an update of sorts?

What is likely occurring is that mobs in not-nearby but still loaded chunks have their AI turned off.  You can issue commands all day long, but they'll never do anything.

Is there a way to force the AI on?

1.7.10 is no longer supported by forge, you are on your own.

How do you do it in 1.10 then?

[Animefan8888]

I'm not sure if this will work or not, but you could subscribe to LivingUpdateEvent and check if the entities aia is disabled and if it is run the update anyway. Though if it does work it may cause lag as all entities will be receiving AI updates every tick.

Also are you sure that the chunk wasn't unloaded?

[SHiLLySiT]

Ah sorry if that wasn't clear in my first post - yes the chunk that the AI is in before attempting to move it is definitely unloaded.

And to be able to load it you will need the chunks coords.

I belive its called a "Lazy Chunk" if my vanilla skillz are right...

a lazy chunk is a chunk that processes redstone, hoppers and such but not entities..

Without mods you can load a 5x5 of lazy chunks using hopper tricks and the center of the 5x5 chunk will turn into an entity processing chunk...

 

btw how can one load a chunk with code? like, i have chunk cord 22,5 and i want to load that..

[Animefan8888]

	Chunk chunk = new Chunk(world, 0, 0);
	if(!chunk.isLoaded()) chunk.setChunkLoaded(true);

Something like this, but you should use

world.getChunkFromBlockCoords()
// or
world.getChunkFromChunkCoords()
