In a TickHander i was checking for entities around the player.

List<Entity> entities = mc.theWorld.getEntitiesWithinAABBExcludingEntity(mc.thePlayer, mc.thePlayer.boundingBox.expand(19.8D, 19.8D, 19.8D));

 

My problem is i want to get only a specific entity out that list.

If its there that do something.

I tryed:

entities.contains(EntityGrunt.class)

entities == new EntityGrunt(mc.theWorld)

entities instanceof EntityGrunt

Nothing worked.

 

The code is working i can print out the list and its shows that there is EntityGrunt in the range.

Thanks!

List<Entity> entities = mc.theWorld.getEntitiesWithinAABBExcludingEntity(mc.thePlayer, mc.thePlayer.boundingBox.expand(19.8D, 19.8D, 19.8D));
EntityLivingBase entity;
while(entities.iterator.hasNext()){
    entity = (EntityLivingBase)entities.iterator.next();
    if(entity instanceof EntityGrunt){
        //sample
    }
}

Thank you but it causes hanging to my game.

The game is still running i can see it on the console, but the screen is freezed.

I discovered that the "while" causes it. 

I wouldn't check for entities on the client world though.

 

Entity entity;
World world = //find some way to initialize the world in your tickhandler without using Minecraft.getMinecraft().theWorld;
if(!world.isRemote) {
List list = world.getEntitiesWithinAABB(EntityItem.class, this._golem.boundingBox.expand(20.0D, 4.0D, 20.0D));
EntityItem entityitem = null;
Iterator iterator = list.iterator();

while (iterator.hasNext()) {
	EntityItem entityitem1 = (EntityItem)iterator.next();
    	entity = entityitem1;
    	break;
}
}

Thank you guys!

The problem seems to be i can't use EntityLivingBase and i missed the break; line.
