[SOLVED] Entity Motion Not Updating

Recommended Posts

Hello,

 

Today I seek help in making a block that launches ThrowableEntitys at hostile mobs. It is a little like a snowman, except it is a block and its position is constant. The method i am using is as follows:

setThrowableHeading()

 

The problem is that it continues to lock onto the possession of the first mob it encounters, and will throw only at that position, even after the mob is dead.

 

The first thing that would come to one's mind when reading my code sample is that I only reference the first index of the list list.get(0), but this is not causing the "locked aim" because I use list.clear() after spawning the entity, and when the mob is dead, the first index of the list will obtain a new value. 

 

[Forge 1.8.9]

 

Spoiler

//Class extends net.minecraft.block.Block
	
	@Override
	public void updateTick(World worldIn, BlockPos pos, IBlockState state, Random rand){
		
		int xCoord = pos.getX();
		int yCoord = pos.getY() + 1;
		int zCoord = pos.getZ();
		
		List<EntityMob> list = worldIn.getEntitiesWithinAABB(EntityMob.class, new AxisAlignedBB((float) (xCoord + 40), (float) (yCoord + 40), (float) (zCoord + 40), (float) (xCoord - 40), (float) (yCoord - 4), (float) (zCoord - 40)));
		
		if(!list.isEmpty()){
			
			EntityGranade e = new EntityGranade(worldIn, (double)xCoord, (double)(yCoord + 1), (double)zCoord);
			
			e.setThrowableHeading(list.get(0).posX, list.get(0).posY, list.get(0).posZ, 5, 0);
		
			worldIn.spawnEntityInWorld(e);
		}
		list.clear();
		worldIn.scheduleUpdate(pos, this, 100);
	}

I got it :o

 

List<EntityMob> list = worldIn.getEntitiesWithinAABB(EntityMob.class, new AxisAlignedBB((float) (xCoord + 40), (float) (yCoord + 40), (float) (zCoord + 40), (float) (xCoord - 40), (float) (yCoord - 4), (float) (zCoord - 40)));
		
		if(!list.isEmpty()){
			
			EntityMob target = list.get(0);
		
			EntityGrenade entitysnowball = new EntityGrenade(worldIn, xCoord, yCoord, zCoord);
	        double d0 = target.posY + (double)target.getEyeHeight() - 1.100000023841858D;
	        double d1 = target.posX - pos.getX();
	        double d2 = d0 - entitysnowball.posY;
	        double d3 = target.posZ - pos.getZ();
	        float f = MathHelper.sqrt_double(d1 * d1 + d3 * d3) * 0.2F;
	        entitysnowball.setThrowableHeading(d1, d2 + (double)f, d3, 4, 0);
	        worldIn.spawnEntityInWorld(entitysnowball);
		}

    • As title says. Already had to get some work arounds to get java working, and I don't have the ability to upgrade to windows 10.
    • I am having an issue running a server with my mod. I know that I am reaching across sides somewhere in my Mod, but could not find where this error is occurring in my mod. The crash report that I have attached below mentioned that it involved the LocalPlayer. However, when I searched my mod for LocalPlayer, I only found one case in the event that I have attached below. Can you find where I errored?   Crash Report: ---- Minecraft Crash Report ---- // I bet Cylons wouldn't have this problem.

    • That's because redstone doesn't use tile entities. It's all handled by blockstates. There's no way to achieve what you want as far as I know.
