Hey, I'm having trouble figuring out how to make my custom portal teleport non-player entities and players in and out of my custom dimensions. I so far have this but it's cloning the non-player entities and causing a lot of lag, anyone know what I'm doing wrong?

 

	@Override
public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn) {
	if (entityIn.ridingEntity == null && entityIn.riddenByEntity == null) {
		int id = ZeroQuest.NillaxID;
		if (entityIn.dimension == id) {
			id = 0;
		}
		if (entityIn instanceof EntityPlayerMP) {

			EntityPlayerMP player = (EntityPlayerMP) entityIn;
			MinecraftServer mcServer = player.mcServer;

			if (player.timeUntilPortal > 0) {
				player.timeUntilPortal = 10;
			}
			else if (player.dimension != ZeroQuest.NillaxID) {
				player.timeUntilPortal = 10;
				player.mcServer.getConfigurationManager().transferPlayerToDimension(player, ZeroQuest.NillaxID, new TeleporterNillax(mcServer.worldServerForDimension(ZeroQuest.NillaxID)));
			}
			else {
				player.timeUntilPortal = 10;
				player.mcServer.getConfigurationManager().transferPlayerToDimension(player, 0, new TeleporterNillax(mcServer.worldServerForDimension(0)));
			}
		}
		else {
			travelToDimension(entityIn, id);
		}
	}
}

private void travelToDimension(Entity entity, int id) {
	if (!entity.worldObj.isRemote && !entity.isDead) {
		entity.worldObj.theProfiler.startSection("changeDimension");
		MinecraftServer minecraftserver = MinecraftServer.getServer();
		int j = entity.dimension;
		WorldServer worldserver = minecraftserver.worldServerForDimension(j);
		WorldServer worldserver1 = minecraftserver.worldServerForDimension(id);
		entity.dimension = id;

		if (j == 1 && id == 1) {
			worldserver1 = minecraftserver.worldServerForDimension(0);
			entity.dimension = 0;
		}

		entity.worldObj.removeEntity(entity);
		entity.isDead = false;
		entity.worldObj.theProfiler.startSection("reposition");
		entity.timeUntilPortal = 10;
		minecraftserver.getConfigurationManager().transferEntityToWorld(entity, j, worldserver, worldserver1, new TeleporterNillax(worldserver1));
		entity.worldObj.theProfiler.endStartSection("reloading");
		Entity entity1 = EntityList.createEntityByName(EntityList.getEntityString(entity), worldserver1);

		if (entity1 != null) {
			entity1.copyDataFromOld(entity);

			if (j == 1 && id == 1) {
				BlockPos spawnPoint = worldserver1.getSpawnPoint();
				spawnPoint = entity.worldObj.getTopSolidOrLiquidBlock(spawnPoint);
				entity1.setLocationAndAngles(spawnPoint.getX(), spawnPoint.getY(), spawnPoint.getZ(), entity1.rotationYaw, entity1.rotationPitch);
			}

			worldserver1.spawnEntityInWorld(entity1);
		}

		entity.isDead = true;
		entity.worldObj.theProfiler.endSection();
		worldserver.resetUpdateEntityTick();
		worldserver1.resetUpdateEntityTick();
		entity.worldObj.theProfiler.endSection();
	}
}

You don't put any kind of cooldown on transferring non-player entities.

When I remove the cooldowns, it causes lag and doesn't allow the entity to move.

Remove what cooldown?  The only cooldown you have is for players.

I removed the cooldown from the non player entities

The cooldown for non-player entities is here

 

			entity.worldObj.removeEntity(entity);
		entity.isDead = false;
		entity.worldObj.theProfiler.startSection("reposition");
		entity.timeUntilPortal = 10; <<<<<
		minecraftserver.getConfigurationManager().transferEntityToWorld(entity, j, worldserver, worldserver1, new TeleporterNillax(worldserver1));
		entity.worldObj.theProfiler.endStartSection("reloading");
		Entity entity1 = EntityList.createEntityByName(EntityList.getEntityString(entity), worldserver1);

 

I removed it and it causes even more lag spikes and it's causing a "cloning" of the entity that entered the portal on both sides of the dimensions
