Okay, i fixed it! Apparently i had forgotten an @Override for the "onEntityCollidedWithBlock" function.

First of all, thanks for the reply This is even before i do the teleport function. So, i'm not sure what you mean with "they are empty"? The problem is that both "public void breakBlock()" and "public void onEntityCollidedWithBlock()" have the same code: TilePortalPortal dummy = (TilePortalPortal)world.getBlockTileEntity(x, y, z); if(dummy != null && dummy.getCore() != null) dummy.getCore().getMasterClass().teleport(colEntity); Now somehow, the entityCollided function gives me another (new?) tileEntity back, whilst the breakBlock function gives me exactly what i want: the existing tileEntity on those coördinates. What is the difference between these functions?

Hello everyone, First mod, but not my first run in with Java. I'm trying to get a portal-like object in my world. I've followed a tutorial for creating multiblock objects which helped me out pretty good. However, there's a weird thing here. My multiblock consists of 3 objects: portalCore, portalDummy and portalPortal (oh, the name) Anyway, The core block holds all the variables, to where the portal links e.d. The dummy is just the ring of the portal, which transfers all the functions (redstone) to the core block. portalPortal is the block that you actually walk trough. It is generated a bit later than the dummy and core. (Only on redstone signal) They are all three BlockContainers, and all three have a tile behind them. The problem i'm having now is that when i break the portalPortal block, it works perfectly. The block searches the tileEntity needed, which in term searches the core block(because of stored data) telling the core block to turn the portal off. However, when i walk trough the block (onEntityCollidedWithBlock), the exact same function now returns a completely new TilePortalPortal object. This i know because the coreX, coreY and coreZ are emtpy. I will post the class PortalPortalBlock (the block) and TilePortalPortal (the tileEntityClass) below. Please excuse my names, i haven't decided on a good naming-directive for my mods.
