Hi,

what is the best way to create a bounding box for a model bigger than one block. For example, I have a block with a TileEntitySpecialRenderer creating a model of 1x3 (width x height). How can I set the according boundaries. I looked at the tutorial about Multiple blocks structure and the usage of gag-blocks http://www.minecraftforge.net/wiki/Multiple_blocks_structures, but i also read about the method addCollisionBoxesToList(). In the case of the later one i would need some explanation on how it is working and how to set the bounding box correctly and if it is even useful for my case.

I wouldn't use a bounding box greater than a single cube (with slight exceptions, such as a fence, which is why bounding boxes can be up to about 1.5 blocks tall, more than that and the game caps the height, though I am unsure of the precise value.  Width/depth are likewise capped to a single block).

 

What you want to do is something like the bed or door, where the primary block spawns the second (and in your case, third) blocks when placed, and if any of them are broken, it breaks all of them.

I looked at the door but since I only have one block with a high model, would it make sense to seperate the model and create multiple blocks or should i use invisble blocks like in the tutorial linked?

Whichever you want to.  It doesn't really matter a whole lot, but the invisible blocks method might be cheaper in terms of rendering.
