Multi-Block Structures (like waterwheels)

[MikeZ]

Hello,

I wondered, how multi-block structures are made.

So that a player places a specific structure of blocks, and then a single block appears. e.g. Water Wheels from Immersive Engineering.

 

Does anyone have a tutorial or tips for that project. It should be for 1.7.10?

 

Thanks,

Mike

Unfortunatelly I can not provide you with tutorial, but I figured out that Immersive Engineering mod is open source so I suggest you to take a look to their code and maybe you will find something useful to your goals. :-)

It's not that hard, if you are a little bit experienced with rendering. Have a core block from which you check if a specific pattern of blocks is correct each tick, and if it is, spawn your desired entity/tile-entity. In case of a water wheel you would need a custom rendered entity with a rotating animation, with ghostly, fully transparent blocks around it's base to give it a hitbox. When one of these blocks is broken, you can either drop all the water wheel components, or save the broken blok position to respawn the pattern with the missig piece. That's what i would have tried, even though i myself probably wouldn't jave bothered with this at all until i learn something good about rendering.

Don't check every tick.  Only check when your block gets a neighborChanged update
