[1.12.2] stop snow falling on custom block

[Xenoamor]

Hi Guys,

 

How can I stop snow settling on a custom block. As I'm rendering it differently it does not look right with the snow on top of it

 

Many thanks,

Snow settling happens in WorldServer#updateBlocks() - look for the profiler section marked "iceandsnow".  Looking at that code, there are no specific snow-formation events fired, so your options are:

• Override neighborChanged() in your custom block's class (the method is deprecated, but overriding it is OK).  In the override, you can check if the block above your block has become a snow layer, and if so, remove it.  (note: that's extra block update work, which might become a performance issue if you plan to have a lot of your custom block in the world)
• Have your custom block emit enough light to prevent snow formation (light level of 10, I believe).  Might not be practical.

• Enhancement request or PR to Forge to have a custom snow formation event fired.  Not sure if that would fly.

As far as I am aware snow doesn't fall on blocks that are not full cubes(return false in Block#isFullCube)

Yes, you're right (although the method to use is Block#getBlockFaceShape, as diesieben07 pointed out).  If it's not SOLID, snow won't settle.

 

Of course, changing that can have other effects (e.g. torch/button placement), so might not be appropriate.
