How do you add a custom hitbox to a block?

HI, I've added a block with a custom block model, but I just realized that you need to add a custom hitbox as well, for things like lighting to work properly.

Hi!

You need to override the Voxelshape of your block.

I don't know how the Method is named, but it's something like getShape. Search in your IDE for overridable methods that contain"shape" in their name (In Eclipse: Alt+Shift+S+V I think and then type "*shape" )

Thanks!

Where does getShape() get called from?

[OutCraft]

I don't know.

What do you want to achieve?

Set a custom hitbox for my block, but what class needs to call the function and what schould be the parameters. I tried to look into the minecraft code for an example of the method being called there, but couldn't find one.

You need to override the method getShape or getVoxelShape or something like that in your Block class and return your own VoxelShape

For an example look into the slab class (that all the slabs extend)

When I try @Override getState() I get this error: "error: getShape(BlockState,BlockGetter,BlockPos,CollisionContext) in CaoutchoucDrain cannot override getShape(BlockState,BlockGetter,BlockPos,CollisionContext) in BlockBehaviour".

Solved it!
