Let Blocks react on entity impact?

[ItsAMysteriousYT]

I wanna add some cool effect too my Block when an entity collides with it e.g a minecart. What is the right place to do that?

The following advice assumes you're using 1.8. It's pretty similar in 1.7.10.

 

Block#onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn)

is called when an

Entity

collides with the

Block

. The other overload is only called when an

Entity

walks on top of the

Block

.

 

An

Entity

will only collide with a

Block

if it has a bounding box smaller than a full cube. An offset of 0.01 on each side is enough to allow collisions.

Thanks Awesome help - especially that the boundingbox must be smaller thatn a block!!
