Thanks that works perfectly. Here is the override in case it helps anyone. @Override public AxisAlignedBB getCollisionBoundingBox(World worldIn, BlockPos pos, IBlockState state) { float f = 1.0F; IBlockState iblockstate = worldIn.getBlockState(pos); if (iblockstate.getBlock() == this) { EnumSamBlockTypes btype = (EnumSamBlockTypes)(iblockstate.getValue(BlockType)); switch (btype) { case SAMSTONE_SLAB: f = 0.5F; default: } } return new AxisAlignedBB((double)pos.getX() + this.minX, (double)pos.getY() + this.minY, (double)pos.getZ() + this.minZ, (double)pos.getX() + this.maxX, (double)((float)pos.getY() + (float) f), (double)pos.getZ() + this.maxZ); }

Hello, I am new here. I am working my way through the book 'Minecraft Mod development in 24 hours' and it's pretty great but unfortunately it was written before 1.8. I am learning a lot converting all the examples over but I have gotten a little stumped after making my own metadata block that is two full size blocks and a half height slab. Everything looks great and places great but when I walk over the blocks it seems like it is basing the collision detection on the block I am looking at rather than the block I am standing on. For example, if I look at a half height block I can walk onto a full height block, and if I look at a full height block I can't walk onto a half height block. Any ideas? Block Class:
