I was if there currently is any way to modify the behavior of a block, more specifically "do something to the player when she touches the block". Cervator told me to look for uses of the "isPenetrable" method of "Block", but these seem to be scattered across the codebase, which would mean that I'd have to implement that behavior somewhere in the class that detects the collision (hell no x.x). Am I missing something, or is this simply something that hasn't been thought of yet?
