I've looked and looked and looked but I can't find an answer in the code, so I'm turning here. What I want to do is make it so that blocks are affected by gravity(Similarly to sand). The issue is, I want to use pre existing blocks like grass and dirt and whatnot, and I don't want to edit or override any base class files to do it. Is there anything I can do, or am I just going to have to edit some base class files?
