Is there anyway I can make only blocks go through another and users stay? I want to make it where the bottom of doom-spire brick battle is there, but you don't go through it, only blocks do. So, when the doom-spire falls, it goes through the ground, but users dont and you have to kill them off, or the ground can just kill them if they touch it in certain places. I don't know how to do that though. Can anyone help me?
