You should refer to the advanced ability tutorial written by @jedk1So, I'm fairly new to this, but I was looking for some help as to how to make blocks appear and disappear, such as the Torrent Wall move that pushes entities away for Waterbending. I'm trying to create a move called WaterExplosion, which is supposed to kinda of create a wall almost like the same move, but cause damage and have a slightly different animation and speed. Anyway you could help?
