   PGU Tiles collision detection
  Hi, I've been using PGU(Phil's Pygame Utilities) for a while. It has a dictionary called tdata, which is passed as an argument while loading tilestdata = { tileno:(agroup, hit_handler, config)}I'm making a pacman clone in which I have 2 groups : player and ghost, for which I want to collision detection with the same type of tile.For example, if the tile no is 2, I want this tile to have agroups as both player and ghost. I tried doing the following:tdata = {0x02 :('player', tile_hit_1, config), 0x02 : ('ghost', tile_hit_2, config)}However, on doing this, it only gives collision detection for ghost, not the player.Any ideas on how I can do collision detection for both the player and the ghost with the same type of tile?
