Why? Very simple, the situation is as follows: I have a boss arena and 4 monsters with certain specials and attributes as well as tags are placed outside this boss arena. When the players (yes, coop!) enter the sector, these bosses were moved/spawned in this boss arena. As soon as all of them are dead, the map quits.
Now I have the problem that if a player is standing on the mapspot of one of those 4 moving spots for the boss monsters, the boss monster doesn't get moved, the players can't kill each of them and the map can't be exited.
Now with the "Thing_MoveForced" and "Thing_Spawn(Facing)Forced" specials (or maybe another argument?) the scripts try to move or spawn a specific actor until it gets moved or spawned in the end in case some object is blocking the spawn spot.
You know what I mean?! I'm sure you do
