My updated version of the game template uses collisions with Any Actor to specify what is solid. Actors that are solid have a variable (solid=1) at creation. The player collides with any actor constantly during frame rate, but colliding with an actor with a solid attribute would result in a physical response.
Now the problem is specifying collisions with Any Actor with enemies, or, particularity, anything out of view. It occurs that, when the collisions with Any Actor are specified to anything out of vision, the game just crashes upon startup (game mode). Well, sometimes it does, sometimes it doesn't, which makes me totally bewildered.
Would this mean that using Any Actor to specify what is solid is useless and obsolete? Using Any Actor saves loads of time and keeps it to simplicity. ...So I'm seeking help from one who is more knowledgeable with the core of game editor. Maybe this could solve and improve everything (and improve for those who use the template).
