It would be great if you could decorate a screen, similar to how the colour-coded-tilemap extension works. That way sprites can leave the screen, and you can have them destroy themselves.
When using a tile map in this game, there are four sprites where sprites 1, 3, 4 can overlap (i.e kill the player) and sprite 2. cannot.
Top to bottom
- can overlap, but cannot leave screen.
- is a ghost, so it does not overlap, but CAN leave the screen
- is set destroy outside screen, but stays there until the player moves left
- can overlap, but when it destroys itself, it is within the boundaries of the game.
It is not a big deal, but you might notice that the ghost sprite leaves outside the game, while the bottom sprite leaves within the game.
For a tile map, I would be great if a sprite, that is set to ‘auto destroy’ itself (i.e. outside the realm of the screen), that might occur when it hits the boundary of the tile map. I understand when @jwunderl mentions in Enemy Defeat how this works.
