Allegro: RAM fährt bis auf 2 GB

[ZeroConfig]

Hallo,
also ich habe mich seit Gestern von der Konsole verabschiedet und verwende Allegro.
Als ich meiner Terrain Sidescrolling verpasst habe und ich compilierte,
fuhr mein RAM bis auf 100%.

Da ich in Sachen Bitmaps & co noch neu bin weiss ich nicht, was der Fehler sein könnte.

Wäre für jede Hilfe dankbar!

MfG Zero

du erstellst in der while schleife jedes mal das bitmap terrain, gibst aber nur einmal am ende des programms ein terrain frei.

[ZeroConfig]

Hast recht, habs verbessert aber hat leider nicht viel gebracht...
EDIT: da stimmte was mit der Funktion Bridge was nicht... gleicher Fehler, ausgebessert!

THX an alle!

[otze]

in der funktion bridge haste dasselbe Problem

[ZeroConfig]

Thx nochmal!!!
Hoffentlich werd ich mal mit meinen Game fertig....
