AW: Bestimmte bereiche einer fla laden und den rest im hintergrund. geht das ?
hmm ich da ne schwierigkeit ....
das mit dem wasserfall hat super geklapt, nur warum werden alle objekte die ich vor dem wasserfall platziere (überschwämmt) :'( ?
ich wollte nämlich am fuße des wasserfalls nochmal eine kleine nebelbank platzieren, damit man die gerade kannte nicht sieht.
Aber jeder versuch ist gescheitert. Jemand ne idee warum das so ist ?
- Z-Ebenen stimmen, hab die in beide richtungen ausprobiert.
hier al der code vom wasserfall
