Hi!Whit my friend have started to develop 3d game with away3d for
school topic and we cannot deal with the animations.I am loading two
md2 models- the ogre from the lessons, then in onKeyDown it is
registered where to move in boolean variables , in onKeyUp is
deregistered, and in onEnterFrame this variables are checked in if
forward is true it plays the run animation else play the stand.The
game plays the run animation once and then cannot change to stand.Any
suggestions? onkeyDown and onKeyUp are down, just scroll.Also there
are two extern files for Terrain and Resources,but they are not
related:
