I removed loader class vars and implimented changes as you suggested:
var obj1:Object3DLoader = Obj.load("assetts/teapot_1.obj", ... all is
good there.
I had thought late last night to use the Object3D instead of the
loaders
obj2object3d.visible=false;
obj3object3d.visible=false;
obj1object3d.visible=true;
etc,etc.... tried it, still not work ...
Just changed button handler and added some tracing:
private function txtButMouseDown(event:MouseEvent):void
{
if(objtoload == 3){objtoload=0}
objtoload+=1;
trace("objtoload "+objtoload)
if (objtoload==1){
trace("objtoload load 1");
obj2object3d.visible=false;
obj3object3d.visible=false;
obj1object3d.visible=true;}
if (objtoload==2){
trace("objtoload load 2");
obj3object3d.visible=false;
obj1object3d.visible=false;
obj2object3d.visible=true;}
if (objtoload==3){
trace("objtoload load 3");
obj2object3d.visible=false;
obj1object3d.visible=false;
obj3object3d.visible=true;}
trace("obj1object3d state="+obj1object3d.visible)
trace("obj2object3d state="+obj2object3d.visible)
trace("obj3object3d state="+obj3object3d.visible)
}
trace on button presses give:
"1st press"
objtoload 1
objtoload load 1
obj1object3d state=true
obj2object3d state=true
obj3object3d state=true
"2nd press"
objtoload 2
objtoload load 2
obj1object3d state=true
obj2object3d state=true
obj3object3d state=true
"3rd press"
objtoload 3
objtoload load 3
obj1object3d state=true
obj2object3d state=true
obj3object3d state=true
... all 3 objects are displayed on screen all the time and visibility
state remains TRUE for all ... ugh :S
I really am trying to get this on my own and trying to avoid bothering
people ...
