I'm working on this project for about 2 weeks now i first used the
collisionExample.fla but if i needed to adjust the map i couldnt get
it working properly.
My class uses a simple bitmap and checks for the color.
The calculations are the same as in the collisionExample.fla but
instead of checking the collision of the camera i'm checking the
collision of the dot on the map :).
If there is a collision i dispatch a custom event and reset the camera/
cone/2d player to the old position.
You can find the UserMap and CollisionEvent classes here :http://
labs.speak.nl/3d/away3d/demo14/src/collision.rar
It's used like this:
//CREATE MAP
var userMap:UserMap = new UserMap(yourmapbitmapdata);
this.addChild(userMap);
userMap.addEventListener(CollisionEvent.COLLISION,onCollision,false,
0,true);
//RENDER ON ENTERFRAME
private var render(event:Event):void{
var xpos:Number = (camera.x / (envWidth / userMap.width)) +
userMap.width / 2;
var ypos:Number = -(camera.z / (envHeight / userMap.height)) +
userMap.height / 2;
var playerPoint:Point = new Point(xpos, ypos);
userMap.position = playerPoint
}
//COLLISION
private function onCollision(event:CollisionEvent):void {
trace("collision")
}
