In this video I will show you how to make a working collision in macromedia flash 8. Here are the lines of code.... First give an instance name to the wall called w1.... then enter the following code in the character: onClipEvent(load) { speed=7 } onClipEvent(enterFrame) { if(Key.isDown(Key.RIGHT)) { _x+=speed } if(Key.isDown(Key.LEFT)) { _x-=speed } if(Key.isDown(Key.UP)) { _y-=speed } if(Key.isDown(Key.DOWN)) { _y+=speed } myRadians = Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x ...
