I'm working with Sprites and using "pickSprite" and "pickedSprite" in this code:
spriteManager.isPickable = true;
player.isPickable = true;
var pickResult = scene.pickSprite(event.clientX, event.clientY);
pickResult.pickedSprite.cellIndex = 1;
It's part of a program with a crawling bug you have to hit with a mouse click. But there is no hit possible. Only if the bug doesn't move I can hit it with the mouse.
