I have a game modified off of the simple Vertical Space Shooter template. The 'enemy' sprites are generated every second, and I have a animation frame of 26 images, for which I assign one at random when the new sprite is created. (Each sprite represents an object starting with one of the letters of the alphabet).
I have another sprite that moves around to collect these items, and collision detection seems to work fine... except
there appear to be sprites generated which don't appear visually but do trigger the collision detection. I captured some of the properties to the screen in other fields and they look like legitimate objects, they just aren't displaying (as if opacity were 0 - but it's not).
I even see one triggered way before it's logically even generated - since I have a 8 second delay (for reading a message screen) before I start the object generation, but a collision is detected pretty much as soon as the layout starts.
Any ideas on how to track this down?
