- Hi,
-
- I'm working on an annimation application. In the main content view
- of my scenario window I want to have several cast members that move
- arround the screen. I need to detect collisions between these actors.
- I wonder if the best solution would be to draw each of them on an independent
- subview of the main content part of my window?
- If this is so, could someone tell me if:
-
- [1] MacApp makes it possible to change from the program
- the relative position of a view from its superView using?
-
- [2] Can I detect from my program if two views are just about to start
- overlapping (they share an edge or a corner)?
-
- My application is very similar to a video-game. When you shoot a
- space invader the program must somehow detect if the bullet has hit the
- martian. How would the authors of "Space Invaders" have implemented this
- feature using MacApp?
-
- Thanks in advance,
-
- Paul.
