OK here is the CAPX to download:

This uses just 5 events:
The ball, net, floor and backboard all have physics behaviors. Click on their behaviors and look at the settings. I also created a net guide sprite that is hidden with physics behavior so the ball goes down through the net smoothly.
The catapult or pivot arm is that green box with the star. I made it invisible but you will see it in the layout.
The physics settings are just a formula to determine how far you pull back on the ball and that determines how fast and at what angle the ball is released.
You can increase the IMPULSE if you want the ball to go faster or decrease the ball density in the ball physics settings.
The game automatically resets after 5 seconds when the ball collides with the ground.
That should get you started on your game and looks like a lot of fun. I made 3 baskets out of 10 shots!
NOTE: I did not create this CAPX and it is included with C2 as a catapult example. I just modified it and tweaked the physics to be a basketball shoot game.
Oh god... this system I already have and implemented, my problem is to create a aim that works! It's not the game system, it's just the aim! Its only it. I understand a bit of the system, but I can not imagine how to do the aim based on what I already have, do you understand?
