That didn't take too long. I completed the coding of Cannon I. Something I didn't post in my previous XNA Xtreme post are the specs of the game. Pretty simple:
Simple shooter game where the player shoots one target at a time;
The player can't win the game (no goals or targets);
Player is controlled with the mouse;
Target comes down at a random angle;
Each time a target is hit, the following target comes down faster;
When the target touches the ground, player looses one life;
When all lives are lost - Game Over;
Finally, only one projectile can be shot at a time.
Simple enough? Next step is Cannon II where we take the same game to the "Engine" and OO Programming world.
