I started coding our new very very simple game.😀 The name of our game is Cannonball. In the game, the cannon screen of 2 different players randomly placed to the right and left is displayed. We try to shoot the other cannon by entering the Angle and Speed values according to the laws of physics. Of course, it's not at the level to be played yet, but I plan to finish it in 1 week.

DONE

Cannon are fired sequentially
Speed and Angle values can be entered manually, and if desired, the Up and Down keys on the keyboard (decreases or increases the Angle values) and the right and left on the keyboard (increases or decreases the Speed values)

VIP

Damage modeling will be done
The winner of the game will be determined and a small animation will be made.
Physics engine will be slightly improved
Code optimization will be done
