2D Tank Game.

Xtez (1)
Hello, I am looking to make a type of tank game in C++, The main idea of the game is simple, kill the enemy using the angles you input in the program. For example, if the enemy is placed at the distance of 42, you put in the angle for your bullet to shoot at the opponent and it calculates wherever you hit or missed the opponent.
I got some equations that helps and i included it in my program but I need that tiny push to do 2 things in my code.

1. I need to make an enemy and make him big enough for me to hit him rather than just 1 co-ordinate,

2. I need the formula to actually shoot at the enemy, It needs to include gravity and have a motion to shoot.

Thank you.
