Projectile?

CTank Tank;
Tank.Fire();

Simple as that.

What is your question? I need help isn't a question.

A projectile leaves a gun with some initial velocity. Velocity is a vector. Picture a vector as an arrow: It has a length AND a direction. Read the simple stuff on vectors here in Gamedev's Articles and Resources section.

Each frame, gravity accelerates your projectile downward. It is a constant acceleration. You can do this by adding each frame the vector 'g*(0, -1, 0) * deltaT' to your velocity.

Then, each frame, add your velocity to your position.

The technique of keeping track of velocity and position and adding each frame is called Euler integration. Google for this term.

How would I implement this? One simple way is with a list of bullet objects. Whenever a tank fires, add a bullet to the list. Each frame, also check to see if any bullet has collided with any tank, and perform the appropriate actions (subtracting health points, etc). Each bullet object in the list could have a position and a velocity, both of which are vectors.

I suggest that anyone that doesn''t know how to do this already pick up an introductory physics textbook. You''ll learn a lot.
