Moving a projectile from an angle.

Felipe Müller · 2012-11-10T22:20:15

Hi, I'm trying to make something like a game... where I have a sort of a cannon that shoots projectiles, and this cannon is constantly rotating around itself, and around a point in the center of the screen. And it's 2D Well, I have a bullets vector, that I can get the X an Y position of them. When I create every bullet I create them in the cannon X and Y position, and I also keep the angle that the cannon was in another vector. The question is... how do I move them in that angle? I do not want to use gravity or anything like that, just move them in a constant velocity in the direction of the angle I have. I'm using SFML, and I'm using sf::Shapes for all. So to move the projectiles, I can either use the Move() function, that has X and Y parameters and move the sf::Shape with the value that I put on the parameters, or I can use SetPosition(), that also has X and Y values.

I have an idea what complex numbers are, and I know there are some great videos on youtube about this, I actually watched some, but I don't remember anything about it now. I know they'll be there for when I want to learn =)

I'm not in college anymore, I'm 21. I'm 100% sure they didn't teach that. =|

There is a guy at my work that told her daughter he would pay for her college education if and only if she took Linear Algebra and Statistics. Smart man...
