I am attempting to create an in-game projectile that moves on a grid at a certain translation per second, but to do this I need equations to find the translation of the projectile in the two orthogonal directions using the angle of motion and the distance per second (speed).

CodePudding user response：

Break the speed u into ux and uy using trigonometry.

S  = U * time;
Sx = S * cos ( theta )
Sy = S * sin ( theta )
