I learned from game class that in update function, every movements must be time dependent for the sake of linearity in movement.

We made a simple game. Every move like going left, right or jump is written time dependent.

But, in some other computers, our game is worked very differently. For example, our character jumps higher than it should be. I guess this is because each computer has different FPS rate according to its specification.

My question is that what should we do to make this game work in same way in every computer? Setting FPS rate to a constant is a solution?
