Question

Hey so i have a sprite class, and i am making it turn 360 degrees a second, while increasing speed at the same time. However I end up spiraling and not staying on the original circle formed by the continuous turning of 360 degrees per second.

How can i fix this? The sprite needs to go faster and stay on the same path.

here’s the code:

box.Accelerate(10*Window.GetFrameTime());
box.Turn(360.0*Window.GetFrameTime());

Answer 1

If you want to make a sprite go in a circle, put that in the code. For example,

float time = Window.GetFrameTime();
angle += speed * (time - lastTime);
lastTime = time;
float x = sinf(angle), y = cosf(angle);
box.SetPos(50*x + center.x, 50*y + center.y);
box.Turn(angle + QUARTER_TURN);
