Can't achieve framerate independent movement
Hello,
I can't get my movement to be framerate independent. Here's the code I using inside Update:
void Update ()
{
if (Input.GetKeyDown(KeyCode.Escape))
Application.Quit();
if (Input.anyKey)
{
velx ++;
}
else
{
velx *= drag;
}
velx = Mathf.Clamp(velx, -max_velx, max_velx);
Vector3 delta = new Vector3(velx * Time.deltaTime, 0, 0);
transform.Translate(delta);
}
When I change the quality of the graphics in the game.. the player speed changes considirably. I can't see where the problem might come from, since I'm scaling the velocity by the time spent on the frame.
yes, but velx gets changed by constants and not by deltaTimed values. velx++ and velx *= drag are called as often as Update is ran.
OOO$$anonymous$$..thanks. I understand. But isn't there a way to cap the calling frequency of the Update method? I'm planning to run my game at 60FPS..And I don't care if the user's machine can't do that(he should buy another machine or lower the settings). I'm using velx++ ins$$anonymous$$d of velx+=Time.deltaTime is I don't want my movement equation to be quadratic in terms of time.. I think that's non intuitive when it comes to gameplay tweeking.. What do you think?
Use FixedUpdate for a fixed call interval ins$$anonymous$$d. What you mean with quadratic equation, I don't know.
If you do velx+=Time.deltaTime and then you do Translate(new Vector3(velx*Time.deltaTime,0,0)) now your position depends on Time.deltaTime².. this is what I mean by quadratic in terms of time.
I used FixedUpdate but I got some weird input, and the player wasn't responding as he should.
