And if I can add to that concept you can also base that speed on the
amount of time elapsed since the last frame.
That way if you are holding forward you move at the same speed
regardless of whether you are getting 30, 60, or 100 frames per second.
So for example:
float distanceTravelledThisFrame = secondsElapsedSinceLastFrame *
playerSpeedConstant;
Some very old dos games had speed problems when run on a faster computer
because they were updating your position based on how many times the
processing loop ran in a second rather than how much actual time had
elapsed.
You may remember games like Space Quest that had a speed setting so you
could adjust this to be reasonable for your computer.
But they didn't have enough settings to keep up with the rapid speed
improvements of computers, smile.

Hi Cara,
I haven't pondered this. Are you saying, for example, that you could give
the player a forward velocity of 0.1, and as long as walking is true, update
that every time through the game loop? Then if the velocity is 0, he just
wouldn't move?
Fascinating concept. I wouldn't mind some clarification.
All the best,
Ryan

Hey there y'all,
Maybe I'm missing something here, but rather than using a timer at all,
would it not be more appropriate to simply calculate a velocity vector each
frame which could either stay static or change depending on the player's
surroundings. This way the player's movement could be calculated and
performed every frame. No timer necessary.
thanks for the great thread!
Smiles,
Cara :)
