Increase at same rate with FPS drop.

[izac]

Hi,

What we be the correct mathimatical equasion to increase an Alterable Value by 1 every 1 second, so a game at 50fps would count to 50 every 1 second, but if the FPS were to drop below 50, how would I ensure that the Alterable Value still counted to 50 every second even below 50fps.

Thanks.

Edit: This is also similar to how the in-built movements make up movement speed when the FPS drops.

You could do it in a almost correct way like this:

+always
-add (1.0/frame rate)

But to get true precision you'd have to implement frame rate interdependency see this article

Hmm interesting, I had a little think about this, and wouldn't:

1 * [setframerate] / currentframerate

^ so a game programmed to run at 55fps running at 55fps would look like this:

1 * 55 / 55 = 1

^ and a game meant to be running at 55 but runing at 23 would look like this:

1 * 55 / 23 = 2.39

-

I guess this would work right? it might not be 100% accurate, but it'd be better than assuming the game will run at 55fps on all machines - and I also assume it would only work with alterable values as they have decimal points.

Thanks

Yes, exactly.

EDIT: Though normally you change to using "per second" instead of "per frame" numbers:
So instead of:
Always:
-Add [change per frame] * [desired framerate] / [frame rate]
You just do:
Always:
-Add [change per second] / [frame rate]

But what you put is a good drop-in replacement to code which currently says:
Always:
-Add [change per frame]
