Locking a framerate
Author
What is a good way to lock in a framerate for a program so that it will run at a consistent speed despite the hardware it''s on?
Or is there a better way to handle this type of problem? Thanks!
Please be as specific as possible... i''m fairly green at this DX stuff...

a better way is to not lock it. do a search on the forums. this question has been asked a million times and doesn''t need to go in depth here.

This would quickly become a very boring site if all we did was search forums...
You need three variables:
int m_iLastTime
int m_iThisTime and
int m_iTimePassed;
At the begining of your gameloop do this:
That way m_iTimePassed will contain the number of elapsed milliseconds since your last gamepoll.
If you want to move an object (like a spaceship) 50 pixels per. second then do this (this example uses floats):
Oh..One last thing...Before you start your gameloop for the first time you should do this:
Hope this helps you and that there are no errors...

m_fSpaceShipPosX += 50.0 * ((float)m_iTimePassed /1000.0); Oh..One last thing...Before you start your gameloop for the first time you should do this:
m_iThisTime = timeGetTime(); Hope this helps you and that there are no errors...

Thanks both of you all... and granat, i agree 
And for the record, i did do a search, but didn''t find anything as straightforward as i wanted, thus this post came into existence (maybe now someone in the future will find what they are looking for).

I agree completely. but why post redundant topics when the same question has been asked and answered within the past 5 days?
I searched frame rates in the past 5 days and got a nice handy link to a thread called "Frame rates" (which btw discusses this)
just a thought.

Isn''t that post about measuring framerate, not handling it?

I never have much success with the search function..
Sometimes it finds 2 billion topics and sometimes it finds nothing...

I don''t completely remember. that''s not the point though. the point is that you can search the forumns. anyways, I don''t want to start a flame war over a trivial topic.
cheers,

neither should you, you freaking hippy! 
Honestly, though yeah posting helps, if you read my other post..(this is what I kinda said):
"Just writing out the question can help clarify and help you find a solution.."
