Timing in a C# Managed DirectX Game

Im currently programming a C# 2d Game Engine in Managed DirectX and I am having some problems with how to do timing. Ok for now I have a class set up for timing (copied from mdxutil.cs) which gives very accurate time. Now my problem is how to use this time. First I have a class called Sprite, with a method Update(double absoluteTime) and each frame I call this method and pass the current time from the timer. Now lets say I want to move the sprite (according to its velocity) 5 times per second, and I want to update the sprites animation every 2 times a second. How would I use the timer to accomplish this. Is my approach right or am I completely off track?

Thanks

You're on the right track. Now you just need to give your sprite class some variables to track when the animations were last updated and when they were last moved. I typically have a "Move" variable that counts down to zero from whatever time I want, so each update will subtracted the elapsed seconds from the Move variable, when that variable is less than or equal to zero, then I move my sprite, reset the variable and repeat.

On a side note, I see that you're working on a 2D game engine for Managed Direct X. Have you considered porting your code to XNA? Just something you might want to take a look at. Microsoft may have made your life just a bit easier with the stuff they are doing with the XNA framework.

I don't want to move to XNA yet although I have checked it out. Thanks for the info though, I used a very similar method before but this just cleared all my doubts.

Thanks again
