time based movement and WinAPI + DirectX

[chronozphere]

what is better? DeltaTime(FrameTime) or timer with fixed interval?

You could do that, but i do think it has any advantages. You are running away from the actual problem, instead of solving it (check my sig Very ). I think it is better to make a decision. Use time-based movement with OnIdle and DeltaTime or FrameTime, or use a timer with a fixed interval. I would choose the first one.

It is little harder to implement, but it is rewarding in the end. Wink

I think that frame-based movement is better than using a timer. For example when you are running the app on a realy slow PC, and you set your timer to 60 FPS, the PC might not handle that speed. The result is that your app runs slower than you want. This is not the case when using Frame-based movement.

Offcourse, if you want to use a timer, i'm not gonna stop you. I only think that frame-based movement is more elegant.

Hope it helps.

A good timer will have same result on a slow pc
