Title: Timer Class
Post by: kryton9 on June 26, 2011, 10:10:58 PM

Updated:

Here is the latest Timer Class for review? I am not sure whether FPS needs to be in this or not as FPS doesn't need high res timer, so I am thinking of making that a separate class.
Unzip it into OxygenBasic. It will add into the inc folder  a go2 subfolder with the inc files.
It will also add to the project folder a TimerCTest folder with the test program inside.

Thanks Kent,

This affinity stuff is new to me. I think it is quite easy to measure lapsed time in microseconds with QueryPerformanceCounter. . WM_TIMER messages are hopelessly inaccurate, and only fit for counting seconds.

We need to probably make a thread class too. Once we get the timer class working we can then make the thread class.  All of the high end gaming development kits use threads, one for rendering, input, sound... etc. I think I read somewhere that UDK (the Unreal Development Kit) runs 8 of them in parallel.

I've done some work on multithreading already. String memory management including garbage collection is the major issue.

Just update Oxygen (in-progress)

Thanks Kent,

I am working on the thread side. Then we can have timers running in the background, making callbacks etc
