Do you have a GUI mockup?

If you create a task in the Windows Task Scheduler, it will turn on your PC. I had a pesky backup program that kept turning my PC on every day at 5pm to perform a backup :(

Excellent!  Nothing better than the feeling one gets after solving a brain-buster.

Now that you have the thing working (grin) it's time to rip it all out and replace it with this:

I've found that performance can be enhanced greatly in these kinds of games by precalculating all the SIN/COS values for each possible direction of movement and storing them in lookup tables.  RAM is cheap, the data we're talking about is not huge (assuming something like 5 or 10-degree increments), and the performance improvements can be breathtaking.  Integer lookups are nearly instantaneous, unlike SIN/COS calculations.

And yes, my motto really is "fix it even if it's not broken".  :-)

I'm writing a simple driving game, no proper physics or anything, so performance isn't really an issue :p

And whatever you posted, I can't see it  :P

After hours and hours of swearing at the screen, poring over numerous tutorials and source files, I finally got it to work. Using degrees instead of radians was one problem, but also rotating around the wrong origin was the main issue.

Distance is the amount in pixels it should travel.


I can move the vehicle about in any direction I want, but calculating how far X and how far Y to travel based on the rotation is the bit I'm struggling with.
