Also on the subject of speedometers, please either put them in m/s or make us able to set it to that. I play a lot of PS2, and one of the things I hate most is that the speedometers are in km/h, so I have to mentally multiply that number by 3.6 to get my speed in useful units.

Yes absolutely. I agree--I didn't even know it was moving backwards with the numbers. It would have been more obvious if I turned right and suddenly I'm facing West. I'm pretty sure the artists, when they update the texture for this, will add some markers, but I can't say for sure.

As for displaying objectives and such on the compass (an earlier question asked this). This is a little more complicated than the compass itself, as the position is related to the objective position and your position/orientation. Actually, when I first thought about it, I thought this was hard, but then after a day I realized it isn't. You just need a normalized vector to the objective and the players facing vector--then you can figure out the angle (same way with the compass--arctan2). This could actually be done with a shader, but you would need texture sampler for each objective. Also you could create a different polygon ring for each objective and let them sit slightly on top (so close you couldn't tell). The hardest part is getting the position of the objective--this wouldn't be immediately available in the shader, but it could be set with an event, as objectives don't change position (but if we wanted to track other things that do change position that may need to use a different way).
Wow--this is cool--totally do-able. Thanks for making me think about it. I'll propose it to the team.
