Hey guys, have a problem that i have been trying to solve on my own for quite some time now, still can’t do it : /

i need to add a camera that can track my car as you drive it around… hope you can help me add one.

I just need help adding it properly , i can work out the tracking myself, if you don’t have some spaced out way to do it…

i know there are some minor glitches, or maybe some bigger ones, i’ll work it out later, the modeling isn’t all done yet either, so no need to tell me^^

the file is far too big to add the source… so i’ll post the code right here. Let me know if you want the source, i can mail it to you.

k, here goes.
