Damn I'm so frustrated I'm so busy with university and work. I could easily do that in 3 days tops; I already have some basics for that.
If I may however, this... I'm not sure this is good for the community. I mean normally this is something we could do for each other for free. Or at least help each other with it. Now instead of just helping a person in need with info or code we are tempted to make a script and sell it instead.
I'm an idealist. I hope this won't make the community greedy and selfish

(that said, PM me about that request and I'll tell you how it's done for free. I don't have it done yet, but I played with something similar to that and it worked nicely)
On the other hand.... since we're posting requests here, this is what I would pay for from my tiny part time job money:
A complete working PLAYER class. What esenthel provides is nice, BUT it lacks a lot of basics things like:
- fall damage
- swimming (on surface and underwater)
- smooth customizable animation container for character (let us easily add an use animations for things like hits, jumps, idle, swim, etc)
- removing glitches (such as when running up a ramp and then jump like a nascar car high in the sky with your character)
I do have my improvised solutions for all of these, but this is something I'd like to be done by a pro, because it's the part of the game that will be executed 95% of the time and it's very important to be done properly and efficiently.
