Alright so I reupdated the software now. It utilizes a good mouselook system that keeps the code to a minimum. The original script was copied off of the on in jedis 'FPS System' notable new features include:
A better HUD, since I started this entirely from scratch, I redid the HUD design too. HUD works just like it does in the Halo on 360, there are a few bugs, I'm still trying to pinpoint what they are though, or why they are happening. Top bar is your sheilds. Rectangles are your health. Press ENTER to damage yourself. Wait 3 seconds and than your sheilds will charge. The topright text is your total ammo, below that is clip ammo. You can't shoot yet.
There is an idle animation, it is always consistantly playing even when you move because I'm still working on that part of it. There is a new more Halo-Like redicule. I plan to have it expand as part of the kickback so tell me if it's too big right now. It's recommended that in the real game you play on fullscreen (windows as big as possble, clicking outside the window does not activate mouse clicking.
The assualt rifle is from the acuall halo and displays ammo on it as well. Plus there are spartan hands and the death will include 3rd person zooming.
WSAD to move and C to toggle the mouse look on and off. This way you can rearange your mouse. Please feel free to take the models as they are not mine to begin with, the spartan and assualt rifle are debussybunnys so credit to him

You can't take my healthbar though, and if your interested in how I did the acuall health of the healthbar, I just had 3D text with the bottom font and the text changes in the drawHUD method.
Anyways enjoy!
