How do I get my gun bike to act less squirrely?

[BNG Da BZ Fool]

It's based off the ISDF rock tank ODF. However, although it performs okay it has a tendency to do wheelies when it moves. I set the forward velocity to 75 and the acceleration thrust to 35. Also, it has a tendency to tilt forward on it's front wheel. Can that be adjust to make it sit more level when idle? Here's a screeny of a group of them attacking the enemy. The tread_l is the front wheel and tread_r the rear wheel. Didn't texture it yet as I wanted to see if it would load into the map editor.

I know if you have the 'treads on ice' issue you can just increase the mass.

[TheJamsh]

you can increase the

'Tread_Static_Friction' and 'Friction_Coefficient' entries if you are using pb3 and above... i THINK those are the right entries, just search for friction in the change logs...

use PitchStrafe, PitchRoll, PitchSteer and PitchPitch put them to 0, should remove the wheelies completely.

if you want, put the ODF up, and ill have a look at it. much easier to tinker with it and show you the changes i've made.

This model is being used under 1.2 BTW. I tweaked quite a few ODF settings to make it quicker then the stock rock tank as it's basically a lite assault type. Anyways, here's the tweaked ODF currently in use for my gun bike:

oh its 1.2... not entirely sure then... thought it was for 1.3

best person in that case would be ZA

I'm getting used to the wheelie effect. I also got the bike to drive a bit straighter by jacking the steerfactor to 9, and reducing the forward speed to 45. I also set the yaw thingy to 0.

[TheJamsh]

the 'factor' controls affect AI only.

braccelFactor = 0.5f; // how often the AI brakes
strafeFactor = 1.5f; // how often the AI strafes
steerFactor = 1.5f; // how often the AI steers
omegaFactor = 1.5f; // not entirely sure, think its pitch
velFactor = 0.5f; // how often it moves

i think the code looks for these when deciding how to move the vehicle. not too sure... again, ZA knows his way around these settings best

Actually TJ, they affect both the AI and the player in terms of the units performance. I still need to tweak a few more settings and add a bit more detail like hands with guns and apply a texture. Lengthen the front and rear forks to compensate for the lifting effect of the suspension thingy ingame. A small group of them can easily take out units like Walkers and Maulers with the twin chain gun turret that the upper part of the body uses. Here's another image rendered out of TS 7.6.
