How to simulate AV movement by control

How can the AV movement be simulated exactly via llTakeControls -> control?
In detail:
a) I want to modify standard jump height while maintaining automatic jump animation.
b) I want to modify standard walk and run speeds.
Would make me happy to get useful response *smiles*
Thanks in advance, Tomo

llMoveToTarget would be my choice, with a high tau value (that you would modify to speed up or slow down the movement)... if we're talking strictly NPV based... the animas can be triggered as you like, although getting accurate falling with directional movement might be difficult

Just a quick addendum to my first post:
I don't want to waste ugly much time by re-inventing the wheel, I am RL-professional software architect, not interested in playing with LSL, but rather get a customizable feature base - so hints for experiments do NOT help.
A full open source script, which maps standard behavior exactly to scripted behavior SHOULD exist, but how and where to find?
Thanks in advance *waves smiling*

Try XStreetSL or try posting in the Products Wanted or Services Wanted forums. You'll have better luck there. This is the place to come if you want to share a neat scripting idea or problem, or if you need help figuring out how to script something in LSL yourself.

the only real references are the wiki's, and the various pages for each item. there MAY be a separate one that maps those functions working together, but I'm not aware of it. I agree it'd be handy to have, unfortunately lsl documentation is 99.99% user generated... after the fact, and only through experimentation. professionally it's a nightmare of the worst order.

if you're lucky someone may come along and drop something like that here, but it's doubtful. alternatively you could could ask in services wanted for someone to whip up a quick Non-Physical Vehicle script with move to target and animation triggering mapped to standard movements.

the relevant wiki pages can be found at the following addresses, which also contain links at page bottom to an alternative source in most cases. They MAY be enough of what you need, if not I'd try the other suggestion.

Once you give up looking for an existing one, which I'm fairly sure does not exist, and write it yourself, please make the source public so we know what to tell the next person who asks.
