Ok, new problems. I've attached a forklift I am creating, i am trying to make the vehicle move using controlled hinges because I want it to move forwards and backwards. My problem is, that whenever I try to adjust a setting that SP apparently does not like (example - rename servo6149 to servoarm2) it doesn't apply my changes and the next time I click on the UI button, nothing comes up, no matter what part of my model I have selected. The only thing I have found to fix it is close the program and restart it.
Any clues on how to avoid this?

Also, is there a list of controllers available for SP3? I know of slider('x') and key('x'), are there any others, or even better, a document listing them?

Thanks,
Mez

Hi, I am having a bit of trouble controlling joints using keys. I have made a car with wheels that spin when the slider bar is dragged to 1 and a steering arm that rotates with a separate slider bar.
My problem is, when I set the controls to keys and run the simulation, the steering axle locks to the left and the wheels beginning spinning in crazy directions. Can I not bind a key to the same operation as a slider? For example, X = accelerate, A = rotate steering arm left, D = rotate steering arm right.

Thanks,
