Joystick Effect

I am looking for a way to do a smooth control joystick effect. I was thinking that if worse came to worse, I could have a small cube (the controller) inside of a big cube (barrier) that could be moved around with ctrl-grab to simulate a joystick effect, but I am looking for a way that I could smoothly move the handle of a joystick around.

Thanks,

Well with the implementation of Mono, I reccomend you use the llDetectedTouch functions.


Here's how I would do it:

Joystick prim(child prim)
"Cover" prim(A transparent cube that sits above the joystick)

The object would not be physical.


When a touch is detected on the cover prim, the script uses the llDetectedTouch functions to work out the local position of the touch. It then relays this information to the joystick prim, which moves accordingly.



Let me know if I'm not making any sense

Cover prim would ideally be a sphere as well.. Another way would be to use llDetectedGrab and doing some very simple maths.

Both methods have advantages and disadvantages

Using mono touch would be easy enough to implement by offsetting the input you could directly use that as output.

llDetectedGrab would prevent someone falling off the cover prim and from ultimately losing control. But would require some maths to implement it.

Hmm... that's a good idea right there. Do you know if there is any way that I could move it smoothly like a joystick and from side to side quickly, or is the way you said going to do that?

It should work like that if the event is "touch" and not "touch_start" or "touch_end."
