Im very new to this game. I am experienced at modelling its just the scripting. Can someone tell me how to make my canopy rotate 90° when i click it.

Thanks, Dave

I like to use llEuler2Rot and llRot2Euler with rotations. It allows you to specify rotation around the x, y, and z axes without having to know anything about quaternions. Use multiples of pi, e.g. PI_BY_TWO, PI, TWO_PI.

Example:
llSetLocalRot(llEuler2Rot(<PI_BY_TWO, 0, 0>;));

That trick also makes it a lot easier to do the rotations in llSitTarget if your seat prim is not at zero rotation.

Before you start messing around with llSetLocalRot, do this:
llSay(0, "Base rotation: "+(string)llRot2Euler(llGetRot()));

Use what it says for your base (closed canopy) rotation. Then you can play with the three axes using euler vectors. Easy!

Just thought Id chime in with a second option. If you're not worried about the actual movement of the prim, just want it to go up/down. You could also use llSetAlpha on a sort of toggle to switch back and forth between an "up" canopy and a "down" canopy, by making one transparent while the other is opaque and vice versa. Old trick, still works.

On a related note: Is there a simple way to rotate a root prim about its local axis versus its world axis? If not, that function goes to the top of my feature request list... I hate dealing with the LSL rotation functions!

In other words, is there a non-physical function equal to llApplyRotationalImpulse()?

Sweet! I just figured it out!
llSetRot(llAxisAngle2Rot(llRot2Left(llGetRot()), PI/12));
