llSetLocalRot

void llSetLocalRot(rotation Rotation)

Sets the rotation of a child prim relative to the root prim.

Parameters

Rotation (rotation)

Technical Details

Return Type: void
Energy: 10
Sleep: 0.2s

Drop this script into a child prim to rotate it in 1 degree increments on each touch:

rotation rot_xyzs;

default
{
    state_entry()
    {
        vector xyz_angles = <0,1.0,0>; // This defines a 1 degree change on the Y axis
        vector angles_in_radians = xyz_angles*DEG_TO_RAD; // Change to radians
        rot_xyzs = llEuler2Rot(angles_in_radians); // Convert to a rotation
    }

    touch_start(integer s)
    {
        llSetLocalRot(llGetLocalRot()*rot_xyzs); // Apply the increment rotation to the prim's current rotation
    }
}

Alternative Approach

This is an equivalent call from any prim in the same link set:

//-- where "target_prim" is the link number of the prim you want to set the local rotation of
llSetLinkPrimitiveParamsFast( target_prim, [PRIM_ROT_LOCAL, rot] );
