llRezObject Projectile Rotation Issue

[Zoraster Lunardi]

I am rezzing a projectile with the llRezObject function and the projectile launches as expected. I can move the object and the projectile rez follows the objects as desired,

 But I can not figure out how to rotate the object and have the projectile launch in the direction of the launching object.

The third parameter - vector vel - is the direction in which the rezzed-object will move.  If you give this a fixed value the projectile will always launch in that one direction.  You must therefore rotate that direction to match the parent object.  To do that multiply by the parent's rotation:  <vector> * llGetRot()

Thanks for the tip. My project is working as planned now.
