I want setHPR relative

Scripting Issues
1

I have a game with a steerable torpedo, and the camera follows the torpedo. Steering is done with the arrow keys. But now when i have steered a little with right, and then i steer with for instance down, the torpedo rotates around the main x,z,and y axes of the game, but i want the axes of the torpedo steer together with it. so they should be relative. How is this possible?

This:

yourNP.setHpr(otherNP, 1, 2, 3)

will rotate yourNP relative to otherNP. You can also rotate it relative to itself:

yourNP.setHpr(yourNP, 1, 2, 3)
