[Pyode-user] Adjusting mass

[Joseph Q. <cpu...@gm...>]

Hi,
I'm working on a space game (kind of like asteroids) but I'd like to
be able to adjust the mass of the ship. I can't, for the life of me,
figure out how.

My code sets the properties for a ship with:
def Ship(self, mass, pos, ship):
		M = ode.Mass()
		M.setSphere(mass, 0.05)
		ship.setMass(M)
		ship.setPosition(pos)

But how do I go back later, and adjust the mass? I've tried (using Pygame):
elif e.key == K_d:
	#self.Ship(mass, position, ode.Body)
	M = ode.Mass()
        M.setSphere(2500, 0.05)
	M.adjust(100)
	print M
    	playerShip.setMass(M)
	print playerShip.getMass(M)

Yet this does nothing, (as far as I know) to the existing ship (it's
velocity doesn't change). Am I creating a new Mass for the object
instead of modifying an existing one?
Thanks,
Joe
