Rotation problems

[Slaine]

Hi I'm having a few issues with rotations, it seems when I rotate on the pitch it gets to a certain angle, say 180 and then it bounces back 180 then forward again, I have from what I can tell solved it partially with this code.

Code: Select all

ePitch = pxBodyGetRotationPitch (sphereBody)
	eYaw = pxBodyGetRotationYaw (sphereBody)
	eRoll = pxBodyGetRotationRoll (sphereBody)
	
	If eYaw =-180 And eRoll=180
      	ePitch = 180 - ePitch 
   	EndIf

	If eYaw =180 And eRoll=-180
      	ePitch = -180 - ePitch 
   	EndIf

sphere_node.setRotation (_VECTOR3DF (ePitch, eYaw, eRoll))

I'm using Agia PhysX so thats that function.
But, this only solves the ball rotating on it's pitch and yaw, as soon as I mix a pitch and roll angle, the ball rotates very erratically, almost like it keeps wanting to re-set to 0.0 after every 90 degree.

take a look to this topic and the use about quaternions
