alignAxisToVect

alignAxisToVect(vect, axis, fac)

Aligns a Game Object axis to a World vector.

vect:
Type:  float List

Uses the World axis as it's reference.
(World x-axis = [ 1.0, 0.0, 0.0]
 World y-axis = [ 0.0, 1.0, 0.0]
 World z-axis = [ 0.0, 0.0, 1.0] )

axis:
Type:  integer

0 = Game Object x-axis
1 = Game Object y-axis
2 = Game Object z-axis

fac:
Determines the "speed" of the alignment.

Type:  float

Range:  0.0 to 1.0

Sample Code

# get controller
controller = GameLogic.getCurrentController()

# get object that controller is attached to
owner = controller.getOwner()

# align object x-axis to world x-axis
owner.alignAxisToVect([1.0,0.0,0.0], 0, 1.0)

# align object y-axis to world y-axis
owner.alignAxisToVect([0.0,1.0,0.0], 1, 1.0)

# align object z-axis to world z-axis
owner.alignAxisToVect([0.0,0.0,1.0], 2, 1.0)

Note:
While I am aligning the Game object axis to a World axis, you can align the Game Object axis to any vector. 

Note:
The values of the vector are the cosine of the angles.

applyImpulse

applyImpulse( point, impulse)

Applies an impluse to the game object point you choose.

# get object that controller is attached to
owner = controller.getOwner()

# apply impluse to object center 
point = [ 0.0, 0.0, 0.0]

# impulse to be applied to Z axis
impulse = [ 0.0, 0.0, 10.0]

# apply impulse
owner.applyImpulse( point, impulse)
