Game Object: worldOrientation

worldOrientation
  • Get/set the object's world orientation

Type:
  • float list 3x3 matrix
3x3 matrix:
  • [ X-axis vector, Y-axis vector, Z-axis vector ]

X-axis vector:
  • [ cosine of the angle of the world X-axis to the game object x-axis,
      cosine of the angle of the world X-axis to the game object y-axis,
      cosine of the angle of the world X-axis to the game object z-axis ]
Y-axis vector:
  • [ cosine of the angle of the world Y-axis to the game object x-axis,
      cosine of the angle of the world Y-axis to the game object y-axis,
      cosine of the angle of the world Y-axis to the game object z-axis ]
Z-axis vector:
  • [ cosine of the angle of the world Z-axis to the game object x-axis,
      cosine of the angle of the world Z-axis to the game object y-axis,
      cosine of the angle of the world Z-axis to the game object z-axis ]
Example:
  • Game object axis orientation is the same as the world axis
Values:
  • Cosine of 90 degrees is 0.00
     
  • Cosine of 0 degrees is 1.00
World X-axis:
  • angle to game object x-axis = 0 degrees
     
  • angle to game object y-axis = 90 degrees
     
  • angle to game object z-axis = 90 degrees
World Y-axis:
  • angle to game object x-axis = 90 degrees
     
  • angle to game object y-axis = 0 degrees
     
  • angle to game object z-axis = 90 degrees
World Z-axis:
  • angle to game object x-axis = 90 degrees
     
  • angle to game object y-axis = 90 degrees
     
  • angle to game object z-axis = 0 degrees
3x3 Matrix:
  • [[1.0, 0.0, 0.0], [0.0, 1.0, 0.0], [0.0, 0.0, 1.0]]

Example:
  • Game object is rotated 45 degrees on the game object y-axis
Values:
  • Cosine of 90 degrees is 0.00
     
  • Cosine of 0 degrees is 1.00
     
  • Cosine of 45 degrees is 0.7071
     
  • Cosine of 135 degrees is -0.7071
     
World X-axis:
  • angle to game object x-axis = 45 degrees
     
  • angle to game object y-axis = 90 degrees
     
  • angle to game objcet z-axis = 45 degrees
World Y-axis:
  • angle to game object x-axis = 90 degrees
     
  • angle to game object y-axis = 0 degrees
     
  • angle to game object z-axis = 90 degrees
World Z-axis:
  • angle to game object x-axis = 135 degrees
     
  • angle to game object y-axis = 90 degrees
     
  • angle to game object z-axis = 45 degrees
3x3 Matrix:
  • [[0.7071, 0.0, 0.7071], [0.0, 1.0, 0.0], [-0.7071, 0.0, 0.7071]]
Sample Code

################## get the game object's world orientation

# import bge
import bge

# get controller
cont = bge.logic.getCurrentController()

# get object that controller is attached to
obj = cont.owner

# get the world orientation
orientWorld = obj.worldOrientation

Sample Code

################## set the game object's world orientation

# import bge
import bge

# get controller
cont = bge.logic.getCurrentController()

# get object that controller is attached to
obj = cont.owner

# set the game object's orientation same as world axis
obj.worldOrientation = ([1.0, 0.0, 0.0], [ 0.0, 1.0, 0.0], [0.0, 0.0, 1.0])
