Physics Constraints 6 DOF Linear Spring: getConstraintId

getConstraintId()
  • Returns the constraint ID.

  • Returns 0 if there isn't a constraint ID.

Return Type:
  • integer
Note:
  • The constraint ID is NOT the same thing as the constraint type.
  • The BGE assigns a new--and sometimes different--constraint ID number each time the constraint is created.
Sample Code

 

################  get the constraint ID

# import bge
import bge

# get current scene
scene = bge.logic.getCurrentScene()

# get object list
objList = scene.objects

# get object named Cube_Green
obj1 = objList["Cube_Green"]

# get object named Cube_Red
obj2 = objList["Cube_Red"]

# want to use a 6DOF constraint
constraintType = 12

# get obj1 physics ID
obj1_ID = obj1.getPhysicsId()

# get obj2 physics ID
obj2_ID = obj2.getPhysicsId()

# Use the object center of obj1 for pivot point
pivotPos_X =  0.0
pivotPos_Y =  0.0
pivotPos_Z = 0.0

# create a 6DOF constraint
cube_6DOF = bge.constraints.createConstraint( obj1_ID, obj2_ID, constraintType,pivotPos_X, pivotPos_Y, pivotPos_Z)

# get the constraint ID
id_number = cube_6DOF.getConstraintId()
