Point To Point Constraint: constraint_id

constraint_id
  • 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 point to point constraint
constraintType = 1

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

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

# Use front bottom right corner of obj1 for pivot point
pointPos_x = 1.0
pointPos_y = -1.0
pointPos_z = -1.0

# create a point to point constraint
cube_PtoP = bge.constraints.createConstraint( obj1_ID, obj2_ID, constraintType,

pointPos_x, pointPos_y, pointPos_z )

 
# get the constraint ID
id_number = cube_PtoP.constraint_id
