Blender 2.71 crashes on constraints in BGE

I’m trying a simple example from the API documentation and it’s crashing Blender as soon as I run the script. It crashes on the constraints.createConstraint call. Does anyone else have the same problem?


from bge import logic
from bge import constraints


# get object list
objects = logic.getCurrentScene().objects


# get object named Object1 and Object 2
object_1 = objects["Cube1"]
object_2 = objects["Cube2"]


# want to use Edge constraint type
constraint_type = 2


# get Object1 and Object2 physics IDs
physics_id_1 = object_1.getPhysicsId()
physics_id_2 = object_2.getPhysicsId()


# Use bottom right edge of Object1 for hinge position
edge_position_x = 1.0
edge_position_y = 0.0
edge_position_z = -1.0


# use Object1 y axis for angle to point hinge
edge_angle_x = 0.0
edge_angle_y = 1.0
edge_angle_z = 0.0


# create an edge constraint
constraints.createConstraint(physics_id_1, physics_id_2,
                             constraint_type,
                             edge_position_x, edge_position_y, edge_position_z,
                             edge_angle_x, edge_angle_y, edge_angle_z)

Can anyone else please try this script and let me know if it works, so that I can narrow down the problem to Blender or my PC? Thanks.

Not sure if im setting it up right, but i run the script everyframe and have Cube1 and Cube2 in the scene. No crash. Tried all physics types.

Looks right. It must be something with my setup then. Win8 Radeon R9 270. Thanks for testing.

I went back to Blender 2.70 and my problem went away.
