VideoCamera problem!

[alealencar]

Hi I'm working with Blender and Morse and have my own Robot class. I follow the www..tutorialsforblender3d.com to make a car. If I use the video camera sensor my code fails, otherwise my code runs ok. The error returned is: AttributeError: 'NoneType' object has no attribute 'getConstraintId'

I don't know why, but if I use VideoCamera, the function getContstraindId returns NoneType.

My configuration is: Ubuntu 16.04 Morse 1.4 Blender 2.76b Python 3.5.2

Minimal builder file to reproduce the issue: run.py

import sys sys.path.append("../xicaum")

from AstraBuilder import from morse.builder import

astra = AstraBuilder() astra.add_service('socket')

cameraL = VideoCamera() astra.append(cameraL)

env = Environment("../teste8/city7.blend") env = Environment("empty") env.properties(longitude = 0.0, latitude = 0.0, altitude = 0.0)

AstraBuilder.py

import sys

sys.path.append("../wl")

sys.path.append("../xicaum")

from CarClass import *

from NetworkInterfaceCard import *

from morse.builder import *

class AstraBuilder(Robot): def init(self, name = None): Robot.init(self, "astra.blend", name)

    #add odometry
    odometry = Odometry()
    #odometry.translate(0,0,0)
    self.append(odometry)

    pose = Pose()
    #pose.translate(0,1.3,0.2)
    self.append(pose)       

    #add gps
    gps = GPS()
    #gps.translate(0,1.3,0.2)
    self.append(gps)

    #add imu
    imu = IMU()
    #imu.translate(0,1.3,0.2)
    self.append(imu)

    #velocity
    velocity = Velocity()
    #velocity.translate(0,1.3,0.2)
    self.append(velocity)

    print("end builder CarAstraBuilder")

Hi Alealencar,

inside your .blend file there are 4 python scripts (Suspension.py, getRound.py, CarSetup.py, CarAstraController.py). I have had troubles using files like that: when launching MORSE, blender couldn't find these scripts. Try extracting them in your file system (eg: /home/you/scripts/... ), put their location inside your PYTHONPATH and see if the error message changes.

Hi Nicolaje,

I've tried what you said, but I get the same result.

File "CarSetup.py", line 75, in Car_Constraint constraint_ID = vehicle_Constraint.getConstraintId() AttributeError: 'NoneType' object has no attribute 'getConstraintId'
