LUA error: One of the function's argument type is not correct. (simAddForceAndTorque)

[AndreaCensi]

I changed the path in the LUA file.

I get the following error when hitting "play":

Any idea?

Thanks, A.

Hi Andrea,

I got this error the other day when I tried to hit Play without first doing

% chmod +x pyquadsim_server.py

If you've done that and it still doesn't work, let me know.

[AndreaCensi]

Yes, I had done that. ​

[simondlevy]

And you're using the current release of V-REP, 3.1.3?

[AndreaCensi]

Yes, 3.1.3 rev 2.

[simondlevy]

Make sure you also do this, from the instructions:

Once you've installed V-REP and PyQuad Stick and downloaded PyQuadSim, launch V-REP and open the pyquadsim.ttt script from the pyquadsim folder. Go to the Tools menu, select Scripts, and double-click on Child script (associated with Quadricopter). Edit the value of the PYQUADSIM_HOME variable to reflect where you put the folder

Hi I am having a similar problem, I am running the package on Macbook Pro mountain lion and have downloaded vrep 3.1.3. what currently happens is one of two things either:

Over wise it will seemingly work, but the pygame console will just continualy load...

Hoping that you might be able to help me out.

Thanks in advance Nathanael

hello, congratulations for the work, I am having the same problems:

Lua API call error: [string "SCRIPT Quadricopter_propeller_respondable1"]: 23: One of the function's argument type is not correct. (simAddForceAndTorque) Lua API call error: [string "SCRIPT Quadricopter_propeller_respondable3"]: 23: One of the function's argument type is not correct.

(simAddForceAndTorque) Lua API call error: [string "SCRIPT Quadricopter_propeller_respondable4"]: 23: One of the function's argument type is not correct. (simAddForceAndTorque) Simulation stopped.

I am using: V-rep: 3.2.0 Virtualenv + python2.6 OSX Yosemite 10.10

during the simulation the V-rep the Quadrotor down up and after closing. Any help?

[swenzel]

I don't have this issue but it sounds as if there is a problem decoding the data that was sent by the server. I think that might come from some int that sneaked through. Maybe you can try changing https://github.com/simondlevy/PyQuadSim/blob/master/pyquadsim_server.py#L54 to client.send(struct.pack('%sf' % len(data), *(float(i) for i in data))) to force all numbers to be floats.

Edit: Sorry, looking closer at the source code I don't think this is the problem, all values should be floats. However I can reproduce this when I raise an Exception after connecting to the client. If the exception is thrown within the mainloop I get the stack trace in the pygame window so if you don't see that, your problem should be within 109 and 133. Do you see any exception printout in the console where you started vrep?

Similar problem here. Using windows 7. Any idea so far Simon?

Same problem. Even tried hard coding some floats.
