CoppeliaSim forums

Hello, I recently encountered an issue. I added an RG2 gripper to a UR5 robotic arm and created a new Lua script file under this gripper. I tried using the function sim.callScriptFunction('rg2Close@UR5/RG2', sim.sim_scripttype_childscript, {}, {}, {}, '', sim.simx_opmode_blocking) in the console to call a function within this script, but it reported the following error:
​​"in sim.callScriptFunction: one of the function's argument type is not correct."​​

After fixing the error, it then reported:
​​"sim.callScriptFunction: script does not exist."​​

Another question: Could this be due to incorrect input parameters? I thought I might need to pass the script handle into the function. However, when I tried to retrieve the script handle using scriptHandle = sim.getObjectScript(objectHandle) in the console, it gave me the error:
​​[string "local scriptHandle = sim.getObjectScript(obje..."]:1: attempt to call a nil value (field 'getObjectScript')​​

This problem has been bothering me for a while. I would greatly appreciate your help when you have time. Thank you very much!

Hello,

what CoppeliaSim version are you running?
As of CoppeliaSim V4.9, best would be to call your script function with:
Keep in mind that in the RG2 model, the script is attached to RG2 and should be addressed as '/UR5/RG2/Script', or whatever name that script has (Starting with CoppeliaSim V4.7, script are stand-alone scene objects on their own)

Cheers
