CoppeliaSim forums

Recently, I downloaded the latest version of Coppeliasim, but during use, I found that the retrieval of handles in the script is not the same as in previous versions, and I did not understand the relevant instructions for obtaining handles in the user manual. During the simulation process, errors also occurred, as shown in the figure. What is the correct method to obtain a handle? Thank you.
Cheers

Make sure to carefully read the page on accessing scene objects programmatically for additional details.

In your example, you'r access objects correctly with:
