Problem about the physics plugin can't find body with DEF name

[izzm123]

Hi, I have created a physics plugin for the simulation world, and I used the function dWebotsGetBodyFromDEF( ). The solid nodes in the scene tree have been defined with DEF names. These names were used as the variables of the function dWebotsGetBodyFromDEF( ). The physics plugin has been added to the worldinfo.

As a consequence, when the world was run, the function dWebotsGetBodyFromDEF( ) returned NULL.

could you give me some suggestions?
Thanks!

From the way you describe it, it should work. Can you provide a simple example of world/plugin that shows the issue?

Thank you for taking time out of your busy schedule to help me with the issue. Above are some screenshots of the issue.

The issue is that you didn't define the physics field of your Solid and therefore the body doesn't exist on the physics engine side. Adding it should fix your issue
