Hello, I think I found a bug in the omni.anim.people extension v.0.1.9.
The extension stopped working for me after updating.
The issue seems to come from the following file:
omni.anim.people-0.1.9\omni\anim\people\scripts\commands\idle.py
After changing line 22 from
self.set_variable("Action", "None")
to
self.character.set_variable("Action", "None")
the issue was fixed.
Please fix this in the upcoming version.
Thats the correct fix. Idle is the default state regardless, so that character will go to Idle after finishing a command.
We’ll add the fix in the next release.
Hello,
I got some early access to Isaac Sim 2022.2.1 and noticed this bug is not yet fixed.
Also I found another bug:
In the function get_avoid_angle in /omni.anim.people-0.1.9/omni/anim/people/scripts/navigation_manager.py the variable movement_vector is sometimes 0, which results in a division by 0. I noticed this when increasing the number of agents in the scene to more than 100. This results in a lot of agents staying put when they should move somewhere.
I created a simple test scene where you can reproduce the second error. Here you have the usd file and cmd.txt file:
cmd.txt (3.7 KB)
Example_omni.anim.people_error.usd (8.9 KB)
The error log when you click on play:

This issue should be fixed with the latest release of Isaac Sim.
