[Question] About action graph extension

[1izeyi]

Can I use the action graph extension in isaac sim 4.5 or 5.0? I have customized some nodes and I am using the direct workflow so will that make it easier?

Yes, the action graph extension is supported in both Isaac Sim 4.5 and 5.0, allowing workflows that include custom nodes and the direct workflow approach.

@RandomOakForest Thank you very very much！Sir！But I'm still confused now. I'm using the direct workflow in isaaclab. How do I enable my action graph extension? I'm currently using an omni.physx.graph.OnTriggerCollider, an official node, and I customized a Python API node. Now I have two questions.
1、Firstly, how do I enable both extensions and enable the action graph in the isaaclab direct workflow?
2、The second question is, can I detect collisions directly in the simulation loop without using an extension? I did do that, but the mesh collision detection relies on the official node On Trigger, so can our official extension be independent of the extension import module?
I'm a newbie, but I have this difficult and urgent task now. Could I ask your team for some code demos? I wonder if you have any suggestions. Finally, I'm very sorry to bother you, but I'm really anxious. Crying...

Following up, I will move this post to our Discussions section. Is there an example you are working on that we could use as a reference? Thank you for your interest in Isaac Lab.
