How can I pause the scene, but have process mode nodes still process physics?

Can someone help me out with something? I am making a game where you have to jump into a mini-game to gain energy. I want the mini-game to lay on top of the main game while it is paused. The only problem is even though I have the mini-game scene’s pause mode set to process none of the collisions are being processed. Is there a way around this? I assumed that if the mini-game scene was set to process pause mode it would still process the physics/collisions of the mini-game?

You say that pausing stops physics server too but you want it active?

Well… it seems that here is your problem

godotengine/godot/blob/15db793ef277b6d2c3aae5e5a075ba2ece31b27a/scene/main/scene_tree.cpp#L871


      
          	debug_contact_mesh->surface_set_material(0, mat);
          
          	return debug_contact_mesh;
          }
          
          void SceneTree::set_pause(bool p_enabled) {
          
          	if (p_enabled == pause)
          		return;
          	pause = p_enabled;
          	PhysicsServer::get_singleton()->set_active(!p_enabled);
          	Physics2DServer::get_singleton()->set_active(!p_enabled);
          	if (get_root())
          		get_root()->propagate_notification(p_enabled ? Node::NOTIFICATION_PAUSED : Node::NOTIFICATION_UNPAUSED);
          }
          
          bool SceneTree::is_paused() const {
          
          	return pause;
          }

As you can see, pause stops the physics servers but set_active is exposed to GDScript so, after setting pause, you can do:

PhysicsServer.set_active(true)

Use Physics2DServer if is for 2D.

Thank you! That did the trick. Everything else is still paused excepted for the mini-game including the collisions.
