What does the parameter 'flag' for SceneTree.call_group mean?

+5 votes

I can see that there are constants in the SceneTree class:

GROUP_CALL_DEFAULT = 0
GROUP_CALL_REVERSE = 1
GROUP_CALL_REALTIME = 2
GROUP_CALL_UNIQUE = 4

But the default value fails in my usage of the call_group of my project. It works with the 'realtime' value.

I would like to know what's the difference between each flag.
Thanks

Best answer
GROUP_CALL_DEFAULT = 0 - Regular group call flag (no flags).
GROUP_CALL_REVERSE = 1 - Call a group in inverse-scene order.
GROUP_CALL_REALTIME = 2 - Call a group immediately (usually calls are delivered on idle).
GROUP_CALL_UNIQUE = 4 - Call a group only once, even if call is performed many times.

I know you asked this question last year, but I found the answer (maybe you have too).
I'll post it for other people wondering ;)
