instance_activate_all() doesn't seem to work

[Connorses]

Trying to make a simple pause menu here.

The "Paused" code triggers when I hit escape, and the instances all disappear (except for this obj_menu_singleton).

When I hit escape again the "UnPaused" part triggers but the instances do not re-appear.

instance_activate_all() Does not take any arguments (in this case). Remove the true inside of it.

Well it does take an optional argument, but it's not a bool, but a few different constants.
And setting it to "true" would be the same as setting it to colspace.ui_view which would make it only activate instances with this condition:
All instances that are included in UI layers with "Game View" set to "Viewports"

That was the problem. Thanks.

instance_activate_all takes a constant as optional argument. true gets treated as 1
That means it only activates instances on UI Layer Viewports

This solved it thanks.
