Problem with pause the node

I am developing a game where characters are fighting. Each character has an attack animation. I need that when one of the characters attacks, the other characters freeze (including animation), respectively, when the character has completed the attack, then the other characters continue from where they stopped. In other words, I need to leave one node active and the others pause.

Animation engine: DragonBones

director.getScheduler().pauseTarget() - does not work. I don’t understand how to make it work
