Getting triggers to work at certain points?

I’ve got some matinee’s setup to trigger when the camera points at them.
But I don’t want them to be active until until something else is triggered.

So once trigger 1 is activated. Triggers 2,3,4 become live.

I thought I’d be able to set a flag at the end of the trigger 1 blueprint which I could check for at the start of the blueprints for 2,3&4?

Can anyone point me in the right direction?

I’d set a branch at the start of the later actions and check a bool you can set at the end of the previous action. So, trigger 1 action happens and sets ‘Did1Trigger’ to true. Trigger 2 has a branch checking ‘Did1Trigger’ and does nothing on False and executes on true. Also at the end of the action on true you would set ‘Did2Trigger’ to true and repeat for all triggers.

Might be better ways others know of, but that should work to start.
