Hi I have a simple AI that I want to control the attack speed of an enemy unit. Basically giving him some extra time when he has a debuff. But I was wondering if it is possible to change the Wait Task “Wait Time” during runtime? I was wondering If I need to do it in c++ by making a child class wait time and setting it up by myself? Or if it’s a better way to do it in blueprint.

I kind of made it work with a service where in code I can change the Interval time but when doing it in the Behavior Tree the time is almost double to what I set.

Any help would be greatly appreciated.  
Regards

I got it working with “Wait Blackboard Time” and setting up the certain time in code. So now it works as it should.
