If I click multiple times, how can I get multiple outputs? (click many times within the duration)
- the first click executes and starts a timer with a specific rate (providing you do not want the first one delayed - not explained here)
- add any follow-up clicks to an array if they happen often enough
- if array is not empty, the timer fetches element 0
- execute & remove element 0
- check if the array is empty, if so - kill the timer
It will be a tad more complex if you need to preserve precise timings between the clicks. As in:
- 2nd - 2.52s
- 3rd - 2.95s
- 4th - 3.5s
And you wanted to fire them back with the exact same timings. But that was not mentioned in the ask.
I would do something like this: create a class of actor that on begin play it has this delay and print string and a destroy actor function at the end.
Then, when pressing the respective button, I would just spawn this actor. With this, I could spawn multiple actors and everyone would have its own delay.
Sorry, unfortunately, that’s exactly what I’m trying to realize.
Like if inputs: 1st 0s, 2nd 1.1s, 3rd 2.4s, …
then I want to print string at 1st 0+5s, 2nd 1.1+5s, 3rd 2.4+5s, …
it’s so hard 
Thank you for your reply!
Indeed, it meets my current need. I successfully realized my function in your way.
But the problem I found still troubles me.
And by the way, I think if I figure it out, it’ll be a better way in my case. 
Thank you so much!!! 
The solution perfectly solved my problem. Actually, I’m kind of new to ue, and I spent lots of time trying to figure out this problem.
I’m so excited that I got the solution from you.
Still trying to understand the logic.
Thank you！
