I’m using UE 5.5.4. My Blueprints:
When I pressed G key the Set timer by Event don’t fire. There is no delay.
How do you know it does not fire? How are you testing it? Is the smoke from the explosion? If so, it clearly did fire (no pun intended).
Set timer by Event don’t fire. There is no delay.
Which one is it then? There’s no delay or it does not fire? Sounds like these two are mutually exclusive. Please clarify.
And I find the blueprints logic is when I hit the key, it fire an explosion. And if I don’t hit the key again, after 1 second of hitting the key. It will fire an explosion. And print message “Stop VFX Timer”.
So it’s working as intended. That’s what the script you have does. Bar the fact that the timer clearing does not really do anything.
If that’s not what you want, perhaps describe - step by step - how you would like it to work.
Yes, forgive my wrong expression. I want the Set timer by event to repalce delay node for optimization. In this logic it can’t
This has nothing to do with optimisation. It’s unclear how you want it to work vs how it’s working atm. Consider describing the desired behaviour using bullet points. What is supposed to happen?
There is nothing wrong. It can replace delay node. I keep pressing the key, so it keep firing. And showing no delay. Forgive me for this stupid question
