Working with the timer

I can’t understand the logic behind applying the timer. I need the event to last 5 seconds, how do I do this? Thank you in advance!

Please elaborate, lasting 5 seconds can have multiple meanings (the effects are reversed after 5 seconds, the event triggers every frame for 5 seconds…)

For example, to add +1 every second to the scene variable for five seconds

Or that would increase the weight of the object for five seconds

Here an example of timer in the first event Reset timer
In the second event Check if the timer reach x seconds and do someting

In this sample I Reset “DestroyMe”
And check if “DestroyMe” is greater than 0.1 Delete the object.
