Is there any way to check if a timer exists?
if im true understand i add second 5 or 10 so i understand timer work.
If a timer exists, its value is not 0.
As soon as you check a timer’s value, GDevelop will create the timer if it doesn’t already exist.
If I want the timer to count after one event, should I place that timer checking condition as a child of that event?
If you place it as a subevent, it’ll only get checked if the conditions in the parent event are true. If this is how you want it to work, then yes.
