The condition “timer Coin>0.1 secs” cannot be a sub-event. Drag it to the left.
Or maybe your global variable is not working.
And you need to pause your timer Coin after Wait 10 seconds, or coins will keep being created.
It might be your second event.
“The number of scene variable feverTime = 1”
As long as that’s true, it will keep resetting the timer “Coin” over and over again so the timer never reaches 0.1 second.
Maybe put “trigger once” with that event.
Also I’m not sure how that fourth event would affect the other events since it’s constant but there’s a wait time.
