is there a way to stop a timer

in my game I want if you stand on lava ground for long enough you will die but if you get in a certain suit you will live but, I don’t know how to stop a timer! can anyone help me? I don’t know if there is a possible way to do this so that is why I am putting it under Feature Requests instead of How To.

here is a link to my game this only takes place in THE CORE to get to the core you must go underground and fall off the cliff

now to get to THE CORE you must put in the secret code which I will tell you if you message me. it is not a cheat code you obtain it after getting to the end of each biome unless of course you cheat to get it then I guess it is a CHEAT code

please help

Use Reset on the timer to stop it.

that is exactly what I did here and it did not do anything

Well yeah, it will start again when you touch the ground again.
The Reset is to stop the timer after it has started (or after you use “start”).

What you want is to not let the timer to start at all after getting the suit, like a switch.

thank you!
