for last 3 hours i have been trying to find out how to execute a line of code multiple amount of times. Its going like this: typing something turns boolean to true and after activating it i want mod to repeat an action until stopped by changing boolean to false. I firstly tried while loop but it crashed the game so im guessing its not an option. Then i tried to do every 40ticks but i always get errors when trying to use phase.

My question is: how do i repeat the same thing every 2 seconds?

Note: its for forge mod 1.16.5

i tried using phase but that didnt work as i mentioned. I have no other ideas on how i can make it work

Please keep in mind that im very new to such things and its my first project.
