I've created an extensive Hunger,Thirst,Fatigue system using Status Effects and formulas. I did research, I read tutorials and forum. So far I am successful in making status effects for different levels of sleepiness that use a status value called Rest that decreased over time. (When rest is <90%, slightly drowsy effect is applied which lowers certain status values.)
I'm stuck at this part: (When rest <60%, you have a 1% chance of falling asleep per hour) the status effect handles the having rest<60% and would then activate another status effect of being asleep which restores rest.
I can't find how to make the formula wait 60 seconds before checking chance.
