Are you talking about resetting them for when the player clicks on new game? or just in general, for debugging purposes?
If it's in general then you could create called by other actions which contain set condition/value to x when called or you could use Lua & create 2 tables. One containing the name & default state of each condition & same again for each value. Then you would use a for loop & iterate through each entry to set it back to default value.
* technically I believe it would be possible to have it automatically create the tables on game launch... but it's way too early for me to wrap my head around that *
If it's for a new game then I have already posted multiple threads on how to go about doing that. check this thread:
