Wanna make in our game that, when player dies there comes a return and revive button. I use a reward ad with google ads for that, when video is seen you revive all that works, but when it is used on google there is a 15 min time before it can be used again, so how to I make it so the opacity turn down and up again when 15 min has gone by.?? also with player closing the game too.. read about unixtime so that mabye be on way to tackle it, but have not used unixtime before so please help
:)
