When the player dies, I'm using "deactivate group" (in a function). When the player still has 1 life, it's ok because i'm restarting the level (all groups are switching back to active mode).
But when the player has 0 life i send the player to the score layout and then (if he still want to play) to the game layout. Then, I need to activate all the deactivated group in "on start of layout"... I'm pretty sure this is not a nice way to handle the problem...
Thanks for helping me!!
