creating a delay after a collision

CSoulo

Hey, I'm trying to create a delay in-between when a collision occurs and when I have my game over screen to pop up. I want the program to still be running but have a five second delay before game over shows up. I've tried a few methods such as using millis() but it always starts right when I start my program. Could someone tell me how I should go about this? thanks in advance.

boolean doom_timer_active;
int doom_timer;

if( collision ){
  if(!doom_timer_active){
    doom_timer = millis() + 5000;
    doom_timer_active = true;
  }
}
if( doom_timer_active && millis() > doom_timer ){
  game_over();
}

I love you
