I've been searching the internet all day and I can't find the answer I'm looking for.
In my HUD I want to use orange dots to represent lives. The user starts off with 5 lives and every time they die, I want a dot to be removed. Pretty straight forward.
So far my idea is to make a movie clip that has the five dots in a line. There would be 5 frames on the timeline (because after the last life it goes to a game over screen right away).
I would have a variable set up to store the number of lives and a function to keep track of lives. So every hit of an obstacle would result in livesCounter--;. Then I would set up something like this:
switch(livesCounter){
case 5: livesDisplay.gotoAndPlay(1);
break;
case 4: livesDisplay.gotoAndPlay(2);
break;
case 3: livesDisplay.gotoAndPlay(3);
break;
case 2: livesDisplay.gotoAndPlay(4);
break;
case 1: livesDisplay.gotoAndPlay(5);
break;
}
I feel like there has to be an easier way to do this where I could just have a movie clip of a single orange dot that I could replicate across an x value based on the number of lives. Maybe the dots would be stored in an array? When the user loses a life, a dot on the right end of the line is removed.
So in the end the counter would look like this:
* * * * *
* * * *
* * *
* *
* (last life lost results in the end game screen)
