ok heres what i need help with


with this the score counts down from 10 to 0
1 for every coin the main MC hits

if (_root.coin.hitTest(this.hero_hit)) {
collected_coins++;
_root.level1_text.text = 10-collected_coins+" more to go";
}

i tryed to duplicate this to make a "lives" system, but it didnt work
it keeps showing up in the actual game as "NaN left"

if (_root.wall.hitTest(_x, _y, true)){
lives_left++;
_root.lives.text = 5-lives_left+" left";
}


can anyone tell me what im doing wrong?

Hi,

I suspect that your issue is that you havn't told Flash that "lives_left" is a variable before trying to increment it. Try setting the value of the variable to 0 before using the variable...

lives_left=0;
if (_root.wall.hitTest(_x, _y, true)){
lives_left++;
_root.lives.text = 5-lives_left+" left";
}

hope it helps

ok, i replaced the code as you wrote, and it doesnt shoe up as "NaN left" anymore

now it counts down to 4 but stops there and wont go any farther

Hi,

The example was not meant as a cut and paste code sample. It was to show that a variable needs to be declared before being used....at least since Flash8. Where you declare your variables is also important. Try declaring the variable outside of the hitTest.....in fact, above all other code except for other variable declarations.
