Modifying a variable in javascript? Not Working -

-

i'm trying make when pacman runs ghost loses life. , according number of lives has specific message displayed, variable doesnt seem taking account i'm changing it.

any suggestions?

var life=3; // lorsque l'on rencontre un fantome. function mancheperdue() {    x_pacman = 13;   y_pacman = 10;    life = life-1;    if (life=2) {     window.alert("2 lives left");   }   else if (life=1) {     window.alert("1 life left");   }   else {      window.alert("game over");     gameover();   } }

you need use equality operator == in if's, not assignment operator =.

if (life == 2) {   alert("2 lives left"); else if (life == 1) {   alert("1 life left"); } else {   alert("game over");   gameover(); }

using = means you're reassigning value in each check. example:

var lives = 3; if (lives = 1) {   alert("1 life"); // show } alert(lives); // show "1"!

javascript has idea of strict equality using === operator. in case of strict equality, types must match.

1 == 1; // true 1 == "1"; // true 1 === "1"; // false

for it's worth, you'll notice don't need write window.alert, writing alert suffice because window global scope.
