i was wondering if switches runs continuously or does not need of setIntervals to run (forever). i'm making a game where in a level value changes and the switch will change all entities position based on the level;
let LEVEL = 0;
switch (LEVEL) {
case 1:
player.x = 64;
player.y = 64;
enemy.x = 32;
enemy.y = 32;
break;
case 2:
player.x = 0;
player.y = 64;
enemy.x = 72;
enemy.y = 56;
break;
}
No. A switch is like every other statement in JavaScript: It only runs when it's reached in the step-by-step execution of the code. Your example would run exactly once, for instance. To run more often would require that you put it in a loop (but then nothing else can run except that loop) or, as you said, call a function that contains the switch from a timer.

Put the switch in a function that you call when you change the level.
