I'm making a game in Microsoft MakeCode Arcade for a school project, and I wanted to know if there was a "repeat [function] until [property = true]" type of loop like there is in Luau. I wanted to use this so that the game waits until my player sprite is at a certain coordinate to run some code. I figured out a way to do this in a different way, but I wanted to know just for future reference.
If anyone is wondering, this is what the alternative way I am using.
game.onUpdateInterval(100, function () {
if (level == 1) {
if (myPlayer.x == 950 && myPlayer.y == 140) {
myPlayer.y = 100
myPlayer.x = 10
if (game.ask("Does " + level_1 + " + " + level1_2 + " = " + level1CorrectAns + "?")) {
console.log("Level 1 Completed successfully")
level += 1
LevelChange()
} else {
game.over(false)
}
}
}
})
You could use either while
loop or do...while
loop
For while
loop, the following code will keep on running as long as the condition is true.
let x = 0
while (x < 3) {
x++
}
console.log(x) // print 3
For do...while
loop, the following code will keep on running as long as the condition is true. And this loop will run at least once.
let result = '';
let x = 0;
do {
x = x + 1;
result = result + x;
} while (x < 5);
console.log(result); // print "12345"
Coming back to your example, I believe you're running the loop every 100ms
(based on first argument of your game.onUpdateInterval
.
You could easily do this by adding a timer
function and wrap this loop in as an async function.
const timer = ms => new Promise(res => setTimeout(res, ms))
async function updateInterval() {
while () {
// Your logic here
await timer(100) // You can change the timeout to your desired ms
}
}
updateInterval();
While I'm not 100% sure of the functionality of your current workaround, but this is my interpretation (Hope it works)
const timer = (ms) => new Promise((res) => setTimeout(res, ms));
async function updateInterval() {
let state = true; // This is just a condition if the loop should continue
while (state) {
if (level == 1) {
if (myPlayer.x == 950 && myPlayer.y == 140) {
myPlayer.y = 100;
myPlayer.x = 10;
if (
game.ask(
'Does ' +
level_1 +
' + ' +
level1_2 +
' = ' +
level1CorrectAns +
'?'
)
) {
console.log('Level 1 Completed successfully');
level += 1;
LevelChange();
state = false; // Update the state to false, so it will exit the while loop
} else {
game.over(false);
}
}
}
await timer(100); // You can change the timeout to your desired ms
}
}
updateInterval();
