useful thing i found out about yesterday i thinks

ackvonhuelio

for programmers
something useful if you have a variable you want to change back and forth from 0 to 1

code that people usually use:
function toggleFrom0to1(){ if(x === 0){ x = 1; }else{ x = 0; } }

thing thats useful:
var x = 0; function toggleFrom0to1(){ x = 1-x; }

ackvonhuelio Is there a way to detect if a value, for example, sprite.y, is between 2 numbers?

Varrience

or you could just use a bitwise xor operator to change between both as well
Examples:
var a = 0; a = !a // this will give us false but in js false is considered as 0 rather than one a ^= 1; // however this is my favorite method converts all matching 0's to 1 and 1's to 0 /* as you can see there really isn't much need for a function for something simplistic as this by using xor(^) makes it really simple by converting matching numbers that are 0 to 1 and reducing 2 1's in corresponding places to 0 so 0b001(1) ^ 0b001(1) returns [0] & 0b000(0) ^ 0b001(1) returns [1] and from what i remember bitwise operators are pretty fast so it could also be a minor boost if this is what your looking for */

interesting

You can use ``` to create entire blocks of code. Like this:

function myFunction(input) {
  return input+2;
}

```js
function myFunction(input) {
return input+2;
}
```

umm
if(sprite.y>10&&sprite.y<100){

}

Thanks!

I don't know how I didn't realize that already lol

One more question: how do you round the result of a number to a closest custom integer(i.e. rounding sprite.rotation of 63 to 90, or 201 to 180)?

esw

function angleCap(num) {
    let angle = num % 360 // provides a number within 360
    for (var deg = 0; deg <= 360; deg += 90) {
        if (deg >= angle) { return(deg) }
    }
}
/*
Note this expression should only be invoked when rounding
However if we are doing integer rounding between two ranges maybe something like this would be better
*/
function angleCap(num){
    return Math.round(num % 360 / 90) * 90
} // we can also use Math.floor & Math.ceil to also change the effects of rounding

Unknowing-Thorax

even better:

var x = true;

x = !x;

will make it false
and if false will make true

activate with a button or something

Varrience

Unknowing-Thorax I actually posted that before up top and another method that i do like a bit better than using the ! operator it's actually the 1st reply

INTERNECION

This code. I feel like I have seen it before somewhere. I just don't know where. hmm
