Hey there, I'm having trouble accessing the variable from the KeyCodeClass. Let me walk you through what I've tried so far: Attempt 1
class KeyCodeClass1 {
constructor() {
this.space;
}
KeyDown(e) {
if (e.keyCode == 32) { this.space = true }
}
KeyUp(e) {
if (e.keyCode == 32) { this.space = false }
}
}
var KeyCode1 = new KeyCodeClass1();
window.addEventListener("keydown", KeyCode1.KeyDown, false);
window.addEventListener("keyup", KeyCode1.KeyUp, false);
setInterval(loop1,10);
function loop1() {
console.log(KeyCode1.space);
}
Currently, my console is showing undefined. Even when I press the spacebar, which has a keycode of 32, the value remains undefined. To try and resolve this, I created a function to return the value:
Attempt 2
class KeyCodeClass2 {
constructor() {
this.space;
}
KeyDown(e) {
if (e.keyCode == 32) { this.space = true }
}
KeyUp(e) {
if (e.keyCode == 32) { this.space = false }
}
Space() {
return this.space;
}
}
var KeyCode2 = new KeyCodeClass2();
window.addEventListener("keydown", KeyCode2.KeyDown, false);
window.addEventListener("keyup", KeyCode2.KeyUp, false);
setInterval(loop2,10);
function loop2() {
console.log(KeyCode2.Space());
}
Still getting undefined in the console. In the third attempt, I initialized this.space in the constructor with either true or false:
Attempt 3
constructor() {
this.space = false;
}
Now, the console displays false. However, pressing the spacebar does not change it to true.
It got me thinking about whether the functions within the class are functioning properly. Here's an example to demonstrate that they are indeed working: Attempt 4
class KeyCodeClass4 {
constructor() {
this.space = false;
}
KeyDown(e) {
if (e.keyCode == 32) {
KeyCodeClass.space = true;
console.log("space Down");
}
}
KeyUp(e) {
if (e.keyCode == 32) {
KeyCodeClass.space = false;
console.log("space Up");
}
}
}
var KeyCode4 = new KeyCodeClass4();
window.addEventListener("keydown", KeyCode4.KeyDown, false);
window.addEventListener("keyup", KeyCode4.KeyUp, false);
I am troubleshooting like this to enhance the readability and comprehension of my code. Any assistance you can provide on this matter would be greatly appreciated.
