I am trying to make me character moving left and up and I think jump() and slideLeft()
functions are working properly and the problem is in the controller(e) function (else if (e.KeyCode===37)) . The first function is avaible but it isn't able to acces the second conditon function. Also, I would want to make the grid solid after I will make an slideRight() similar function ,so if my character is jumping on it, the platform would sustain the square . Has anyone any ideea for either of my questions ?
Code snippet:
var square = document.querySelector('.square');
var grid = document.querySelector('.grid');
var bottom = 0;
let isJumping = false;
let isGoingLeft = false;
var newBottom;
let left = 0;
let leftTimerId;
function jump() {
if (isJumping) return
let timerUpId = setInterval(function() {
if (bottom > 250) {
clearInterval(timerUpId);
let timerDownId = setInterval(function() {
if (bottom < 0) {
clearInterval(timerDownId);
isJumping = false;
}
bottom -= 5;
square.style.bottom = bottom + 'px';
}, 20)
}
isJumping = true;
bottom += 30;
square.style.bottom = bottom + 'px';
}, 20)
}
function slideLeft() {
console.log('da');
isGoingLeft = true;
leftTimerId = setInterval(function() {
left -= 5;
square.style.left = left + 'px';
}, 20)
}
function controller(e) {
if (e.keyCode === 32)
jump();
else if (e.KeyCode === 37)
slideLeft();
}
document.addEventListener('keydown', controller);.grid {
position: absolute;
background-color: chartreuse;
height: 20px;
width: 500px;
bottom: 100px;
left: 100px;
}
.square {
position: absolute;
background-color: darkblue;
height: 100px;
width: 100px;
bottom: 0px;
left: 150px;
}
`<div class="grid"></div>
<div class="square"></div>EDIT: There is a typo: The second time you've written KeyCode
function controller(e) {
if(e.keyCode===32) {
jump();
}
else if(e.keyCode===37) {
slideLeft();
}
}
I don't really understand what you mean by the second part of your question. If you want a character to have the ability to jump on a square, you'll have to implement a collision detection. Something like this:
if ( isNotOnGround() ) {
fall()
}
