I am currently developing a game using HTML/JavaScript, and I have implemented a "special ability" that can only be activated once every x seconds. To indicate when this ability is available for use, I have created a graphical user interface element. Since I am incorporating CSS animations in my project, I need to determine whether the animation on this element has completed upon a keypress event.
Instead of utilizing addEventListener, I aim to achieve this functionality through a straightforward if statement. However, I am uncertain about the feasibility of this approach.
The code snippet I have so far is:
var keystate = {};
window.addEventListener("keydown", function(e) {
keystate[e.keycode || e.which] = true;
}, true);
window.addEventListener("keyup", function(e) {
keystate[e.keycode || e.which] = false;
}, true);
window.setInterval(function() {
if (keystate[87]) { //w key, THIS is where I want to check if the animation has completed as well
//do stuff
document.getElementById("circle_flash_glow").classList.add("circle_flash_use");
}
}, 16.666666666666667);#svg_circle_loader {
position: absolute;
right: 0;
bottom: 0;
background: none;
border: none;
margin: none;
padding: none;
}
#circle_flash_loader {
fill: none;
stroke: #F00;
stroke-width: 10px;
stroke-dashoffset: 80;
animation-fill-mode: forwards;
}
.circle_loader_load {
animation: circle_flash_loading linear;
animation-duration: 2.5s;
}
@keyframes circle_flash_loading {
0% {
stroke-dasharray: 0, 314;
}
100% {
stroke-dasharray: 314, 0;
}
}
#circle_flash_glow {
fill: none;
stroke: #F00;
stroke-width: 0px;
animation-fill-mode: forwards;
opacity: 1;
}
.circle_flash_use {
animation: circle_flash_pulse 0.6s ease-out;
}
@keyframes circle_flash_pulse {
0% {
opacity: 1;
stroke-width: 0px;
}
100% {
opacity: 0;
stroke-width: 70px;
}
