Notes

Here are the general steps to create your own Not Fancy Mario Jump. There's not much JavaScipt logic in this app. Most of the heavy lifting is done through CSS @keyframes. JavaScipt is mainly used to apply the animation class when the button is clicked.

1. Create the @keyframes Animation

The first step is to create our animation. This is quite a simple animation. Mainly I'm using the bottom property to move the item.

/* Calling the animation */
.mario.jump img{
  animation-name: jump;
  animation-duration: 1s;
  animation-timing-function: cubic-bezier(.87,-.41,.19,1.44);
}

/* The animation */
@keyframes jump {
  0% {
    bottom: 0;
  }
  50% {
    bottom: 91px;
  }
  100% {
    bottom: 0;
  }
}

2. Using JavaScript to apply the animation class

This will apply the animation class and trigger the animation.

Here's what it looks like in the html file. This will apply the jump class when isJump is triggered

<div
  :class="{'jump': isJump}"
>
  <img src="images/mario.png" alt="">
</div>

Here's our vue file. This is what the isJump data looks like

new Vue({
  data: {
    isJump: false,
  },
  methods: {
    jump() {
      this.isJump = true;
    }
  }
})

3. Remove animation class

Once the animation is completed, we'll remove the animation class. We're utilizing the animationend event. This even will fire when a CSS animation has completed. Cool, right! I thought we would need to do some setTimeOut, luckily I found this event. Yay! 👏

<div
  @animationend="isJump = false"
>
  <img src="images/mario.png" alt="">
</div>
