Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

引用方法

  • 推荐作为依赖使用

    • npm install tinyjs-plugin-dragonbones --save
  • 也可以直接引用线上cdn地址,注意要使用最新的版本号,例如:

    • https://gw.alipayobjects.com/os/lib/tinyjs-plugin-dragonbones/0.5.0/index.js
    • https://gw.alipayobjects.com/os/lib/tinyjs-plugin-dragonbones/0.5.0/index.debug.js

起步

首先当然是要引入,推荐NPM方式,当然你也可以使用CDN或下载独立版本,先从几个例子入手吧!

1、最简单的例子

参考 demo/simple.html

引用 Tiny.js 源码

<script src="https://gw.alipayobjects.com/os/lib/tinyjs/tiny/1.3.1/tiny.js"></script>

首先从 DragonBones Pro 中导出一份骨骼动画数据,再将导出的 Dragon_ske.json,Dragon_tex.json 和 Dragon_tex.png 添加到项目中,使用 Tiny.Loader 模块加载资源完成后,可以创建基于 DragonBones 的骨骼动画:

var loader = new Tiny.loaders.Loader();
loader
  .add('dragonBonesData', './resource/Dragon/Dragon_ske.json')
  .add('textureDataA', './resource/Dragon/Dragon_tex.json')
  .add('textureA', './resource/Dragon/Dragon_tex.png')
  .load(function (loader, resources) {
    initDragon(resources);
  });

实例化 DragonBones 所需要的数据:

//设置别名
function initDragon(resources) {
  // 将骨骼数据添加到骨架系统中
  Tiny.DragonBones.addDragonBonesData(resources['dragonBonesData'].data);
  Tiny.DragonBones.addTextureAtlasData(resources['textureDataA'].data, resources['textureA'].texture);

  // 通过 buildArmature 方法,我们提取名称为robot的骨架,一个包含骨架数据的 Tiny.Container 对象。要想在舞台中看到该骨架,我们需要将其显性的添加到的舞台当中
  armatureDisplay = Tiny.DragonBones.buildArmatureDisplay('Dragon');
  armatureDisplay.x = app.renderer.width * 0.5;
  armatureDisplay.y = app.renderer.height * 0.5 + 150;
  armatureDisplay.scale.set(-0.3, 0.3);

  // 播放骨骼动画动画名字需要在 DragonBones Pro 中定义,如 fall、jump、stand、walk
  // 也可以使用 armatureDisplay.animation.play('walk');
  var animationState = armatureDisplay.play('walk');

  container.addChild(armatureDisplay);
}
2、多人物骨骼动画

参考 demo/multi.html

3、改变动画速度

参考 demo/timescale.html

有时在游戏的运行过程中,需要动态的改变动画的播放速度。对时钟的调节一般是要影响一组动画。直接调节 animation 中的 timeScale 属性即可。

var animationState = armatureDisplay.play('walk');

// 调节动画速度为 1.5 倍
armatureDisplay.animation.timeScale = 1.5;
4、动画遮罩

参考 demo/bonemask.html

动画遮罩就是只将动画的一部分呈现出来,例如下面的代码,将只播放 head 和 body 两个骨头的跑步动画,其他骨头将维持原姿势不动。

var animationState = armatureDisplay.play('walk');
animationState.addBoneMask('head');
animationState.addBoneMask('body');
5、动画混合

参考 demo/mixed.html

动画混合是指一个骨架同时可以播放多个动画。例如下面的代码,可以让角色同时播放 walk 和 fall 的动画。

//设置别名
var dragonBones = Tiny.DragonBones;
armatureDisplay.animation.fadeIn('walk', 0, -1, 0, 0, 'UPPER_BODY_GROUP', dragonBones.Animation.SAME_GROUP);
armatureDisplay.animation.fadeIn('fall', 0, -1, 0, 0, 'LOWER_BODY_GROUP', dragonBones.Animation.SAME_GROUP);
6、调试骨骼

参考 demo/debugdraw.html

armatureDisplay.debugDraw = true;
