Unity-Tween 插件比较

1、GoKit

免费开源

AssetStore：https://www.assetstore.unity3d.com/en/#!/content/3663

下载地址：https://github.com/prime31/GoKit

2、ITween

免费开源

官网：http://itween.pixelplacement.com/index.php

AssetStore：https://www.assetstore.unity3d.com/en/#!/content/84

下载地址：https://github.com/jtothebell/iTween

缺点：

1. 大量使用SendMessage，而SendMessage使用反射，效率不高
2. iTween的参数都是string，你需要自己去拼一个Hashtable，去记字符串，不人性化！每次写都要去它的官网上去查字符串怎么拼，挺蛋疼的！

3、LeanTween

免费开源

AssetStore：https://www.assetstore.unity3d.com/en/#!/content/3595

下载地址：https://github.com/dentedpixel/LeanTween

优点：貌似比Hotween和Itween性能好，快！参考：http://dentedpixel.com/developer-diary/leantween-speed-comparison-to-itween/

4、Hotween

免费开源

官网：http://hotween.demigiant.com/

AssetStore：https://www.assetstore.unity3d.com/en/#!/content/3311

5、DOTween

 这是Hotween官网出的，速度超过4倍更快,更高效,大量的新功能

 Comparison with other engines

If you want, you can download the test package I used (oops sorry, I'll put it up there when I get into beta, otherwise I should update it every hour - but you can still get the most recent one from DOTween's Google Code area).

All these tests were done from a build, since some of these tween engines (DOTween, HOTween and GoKit) do additional stuff while in the Editor to show editor-only debug informations, and thus testing them outside the editor, where it counts, seemed more fair.

To keep the test accurate download the latest versions of all engines and replace the old ones (the ones used here are from July/August 2014).

Generic floats

You'll find more tests for the tween of generic floats because GoKit and iTween couldn't tween as many as the other engines, but I still wanted to show high-level results.

64,000 generic floats in a loop

	DOTween	HOTween	LeanTween	GoKit	iTween
Average FPS	124 FPS	25 FPS	102 FPS	freezes	freezes
Startup time	76 MS	332 MS	34 MS	freezes	freezes

16,000 generic floats in a loop

	DOTween	HOTween	LeanTween	GoKit	iTween
Average FPS	412 FPS	115 FPS	389 FPS	387 FPS	freezes
Startup time	14 MS	74 MS	7 MS	47,432 MS	freezes

2,000 generic floats in a loop

	DOTween	HOTween	LeanTween	GoKit	iTween
Average FPS	1091 FPS	888 FPS	1050 FPS	998 FPS	3 FPS
Startup time	2 MS	11 MS	1 MS	6,258 MS	240 MS

Transforms

4,000 transforms looping around

 

	DOTween	HOTween	LeanTween	GoKit	iTween
Average FPS	68 FPS	63 FPS	68 FPS	65 FPS	38 FPS
Startup time	5 MS	30 MS	3 MS	130 MS	229 MS

 

实现人物沿四个点移动，实现这同一效果，代码分别为：

 

 

  Dotween

  LeanTween

  GoKit

  Hotween

  Itween

总结：

从以上分析，Dotween和Leantween效率比较好，但是从代码角度看，Dotween代码可读性强，体现了面向对象的思想，而Leantween仍然要死记字符串！
