我在上一篇教程中提到，只要你的核心形状到位了，据此调整并创造变体也就相当容易了。（请点击此处阅读本教程第一、第二、第三、第四、第五、第六、第七部分内容）

本篇教程将分享如何制作出更像上篇教程首张《HeliAttack3》截图中的直升飞机。

在此我们将直接采用上篇教程中的直升飞机素材，而非以简单的形状重新开始。

注：你可以通过这个地址下载直升飞机素材[http://2dgameartforprogrammers.blogspot.com.au/2012/09/apache-helicopter.html] 。

直升机1(from gamasutra)

直升机2(from gamasutra)

直升机3(from gamasutra)

注：在输出美术内容的时候要把枪支和导弹分离出来。将它们作为添加到基础形状的分离物体，这种用法会更灵活。

这是两个按比例缩小的直升机样本(from gamasutra)

希望本教程能够启发你快速调整矢量元素，并为游戏创造新资产。（本文为游戏邦/gamerboom.com编译，拒绝任何不保留版权的转载，如需转载请联系：游戏邦）

2D Game Art for Programmers – Apache-style helicopter modifications

by Chris Hildenbrand

In the last post I mentioned that it’s fairly easy to modify the basics and create variations once you have the core shape down. [http://www.gamasutra.com/blogs/ChrisHildenbrand/20120917/177819/2D_Game_Art_for_Programmers__Apachestyle_helicopter.php ]

So as requested by some here is a modification tutorial bringing the Apache more in line with the helicopter used in the HeliAttack3 screengrab at the top of the last post.

Instead of the usual start with a simple shape I take the helicopter from the last tutorial.

Note:

You can download it for free at the bottom of the previous post.[http://2dgameartforprogrammers.blogspot.com.au/2012/09/apache-helicopter.html]

Note:

Keep the guns and missiles separated when exporting your art. Add them as separate objects attached the the base shape in your game engine to allow flexible use (e.g. firing and rotation for aiming).

Here are the two helicopters side by side in the scaled down size.

I hope this shed some light on how quickly you can reuse and modify vector elements and create new assets for you game or illustration needs from existing images.（source：gamasutra）
