PSD文件生成Unity预设

流程：

1.确保psd的单位是像素

2.PS里面选择文件->脚本->浏览，然后选择脚本changePSD.jsx

3.将生成的xml文件放到Sublime Text，选择文件->设置文件编码->UTF-8，保存

4.打开Unity，Hierarchy界面创建新的Panel，选中Panel，选中Assets->UI工具->生成预设prefab->选中上面的xml文件，生成

生成规则

生成规则是根据显示的图层生成的，所以不需要生成的都设置为不可见

图集目录命名规范

Assets\Artist\Atlas\统一放在这个目录下，并且图集文件夹名字和图集名字要一致

例子Assets\Artist\Atlas\background\background.prefab

字集目录规范

字集的预设直接生成在这个目录：Assets\Arist\Font

例子：Assets\Arist\Font\Font_Powerup.prefab

Unity命名规则

按钮图标 btn_xxx

图标 icon_xxx

面板 panel_xxx

背景 bg_xxx

文字 txt_xxx

勾选框 checkBtn_xxx

某个子item item_xxx

命名规则

字体：UILabel+24+simhei+txt_xxx（UILabel为控件名必填，24为字体大小，simhei为字集名，txt_xxx为unity命名）

或只命unity名字体：txt_xxx

艺术字：UINGUILabel+24+font_fight_blue2+txt_xxx(UINGUILabel为控件名，24为字体大小，font_fight_blue2为资源名，txt_xxx为unity命名)

Sprite：UISprite+kongjian+icon_lock+icon_xxx(UISprite为控件名，kongjian为图集名，icon_lock为资源名，icon_xxx为unity命名)

Texutre：UITexture+Head+1001+bg_xxx（UITexture为控件名，Head为文件夹名字，1001为资源名，bg_xxx为unity命名）

changePSD.jsx

var doc = app.activeDocument
var out = "" //创建储存遍历结果的变量
var depth = 0;
var root = new XML("<root/>");getLayer(doc.layers, 0)//变量图层
var xml = root.toXMLString();
xml = xml.replace(/'/g,'"');
var file = new File();
var fileNew = file.saveDlg("Save new file", "*.xml");
if (fileNew)
{fileNew.open("w");xml = xml.replace(/
/g, "\n"); //这一步是为了替换换行符号fileNew.write(xml);fileNew.close();
}function getLayers(layers, count)
{for(var i=0; i<layers.length; i++){if(!layers[i].visible) // 只处理显示可见的{continue;}if(layers[i].typename == "LayerSet") // 判断是否为图层组{var group = new XML("<group/>");group.@name = layers[i].name;group.@parent = layers[i].parent.name;group.@opacity = layers[i].opacity.toFixed(0);root.appendChild(group);getLayers(layers[i].layers, count+1);//递归}else{var layer = new XML("<layer/>");layer.@name = layers[i].name;layer.@index = depth;layer.@kind = layers[i].kind;layer.@parent = layers[i].parent.name;layer.@bounds = layers[i].bounds;layer.@opacity = layers[i].opacity.toFixed(0);if(layers[i].kind == LayerKind.TEXT){layer.@r = layers[i].textItem.color.rgb.red.toFixed(0);layer.@g = layers[i].textItem.color.rgb.green.toFixed(0);layer.@b = layers[i].textItem.color.rgb.blue.toFixed(0);layer.@txt = layers[i].textItem.contents;layer.@font = layers[i].textItem.font;}if(layers[i].kind == LayerKind.SMARTOBJECT){layer.@a = layers[i].rotate;}root.appendChild(layer);depth++;}}
