Unity生成素材,运行时加载到游戏中

此文简单的说明下,在unity编辑器中导出材质(Material),并在运行时使用WWW加载到游戏中.

1.从editor中先导出(材质)资源文件.

#pragma strict
#pragma implicit
#pragma downcast
import System.Collections.Generic;
//////////////////////////////////////////////////////
///场景,组件,导出工具.
//////////////////////////////////////////////////////
/** 上次场景保存的名字 */
private static var lastSceneName:String = "";
/** 常量 */
private static var strSaveScene:String = "指定保存场景的位置";
private static var lastDirPath:String = "";
/** 导出的场景后缀 */
private static var strUnity3d:String = "unity3d";
/** 场景后缀 */
private static var strSceneExtendName:String = "unity";
private static var strSceneExportError:String = "no scene file!";
private static var strExport:String = "导出";
/**
	导出场景 
*/
@MenuItem("Level4/Export/ExportScene")
static function BuildStreaedScene(){
	var pathList:List.<String> = new List.<String>();
	var objs:Object[] = Selection.GetFiltered(typeof(Object),SelectionMode.DeepAssets);
	for(var obj:UnityEngine.Object in objs){
		var path:String = AssetDatabase.GetAssetPath(obj);
		if(path.Contains(strSceneExtendName)){
			pathList.Add(path);
		}
	}
	if(pathList.Count > 0){
		var locationPath:String = EditorUtility.SaveFilePanel(strSaveScene,"",lastSceneName,strUnity3d);
		if(!String.IsNullOrEmpty(locationPath)){
			BuildPipeline.BuildStreamedSceneAssetBundle(pathList.ToArray(),locationPath,BuildTarget.WebPlayer);
			OpenDir(locationPath);
		}
	}else{
		Debug.Log(strSceneExportError);
	}
	pathList.Clear();
	pathList = null;
}
/**
	导出素材
*/
@MenuItem("Level4/Export/ExportResource")
static function ExportResource(){
	if(Selection.activeObject){
		var srcName:String = Selection.activeObject.name;
		var path:String = EditorUtility.SaveFilePanel(strExport,"",srcName,strUnity3d);
		if(path.Length != 0){
			BuildPipeline.BuildAssetBundle(Selection.activeObject,Selection.objects,path);
		}
	}else{
		Debug.Log("Project中选中要导出的物体.");
	}
}
/**
	导出素材和素材依赖
*/
@MenuItem("Level4/Export/ExportResource Track Dependence(multi2one)")
static function ExportResourceTrack(){
	if(Selection.activeObject){
		var srcName:String = Selection.activeObject.name;
		lastDirPath = PlayerPrefs.GetString("lastDirPath","");
		var path:String = EditorUtility.SaveFilePanel(strExport,lastDirPath,srcName,strUnity3d);
		if(path){
			PlayerPrefs.SetString("lastDirPath",System.IO.Directory.GetParent(path).ToString());
			
			var objs:Object[] = Selection.GetFiltered(Object,SelectionMode.DeepAssets);
			BuildPipeline.BuildAssetBundle(Selection.activeObject,objs,path,BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets);
			Selection.objects = objs;
			//打开导出的目录
			OpenDir(path);
		}
	}else{
		Debug.Log("Project中选中要导出的物体.");
	}
}

@MenuItem("Level4/Export/ExportResources Track Dependence(one by one)")
static function ExportResourcesTrack(){
	var objs:UnityEngine.Object[] = Selection.objects;
	var path:String = null;
	for(var obj:UnityEngine.Object in objs){
		var srcName:String = obj.name;
		lastDirPath = PlayerPrefs.GetString("lastDirPath","");
		path = EditorUtility.SaveFilePanel(strExport,lastDirPath,srcName,strUnity3d);
		if(path){
			PlayerPrefs.SetString("lastDirPath",System.IO.Directory.GetParent(path).ToString());
			BuildPipeline.BuildAssetBundle(obj,null,path,BuildAssetBundleOptions.CollectDependencies|BuildAssetBundleOptions.CompleteAssets);
			Selection.activeObject = obj;
		}else{
			//全部取消.
			break;
		}
	}
	if(path){
		OpenDir(path);
	}
}

/**
	打开目录
*/
static function OpenDir(path:String){
	if(EditorUtility.DisplayDialog("注意","打开刚才导出文件的目录?","是","否")){
		path = System.IO.Directory.GetParent(path).ToString();
		System.Diagnostics.Process.Start(path);
	}
}

2.使用WWW类,在运行期加载导出的材质文件.

	function LoadMat(url:String){
		Debug.Log(url);
		var www:WWW = WWW(url);
		yield www;
		// Debug.Log(typeof www.assetBundle.mainAsset);
		
		var mat:Material = www.assetBundle.mainAsset; //这里获取下载的材质.可直接应用到模型.
	}

其余的素材资源,如果模型fbx,声音等.导出后在运行时加载到游戏中的方式类似哦.
导出场景(关卡)的方式则不同:
