UnrealEngine:加载

静态加载

ConstructorHelpers::FClassFinder() FObjectFinder()

在构造函数中完成加载，无法改变路径

 

UTexture2D* texture;

static ConstructorHelpers::FObjectFinder<UTexture2D> Texture(TEXT("/Game/StarterContent/Textures/T_Spark_Core"));

if (Texture.Successed())

{

　　texture = Texture.Object;

}

 

 

动态加载

LoadObject()　　StaticLoadObject()

LoadObject()用来加载非蓝图资源，如贴图

LoadClass()用来加载蓝图并获取蓝图类

UMaterial* mt = LoadObject<UMaterial>(nullptr, TEXT("/Game/Map/Materials/grass.grass"));

UMaterial* mt = Cast<UMaterial>(StaticLoadObject(UMaterial::StaticClass(), nullotrm, TEXT("/Game/Map/Materials/grass.grass")))
