UE 踩坑记录

1. UE引擎崩溃

报错: UObject() constructor called but it's not the object that's currently being constructed with NewObject. Maybe you are trying to construct it on the stack, which is not supported.

原因: UObject不能直接调用构造函数. 在声明时应该使用指针, 然后再用CreateDefaultSubobject来创建

错误示例: 

UDemoObject DemoObject;

正确示例: 

UDemoObject* DemoObject;

DemoObject = CreateDefaultSubobject<UDemoObject>(TEXT("UDemoObject"));
