ue5 小知识点 ue的world type,pie editor game

说明以该命令行模式启动游戏的前提下的两个问题:

1.WITH_EDITOR中的代码会被编译

2.由于没有在编辑器中(即没有打开虚幻编辑器),所以GIsEditor为false

WITH_EDITOR和WITH_EDITORONLY_DATA的区别

在论坛中找到的答案:

复制代码
WITH_EDITORONLY_DATA in headers for wrapping reflected members.
WITH_EDITOR in CPP files for code.. Has nothing to do with reflection.

意思就是:

头文件中使用WITH_EDITORONLY_DATA包装反射的成员。

在CPP文件的代码中使用WITH_EDITOR,与反射无关。

callineditor

cpp 复制代码
	
.h
    UFUNCTION(CallInEditor, Category = "Sky Creator|General")
	void SetEditorTimeOfDay(float NewValue);
	UFUNCTION(CallInEditor, Category = "Sky Creator|General")
	void SetEditorWeatherPreset(USkyCreatorWeatherPreset* NewValue);
	UFUNCTION(CallInEditor, Category = "Sky Creator|General")
	void SetEditorWeatherSettings(FSkyCreatorWeatherSettings NewValue);

.cpp


#define SKYCREATOR_DECLARE_SEQUENCER_SETFUNCTION_ANDUPDATE(MemberType, MemberName) void ASkyCreator::Set##MemberName(MemberType NewValue)\
{\
	if (MemberName != NewValue)\
	{\
		MemberName = NewValue;\
		UpdateSettings();\
	}\
}\

SKYCREATOR_DECLARE_SEQUENCER_SETFUNCTION(float, EditorTimeOfDay);
SKYCREATOR_DECLARE_SEQUENCER_SETFUNCTION_ANDUPDATE(USkyCreatorWeatherPreset*, EditorWeatherPreset);

SKYCREATOR_DECLARE_SEQUENCER_SETFUNCTION(float, SunriseTime);
SKYCREATOR_DECLARE_SEQUENCER_SETFUNCTION(float, SunsetTime);
SKYCREATOR_DECLARE_SEQUENCER_SETFUNCTION(float, SunDawnOffsetTim
