UE4開發插件流程
1. 直接從Editor中生成一個空的插件模板
2. 關掉vs,右鍵生成一下工程文件,把Plugins掃進去
3. 打(dǎ)開解(jiě)決方案開始編寫插件
首先把插件的配置文TestPlugin.uplugin件改一下(被這個坑了兩天)
這個LoadingPhase的值默認(rèn)為Default,必須修改為PreDefault,不然重(chóng)啟Editor會報關聯不上插件源碼的錯誤(wù),切記(jì)!
修改編譯模塊配置(zhì)TestPlugin.Build.cs文件,c#文件
詳細代碼(mǎ),裏麵有注釋
using UnrealBuildTool;
using System.IO; //路徑獲取需要用(yòng)到IO
public class TestPlugin : ModuleRules
{
private string ModulePath //當前TestPlugin.Build.cs文(wén)件所在的路徑
{
get { return Path.GetDirectoryName(RulesCompiler.GetModuleFilename(this.GetType().Name)); }
}
private string ThirdPartyPath //這個插件引用的第三方庫(kù)的目錄
{
get { return Path.GetFullPath(Path.Combine(ModulePath, "../../ThirdParty/")); }
}
private string MyTestLibPath //第三方(fāng)庫MyTestLib的目錄
{
get { return Path.GetFullPath(Path.Combine(ThirdPartyPath, "MyTestLib")); }
}
public TestPlugin(TargetInfo Target)
{
PublicIncludePaths.AddRange( //公有文件搜索路徑
new string[] {
"TestPlugin/Public"
// ... add public include paths required here ...
}
);
PrivateIncludePaths.AddRange(
new string[] {
"TestPlugin/Private" //私有(yǒu)文件搜索路徑
// ... add other private include paths required here ...
}
);
PublicDependencyModuleNames.AddRange(
new string[]
{
"Core"
// ... add other public dependencies that you statically link with here ...
}
);
PrivateDependencyModuleNames.AddRange(
new string[]
{
"CoreUObject",
"Engine",
"Slate",
"SlateCore",
// ... add private dependencies that you statically link with here ...
}
);
DynamicallyLoadedModuleNames.AddRange(
new string[]
{
// ... add any modules that your module loads dynamically here ...
}
);
LoadThirdPartyLib(Target); //加載第三方庫
}
public bool LoadThirdPartyLib(TargetInfo Target)
{
bool isLibrarySupported = false;
if ((Target.Platform == UnrealTargetPlatform.Win64) || (Target.Platform == UnrealTargetPlatform.Win32))//平台判斷
{
isLibrarySupported = true;
System.Console.WriteLine("----- isLibrarySupported true");
string PlatformSubPath = (Target.Platform == UnrealTargetPlatform.Win64) ? "Win64" : "Win32";
string LibrariesPath = Path.Combine(MyTestLibPath, "Lib");
PublicAdditionalLibraries.Add(Path.Combine(LibrariesPath, PlatformSubPath, "TestLib.lib"));//加(jiā)載第三方靜態庫.lib
}
if (isLibrarySupported) //成功加載庫的情況下,包(bāo)含第三方庫的頭文件
{
// Include path
System.Console.WriteLine("----- PublicIncludePaths.Add true");
PublicIncludePaths.Add(Path.Combine(MyTestLibPath, "Include"));
}
return isLibrarySupported;
}
}
寫個自定(dìng)義的char – TestChar,繼承(chéng)自Character
先看下文件結構(gòu),需要藍圖可見的必須丟到Public下
先修改預編譯頭文件TestPluginPrivatePCH.h,必(bì)須包(bāo)含CoreUObject,不然編譯不過,切記!
#include "TestPlugin.h"
// UObject core#include "CoreUObject.h" //默認(rèn)是不(bú)含這個的
// Actor based classes
#include "GameFramework/Character.h" //包插件中所有用的的引(yǐn)擎(qíng)類都(dōu)丟到這裏(lǐ)來
頭文件,正常編寫自定義(yì)的類一樣
#pragma once
#include "GameFramework/Character.h"
#include "TestChar.generated.h"
UCLASS()
class ATestChar : public ACharacter
{
GENERATED_BODY()
public:
// Sets default values for this character\'s properties
ATestChar();
UPROPERTY(EditAnywhere, Category = "Test Char")
int32 mAge;
UPROPERTY(EditAnywhere, Category = "Test Char")
FString mName;
};
//cpp文件,包含的是預編譯文件和(hé)類的頭文件(jiàn)
#include "TestPluginPrivatePCH.h"
#include "TestChar.h"
#include "TestLib.h" //引入的第三方庫的頭文件
ATestChar::ATestChar() : Super()
{
mAge = myPrint("hello world", 123); //第三方庫中的方法
mName = "yangx";
}
第三方(fāng)庫打成(chéng)了一(yī)個靜態庫TestLib.lib
TestLib.h
#ifndef __TEST_LIB_H__
#define __TEST_LIB_H__
#include
#include
int myPrint(std::string _name, int _age);
#endif
//TestLib.cpp
#include "TestLib.h"
int myPrint(std::string _name, int _age)
{
return _age + 1000;
}
4. 編譯運行,在(zài)Editor中create一(yī)個Blueprint繼承自這個TestChar類
5. 拖到(dào)場景運行(háng)遊戲
