UE4 JSBSim

　步骤：

　　1.从JSBSim官网下载源码

　　2.将JSBSim编译为静态库（lib,多线程DLL）

　　3.ue4项目根目录建立文件件ThirdParty->JSBSim->include、lib文件夹

　　

 　　4.将JSBSim源码中src文件件拷贝到include文件夹，将生成的lib静态库拷贝到lib文件夹

　　 5.在ue4项目的build.cs文件中定义　　

using UnrealBuildTool;
using System.IO;

public class FlightSimulator : ModuleRules
{
    private string ModulePath
    {
        // get { return Path.GetDirectoryName(RulesCompiler.GetModuleFilename(this.GetType().Name)); }
        get { return ModuleDirectory; }
    }

    private string ThirdPartyPath
    {
        get { return Path.GetFullPath(Path.Combine(ModulePath, "../../ThirdParty/")); }
    }
    private string MyLibPath //第三方库MyTestLib的目录
    {
        get { return Path.GetFullPath(Path.Combine(ThirdPartyPath, "JSBSim")); }
    }

    
    public FlightSimulator(ReadOnlyTargetRules Target) : base(Target)
    {
        //PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
        PrivatePCHHeaderFile = "Public/FlightSimulator.h";

        PublicIncludePaths.AddRange(new string[] {
            "FlightSimulator/Public/Player",
            "FlightSimulator/Public/System",
            "FlightSimulator/Public/System/Radar",
            "FlightSimulator/Public/Weapon",
            "FlightSimulator/Public/Weapon/Missile",
            "FlightSimulator/Public/Effect",
            "FlightSimulator/Public/UI",
            "FlightSimulator/Public/AI",
            "FlightSimulator/Public/Sound",
            "FlightSimulator/Public/Online",
            "FlightSimulator/Public/Flight",
            "FlightSimulator/Public/Flight/Others",
            });

        PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "EasyFM"});

        PrivateDependencyModuleNames.AddRange(new string[] { });



        // Uncomment if you are using Slate UI
        // PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });

        // Uncomment if you are using online features
        // PrivateDependencyModuleNames.Add("OnlineSubsystem");

        // To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true
        LoadThirdPartyLib(Target);

    }
    public bool LoadThirdPartyLib(ReadOnlyTargetRules Target)
    {
        bool isLibrarySupported = false;
        if ((Target.Platform == UnrealTargetPlatform.Win64) || (Target.Platform == UnrealTargetPlatform.Win32))//平台判断
        {
            isLibrarySupported = true;
            System.Console.WriteLine("----- isLibrarySupported true");
            string LibrariesPath = Path.Combine(MyLibPath, "lib");
            PublicAdditionalLibraries.Add(Path.Combine(LibrariesPath, "JSBSim.lib"));//加载第三方静态库.lib
        }

        if (isLibrarySupported) //成功加载库的情况下，包含第三方库的头文件
        {
            // Include path
            System.Console.WriteLine("----- PublicIncludePaths.Add true");
            PublicIncludePaths.Add(Path.Combine(MyLibPath, "include"));
        }
        return isLibrarySupported;
    }

}

　　6.在需要使用的地方#include "../ThirdParty/JSBSim/include/FGFDMExec.h"

　　7.JSBSim依旧会报错，不过不影响使用

　　

 　　8.JSBSim生成静态库一定要是多线程DLL(/MD),否则会报错
