What happend to TargetInfo.Target in 4.19?

NuLL3rr0r · February 6, 2018, 8:37pm

I’m not sure if this is the right place to ask this (for two days tried posting it on UE4 answerhub but it won’t allow me with a weird error).

I used to do this on 4.18 and earlier versions in my Target.cs:



        if (Target.Type == TargetRules.TargetType.Editor) {
            ExtraModuleNames.AddRange(
                new string] {
                    "MyProjectEditor"
                });
        }

Looking at the engine source, it seems that on 4.19 Type property has been removed from TargetInfo and I’m getting the following error:



    ERROR: /path/to/MyProject.Target.cs(23,20) : error CS1061:
Type `UnrealBuildTool.TargetInfo' does not contain a definition for
`Type' and no extension method `Type' of type `UnrealBuildTool.TargetInfo'
could be found. Are you missing an assembly reference?
    ERROR: UnrealBuildTool Exception: Unable to compile source files.

What’s the alternative to check target type on 4.19?

The old Target.cs and Build.cs formats have been deprecated for several builds now - you should have had warnings when compiling in previous versions. They probably pulled the plug at last.

Your best bet is to create a new C++ project from the launcher, and copy it’s Target and Build .cs formats.

NuLL3rr0r · February 7, 2018, 10:16am

In fact, I did create a new C++ project before posting here. But, there is no such a check for target type in the engine templates.

As TheJamsh said, they’ve been deprecated for awhile. You can use the following check to find out if the Target is building the Editor:




if (UEBuildConfiguration.bBuildEditor == true)
{
// Add modules....
}

Thank you so much for the solution. That solves the issue. But, wondering how to check for other build targets besides the editor. Namely, Game, Client, Server, and Program?

I believe you can just do


Type == Editor

now, or similar. No need to grab it from TargetInfo.

How do you get a reference to UEBuildConfiguration though?

Huh? There is no need for this. ProjectEditor.Target.cs builds with editor, Project.Target.cs without.

NuLL3rr0r · February 25, 2018, 10:21am

Inside the your .Target.cs you can do this:



    if (this.bBuildEditor) {
        ...
    }

NuLL3rr0r · February 25, 2018, 10:34am

Well, from my experience it seems the build system won’t work like that. It seems, you have to tell the build system to build editor module or not. I can see this in my build/package logs.

Although, it seems bBuildEditor does not have any effects for me. I used to do this on 4.18 and it worked perfectly:


         if (Target.Type == TargetRules.TargetType.Editor) {             ExtraModuleNames.AddRange(                 new string] {                     "MyProjectEditor"                 });         }

Now if I do this (on both 4.18 and 4.19):



        if (this.bBuildEditor) {
            this.ExtraModuleNames.AddRange(
                new string] {
                    "MyProjectEditor"
                });
        }

It builds fine but, when I try to package my game I’ll get the following errors:

And many more errors like that. Those methods should exist on editor builds. Even on Visual Studio I’ll get those errors, too. If I do just this:



        this.ExtraModuleNames.AddRange(
            new string] {
                "MyProjectEditor"
            });

I won’t get those errors. But it packages the editor module inside my packaged game which obviously is not necessary.

NuLL3rr0r · February 25, 2018, 2:48pm

Well, to my surprise it seems @Zeblote is right. I’m not sure what changed in the recent versions but I did this in my . Target.cs files and it worked perfectly fine:



    public MyProjectTarget(TargetInfo Target) : base(Target)
    {
        this.Type = TargetType.Game;

        this.ExtraModuleNames.AddRange(
            new string] {
                "MyProject"
            });

        this.bEnforceIWYU = true;
        this.bCompileLeanAndMeanUE = true;
        this.bForceEnableRTTI = true;
        this.bForceEnableExceptions = true;
    }

And



    public MyProjectEditorTarget(TargetInfo Target) : base(Target)
    {
        this.Type = TargetType.Editor;

        this.ExtraModuleNames.AddRange(
            new string] {
                "MyProject",
                "MyProjectEditor"
            });

        this.bEnforceIWYU = true;
        this.bCompileLeanAndMeanUE = true;
        this.bForceEnableRTTI = true;
    }

Adding editor module to the game module’s ExtraModuleNames is not necessary anymore. Thus, no check if we are building an editor build.

Now my editor module works inside the editor and it won’t get build for non-editor builds.
