Trying to build this on vc++ 2015 but i’m getting this build error:

The following is what the .uplugin file looks like, i tried to change the version number hoping that it would make a different.


{
    "PluginFileVersion" : 1,

    "FriendlyName" : "Simplex Noise",
    "Version" : 1,
    "VersionName" : "1.0.0",
    "CreatedBy" : "DavDad",
    "CreatedByURL" : "https://art-and-code.com/",
    "EngineVersion":"4.17",
    "Description" : "SimplexNoise Blueprint Library to use in Unreal Engine 4",
    "Category" : "ArtAndCodeSuite.SimplexNoise",
    "EnabledByDefault" : true,

    "Modules" :
            
        {
            "Name" : "SimplexNoise",
            "Type" : "Runtime",
            "LoadingPhase" : "PreDefault",
            "WhitelistPlatforms" :  "Win64", "Win32", "Mac" ]
        },


    ]
}

Anyways, any help would be appreciated since i have little experience with the C++ side of UE4

Edit: I fixed it, all i had to do was fix the header order…

The stuff about the build.cs are just warnings, you can (probably) ignore them.

The real error is this one:


 
 SimplexNoiseBPLibrary.cpp(1): error : Expected SimplexNoiseBPLibrary.h to be first header included.

As it says, you could try moving the SimplexNoiseBPLibrary.h to be the first include file in SimplexNoiseBPLibrary.cpp. Though without looking at it and trying to compile it myself I may be missing something.

74

Ok, i got it working by just changing the header order…which is confusing to me since i’ve never had to do that before…

However, i am having issues getting a demo working, I don’t seem to have the same nodes that the OP has, my Simplex Noise 3D only has X Y Z and Return Value as well as the execution pins, but i do not have the rest of the pins on that node…

Also i have no nodes named Planet anything… any ideas? have you had these issues?

75

Edit: Where’s the download for this anyway? I can’t seem to find it on the thread.

TBH I haven’t played with this project at all. I’ll look into it as planet terrain is one of my favorite things ever, and report back. Dunno about a timeframe though, might be a couple of days.

One thing you can do is look at the source and find which nodes it creates directly that way.

he never released anything for his blueprint examples… but the plugin he’s using for the noise generation is here: GitHub - devdad/SimplexNoise: * This is a clean, fast, modern and free Perlin Simplex noise function.All Public Functions are BlueprintCallable so they can be used in every blueprint. From DevDad and Dedicated to you and Unreal Community Use it free for what ever you want I only request that you mention me in the credits for your game in the way that feels most appropriate to you.

77

What is this “different project”. I dont know

78

How are you generating the galaxy map?

79

What about multiplayer and double precision?

80

No double precision here as it would require heavy engine modifications. I’m using Origin Offset for huge planets and whole solar systems.
Multiplayer, yep, planets are generated on the clientside only, so you’d have to take that into account when dealing with physics. The rest is entirely up to you.

81

Hello, I’m just curious is there any progress to this? I’m currently spending like 10 hours a day trying to produce a system in UE4 currently.

Greetings Z-enzyme, News on Simple Procedural Planets - BP only ??? If it’s free, where can I download it ???
If you pay, how much are your procurement of the planet ???
