Procedural Terrain Generation pt.2

    So yesterday I implemented the most sloppy multi-layer noise system ever created by man. I tried to stick to the tutorial as much as I could, but some things just wouldn't cooperate.
    The main thing that Unreal didn't agree with was a nested class. The basic idea behind the need for the nested class was it was to be a container for some modifiers to the noise settings. The problem was that I was unable to make an array of this class into a UPROPERTY. This is because, quite understandably, UPROPERTY's require the variable type to be derived from an unreal class, struct, or enum. But these things require special things that a nested class is unable to have (eg. GENERATED_BODY(), .generated.h). To get around this I just created another data asset that would hold the same information. The problem with this is that is adds lots of unnecessary clutter to the details panel in Unreal. I will continue looking for a fix for this, but for now it works so whatever.
    The rest of the tutorial went well with almost no hiccups. The only other major problem I found was with the layered noise that I had implemented last time. The problem was that the sublayers of noise were supposed to have a higher frequency to add more detail, but they weren't. The system was generating the same noise pattern every time, resulting in really smooth but exaggerated terrain features. I will work on changing this and possibly giving the sublayers an offset to make it feel more random from the base generated noise.

A New Chapter

     This week has presented the biggest change probably since the release of Mini Solar System; I was offered a full-time position as a junior programmer at Studio 369 which I was happy to accept. I start on Monday and I couldn't be more excited to work with the team there! However, this did mean though that my priorities shifted quite instantaneously. I went from working full-time on "RPG_Game" to preparing for this new job. This mainly meant getting up to speed on networking as that is the one area of Unreal Engine I feel I have a lack of knowledge in (I'm already proficient in UI, AI, gameplay, materials, and general backend work), and since 369's specialty is networking I figured I would come prepared. I did do a little work on "RPG_Game" but it was minimal just to tie up some loose ends. Unreal's Multiplayer Framework      As explained by the Unreal Engine documentation, "multiplayer programming [is] inherently more complex than programmin...

Progress Update #2

Star Properties     It seems to have become tradition that whenever I set out to do something that I think will be easy, it ends up being the opposite. Making properties for the stars was no different. There were two main parts to this process. Making changes to variables apply to the material, and making those changes affect the lighting of the planets.     Making the variables apply to the material was not that hard as I had done that before. It just ended up being a time consuming process to do for all the properties. All that I had to do was implement a  PostEditChangeProperty for every property and set a vector or scalar parameter value for each on a UMaterialInstanceDynamic. Here's what that looks like for radius and mass: void AStar ::PostEditChangeProperty( FPropertyChangedEvent & PropertyChangedEvent) { if (PropertyChangedEvent.Property != nullptr ) { const FName PropertyName(PropertyChangedEvent.Property->GetName()); if...

Planet Coloring pt.1.5     Within the past day, I have managed to add full color to the planets. Although it took more time and effort than I would have expected, I am happy with the result.     The biggest challenge I had to overcome was getting a color gradient. In Unity, there is simply a variable type 'Gradient' that gives you a nice small UI to pick colors and can be converted to a 2D texture that can be used in the shader graph. What's wrong with that? Well Unreal decided that wouldn't be complicated enough.     So after a bit of searching online for "ue4 gradient" or "color gradient ue4", I came across this forum answer that introduced me to curves. So instead of having variable type 'Gradient' you would have ' UCurveLinearColor' because that's so much more intuitive. Then you will have to create a Curve of type LinearColor in the content browser. Now once you assign assign that variable in the details panel, and open the ...
