Hey everyone, I was building this tool for my internal use, and thought I would spin it off as a full tool and sell it in case it was useful for anyone else. I wanted something extremely fast and with good CLI integration, and something very portable as well. So that's what I built, in Zig with a Dear ImGui interface.

I am mostly focusing on code-first environments right now, like LibGDX. This is the exporter I use for my own projects in Haxe/Heaps.io, as it uses the LibGDX format.

Anyway, thanks for checking it out. Let me know what you think.

I'm struggling to find a way to warp/bend images like shown above.

(the fish shown arent exactly the same but you get the idea)

I believe that it's something to do with Meshes but I can't figure it out for the life of me.

Ufo shooting is most fun if the flying crafts really act like a working machine:

UFOs are built from destructible pieces
A UFO isn't one solid model — it's assembled from individual structural pieces (engines, hull plates, weapon mounts, etc.). Every hit can knock off one specific piece. Shoot off an engine and the ship actually loses lift, since fewer engines means less thrust holding it up.

Shields absorb the first hits
Each UFO has a shield worth half its total health. While the shield holds, incoming shots just bounce off an invisible barrier around the ship — the hull takes no damage. Only once the shield is depleted do shots start actually blowing pieces off.

Shoot off the weapon, and it goes quiet
If the ship's weapon mount gets shot away, the UFO loses the ability to fire back — it'd still fly and maneuver, just harmlessly, until it's finished off or crashes.

Shoot the reactor and it's a chain reaction
UFOs carry a reactor block as part of their structure. Destroy it and it doesn't just disappear — it triggers a proper chain-reaction explosion, chewing through a chunk of the surrounding hull with a real physical shockwave that scatters debris outward. It's one of the most satisfying ways to finish a ship off.

How a UFO goes down
A UFO starts crashing if its hull takes lethal damage, it slams into the ground, or it gets stuck on the ground too long without managing to take off again. The moment it starts crashing, its shield is gone for good. It tumbles and settles for a bit before being counted as fully crashed and landed.

A crash doesn't always mean the fight's over
If the pilot survives the crash, they are able to climb out of the wreck and keep fighting on foot — a downed UFO isn't necessarily a dead threat, just a different one.

Pilots and crew
UFOs can carry a pilot/crew in designated seats. If the crew is wiped out mid-flight, the ship is tracked as "unpiloted" and can keep drifting crewless, but eventually the engines will stop and it will fall.

What is in the full video:
-scavenging alien tech from the fallen ufos
-driving a jeep and using it as a weapon
-upgrading the cannon
-boss fight

How do you like the air defence in this game? How do you think it could be improved?

Hello! I've been working on a open world RPG named Seven Stardust. I've recently been trying to improve the visual quality of my game, and part of that is shaders.

I've had an issue where my music and shaders suddenly change when switching areas and it's a bit jarring. Thankfully, I was able to make a system to blend shaders between different areas. My game does not have complex shaders, it's just a hue change.

However, because of these simple shaders, I'm able to blend Vector3 variables and pass them into my GLSL in order to change hues dynamically. Some of the code I used to get this working is below.

I hope this helps some people out with their games, and have a wonderful day!

i there    private final Vector3 startColor = new Vector3(1f, 1f, 1f);
    private final Vector3 targetColor = new Vector3(1f, 1f, 1f);
    private final Vector3 activeColor = new Vector3(1f, 1f, 1f);
    private float fadeTimer = 0.0f;
    private final float FADE_DURATION = 1.5f;

    public void update(GameScreen game) {
        String mapArea = game.mapSystem.area != null ? game.mapSystem.area : "";

        if (!mapArea.equals(currentArea)) {
            Gdx.app.log("ShaderSystem", "Area shifted to: " + mapArea);
            currentArea = mapArea;

            startColor.set(activeColor);
            targetColor.set(getColorByAreaName(currentArea));
            fadeTimer = 0.0f;
        }

        if (fadeTimer < FADE_DURATION) {
            fadeTimer += Gdx.graphics.getDeltaTime();
            if (fadeTimer > FADE_DURATION) {
                fadeTimer = FADE_DURATION;
            }

            float alpha = fadeTimer / FADE_DURATION;
            activeColor.x = MathUtils.lerp(startColor.x, targetColor.x, alpha);
            activeColor.y = MathUtils.lerp(startColor.y, targetColor.y, alpha);
            activeColor.z = MathUtils.lerp(startColor.z, targetColor.z, alpha);
        }
    }
    /* After this you can pass ActiveColor into your frag shader, Which would change
    the pixels to this color. The code might not work, I kinda just pulled it out of
    my shader system, but that's the general gist of blending. */

Game Title: AgroTycoon

Playable Link: https://ushurileo.itch.io/agro-tycoon (It is playable in the browser but the desktop version "v0.3.1" is more stable)

Platform: Desktop (For now, already have a mobile version but it is unstable)

Description: In this management simulator with an isometric pixel art aesthetic, you aren't just a farmer—you are the CEO of your own operation. Start with a modest plot of land, invest your initial capital wisely, and transform a small crop field into a true agribusiness powerhouse. (I have animals in the roadmap to the game, so it is not just a farming with machines game)

Free to Play Status:

• [x] Free to play
• [ ] Demo/Key available
• [ ] Paid (Allowed only on Tuesdays with [TT] in the title)

Involvement: Marketing, development, asset designer, sound designer, artist, CEO, intern, cleaner and capsule artist.

Yes, creating UI like HUDs and menus for your LibGDX games is simple now.

Modern UI tooling has finally arrived.

Thanks to the feedback from ProGencel on GitHub, I was able to improve the app even further. Although this version is still labeled as beta, it’s already quite stable and usable.

Would love to hear your feedback!

I've been working on my game a lot and I added this rainbow shader to the first area. I'm new to shaders, so while I do like it, I don't know if it would actually be good enough for a game.
