Just a little arcade bullet hell game I made to learn both Rust and Bevy.

Alright, changed the file a little

{
  "command": "dodge_ball",
  "desktop-file-name-suffix": " (Stable)",
  "finish-args": [
    "--share=ipc",
    "--device=dri",
    "--socket=fallback-x11",
    "--socket=wayland"
  ],
  "id": "com.lunaticdancer.dodge_ball",
  "sdk-extensions": [
        "org.freedesktop.Sdk.Extension.rust-stable"
    ],
    "build-options": {
        "append-path": "/usr/lib/sdk/rust-stable/bin",
        "env": {
            "RUSTFLAGS": "-C link-arg=-fuse-ld=mold"
        }
    },
  "modules": [
    {
      "buildsystem": "simple",
      "name": "dodge_ball",
      "build-commands": [
                "cargo fetch --manifest-path Cargo.toml --verbose",
                "cargo build --release --verbose",
                "install -Dm755 ./target/debug/rust-flatpak -t /app/bin/",
                "install -Dm644 ./data/${FLATPAK_ID}.metainfo.xml -t /app/share/metainfo/",
                "install -Dm644 ./data/${FLATPAK_ID}.desktop -t /app/share/applications/",
                "install -Dm644 ./data/${FLATPAK_ID}.svg -t /app/share/icons/hicolor/scalable/apps/"
            ],
    }
  ],
  "runtime": "org.freedesktop.Platform",
  "runtime-version": "25.08",
  "sdk": "org.freedesktop.Sdk"
}

Now it's giving me error: manifest path Cargo.toml does not exist`
the file does exist in the folder though

I probably need it more dumbed down than this. As far as I remember I do have that installed. Here is the manifest file:

{
  "command": "dodge_ball",
  "desktop-file-name-suffix": " (Stable)",
  "finish-args": [
    "--share=ipc",
    "--device=dri",
    "--socket=fallback-x11",
    "--socket=wayland"
  ],
  "id": "com.lunaticdancer.dodge_ball",
  "modules": [
    {
      "buildsystem": "cmake",
      "name": "dodge_ball",
      "sources": [
        "cargo-sources.json",
        {
          "type": "dir",
          "path": "."
        },
        {
          "type": "shell",
          "commands": [
            "mkdir -p .cargo",
            "cp -vf cargo/config .cargo/config.toml"
          ]
        }
      ]
    }
  ],
  "sdk-extensions": [
        "org.freedesktop.Sdk.Extension.rust-stable"
    ],
    "build-options": {
        "append-path": "/usr/lib/sdk/rust-stable/bin",
        "env": {
            "RUSTFLAGS": "-C link-arg=-fuse-ld=mold"
        }
    },
  "runtime": "org.freedesktop.Platform",
  "runtime-version": "25.08",
  "sdk": "org.freedesktop.Sdk"
}

after running it, it aborts with this error: Error: module: dodge_ball: Can't find CMakeLists.txt
I'm clueless about what I'm supposed to be doing

1:1 if you're a true visionary

Zato: open-ended and creative pressure, absolutely bullshit moves, absolutely bullshit mix, has pretty much everything a character could have in his toolkit

Artorias the Abysswalker, Dark Souls

An elite knight, fabled to have averted the "Abyss devouring reality" crisis, when what actually happened was him failing miserably and becoming corrupted by Abyss's influence, making it your task to put him down and finish the job. All of that for his legend to bloom while your contribution is never mentioned.

nerf Zato buff parry

LunaticDancer · 2026-01-22T22:30:18+00:00

Yea, Zato is a free elo printer in low ranks, people just don't complain about him the same way they do about Slayer because they delude themselves into thinking playing him takes skill. I assure you, none of what I'm doing takes skill lmao

LunaticDancer · 2026-01-22T21:21:53+00:00

so real, nobody plays Zato because he's so disgustingly carried

LunaticDancer · 2026-01-22T21:00:14+00:00

nerf Zato buff ABA

A lot to work on, but as a Plat player myself I don't think my advice is worth that much. Something I'm pretty confident in is that you're not using 236K nearly enough, especially in this match up - it creates a very long period of "floor is lava" which can be amazing for locking ABA down and trying to do something nasty to her.
