Text Editor / IDE

This page contains tips for different text editors and IDEs.

Bevy is, for the most part, like any other Rust project. If your editor/IDE is set up for Rust, that might be all you need. This page contains additional information that may be useful for Bevy specifically.

Please help improve this page by providing suggestions for things to add.

CARGO_MANIFEST_DIR

When running your app/game, Bevy will search for the assets folder in the path specified in the BEVY_ASSET_ROOT or CARGO_MANIFEST_DIR environment variable. This allows cargo run to work correctly from the terminal.

If you are using your editor/IDE to run your project in a non-standard way (say, inside a debugger), you have to be sure to set that correctly.

If this is not set, Bevy will search for assets alongside the executable binary, in the same folder where it is located. This makes things easy for distribution. However, during development, since your executable is located in the target directory where cargo placed it, Bevy will be unable to find the assets.

VSCode

Here is a snippet showing how to create a run configuration for debugging Bevy (with lldb):

(this is for development on Bevy itself, and testing with the breakout example)

(adapt to your needs if using for your project)

{
    "type": "lldb",
    "request": "launch",
    "name": "Debug example 'breakout'",
    "cargo": {
        "args": [
            "build",
            "--example=breakout",
            "--package=bevy"
        ],
        "filter": {
            "name": "breakout",
            "kind": "example"
        }
    },
    "args": [],
    "cwd": "${workspaceFolder}",
    "env": {
        "CARGO_MANIFEST_DIR": "${workspaceFolder}",
    }
}

IntelliJ

When using queries, type information gets lost due to Bevy relying on procedural macros. You can fix this by enabling procedural macro support in the IDE.

1. type Experimental feature in the dialog of the Help | Find Action action
2. enable the features org.rust.cargo.evaluate.build.scripts and org.rust.macros.proc
