Querying Input from a Lua Script

[Jolvera2001]

I'm trying to see how I can query the input of a player from a script. I was thinking maybe I can do something similar to how it's done in rust but it doesn't seem to want to work with the way I'm approaching it. I registered ButtonInput<KeyCode> as a type but it's not really working when fetching it in Lua. I don't think this is the approach at all, but I saw that types like GamepadButton are available so why not be able to query which button or key is currently pressed? For reference, this is my script to test this out

local function handleInput()
    local ButtonKeyCode = world.get_resource(types["ButtonInput<KeyCode>"])
    local keys = types.KeyCode

    if ButtonKeyCode.pressed(keys.KeyW) then
        print("W key pressed")
    end

end

function on_update()
    handleInput()
end

And this is the error I'm getting

Reflection path error: Cannot reflect into opaque type of type: bevy_mod_scripting_bindings::query::ScriptTypeRegistration with string key: `["KeyW"]`
On value: (cannot access value, showing reference) base type: bevy_mod_scripting_bindings::query::ScriptTypeRegistration, of kind: Reflect(bevy_mod_scripting_bindings::query::ScriptTypeRegistration) at path ["KeyW"]

The specific error is from keys.KeyW, before pressed can receive an argument. types.KeyCode is a type registration, not a Lua table containing the enum variants.

BMS exposes enum construction through the global construct function. For a unit variant, the documented form is:

local keyW = construct(types.KeyCode, { variant = "KeyW" })

See constructing arbitrary types and the repository's Lua enum-construction test.

With the resource and its pressed binding available, the call would then look like:

local buttons = world.get_resource(types["ButtonInput<KeyCode>"])
local keyW = construct(types.KeyCode, { variant = "KeyW" })
if buttons:pressed(keyW) then
    print("W key pressed")
end

The colon passes the resource as the method receiver. There are two separate requirements here: registering a type allows reflection, but doesn't by itself expose every Rust method. If the enum construction succeeds and the next error is that pressed is unavailable, check the generated/registered function bindings for ButtonInput<KeyCode> in your BMS version. Also ensure the Bevy input resource exists and the script runs after input updates. The snippet addresses the type-registration/enum-value error you posted; the BMS/Bevy versions and Rust registration code would determine the remaining binding setup.

I am getting an error that says

External error: External error: runtime error: ...f8c6b5b557f\bevy_mod_scripting_lua-0.21.0\src\lib.rs:278:13: attempt to call method 'pressed' (a userdata value)

for that code snippet using buttons:pressed(...)

What folder do generated/registered bindings exist in the project? I might end up finding it eventually but thought I might as well ask
