Builtin types

bevy_scriptum provides following types that can be used in Lua:

• Vec3
• BevyEntity

Vec3

Constructor

Vec3(x: number, y: number, z: number)

Properties

• x: number
• y: number
• z: number

Example Lua usage

my_vec = Vec3(1, 2, 3)
set_translation(entity, my_vec)

Example Rust usage

extern crate bevy;
extern crate bevy_scriptum;

use bevy::prelude::*;
use bevy_scriptum::prelude::*;
use bevy_scriptum::runtimes::lua::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_scripting::<LuaRuntime>(|runtime| {
             runtime.add_function(String::from("set_translation"), set_translation);
        })
        .run();
}

fn set_translation(
    In((entity, translation)): In<(BevyEntity, BevyVec3)>,
    mut entities: Query<&mut Transform>,
) {
    let mut transform = entities.get_mut(entity.0).unwrap();
    transform.translation = translation.0;
}

BevyEntity

Constructor

None - instances can only be acquired by using built-in entity global variable.

Properties

• index: integer

Example Lua usage

print(entity.index)
pass_to_rust(entity)

Example Rust usage

extern crate bevy;
extern crate bevy_scriptum;

use bevy::prelude::*;
use bevy_scriptum::prelude::*;
use bevy_scriptum::runtimes::lua::prelude::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_scripting::<LuaRuntime>(|runtime| {
             runtime.add_function(String::from("pass_to_rust"), |In((entity,)): In<(BevyEntity,)>| {
               println!("pass_to_rust called with entity: {:?}", entity);
             });
        })
        .run();
}
