Complete behavior

Back to Java.

Complete the setup and attachment steps, then paste this behavior into the attached script.

class RusticBehavior extends Rustic {
    public static void main(String[] args) throws Exception {
        run((callback, dt) -> {
            if (callback.equals("on_start")) rustic.log("info", "Behavior started");
            if (callback.equals("fixed_update") && rustic.key("KeyW").held) {
                double[] p = rustic.get_translation();
                rustic.set_translation(p[0], p[1], p[2] + dt);
            }
        });
    }
}

The SDK is staged automatically beside the source in an engine temporary directory. You do not install a package, copy the SDK into your game, or write a process loop. Programming > Open Programming Workspace also writes editor support files under .rustic/generated/programming. Regenerate those files after upgrading Rustic. Edit your behavior source, not generated SDK files. Run through Rustic Play so the engine can supply the API and callback state.
