Finishing up ============ We have now completed all the functionality for our game. Below are some remaining steps to add a bit more "juice" to improve the game experience. Feel free to expand the gameplay with your own ideas. Background ~~~~~~~~~~ The default gray background is not very appealing, so let's change its color. One way to do this is to use a `ColorRect` node. Make it the first node under `Main` so that it will be drawn behind the other nodes. `ColorRect` only has one property: `Color`. Choose a color you like and select "Layout" -> "Full Rect" so that it covers the screen. You could also add a background image, if you have one, by using a `TextureRect` node instead. Sound effects ~~~~~~~~~~~~~ Sound and music can be the single most effective way to add appeal to the game experience. In your game assets folder, you have two sound files: "House In a Forest Loop.ogg" for background music, and "gameover.wav" for when the player loses. Add two `AudioStreamPlayer` nodes as children of `Main`. Name one of them `Music` and the other `DeathSound`. On each one, click on the `Stream` property, select "Load", and choose the corresponding audio file. To play the music, add `$Music.play()` in the `new_game()` function and `$Music.stop()` in the `game_over()` function. Finally, add `$DeathSound.play()` in the `game_over()` function. Keyboard shortcut ~~~~~~~~~~~~~~~~~ Since the game is played with keyboard controls, it would be convenient if we could also start the game by pressing a key on the keyboard. We can do this with the "Shortcut" property of the `Button` node. In a previous lesson, we created four input actions to move the character. We will create a similar input action to map to the start button. Select "Project" -> "Project Settings" and then click on the "Input Map" tab. In the same way you created the movement input actions, create a new input action called `start_game` and add a key mapping for the :kbd:`Enter` key. In the `HUD` scene, select the `StartButton` and find its *Shortcut* property in the Inspector. Select "New Shortcut" and click on the "Shortcut" item. A second *Shortcut* property will appear. Select "New InputEventAction" and click the new "InputEventAction". Finally, in the *Action* property, type the name `start_game`. ![](img/start_button_shortcut.png) Now when the start button appears, you can either click it or press :kbd:`Enter` to start the game. And with that, you completed your first 2D game in Godot. ![](img/dodge_preview.gif) You got to make a player-controlled character, enemies that spawn randomly around the game board, count the score, implement a game over and replay, user interface, sounds, and more. Congratulations! There's still much to learn, but you can take a moment to appreciate what you achieved. And when you're ready, you can move on to `doc_your_first_3d_game` to learn to create a complete 3D game from scratch, in Godot.
