Експортування

Огляд

Тепер, коли у вас є робоча гра, ви, мабуть, хочете поділитися своїм успіхом з іншими. Однак не практично просити своїх друзів завантажити Godot лише для того, щоб вони могли відкрити ваш проєкт. Натомість ви можете експортувати свій проєкт, перетворюючи його у "пакет", який може запускати будь-хто.

The way you export your game depends on what platform you are targeting. In this tutorial, you'll learn how to export the Dodge the Creeps game for a variety of platforms. First, however, we need to make some changes to the way the game works.

Примітка

If you haven't made Dodge the Creeps yourself yet, please read Ваша перша гра before continuing with this tutorial.

Приготування проєкту

In Dodge the Creeps, we used keyboard controls to move the player's character. This is fine if your game is being played on a PC platform, but on a phone or tablet, you need to support touchscreen input. Because a click event can be treated the same as a touch event, we'll convert the game to a click-and-move input style.

By default, Godot emulates mouse input from touch input. That means that if anything is coded to happen on a mouse event, touch will trigger it as well. Godot can also emulate touch input from mouse clicks, which we will need to be able to keep playing our game on our computer after we switch to touch input.

In Project > Project Settings, under Input Devices > Pointing, enable Emulate Touch From Mouse.

We also want to ensure that the game scales consistently on different-sized screens, so in the project settings go to Display, then click on Window. In the Stretch options, set Mode to 2d" and Aspect to keep.

Since we are already in the Window settings, we should also set under Handheld the Orientation to portrait.

Далі нам потрібно модифікувати скрипт Player.gd, щоб змінити метод введення. Ми видалимо керування клавішами та змусимо гравця рухатись до "цілі", встановленої дотиком (або клацанням мишки).

Ось повний скрипт для гравця із коментарями щодо того, що ми змінили:

# Add this variable to hold the clicked position.
var target = Vector2()

func _ready():
    hide()
    screen_size = get_viewport_rect().size

func start(pos):
    position = pos
    # Initial target is the start position.
    target = pos
    show()
    $CollisionShape2D.disabled = false

# Change the target whenever a touch event happens.
func _input(event):
    if event is InputEventScreenTouch and event.pressed:
        target = event.position

func _process(delta):
    var velocity = Vector2()
    # Move towards the target and stop when close.
    if position.distance_to(target) > 10:
        velocity = target - position

# Remove keyboard controls.
#    if Input.is_action_pressed("ui_right"):
#       velocity.x += 1

    if velocity.length() > 0:
        velocity = velocity.normalized() * speed
        $AnimatedSprite.play()
    else:
        $AnimatedSprite.stop()

    position += velocity * delta
    # We still need to clamp the player's position here because on devices that don't
    # match your game's aspect ratio, Godot will try to maintain it as much as possible
    # by creating black borders, if necessary.
    # Without clamp(), the player would be able to move under those borders.
    position.x = clamp(position.x, 0, screen_size.x)
    position.y = clamp(position.y, 0, screen_size.y)

Налаштування головної сцени

The main scene is the one that your game will start in. For this Dodge the Creeps example, in Project -> Project Settings -> Application -> Run, set Main Scene to Main.tscn by clicking the folder icon and selecting it.

Шаблони експорту

To export the project, you need to download the export templates from the http://godotengine.org/download. These templates are optimized versions of the engine without the editor pre-compiled for each platform. You can also download them in Godot by clicking on Editor -> Manage Export Templates:

../../_images/export_template_menu.png

Примітка

If you've downloaded Godot from Steam, export templates are already included. Therefore, you don't need to download them using the Manage Export Templates dialog.

In the window that appears, you can click Download to get the template version that matches your version of Godot.

../../_images/export_template_manager.png

Примітка

Export templates are bound to a specific Godot version. If you upgrade Godot, you must download templates that match the new version.

Export presets

Next, you can configure the export settings by clicking on Project -> Export.

Create a new export preset by clicking Add... and selecting a platform. You can make as many presets as you like with different settings.

../../_images/export_presets_window.png

At the bottom of the window are two buttons. Export PCK/ZIP only creates a packed version of your project's data. This doesn't include an executable so the project can't be run on its own.

The second button, Export Project, creates a complete executable version of your game, such as an .apk for Android or an .exe for Windows.

In the Resources and Features tabs, you can customize how the game is exported for each platform. We can leave those settings alone for now.

Експортування на платформами

У цьому розділі ми розглянемо процес для кожної платформи, включаючи будь-яке додаткове програмне забезпечення, або вимоги, які вам знадобляться.

ПК (Linux/macOS/Windows)

Exporting PC platforms works the same across the three supported operating systems. Open the export window and click Add... to create the preset(s) you want to make. Then click Export Project and choose a name and destination folder. Choose a location outside of your project folder.

Click Save and the engine will build the export files.

Примітка

When exporting for macOS, if you export from a macOS computer, you'll end up with a .dmg file, while using Linux or Windows produces a .zip. In either case, the compressed file contains a macOS .app that you can double-click and run.

Примітка

On Windows, if you want your exported executable to have a different icon than the default one, you need to change it manually. See Зміна іконки програми для Windows.

Android

Порада

Мобільні пристрої оснащені найрізноманітнішими можливостями. У більшості випадків налаштування Godot за замовчуванням спрацюють, але мобільний розвиток іноді є більше мистецтвом, ніж наукою, і вам може знадобитися зробити кілька експериментів та пошукати допомоги, щоб все запрацювало.

Перш ніж експортувати проєкт для Android, потрібно завантажити таке програмне забезпечення:

When you run Android Studio for the first time, click on Configure -> SDK Manager and install Android SDK Platform Tools. This installs the adb command-line tool that Godot uses to communicate with your device.

Далі створіть сховище ключів налагодження, запустивши таку команду в командному рядку вашої системи:

keytool -keyalg RSA -genkeypair -alias androiddebugkey -keypass android -keystore debug.keystore -storepass android -dname "CN=Android Debug,O=Android,C=US" -validity 9999

Клацніть на Редактор -> Параметри редактора в Godot і виберіть розділ Export/Android. Тут вам потрібно встановити шляхи до додатків Android SDK у вашій системі та місце розташування створеного вами сховища ключів.

../../_images/export_editor_android_settings.png

Now you're ready to export. Click on Project -> Export and add a preset for Android (see above). Select the newly added Android preset. Under Options, go to Screen and set Orientation to Portrait. If your game is in landscape mode (i.e. the window width in pixels is greater than the window height), leave this on Landscape.

Click the Export Project button and Godot will build an APK you can download on your device. To do this on the command line, use the following:

adb install dodge.apk

Примітка

Можливо, ваш пристрій повинен перебувати в режимі розробника. Для отримання детальної інформації зверніться до документації пристрою.

If your system supports it, connecting a compatible Android device will cause a One-click Deploy button to appear in Godot's playtest button area:

../../_images/export_android_oneclick.png

Натискання цієї кнопки створює APK і копіює його на ваш пристрій за один крок.

iOS

Примітка

To build your game for iOS, you must have a computer running macOS with Xcode installed.

Before exporting, there are some settings that you must complete for the project to export successfully. First, the App Store Team Id, which you can find by logging in to your Apple developer account and looking in the Membership section.

Ви також повинні надати піктограми та зображення екрану, як показано нижче:

../../_images/export_ios_settings.png

Click Export Project and select a destination folder.

Після того, як ви успішно експортували проєкт, ви знайдете такі папки та файли, які були створені у вибраному вами місці:

../../_images/export_xcode_project_folders.png

You can now open the project in Xcode and build the project for iOS. The Xcode build procedure is beyond the scope of this tutorial. See https://help.apple.com/xcode/mac/current/#/devc8c2a6be1 for more information.

HTML5 (web)

Click Export Project on the HTML5 preset. We don't need to change any of the default settings.

Коли експорт завершиться, у вас з’явиться папка, що містить такі файли:

../../_images/export_web_files.png

Viewing the .html file in your browser lets you play the game. However, you can't open the file directly. Instead, it needs to be served by a web server. If you don't have one set up on your computer, you can search online to find suggestions for your specific OS.

Point your browser at the URL where you've placed the HTML file. You may have to wait a few moments while the game loads before you see the start screen.

../../_images/export_web_example.png

The console window beneath the game tells you if anything goes wrong. You can disable it by disabling Export With Debug in the final file dialog that appears when you export the project.

../../_images/export_web_export_with_debug_disabled.png

Примітка

While WebAssembly is supported in all major browsers, it is still an emerging technology and you may find some things that don't work. Make sure you have updated your browser to the most recent version, and report any bugs you find on the Godot GitHub repository.
