Godot Remote

This is cross platform native module for Godot Engine v3 for control apps and games over WiFi or ADB.

If you are developing on a non-touch device, this module is the best way to quickly test touch input or test mobile sensors data.

Support

Compiling the Module

As a module

configure environment to build editor for your platform (you need to clone 3.2 branch not master)
copy godot_remote folder to the modules/ directory or make symlink
compile engine with instructions from documentation above (e.g. scons p=windows tools=yes -j[place here count of your CPU threads])
run bin/godot[based on config].

If everything compiles successfully, you'll find the new category in project settings Debug/Godot Remote where you can configure server.

As a GDNative library

Configure environment to build editor for your platform
Generate api.json for GDNative api. bin/godot --gdnative-generate-json-api api.json
Copy api.json to the root directory of this repository
Compile godot-cpp (e.g. in godot-cpp directory run scons generate_bindings=true platform=windows target=release bits=64 -j8 ../api.json)
Compile module for your platform (Available platforms: windows, osx, linux, ios, android. Tested platforms: windows, linux, android)
1. For android: Run in root directory [path to your android ndk root dir]/ndk-build NDK_PROJECT_PATH=. APP_BUILD_SCRIPT=Android.mk APP_PLATFORM=android-21
2. For all other platforms: scons platform=windows target=release -j8
Use produced library in bin/

GDNative has limitations so here GodotRemote is not a singleton and you need to create autoload scene with attached NativeScript for GodotRemote class. Also there is no any settings in Debug/Godot Remote.

Enum constants in this version changed too (see [API Reference] )

Currently, the GDNative version does not support the assignment of sensor data, so the editor will not support accelerometer, gyroscope, etc. Also, this version may crash at a random moment.

If GDNative becomes more stable, I will add the necessary code to easily integrate this module into any project, but now it just works.. sometimes.

Additional parameters

Also module has additional compilation parameters for scons script

godot_remote_no_default_resources (yes/no) default no - compile with or without default resources
godot_remote_disable_server (yes/no) default no - do not include server code
godot_remote_disable_client (yes/no) default no - do not include client code

Download

Precompiled binaries can be found on GitHub Releases page

Mobile app

On releases page you can found precompiled mobile app but also it can be downloaded from Google Play

Configure Mobile App

To open settings menu you need to touch the screen with 5 fingers at once.

Then you'll see this settings menu:

Important: after entering server address you should apply it by pressing Set Type and Address or Set Type and Port

Custom client

If need to support other platforms or you need a specific version of module integrated to the client app, you can build client from source code placed here.

If you don't want to use my client app you can check the example client project and build your own client.

Or you can donate me some money with request to buy iPhone and adapt a client for it 🙂

API Reference

Methods will be declared follows this template:

return_type function_name([arg_name1 : type [= defalut value]][, arg_name2 : type [= defalut value]])

Important: All enums in GDNative version is exposed in GodotRemote class because of limitations. For example, if you want to use StreamState.STREAM_ACTIVE from GRClient you need to get property GRClient_STREAM_ACTIVE of GodotRemote object

# Godot module:
GRClient.STREAM_ACTIVE:

# GDNative
# *GodotRemote is autoload scene with attached NativeScript
GodotRemote.GRClient_STREAM_ACTIVE

Custom Input Scenes

In custom input scenes you can use everything you want but to send InputEvent's from client to server you must emulate input. Or use the send_user_data() method and user_data_received signal for send and receive custom packets. Example:

# -- With InputEvent's

func _on_pressed():
    # Create event for pressed state
    var iea_p = InputEventAction.new()
    iea_p.pressed = true
    iea_p.action = "jump"
    # Create event for released state
    var iea_r = InputEventAction.new()
    iea_r.pressed = false
    iea_p.action = "jump"
    # Parse event to send it to the server
    Input.parse_input_event(iea_p)
    Input.parse_input_event(iea_r)

# -- With custom packets

# on first device
func _ready():
    GodotRemote.get_device().connect("user_data_received", self, "_on_user_data_received")

func _on_user_data_received(id, data):
    print("Received packet: %s, data: %s" % [id, data])

# on second device
func _on_button_pressed():
    GodotRemote.get_device().send_user_data("bg_color", color, false)
