Godot playground!

A place to play with Godot.

Godot installation

Clone the Godot repository:

mkdir -p ~/workspace && cd ~/workspace
git clone https://github.com/godotengine/godot.git
cd godot
git checkout 3.2.2-stable

Install the Godot dependencies:

sudo apt-get install build-essential scons pkg-config libx11-dev \
    libxcursor-dev libxinerama-dev libgl1-mesa-dev libglu-dev libasound2-dev \
    libpulse-dev libudev-dev libxi-dev libxrandr-dev yasm

Compile Godot:

scons -j8 platform=x11

Testing:

./bin/godot.x11.tools.64

Create a C++ external custom module

Clone this repository:

mkdir -p ~/workspace && cd ~/workspace
git clone https://github.com/osrf/godot_playground.git
cd godot_playground

Compile the custom modules:

cd ~/workspace/godot
scons custom_modules=~/workspace/godot_playground/modules

We're compiling a custom module (summator) as a shared library, that is dynamically loaded when starting our entry point script. The library is located in ~/workspace/godot/bin/libsummator.x11.tools.64.so.

Using the module

We're going to use a script as an entry point:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/workspace/godot/bin ./bin/godot.x11.tools.64 -s ~/workspace/godot_playground/scripts/scene_loader.gd

As expected, we need to use LD_LIBRARY_PATH for being able to find the shared library of our module. The script scene_loader.gd automatically imports our module and uses its functionality.
