Simple example using C

This is a small example using C to create a GDNative script that just showcases some very simple bare bones calls.

Language: GDNative C

Renderer: GLES 2

Dependencies:

You need Godot headers, this is now a Git submodule of this repo.
clang, gcc, or any decent C compiler that's C11 compatible.

Compile with SCons (cross platform)

You can use SCons to compile the library if you have it installed:

scons platform=PLATFORM

Where PLATFORM is: windows, linuxbsd, or macos.

Manually compiling

Linux

To compile the library on Linux, do

cd src
clang -std=c11 -fPIC -c -I../godot-headers simple.c -o simple.os
clang -shared simple.os -o ../project/gdnative/linuxbsd/libsimple.so

This creates the file libsimple.so in the project/gdnative/linuxbsd directory.

macOS

On macOS:

cd src
clang -std=c11 -fPIC -c -I../godot-headers simple.c -o simple.os -arch x86_64
clang -dynamiclib simple.os -o ../project/gdnative/macos/libsimple.dylib -arch x86_64

This creates the file libsimple.dylib in the project/gdnative/macos directory.

Windows

On Windows:

cd src
cl /Fosimple.obj /c simple.c /nologo -EHsc -DNDEBUG /MD /I. /I../godot-headers
link /nologo /dll /out:..\project\gdnative\windows\libsimple.dll /implib:..\project\gdnative\windows\libsimple.lib simple.obj

This creates the file libsimple.dll in the project/gdnative/windows directory.

Usage

Create a new object using load("res://simple.gdns").new()

This object has following methods you can use:

get_data()
