This project is used to compile a GDExtension (godot engine cpp extension), and try to use xmake to manage the project.

Forked from [Github](https://github.com/chaosddp/gdextension-cpp-xmake-template)

## Install xmake

Install xmake from [here](https://xmake.io/#/guide/installation).

## How to use

You must have godot in your path

First modify the *xmake.lua* to change the project name, and other configurations as needed.

```lua

-- project name, this will be the output shared library name
PROJECT_NAME = "gdexample"

-- project version
VERSION = "0.0.1"

-- where is the godot project saved, default is "demo"
GODOT_PROJECT_FOLDER = "demo"

-- where to save the export project, default is "publish"
PUBLISH_FOLDER = "publish"

```

After change the configurations, you can run the following commands to build, run and export.

```sh

# 1. gen gdextension file (only once)
xmake gengdextension

# 2. build the project
xmake

# 3. open the editor at least once (works only in debug mode)
xmake run Editor

# 4. run the demo (works only in debug mode)
xmake run

# 5. export the project, the executable will be under "publish" folder by default
xmake p

# 6. clean the build and publish
xmake clean

# 7. generate a class that inherits from godot class, like Sprite2D
# by default the generated files will save under "src" folder, you can change it by -d folder/under/src
xmake ext-class -n MySprite2D -b Sprite2D -s myexample1 -d sample

```

For better support in vscode, you can use command "Xmake: UpdateIntellisense" to generate *compile_commands.json*, then update "compileCommands" field in *c_cpp_properties.json* to point to the file.

NOTE: not tested on other platforms except windows and linux.
