limboai/gdextension/setup_gdextension.sh

#!/bin/bash

## This script creates project structure needed for LimboAI development using GDExtension.
## Works only on Unix-likes. You can still use the directory layout below, if you are on Windows.
##
## Instructions:
## 1) Create the project root directory, name doesn't matter.
## 2) Inside the project root directory, clone the limboai repository:
##    git clone https://github.com/limbonaut/limboai
## 3) From the project root directory, run:
##    bash ./limboai/gdextension/setup_gdextension.sh
##
## Directory layout:
##   project/ -- call this script from here, directory name doesn't matter.
##   project/limboai/ -- LimboAI repository should be here after you clone it.
##   project/godot-cpp/ -- will be created by this script, unless cloned manually.
##   project/demo/ -- symbolic link (leads to limboai/demo).
##   project/demo/addons/limboai/limboai.gdextension -- symbolid link (leads to limboai/gdextension/limboai.gdextension).
##   project/demo/addons/limboai/icons/ -- symbolic link (leads to icons/).
##   project/SConstruct -- symbolic link (leads to limboai/gdextension/SContruct).
##
##   Note: Symbolic links will be created by this script.
##
## Dependencies: bash, git, python3.
