Maze Unity

This is a graphical simulation developed in Unity based on the real world experiment from [1] and used from the H-AI_collab_game

This forked from https://github.com/panos-stavrianos/MazeUnity and adjusted accordingly for our purposes.

The environment receives actions (plus other important information) and sends back observations (plus other important information) to H-AI_collab_game.

The above messages are being exchanged via an HTTP server.

H-AI_collab_game and maze_GI_Unity work as HTTP clients.

Edit MazeUnity

  • Download git

    git clone https://github.com/ligerfotis/MazeUnity.git
    
  • Install Unity (Version: 2020.3.13f1)

  • Open with unity

    • If Unity cannot open the project or does not recognize it, create a new project and replace the folders.
  • Remove default scene

  • Drag and drop main scene from Scenes in the Hierarchy

Add Rider in unity (Recommended for editting)

Play

Prerequisites

Play in Unity Editor

Just open the game in Unity and press the play button. See here for connection instructions

Every time a user opens the link to the webgl in the browser the game is being sent to it from a docker.

Start webgl server with docker
  • Build Settings -> web_build -> (switch platform) -> build

  • Choose web_build and name it “webgl”

  • Go to to MazeUnity/web_build

      cd MazeUnity/web_build
    
  • Edit webgl.conf 'server_name' to the name of your server without the ‘http://’ header (default: localhost)

  • Make sure the ports used below are open.

  •   docker build -t <image_name>:<version> . (docker build -t maze-unity:1.0.0 .)
    
  •   docker run -p <host_port>:80 <image_name>:<image_version> (docker run -p 12000:80 maze-unity:1.0.0)
    
  • Open <server_name>:<host_port> (localhost:12000) in a browser.
