node-canvas-webgl example

screenshot.js

Generates Screenshots of the bot world

Starting

Linux:

xvfb-run -s "-ac -screen 0 1280x1024x24" node <your script> [...args]

Mac High Sierra:

node <your script> [...args]

Installation:

Installation on a none unix based systems is none trivial. I suggest you install it on something like Ubuntu. Or a Virtual Machine running Ubuntu. Mac OS X may work too, but I have only tested it on 10.13 High Sierra.

Do npm install to install all required node packages.

Troubleshooting (Linux):

If npm fails while installing try installing the following and try again:

sudo apt-get update -y
sudo apt-get install -y xserver-xorg-dev libxi-dev xserver-xorg-dev libxext-dev xvfb

Docker

If you want to run the screenshot example on windows without a vm you can install it in a Docker Container.

Building the Docker image:

cd screenshot-with-node-canvas
docker build . -t screenshot-bot

Running the image and saving the screenshot to the current directory:

docker run -v $(pwd):/usr/src/app/screenshots -e HOST='<server ip address>' -e PORT=<port> screenshot-bot

-e USERNAME=User1 and -e PASSWORD=<Your password> can be added if the server is not running in offline mode.
