    New to Splat?

    If you are new to Splat, it is highly recommended that you try out the tutorial project.

    Create a new Game

    1. Clone or download a zip of the starter project

    2. (skip this step if you are cloning the repo) The zip file should be called Unzip this file and you will be left with a folder named splat-ecs-starter-project.

    3. In your terminal navigate into the splat-ecs-starter-project folder.

    cd /Path/To/splat-ecs-starter-project

    1. Next we will run npm install to install Splat ECS and all of it's modules:

    npm install 5. This will install all of the game and engine dependencies from NPM — it can take a couple of minutes. If you see any warning (denoted by npm WARN) this is okay, this just means that a package Splat-ECS uses is out of date it should not effect your game and newer versions of Splat-ECS Starter Project will take care of this issue. You will know npm install is finished when the terminal returns to your command prompt (you will see your username).

    1. To run a Splat ECS game all you need to do is navigate to the project folder in your terminal and type npm start This will run webpack, which builds your game and also runs eslint which checks your JavaScript code for errors.

    2. You should try running your game to make sure it is working before you continue. When the last line in your terminal reads 'webpack: bundle is now VALID.' this means webpack is done and now you can open a browser and go to localhost:4000.

    The Splat ECS sample game is just white screen with a black-outlined square you can control with WASD, or arrow keys. Test that this is working and note that if the keys are not working you may need to click inside the browser window to give the game your 'focus'.
