wolf-ecs-system-transform v0.1.0

wolf-ecs-query-inline

A Babel plugin to inline and optimise WolfECS query iteration.

Usage

Install Babel first if you haven't already:

npm i @babel/cli @babel/core -D

Install the plugin:

npm i wolf-ecs-query-inline

Add the plugin to your babel.config.json:

{
  "plugins": [
    "wolf-ecs-query-inline"
  ]
}

More info on Babel config here.

Finally, replace any instances of query.forEach you want to inline with query._forEach. This is to prevent name collisions with other functions such as Array.prototype.forEach.

Caveats

• return is not yet supported.
• The argument passed to _forEach must be a function expression. (function() {} or () => {})
• Arrow functions must have braces.
• _forEach can't be used as a method name elsewhere, otherwise it will also be mistakenly compiled into a query iteration loop.
