How to use the Arcade Slopes plugin

I have been searching for a while, trying to figure out how to be able to use this plugin. It looks like there a some instructions on how to install and use it but I think what I am getting confused with is where to use “game.plugins.add(Phaser.Plugin.ArcadeSlopes)”. I have my game separated into multiple files, one for the config and game, one for my main scene, and then separate files for the player, map, objects, etc… For this specific plugin, where do I need to add it to be able to use it? I’m am very new to phaser and I haven’t been able to find much online about plugins.

phaser-arcade-slopes is for Phaser 2 only. :frowning:
