Stairs Movement v1.0
FenixFyreX​

Introduction
This script allows movement on a diagonal line to emulate scaling staircases.

Features
- Easily designate a staircase via a region
- Change the speed at which steps are taken to match the pace of moving up/down the staircase
- Alter the y coordinate offset of the character sprite to match the tileset staircase center

Screenshots
Not really applicable as you'd need to see it in action. Just put it in your project, set up a staircase, and try it out.

How to Use
1> Install the script below the default scripts and above Main.
2> Edit the script config to change the staircase region id to your liking.
3> Create a staircase on the map with your tileset.
4> Along the path of the staircase, put that region down.
5> Playtest!
