Simple Diagonal Movement

Simple Diagonal Movement 1.0
Shaz

Introduction
This scriplet, requested by Despain, allows you to use terrain tags or regions to identify tiles where the player should automatically move diagonally when pressing the left and right arrow keys (stairs, slopes, etc). It avoids the player having to use the up/down keys, and removes the need for events to force diagonal movement.

Features
- Use terrain tags or map regions.
- Affects player, followers and events.

Screenshots

How to Use
Paste the script below others in the Materials section.

Note - for demonstration purposes, I made all of these tiles passable in the editor. Normally you wouldn't be able to walk on them at all, and this script would not change that.

To use with Terrain Tags:

Spoiler

Set terrain tags on tiles to indicate where the player will move diagonally up or diagonally down when going from left to right:

Change the script to use terrain tags:

Code:

TERRAIN_LOOKUP = true UPLR = 1DOWNLR = 2

To use with Region IDs:

Spoiler

Paint tiles in the Region layer to indicate where the player will move diagonally up or diagonally down when going from left to right:

Change the script to use regions:

Code:

TERRAIN_LOOKUP = falseUPLR = 62DOWNLR = 63
