This is a GB Studio (v2.0) engine mod that allows for diagonal movement within top-down mode.

Features:

The player will not stop moving when walking diagonally into a collision but will strafe in the next unblocked direction. For example, if the player holds up and right, this will happen when hitting an obstacle:

Player walks up/right diagonally, hits obstacle and strafes right

Extra feature unrelated to diagonal movement: when players walk up or down (straddling) into a left/right collision, it will be treated as a collision. Currently the player will walk through into the collision which is probably not what you want.

Player walks down into a vertical half-tile (single direction collision) and it will be treated as collision

Installation

To use this mod, eject engine, copy TopDown.c into the location below and replace the existing file:
\assets\engine\src\states\TopDown.c

I have tested it and it seems to work fine but use at your own risk and read up on engine eject first. I take no responsibility if it eats your game.

Why this is needed

As of now, GB Studio 2.0's top-down mode does not have 8 direction (diagonal) movement, it only has 4 directions (up, down, left, right).

Adventure mode has 8-direction movement but there are bugs when walking into one-directional (top/bottom/left/right) collisions. If you do not need to use one-directional collisions, Adventure mode may already suit your needs.
