Completed Expand Melee's Hitbox System to Support up to 8 Active Hitboxes

Introduction

As you may or may not know, Melee's engine only supports up to 4 active hitboxes at a given time. Those who are familiar with editing character move-sets may have noticed that when creating a new hitbox through the Create Hitbox command/subaction event, you could actually enter up to 7 for the hitbox ID but only hitboxes with the IDs 0 to 3 will show up. Taking advantage of this, I aim to patch up Melee's hitbox system to enable the use of hitbox IDs 4, 5, 6 and 7, essentially allowing you to use up to 8 hitboxes in Melee! This will be especially useful for custom characters.

Task List
  1. Fighter Hitboxes (~100% of core patches done)
    • Grab logic ✓
    • Clank/Rebound on players & items ✓
    • Hit logic on players & items ✓
    • Collision bubble drawing ✓
    • Shield logic ✓
    • Hitbox-related subaction event parsing ✓
  2. Item Hitboxes (~100% of core patches done)

HSDraw Usage

In the Create Hitbox event commands, you can now just set the hitboxes to use ids 4, 5, 6 & 7.

Gecko Code

Works with m-ex and vanilla Melee. If using m-ex, add this code in codes.gct. Also works with MCM for vMelee.

Note that you MUST install/update or enable some codes from the Shared Modules thread first if you do not have it before using the code below.

Code: 
$Enable 8 Hitbox Support v1.0.0 [sushie]
*Expands Melee's current hitbox system to support up to 8 hitboxes

Update for 2022-01-29

  • Finished 100% of the core patches required for fighter hitboxes
    • character-specific specials that manually modify hitboxes are not patched (e.g. dk's down-b hitboxes) due to it being low-priority
  • Item collision against fighters & other items are now working properly with correct rehit

Here's a quick video with pk fire having 8 hitboxes:

Update for 2022-02-01
  • All required patches have been completed for item hitboxes. This mod is now ready for release!
  • Last thing before releasing is that I'm currently ensuring full compatibility with my Hitbox Extension mod. You will be able to use hitlag multipliers, hitstun modifiers, etc with all 8 hitboxes
    • So far, both mods work nicely together
    • Still need to update the hitbox extension to support up to 8 hitboxes instead of 4
This is the last update post before I release this mod.

v1.0.0 has now been released! I have also included a custom version of HSDraw that supports up to 8 hitboxes.

This mod is compatible with m-ex and vMelee.
