Completed Reduced Knockback and No Invincibility While Grabbing Ledge

[Zadamanim]

I need a code that removes ledge invincibility altogether. In a world with no ledge invincibility, it becomes extremely easy to edgeguard, though. So to compensate, grabbing the ledge should function similarly to a crouch cancel, you get massively reduced knockback, allowing you to double jump back onto the ledge immediately. If anyone has any tips on how to create this kind of function in the game, or wants to try making it themselves, let me know!

Finally got around to working on this and I thought I was onto something when I found this in Crazy Hand. Unfortunately, both changing the Body State to Normal and changing it to a null self-damage event did nothing to actually remove invincibility. Guess I'll finally have to learn how to use debug dolphin lol.

Well, I think you were on the right track, because those body states appear to originate from subaction event data.

Somewhere in the cliffcatch wait animation interrupt function, there seems to be a hardcoded toggling of the body state that’s used to count down the intangibility timer. It simply toggles the state, meaning that if you remove the subaction event trigger, then it will toggle intangibility ON after the timer is up; rather than off.

---

Here are a pair of overwrites that disables the reading of subaction events for the cliffcatch state transition, and disables the hardcoded toggle. It effectively eliminates the intangibility caused by catching a ledge:

-==-

Vulnerable Ledge Grab
Removes intangibility caused by catching a ledge

1.02 --- 800813e0 ----- 38a00000 -> 38A04000
# disable subaction event reading on action state change for cliffcatch

1.02 --- 8009a8b0 ----- 4bfe0eb1 -> 60000000
# stop toggling of body state on cliff wait

---

To handle the knockback scaling, I’ve created the Defensive Knockback Modifiers code.

The following code includes the above overwrites, the Defensive Knockback Modifiers code, and some default modifiers that scale the knockback of cliffcatch and cliffwait states to 50% applied force:

-==-

Scalable Ledge Vulnerability
Removes intangibility caused by catching a ledge, and scales the knockback applied while being struck from a ledge

# place an arbitrary number of character:action state IDs below these comments:
# FF------ = Internal Character ID
# --FFF--- = Action State ID
# -----FFF = fixed point: 0xF.FF

FF0FC080
FF0FD080
# <- place new modifiers here

# terminator:

1.02 --- 8009a8b0 ----- 4bfe0eb1 -> 60000000

The above code uses 2 knockback modifiers that can be edited to change the scaled knockback:

FF0FC080
FF0FD080

In each of these, the trailing 0x080 represents the decimal number 128/256 -- or 50%

By changing this number, you can change the applied knockback scale.

See here for more details, and let me know if you have any questions.

Thanks so much! I'll be implementing this into MM today!
Edit: I just noticed the Internal Character ID in your example is set to FF, does that mean it effects all characters? Or is that just a placeholder and must be replaced with every character's ID to affect the whole cast?

 

[Zadamanim]

Putting both of those codes in MCM v4.0 gave me this error, should be easy enough to fix though.


A conflict (writing overlap) was detected between these two changes:

"Scalable Ledge Vulnerability"
Offset: 0x7dfc0, Code End: 0x7dfc4

"Vulnerable Ledge Grab"
Offset: 0x7dfc0, Code End: 0x7dfc4

These should not both be enabled. "Vulnerable Ledge Grab" will not be enabled. "Scalable Ledge Vulnerability" may need to be reinstalled.

Edit: Oh I'm just being dumb. If I would have read the description, the Scalable Ledge Vulnerability already includes the vulnerable ledge grab change, lol.

I just noticed the Internal Character ID in your example is set to FF, does that mean it effects all characters?

That's correct. I made a small note about it in the code description:

The character ID may be specified as “FF” to have a modifier apply to all characters.

This should make it easier to apply modifiers to common action states like cliffcatch.
