Making knuckles break walls S2

Im using the leftover S1 breakable wall object in S2 (xenowhirl), and have knuckles as a character, so naturally, I want him to punch through walls. I can't get it to work right though. CLownacy suggestted the below code:

loc_15DAE:
    lea    (MainCharacter).w,a1 ; a1=character
    cmpi.b    #$D1,(a1)    ; is player Knuckles?
    beq.s    .knux        ; if so, he doesn't need to be checked for rolling
    cmpi.b    #2,anim(a1)
    bne.s    return_15DAC
.knux:
    move.w    objoff_30(a0),d0
    bpl.s    loc_15DC2
    neg.w    d0

But it doesn't work right, only sometimes.

 

Here's the fix. Under loc_15DC2, change the first two lines to this:

Code:

	cmpi.b	#$D1,(a1)	; is player Knuckles?
	beq.s	.knux		; if so, he doesn't need to be checked for speed, either
	cmpi.w	#$480,d0	; is player's speed $480 or higher?
	blo.s	return_15DAC	; if not, branch

 

Um, now the game freezes when knuckles touches a wall...

It only freezes when playing as knuckles, but still, gamebreaking...

Edit: I managed to fix it, you had a logic error which caused a loop, the beq.s should not point to .knux

Edit2: How rude of me! It works! Thank you so much :3

 

Oops. Yeah, like before, that code snippet is supposed to end with a .knux label. Weird that you got it to build. I've had loc_ labels invalidate the closest of .labels by being between the label and the branch.
