Problems with GHZ3 boss

Hello!


It does a pair of days that I have a problem related to Sonic 1... And it is the following one.


I've tried to extend the length of GHZ3, and have achieved it.


Nevertheless, there is something that doesn't move to the perfection: The boss.


In my disassembly I have put this in Resize_GHZ3boss:



Resize_GHZ3boss:
cmpi.w #$960,($FFFFF700).w


bcc.s loc_6EB0


subq.b #2,($FFFFF742).w


loc_6EB0:


cmpi.w #$3560,($FFFFF700).w


bcs.s locret_6EE8


bsr.w SingleObjLoad


bne.s loc_6ED0


move.b #$3D,0(a1) ; load GHZ boss object


move.w #$3660,8(a1)


move.w #$280,$C(a1)


loc_6ED0:


move.w #$8C,d0


bsr.w PlaySound ; play boss music


move.b #1,($FFFFF7AA).w ; lock screen


addq.b #2,($FFFFF742).w


moveq #$11,d0


bra.w LoadPLC ; load boss patterns



Nevertheless, the boss goes to his original position...


I have tried everything but it has been in vain.


Might anybody to say to me what is what I do bad? Is there anything more that it should do?


Thank you very much in advance.

 

Obj3D contains positions that you need to change yourself, an alternative would be to use relative positioning, then you can add the boss object like an ordinary one in SonED2.

 

What line exactly? I have looked for all sides and I don't see anything...

 

$30(ax) and $38(ax) are what you are looking for. For that boss, 8(ax) is copied to $30(ax) and $C(ax) is copied to $38(ax); (ax) is (a0), (a1), ect.


Edit: I think the labels you are looking for are the following. But there may be others.

Code:

ObjE0_ShipMove

Code:

ObjE0_MakeBall

Code:

ObjE0_ShipStart

 

I've found the above mentioned lines, but: is it to change from 8 to $30 or the other way round?


Sorry for the ignorance, but the fact is that I don't find out very well...

 

No no, dont touch $30 or $38, the boss code already copies the x position to $30 and y position to $38 so edit some values around. For example:

Code:

move.w  #$2960,$30(a0); set the boss to load at position $2960 at x-axis

$2960 is the value you are looking for, change it to the x position needed. Same as y position lines.

 

To the end my problem has been solved. The boss moves perfectly in the position that I was wishing. Thank you!
