Sign Problems

I'm trying to make a sign for save games. So far it somewhat works, but only subtype $0 will show its sprite.


Code:



Obj4F: ; XREF: Obj_Index
moveq #0,d0


move.b $24(a0),d0


move.w Obj4F_Index(pc,d0.w),d1


jmp Obj4F_Index(pc,d1.w)


rts


;===========================================================================


Obj4F_Index: dc.w Obj4F_Main-Obj4F_Index ; Jumped to if #0 is in $24(a0)


dc.w Obj4F_Subtype-Obj4F_Index ; Jumped to if #2 is in $24(a0)


; ===========================================================================


Obj4F_Main:


addq.b #2,$24(a0) ; adds to the routine so this isn't run again


move.w #$4000,2(a0) ; moves #$4000 to the art tile's SST (it's 2 in S1 and S2)


move.l #HUBSignMap,4(a0) ; moves the mappings into the mapping's SST


move.b #4,1(a0) ; use screen coordinates (such as the ones you see in debug mode)


move.b #4,$18(a0) ; set priority (if other objects have a priority of a number less then 4 then the other object will be seen over this one if they interact)


move.w $C(a0),$2C(a0) ; store a copy of the y coordinate ($C(a0) is y coordingate in S1 and S2 and $2C(a0) is scratch ram)


move.w $C(a0),$34(a0) ; store another copy of the y coordinate


move.w 8(a0),$32(a0) ; store a copy of the x coordinate


move.w #$80,$26(a0) ; move #$80 into $26(a0) (to be used later)


move.w #$3E8,$02(a0)


Obj4F_Subtype:


Obj4F_Subtype6:


cmpi.w #$6,$28(a0) ; is object subtype 6?


bne.s Obj4F_End ; If not, branch


move.w #$5,$1A(a1) ; Use frame $5


move.b #$47,$19(a0) ; width of object in pixels


jmp DisplaySprite


rts


Obj4f_Subtype5:


cmpi.w #$5,$28(a0) ; is object subtype 5?


bne.s Obj4F_SubType4 ; If not, branch


move.w #$4,$1A(a1) ; Use frame $4


move.b #$38,$19(a0) ; width of object in pixels


jmp DisplaySprite


Obj4F_SubType4:


cmpi.w #$4,$28(a0) ; is object subtype 4?


bne.s Obj4F_Subtype3 ; If not, branch


move.w #$3,$1A(a1) ; Use frame $3


move.b #$30,$19(a0) ; width of object in pixels


jmp DisplaySprite


Obj4F_Subtype3:


cmpi.w #$3,$28(a0) ; is object subtype 3?


bne.s Obj4F_Subtype2 ; If not, branch


move.w #$2,$1A(a1) ; Use frame $2


move.b #$30,$19(a0) ; width of object in pixels


jmp DisplaySprite


Obj4F_Subtype2:


cmpi.w #$2,$28(a0) ; is object subtype 2?


beq.s Obj4F_Subtype1 ; If not, branch


move.w #$1,$1A(a1) ; Use frame $1


move.b #$30,$19(a0) ; width of object in pixels


jmp DisplaySprite


Obj4F_Subtype1:


move.w #$0,$1A(a1) ; Use frame $0


move.b #$30,$19(a0) ; width of object in pixels


jmp DisplaySprite


Obj4F_End:


rts



Screenshot too.

 

The object subtype is a byte, not a word. So basically instead of this:



cmpi.w #$6,$28(a0) ; is object subtype 6?



You want this:

Code:

		cmpi.b	#$6,$28(a0) ; is object subtype 6?

 

Still doesn't want to work.

 

Never mind us, we put the wrong object ID and fucked up a branch.
