[ASM] Town Cleaner code

[Maniac]

 mov r3, #0x6F  #Wilted Red Tulips start at 6E

I'll read the rest later.

Thanks for your advices.

I've fixed the ASM source:

@Thumb mode
add r2,pc,#1           
bx r2
.thumb

ldr r0,Map
ldrh r1,MapOffset

ReviveFlowers:
ldrh r2,[r0,r1]
cmp r2, #0x6D
ble WaterFlowers
cmp r2,#0x89
bge WaterFlowers
sub r2,#0x6E

WaterFlowers:
cmp r2, #0x1B
bge RemoveWeeds
strh r2, [r0,r1]

RemoveWeeds:
mov r1, #0xFF
lsl r1, #8
add r1, #0xF1
cmp r2,#0x1E
ble RemoveRafflesia
cmp r2,#0x25
bge RemoveRafflesia
strh r3, [r0,r1]

RemoveRafflesia:
cmp r2, #0x1B
bne RemoveRafflesia2
strh r3, [r0,r1]

RemoveRafflesia2:
cmp r2, #0x89
bne End
strh r3, [r0,r1]

End:
sub r1,#2
bpl ReviveFlowers

bx lr

.arm
Map:
.long 0x21E6D4C
MapOffset:
.short 0x1FFE

Edit: The AR codes in the first post are fixed (2 lines shorter).

It looks like the code posted was compiled with a different source XD. Not only because of the limitation of
only 1 "ldrh r0-r5, LabelHere" rule in thumb, but no where in the code 0xFFF1, or 0x1FFE is seen. o.o

I've just changed 2-3 things because it doesn't want to compile with this source. But don't worry, the code seems to work, I've tested it myself. :P

It doesn't compile because you have two "ldrh r0-r5, LabelHere" things XD :P

[MisterNobody]

Oh that's it ! Thank you I'm going to fix the source again. xD

I made a remove all weeds, and rafflesia code today (In ASM) ^_^
Look at what I did to get FFF1, maybe you could add that to your new source:

@Branch To Thumb
add r0,pc,#1
bx  r0
.thumb

@Fetch 0xfff1
ldr r0, Map
ldrh r1, MapOffset
lsl r2, r1, #3
add r2, #1

Loop:
ldrh r3,[r0,r1]
cmp r3, #0x1B
beq RemoveWeed
blt NoWeed
cmp r3, #0x1F
blt NoWeed
cmp r3, #0x24
ble RemoveWeed
bgt NoWeed
b NoWeed

RemoveWeed:
strh r2,[r0,r1]

NoWeed:
sub r1, #2
bpl Loop
bx lr

.arm
Map:
.long 0x021E3124
MapOffset:
.short 0x1FFE
