Text activator (ASM)

I'm having trouble making a text activator. I figured I'd start out simple, so here's what I have:

Code:

---

ldr r0, =0x021D88FE       
ldr r5, =0x022AF136

@check if code should run
checkF:
ldrb r6, [r5]
add r5,#1
cmp r6,#0x06
beq checkL
b exit

checkL:
ldrb r6, [r5]
add r5,#1
cmp r6,#0x0C
beq checkA
b exit

checkA:
ldrb r6, [r5]
add r5,#2
cmp r6,#0x01
beq run
b exit

run:
mov r8, #0x0019
strh r8, [r0]
b exit

exit:
bx lr

---

I want it so when you say "FLA" it'll put a blue rose in slot one of your pockets, but when I did the code without "b exit" after the run section, it just froze, and when I added "b exit" nothing happened

There's no conditional for when you compare and it's not equal.

After Check F, get rid of b exit and add bne checkF. Also, after Check L, get rid of b exit and add bne checkF

wouldn't bne checkF make it start over from the most recent character?

I want it to check if you typed FLA (only as first 3 characters) and if you did it makes your first inventory slot a blue rose, if not it doesn't do anything

... A snippet from one of my codes...

Code:

---

ldrh r1, Activator
ldr r0, Text
ldrh r2,[r0]
cmp r2, r1
bxne lr

---

Code:

---

Text:
.long 0x22AF136
Activator:
.ascii "zr"

---

>___> it works btw ;) though thats obviously not the full code.

Well yes, but when it compares and it's not equal you want the entire check to start over. If it confirms F then not L and you make it keep checking L instead of going back to F you could get something like this:

Character says: Fart!
Check reads F and moves on to second check for L
Character then says: SLOW connection.
Check reads L in second message and moves on to A check.
Character finally says: SCAMMER!
Check reads A in the third message and you get the final code effect.

I know it's highly unlikely, but each time you encounter a Not Equal in your compare you want to completely restart the check. It's really up to you, though. You at least need to add something for NE. Even if it is restarting the current check instead of all the checks.

I hope this wasn't too confusing...

Code:

---

ldr r0, =0x021D88FE       
ldr r5, =0x022AF136

@check if code should run
checkF:
ldrb r6, [r5]
add r5,#1
cmp r6,#0x06
beq checkL
bne checkF

checkL:
ldrb r6, [r5]
add r5,#1
cmp r6,#0x0C
beq checkA
bne checkF

checkA:
ldrb r6, [r5]
add r5,#2
cmp r6,#0x01
beq run
bne checkF

run:
mov r8, #0x0019
strh r8, [r0]
b exit

exit:
bx lr

I get it now, but I think I'll just go with Maniac's way ;)

Yeah, I never thought to use that as a latch. Muchhhh simpler.

Edit: Make sure that after you use the text values, change the ZR part at the end of your main code to something else so it doesn't create an infinite loop.

yeah, he told me that on MSN

Dang straight >__> lol Good luck btw :)
