Re-Making Teleport code for Acww 1.0

[Demonic722]

Since Dragonboy and Maniac helped me create a coordinates modifier awhile ago, I've decided to remake the teleport code now. I understand what the code does 100%. Special thanks to Dragonboy269 & Maniac for helping with coordinates code, and Drew9561995 for helping me with some dec<->hex converting when I couldn't use the computer XD.

Press L+R+Down to save your position then press L+R+Up to teleport/return to that position.

I know this is a week old but...

Here's some more advice :P

You can store the coordinates in the actual code instead of with free memory. (free memory isn't actually, free, it gets overwritten when you connect to wifi..)
Like...

adr r0, XandYCoords

ldr r1, [r0]
ldr r2, [r0,#4]

str r1, [r0]
str r2, [r0, #4]

....

XandYCoords:
.long 0x00000, 0x00000

[Demonic722]

Whoa XD, I never knew you could do:

XandYCoords:
.long 0x00000, 0x00000

I thought you needed to add #8 to the X-coordinate to get to the y-coordinate.

[dragonboy269]

If you're using THUMB mode, sometimes it's actually better to put addresses that way.
For example, THUMB is picky, and things don't compile the way you want them to sometimes.
Like, trying to load two hwords

ldrh r0, Activator
ldrh r1, Done
@@@@@
Activator:
.ascii "zr"
Done:
.ascii "$$"

that probably won't work, but...

adr r0, Activator_Done
ldrh r1, [r0,#2]
ldrh r0, [r0]
@@@@@
Activator_Done:
.ascii "zr", "$$"

this will work

And now Maniac won't have a reason to bug you about doing what I used to do

ldrh r0, =0x727A
ldrh r1, =0x2424

[Demonic722]

adr r0, Activator_Done
ldrh r1, [r0,#2]
ldrh r0, [r0]
@@@@@
Activator_Done:
.ascii "zr", "$$"

Soo, by adding #2 allows you to use:

.ascii "zr", "$$"

Er in other words, two literals could be defined on one literal rather than doing (two seperate literals):

Activator:
.ascii "zr"
Done:
.ascii "$$"

?

Well, if you have two hwords, the difference between each of them is #2
if you have two bytes, the difference is only #1, and if you have two words, the difference is #4

You can even have the compiler calculate it for you, like....

.long 0x0, Hword2 - Hword1
.long 0x0, Byte2 - Byte1
.long 0x0, Word2 - Word1

Word1:
.long 0x21D88FE
Word2:
.long 0x22AF136
Hword1:
.short 0x14FD
Hword2:
.short 0xFFF1
Byte1:
.byte 0x0
Byte2:
.byte 0x1

Which should compile into

023FF090 012FFF11
E0000000 00000026
00000000 00000002
00000000 00000001
00000000 00000004
021D88FE 022AF136
FFF114FD 00000100
023FF090 E3520003

the first line says "2" the next says "1" and the next says "4" :P

[Demonic722]

I never knew you could do that XD...so this basically tells you the difference between byte sizes..interesting I guess that:

adr r0, XandYCoords
 
ldr r1, [r0]
ldr r2, [r0,#4]
 
str r1, [r0]
str r2, [r0, #4]

Adding #4 makes sense now since the difference between words are #4, but what about this line:

XandYCoords:
.long 0x00000, 0x00000

Why only write .long 0x00000 (with five zeroes) and not 8?

[dragonboy269]

Well, technically it still writes 8, but it won't be using the 8 because ACWW coordinates only use 5 digits, like 0x20FD7
It's just a way of organizing it and showing the expected data length.

[Demonic722]

Okay, I understand. I would ask another question refering to free memory but it's a bit off topic...I'll PM you instead.
