Search and teleport (theory)

Well, I've been messing with coordinates and stuff, and I'm thinking of making a code that searches for an item, then when it finds it, it teleports to the first occurrence of that item (and after I get that to work, I'll make it check if you're already at the first item, and if so it'll teleport you to the next)

Since I can view addresses/values etc in game with a code, I found this

Code:

---

00020FD7 = very top left corner
22FD7 = for each full space you move right (or down) this increases by 2
24FD7
26FD7
28FD7
2AFD7
2CFD7
2EFD7
30FD7
etc

---

However, I'm not quite sure how to get them to match how the game handles item slots (like, instead of going left to right all the way, it goes in 16/16 grids)

Any help?

....remind me to work on this when you see me on msn.

For those who are interested, so far I have this...

Code:

---

This was done in like... 3 min >_> Sooooo it may be sloppy. unno.

By the way thanks a lot for helping me with this
I try looking at RTWE's "formulation" and I have no idea what he's saying... XD

Still trying to decide how I want to do this.. lol where is toe when you need him...

Oh and I figured out why the top right corner is weird XD
The very top left is 00020FD7, and the very left of the top right spot is 0009EFD7
so the middle would be just a bit over

It goes left to right and increases by 0x2000

Would it be possible to teleport by clicking on a part of the map?

Probably


But anyway, here's what I found for each item slot

Code:

---

extreme left (or  top) of item slot

20FD7

extreme right (or bottom) of item slot

21029

difference:

#0x52

Considering that hes been invisible half the time I doubt you actually know how much he is actually on..

Well he changed his contact info and added different interests XD

Oh and, I might be able to do this by myself, I've just never really spent any time on it XD
It's actually quite simple, kinda

Divide by 16, for each time it has 16, add 2000 to the y coordinate, then add remainder multiplied by 0x2000 to the x coordinate

Then, also, since there 4 of these "blocks" on each row, do another check to divide by those blocks, etc

Okay Here's what I found

Code:

---

Set a register for your x and y coordinates (make it start off as 20FD7 for each of them)
When you do a search for the item, set a register to #0, then each time the search loops, you add 1 to the value in that register

when it detects the item...

first

divide by 1024? (total item slots for the first row of acres)

multiply the answer by #0x2000 then by #16 and add that to the y coordinates

then divide by 256, number of "blocks"
multiply that by #0x2000 and add that to the x coordinates


then with the remainder, divide that by #16, multiply the answer by #0x2000 and add that to the y coordinates

and with the remainder of that, multiply by #0x2000 and add that to the x coordinates

---

That should work, although there might be an easier way
But that would work for sure.

Tell me if you see anything wrong with this source. I haven't tested it yet but it should work

Code:

---

FAIL source XD

---

Edit: When I try that code, it works the opposite of how I want it XD well, not exactly opposite

If the item is to the right on the left side of an acre, it teleports me instead to the right on the left side of the acre (like, the opposite side of town)

By the way it works in a few places, like it takes me directly on top of the item

But for others, it puts me on the exact opposite side of town, like
I type in the hex for a Museum, and it acts like a mirror, it puts me in the exact opposite side of town as my Museum

Got it working :)

Just want everyone to know, I used parts of Toenailed's RTWE in this.



I'm thinking of making a new "Search/teleport" code except for 2 differences

one, I use all my own coding, and two, it doesn't teleport you to the item, it slowly drags your character toward the item (I dunno I just think that's fun XD)

First it'll search, store the item's coordinates in free memory, set a byte to a 1,
then the code will load your coordinates, check what they are in relation to the items coordinates, then start "correcting" them slowly (like, adding #0x20 to the x coordinates until they're equal to the item's and setting the byte to 2, then adding #0x20 to the y coordinates until they're equal to the item's and resetting the byte to 0)
I can also make it so you can activate it with one button press (not having to hold) and then deactivate it if you want at any time with a different button combo


Once I get that working, I'll make it change the direction your player is facing to the direction he/she is sliding

Code:

---

Address at pointer minus #0x516 is direction player is facing

0000 is down
4000 is right
8000 is up
C000 is left

(I found that myself)

and north west say?

In between those

.... I can guess what number it is..but anywho. Make sure if you slowly change it that you do greater then or equal to.. Not just equal to ;)
