Teleporting code

[toonlink444]

Back on the scene for a while so for my next code I was thinking of a teleporting code. I figure you have to find the x y and z values then record them so you go back there. My question is how would you record a value as in save it. And I'm guessing to find the x y and z values you just move around.

Load them into gecko registers or use asm

How would I load into to a gecko register?

How would I load into to a gecko register?

I think that my codes are good for learning purpoises. ;D
Actually, I made all kinds of teleporters for many different games. 8)

Importance order of these examples:
1.) ASM (always possible, can be un-reasonable/un-convenient since it may affect other players aswell)
2.) Pointer (mostly possible)
3.) Base Address (seldomly possible)

NOTE: These are examples on how to do it.

Understood? ;D

I figured it out last night and it worked pretty well, but the Y axis was saved wrong and put me high in the air. Plus the gravity stopped working.

The code now only works if you don't travel that far from the saved coordinates is there a way to extend it.

This is just a guess, but most games store "current" XYZ coords and "previous frame" XYZ coords... I wouldn't be surprised if some games don't like it when the current coords are suddenly way different from the previous coords.

But, I may be wrong.

[toonlink444]

Hmmmm :confused: so what would a good way to find a previous frame coords

[biolizard89]

They tend to be very close to current coords in memory.  In fact, they may be exactly next to them.  Open memory viewer with the game paused, and go frame-by-frame; note the current X coord while moving, go forward one frame, and look for that value to appear.  Alternatively, breakpoints might be able to find them.

Again, I'm not certain that this is the issue you're having, but I've definitely seen games that misbehave if you poke the current coords to something very far from the previous coords.  (In particular, Super Smash Bros Melee doesn't like it at all.)  I think this is because the previous coords are used to calculate collision detection, but don't quote me on that.

Found the issue the screen moves when you move so I need to find the value of where the screen is to make the screen move to the place the coords were.
Any ideas on how to do this?

this is common with almost all teleport codes i've used. and what biolizard89 mentioned may be the reason why the teleporting code won't work when the game has loaded a new area. from what i've observed when making teleport codes, there are 3 addresses you can poke and see a change in character position, and there are another 3 that also show the character coordinates but when poked won't cause a change. those addresses aren't far from the actual coordinate addresses. they are usually above them. simply try to save the current coordinates of the latter addresses i mentioned, along with the character coordinates you already found and use in your teleporting code, to see if it solves the problem.

[toonlink444]

I've seen them I'll give it a shot.

Yep, that's what I've seen as well.  If you're not moving, the previous and current XYZ coords will be the same, so they'll show up on a search.

Hmm I made a teleport code for new super mario bros wii and it worked but for super mario galaxy I found the xyz corrds but when I poked them nothing changed.

[dcx2]

It depends on "when" you poke them.

The game runs in frames.  At some point in the frame, the code handler runs.  (this is not always technically true, but it's close enough to true for this discussion)

At some point in time, the game writes Mario's coordinates to memory.  Some time later, it reads them back and does stuff with them.  If the selected hook causes the code handler to run after the coordinates are written, and before they are read, then everything will work.

However, if the selected hook causes the code handler to run after the coordinates are *read* and before they are *written*, then whatever the code handler writes will be over-written by the game.

I ran into this with my Televitation code.  I had to write a C2 code that hooked the game just after the coordinates were written to memory, so that my C2 could over-write those coordinates when I used the activator.

EDIT:

It's also possible you found the "last frame coordinates", so that when you poked them, you didn't actually change your coordinates.
