Feature Request: Make areas use camera position instead of link's position

[S41L0R]

Hey!

So I had an idea: In Botw Areas control LODs for some actors, and can trigger events. I imagine that Breath of the Wild must have a pointer somewhere to link's position so that areas can access it. Could you make a togglable option to swap this out with a pointer to the camera position? That way, all LODs would work correctly and a lot of other game features would work as well.

Hi,

I'm not sure I understand what you're trying to say. Are you suggesting to clip link to the camera's coordinate?

[S41L0R]

No, not quite.

I'm sure you're familiar with area actors. But in order to work, they obviously need to have a pointer somewhere in memory to link's position. I'm suggesting you see if you can find that theoretical pointer and point it to the camera's position.

This would work for activating areas, but it wouldn't preserve link's location, which could be a disadvantage when all you want to do is make the camera activate areas.

Not that much, honestly.

they obviously need to have a pointer somewhere in memory to link's position.

There are several places where link's position is stored. I could bruteforce the way through but that would involve too much try and error for me (I saw at least 9 places of link's coordinate, which means write a ton of different injections because instructions are quite likely all different).

If you have a proof of concept I'd gladly look at it. I'd love to invest more time on reverse engineering this game more properly but time is a restriction (as this project, like many others, it's only supported by love lol).

Ok, if I find anything I'll let you know. I might work on a proof-of-concept if I find time.

Cool! as a head start (maybe you already know this but anyway~) at the offset 0x113444F0 in WiiU's memory (that's it, Cemu's base memory + 0x113444F0 if you want to check it out in the actual emulator) seems to be a set of link's coordinate that you can use to teleport him.

Happy to wait for your poc!

How would you recommend editing memory?

[etra0]

I can highly recommend you using Cheat Engine for any kind of memory editing. It's really a powerful tool to write PoC injections and mess with game's memory.

Here's a quick CT that may help you to get started with. You can get CEMU's base address (that will be stored at [base_addr]) and you can offset that pointer like if it were Wii U's memory.

Thanks!
