I've known about this glitch where you can unload one of the flame torches in Mars Lighthouse but never been able to replicate it until today.



Here's how its done; http://www.twitch.tv/tl_plexa/v/28696965

Essentially you get an encounter approximately on the same frame as when the torch gets lit, and then after the encounter the torch is missing. I don't think this is usable anywhere else but I'm posting it here in case somewhere here is interested in why it happens and if there's any potential for further abuse.

I keep going over in my brain how they could have coded this for that to happen, and absolutely nothing makes sense. I'm guessing that the unlit torch and the lit torch are different objects in memory, and that for whatever reason the destroy function is called before the battle function, but the instantiation function is called afterward. That's the part that doesn't make sense. I could understand doing a physics check -> battle -> psynergy, but why isn't it just instantiating the new object as the very next call after destroying the old one lol

As for other places this could be useful... I can't think of any. AFAIK you can't get an encounter and cast psynergy on the same frame, so there's very little way to force this to happen outside of rare cases like this where an object in the environment is acting as a psynergy. If there's any other timed events in the game, you might get a similar result. Maybe you could do something with some of the moai in the rocks?

Two separate objects... No init/de-init going on, I don't think?
020323EC = Lit object.
0203246C = Unlit object.

Basically, the unlit object is in its place, and the lit one is at (0,0), when lit, the unlit one goes to (0,0), and the lit one takes its original place....
That doesn't fully explain why battles can be executed between both, but I haven't looked at that part yet....
(I could probably figure it out quickly if I looked at the code. - Maybe later. - Before looking, I have a hunch that each object has its own code for their thing, so wouldn't be surprised if object order meant something... I'm thinking the first frame all object code is executed.... the unlit one disappears... and then all object code is executed, and the lit one appears?)

Remember kids! Before you go on that interview, remember to wash your hands in teawater! *Coughs on hand* (Excuse me, I just coughed up a little teawater, so they're still clean!) You wouldn't want that hiring manager to be unimpressed.

May the force be with you!
Shoo! Why does it smell in here?
Maybe that's the wrong kind of force. *smirk*

Oh, I think I see what's happening. If you watch the video (start around 2:25), it actually does light the torch during the battle init. The battle init saves the state of the room so that it can return to it after the battle, so it probably saves the position of the "lit" torch before the "unlit" torch, which happens the next frame. It makes sense that an object at 0,0 would have its state saved before another arbitrary point, but my explanation isn't quite convincing in that this process shouldn't be spanning multiple frames.

Fox: @Mario Golf/text editing = Nope... And it may be awhile yet. I think I looked into it before... (at least for GS1)... but usually is the case when I come across a particular problem, that it can delay a solution for an extremely long time.

Fox: I saw we need an event this April Fools/Easter... because two holidays are in one, why would we not want to miss having something special? (Unfortunately, there's no one here to make an event be successful.)

Fox: And since that's the case...  I have thought of another fun experiment idea. - What if we had an auction on who should run this site, and waited for 10 people to bid and also for a bare minimum of 24 hours. Who would bid the highest, and how much would that bid be? - The idea is more for lulz (Maybe for April Fools?), and a theory to get an idea of how much the site might be worth as well.
