I knew the time would come when I ask another question. I have a level script that activates when you do a certain something. Everything works, however one of the two involved person events doesn't show up (removing the flag from it makes it show up permanently, but it is obviously not what I want) with the "showsprite" command. It's weird, because the other one does. Here is a screenshot of the map. Please don't mind the WIP map. Also note that the sprite uses flag 37 (the other one uses 36)

This is just a piece of the map because it is actually 48x40. This portion is in the middle of it.

I made sure no level script interfered with anything, so I hope somebody can help.

Go to header
and the map scripts. Choose there on entering map/not on menu close.
Then make your script, normal with hidesprite, specifically, in your level script you need the flag.
So it should be for the on entering map/not on menu close like this for example.

#dynamic offset

#org @start
checkflag (flag)
hidesprite 0x(NPC number)
setflag (flag number for this script should be added on the NPC I.D)
release
end

then on your level script.
Just add show sprite. For showsprite to happen doesn't need flags to add in NPC by the way.
It will automatically happen if added in script.
Then you're good to go!

Also, wrong section. Should be on script help thread. :(

Hi. Thanks for the help, but unfortunately, the script (neither the type or the script itself) is not the problem. There's something weird going on with the flags, so I don't think the script help thread is suitable for this. I might be wrong, though.
Though I will try to use on entering map as the type and see what happens.
Huh, now that's weird. Swapping the person event numbers makes the first rival not appear and the second one appear. There's something strange going on and I will try to figure out what it is.
Well, I was able to fix the problem. It seems that moving the showsprite command to a location where the camera has scrolled to the scene fixed the problem. Conclusion: showsprite without a clearflag doesn't work if the sprite you're trying to show is way off screen. You learn something new every day.

(also, am I the only member of the PokéCommunity to realise that showsprite and hidesprite automatically do setflag/clearflag, so it's just a waste of space to use them)

You need the Soul Badge (number 6, from Koga in the original game) in order to able to use Surf outside of battle. Currently, it has been only discovered how to prevent the badge check in the Pokémon menu but not on the overworld.

I actually found all of the offsets at one point. It is very simple to do if you know ASM. However, I don't remember where they are.

You need to disable the call to the flagdecrypter that happens whenever you use surf. There are multiple calls to it by bl. It's offset is 0x0806E5C0 (I think this is the flagdecrypter that is used here.). Either way, set a breakpoint on that and then try to surf. Ideally, it should only run when a flag needs to be checked, so it should break only when the surf flag is being checked. From there, you can work backwards using the LR to find the routine which called it. If I remember correctly, this routine will have the flag number loaded into a register, then there is a bl to the decrypter, and then a cmp. The cmp and bl can then be overwritten so that the action which is called when the flag is set is always called, even if it not set.

If you don't know ASM, never a better time to learn. Trust me, it makes hacking a lot more fun and interesting. ASM is the gateway into finally understanding what you are doing when you hack and opens up every single possibility.

It's actually at 0x6E6D0. All flags, with 2 exceptions (those being Pokémon seen and caught flags) are run through this routine when the value is required. IIRC, the flag setter is at 0x6E6A0 and the flag clearer at 0x6E6B8.

I dont know how to ASM and i dont know how to start learning it :/ and i only understand a litle from what u are saying could you explain it in a verry noobish way?

Like:
When you walk,
You put one feet forward
And then the other one
And you repeat that
(The best example i can think of, lol)

The offset I gave was the one called by the checkflag, setflag, and clearflag commands. So, yeah, thanks man for clearing that up.

Your example is the reason I wrote this: http://www.pokemonhackersonline.com/showthread.php?t=14109

Read it and just keep pushing. ASM is the gateway to a new world of hacking that is sooo much better.

Hello~
I'm having a problem with Overworld Editor (Rebirth). I erased frame 0 of the player's sprite and drew this one in place of it (Snivy):

After checking what it looks like in-game, this showed up:

Columns of the sprite are invisible. Does anyone know what the problem is?

Okay, so I have been working on this Firered romhack for a while now and I would like to make a Wintery or frozen themed city. The problem is I suck at tilesets in general. I've seen the 'Frozen' tiles and have tried for a long time trying to import them but just not getting any luck. So basically I would HIGHLY appreciate it if someone could possible convert the tiles into a tileset that is compatible for advance map and send me the download link. Thanks!

So i need to go to a setflag offset (0x806E6A0) in a hex editor and set a breakpoint. What is a breakpoint? 00 or something?

So I am making some e4 rematches in emerald and it seems to be going quite well except for this.

Spoiler:


The problem? It is meant to show Sidney, not Wallace. This also happens to the other e4 members too.
I had to replace a few trainers to fit them (the e4 rematches) in, so that may be causing it somehow?

This is what it should look like.
