I actually have no idea how sheath's attack works

[TiKi]

I think this works...!
Do you have any idea about width?

[Kil]

change the numbers afterwards in the same pattern as the first 5 i gave and maybe it's there somewhere, in the next 50 or 60 values

[Willhart]

Actually it looks like you can use lunadll

Use MemAssign w on 0x00B2C6FC to set small demo's height. The next 4 addresses (B2C6FE, B2C700, B2C702, B2C704) are the other characters small height. Then comes the mushroom/tall heights for all 5 characters. After that is maybe the height for other powerups, and beyond that who knows.

Can you give an example of how to increase the small and normal height of demo by one block?

[TiKi]

MemAssign,(address),(height + 32),0,0,w
Would 06 + 10 be 16 or A6?

[Kil]

yes, and small demo should be 0x00B2C6FC and normal should be 0x00B2C706

[TiKi]

Idk what B2C706 + 10 would be pls help

[Willhart]

Thanks. I got it working with this.
#-1
MemAssign,0x00B2C6FC,64,0,0,w
MemAssign,0x00B2C706,96,0,0,w

The graphics should be easy to replace by extending sprites downward. The hitbox for large demo when ducking is still just one block, so I have to be careful with that.

[TiKi]

Yes Link seems to keep his default hitbox when ducking too.
Yes! I finally got SMW Mario's vertical hitboxes to be correct! Thanks a lot Kil! Here's the addresses for Mario BTW, someone should keep these somewhere
MemAssign,0x00B2C6FC,42,0,0,0,w -small
MemAssign,0x00B2C706,58,0,0,0,w - big
MemAssign,0x00B2C710,58,0,0,0,w - fire
MemAssign,0x00B2C71A,58,0,0,0,w - raccoon
MemAssign,0x00B2C724,55,0,0,0,w - tanuki
MemAssign,0x00B2C72E,56,0,0,0,w - hammer
MemAssign,0x00B2C738,58,0,0,0,w - ice

[Kil]

The ducking heights are there somewhere too though. I have this written down



They're probably correct or I wouldn't've written them down

I just noticed that too. It is correct. Now we can have levels where Demo has a large tophat or something.

Edit: that max jump table is silly. It helps for space levels and can prevent player from jumping. Can you share anything else?

Hey where did you get that list?

[Kil]

Maybe some of these will do something

kinda off topic, but do you guys have a list of the names of your a2xt enemies? or do they even have names haha

[raocow]

There is goopa and furbas, and bananasnakes...

[Axon]

thank you guys :D

Could someone please tell me how to resize the fairy/angel?

[re: changing characters' hitboxes]

Yes! I finally got SMW Mario's vertical hitboxes to be correct! Thanks a lot Kil! Here's the addresses for Mario BTW, someone should keep these somewhere
MemAssign,0x00B2C6FC,42,0,0,0,w -small
MemAssign,0x00B2C706,58,0,0,0,w - big
MemAssign,0x00B2C710,58,0,0,0,w - fire
MemAssign,0x00B2C71A,58,0,0,0,w - raccoon
MemAssign,0x00B2C724,55,0,0,0,w - tanuki
MemAssign,0x00B2C72E,56,0,0,0,w - hammer
MemAssign,0x00B2C738,58,0,0,0,w - ice

Okay, so for someone who has no experience with this sort of thing...
0x00B2[...] is the 'address' for "Mario's small hitbox/big hitbox/etc", and the number after it is the height in pixels of said hitbox... and then does 0,0,0,w refer to anything? I assume this sort of thing be done on, say, a game-wide basis like the "no spinjumping/picking up things" in SDS, as well as on a per-level basis too? Pretty sure that's exactly what LunaDLL can do.

Hopefully the addresses for the other characters will be found, too!


By the way, is someone keeping an easily-accessed list of 'what does what' with LunaDLL or anything?

[Kil]

From http://www.gamearchaeology.com/lunaref.txt

Code: Select all

MEM ASSIGN

MemAssign,ADDRESS,VALUE,OPERATION,-,Active time,DATA SIZE

Description -
Sets the internal memory of SMBX.
ADDRESS is the memory address of the thing you want to change. Only a few addresses are known right now.
OPERATION is the way you want to manipulate the memory (adding to it, multiplying from it, subtracting from it...)
VALUE is what value the OPERATION will perform on the ADDRESS. So if you wanted to add 2 to some memory, the value would be 2 and the operation would be addition.
DATA SIZE is the type of data in the memory location. Check the reference at the bottom of the document to find the data size. There's no way to actually know the memory size unless you check RAM or a reference someone has already figured out.

Notes -

Known addresses:
0x00B2C8B4 - w = P switch freeze effect on or off
0x00B2C5A8 - w = Current coin count
0x00B2C5AC - f = Player lives
0x00B2C8C4 - w = "You have cheated" variable. 0xFFFF = you've cheated, 0x0 = you haven't cheated

There are 6 types of OPERATION to be performed on VALUE:
OPERATION = 0 = Assign. VALUE will be set.
OPERATION = 1 = Add. VALUE will be added to the current value.
OPERATION = 2 = Subtract. VALUE will be subtracted from the current value.
OPERATION = 3 = Multiply. The current value will be multiplied by VALUE.
OPERATION = 4 = Divide. The current value will be divided by VALUE.
OPERATION = 5 = XOR. The current value will have a bitwise exclusive-or operation performed on it against VALUE.

There are 5 types of DATA SIZE that can be set
b = byte (1 byte of memory)
w = word (2 bytes of memory)
dw = double word (4 bytes of memory)
f = float / decimal (4 bytes of memory)
df = double float / double precision decimal (8 bytes of memory)

Example -

// Add 50 lives to the player life count
MemAssign,0x00B2C5AC,50,1,0,1,f

So MemAssign,0x00B2C6FC,42,0,0,0,w is doing an "Assign" operation on that hitbox memory and setting it to 42. The 5th 0 means active time = infinite, which is unnecessary. That should be a 1 because the game never goes back and resets the hitbox.

[TiKi]

Can SMBX use midi files? I've heard both it can and can't, but my headphones don't work.

[IceT]

I love the game so far. But the game crashes at a certain level (which is basically level 3, making it so I can't progress the awesomeness): A World One Level

This is what I encounter everytime I start the level:
Runetime error '13':
Type mismatch

(Like a dumb, I typed 'mismatch' first.. didn't work out)

I found this topic at supermariobrosx.com discussing the runtime errors in general, and a guy named bossedit8 answered with:

Type Mismatch is often referred to a code that does not fit or has decimal codes/numbers into it. Inside the Level's Folder, are there any NPC Codes that are correct to match the Level? Check to every NPC Codes that does not fit or has decimal codes/numbers into it and fix/delete them.

Seeing as everyone is having fun with the game I figured that not to be the case, so here I am asking (hopefully at the right thread, if not: sorry!) you all. Could anyone please help?

I ran the vcredist_x86 file already, installed it on another place than program files (since it wouldn't let me). Otherwise, I have no clue why this is occurring.

[Joseph Staleknight]

You did check if your computer's decimal system runs on the European system (1.234,56), right? That issue pops up a lot on computers that use that notation, since SMBX prefers the American system (1,234.56). Basically, you should swap the decimal and thousands separators in your Regional settings so that the latter notation is used, otherwise SMBX will panic and hide in the corner like someone who just saw Slenderman brush his nonexistent teeth.

EDIT: Or you can go to the offending level's folder, open up all the "npc-xx.txt" and/or "lunadll.txt" files and replace every decimal point with a comma, but that's more tedious since I imagine a lot of levels use periods to separate decimals in their text files. Hope that helps!

That issue pops up a lot on computers that use that notation, since SMBX only uses the American system (1,234.56). Basically, you should swap the decimal and thousands separators in your Regional settings so that the latter notation is used, otherwise SMBX will panic and hide in the corner like someone who just saw Slenderman brush his nonexistent teeth.

That would make sense. That could mean SMBX would parse "1,234.56" as a string, and thus shout "NOPE" and hide in a hole.

Thanks! I did not check that one, and I'm on a European system xD

*And it works! Just had to change decimals from , to . like you said.
