LunaDLL/LunaLUA help thread

Wait if smbx already saves these memory locations then this should already be working. You should be able to set those values using lunadll and smbx will handle saving and loading them.

[Rixithechao]

You said "if they're truly 100% unused", so I was concerned about the possibility that the game could still write to those addresses even if it's not reading them. If that's the case then it'd be best to store the data somewhere we know the game won't access and just use those memory locations for saving and loading.

But yeah, it's entirely possible that this whole convoluted scheme is completely unnecessary, or that it wouldn't work anyway. Instead of blathering on about it here I really should just go and try it out already.

[Kil]

i did find a couple of weird memory locations that seemed untouched in the player memory. It all depends on if SMBX saves and loads them automatically. That's one thing I never tested about them.

[Joseph Staleknight]

Is it possible to trigger events on a player's death? I've been trying to find out how that's possible, and the closest I got was seeing which address had the player's death state (0x13C) and trying to use OnPlayerMem on it.

[Kil]

That is how you do it yeah.

I think it's -1 when the player is dead.

[TiKi]

How would I go about letting some event (OnPlayerMem) trigger another LunaDLL event? I know they're some number, but how do I find the number of a certain Luna event?

[Joseph Staleknight]

That is how you do it yeah.

I think it's -1 when the player is dead.

Okay, I tried that, but when I kill the player my custom event doesn't seem to trigger. For reference, here's my LunaDLL code:

Yes, I tried using OnPlayerMem for blocks 0, 1, and 1006. I don't think any of them fired.

[Kil]

I dunno what's wrong with that but I thought of probably a better way. Near the state memory there is actually a death timer which is better understood. The fire condition can be "if death timer is greater than 0"

OnPlayerMem,0x13E,0,1,1007,0,w

[Kil]

Not sure what you mean. Whatever #number you give your custom event, that's the number you use to trigger it.

OnPlayerMem,0x13C,-1,0,1007,0,w
will trigger #1007

Okay, that works better. Thanks!

Do LunaDLL custom cheats activate the "YOU HAVE CHEATED NO SAVING" mode that normal cheats do?

[TiKi]

Not sure what you mean. Whatever #number you give your custom event, that's the number you use to trigger it.

OnPlayerMem,0x13C,-1,0,1007,0,w

Thanks! But I mean, how do I know that a certain event is say, 1007 instead of 1008?

Well, you made it under #1007.

[Joseph Staleknight]

Okay, another quick question. I've figured out how to represent the different powerups/status effects in the pseudo-RPG UI I made for the same level I had previous problems with, and now I'm attempting to record the different mounts and their colors under CP. However, in testing my level I run into overflow lag when I enter a mount other than the clown car. Is there a way to get rid of the overflow and keep the differing CP values, or should I just not care about mount color?

Here's some code again for reference, this time with helpful commentary:

oh my god what

I'm not sure what's causing lag. All your text seems to have the right amount of active time, which is 1. Keep in mind showtext is by far the slowest command, except blocktrigger or NPC commands in levels with thousands of NPCs and blocks. Showtext manually calls SMBX's incredibly bad and slow text printing command. With the luna debug thing going also, it's a lot of text being printed every frame. Maybe send me the level.

[Joseph Staleknight]

Okay then. Normally I'd wait until my level has at least a basic path from start to end before posting it, but since this is really bugging me I might as well show what I had in mind so far.

Here's the level, complete with LunaDLL document. Make of it what you will.

[Kil]

Oh

It's event #1016.
OnPlayerMem,0x10A,1,0,1017,0,w
OnPlayerMem,0x10A,2,0,1018,0,w
OnPlayerMem,0x10A,3,0,1019,0,w

Since you call this event each frame when you have a mount, keep in mind, it's copying these 3 each frame, and they all have an infinite lifecycle of 0. Change them all to 1 and it works fine. They'll all 3 die and be replaced every frame so long as you're in the mount. That goes for the ones in #1021 as well.

Basically you have 2 kinds of sensors here. The OnPlayerMem's that are called only once (1, 1000), they should be 0 to stay around forever. The other ones are constantly being copied from their custom event every frame, and they NEED to die, so they should have a time of 1 frame.

TLDR just replace those two events

Also what in god's name is going on here...

[Joseph Staleknight]

Ah, so that's what's causing the issues! Custom events are so screwy...

Also what in god's name is going on here...

Just some experimentation with the capabilities of LunaDLL for a level based on the game OFF. I'm planning on simulating the latter's battle screen UI to extend the homage.

[Kil]

Yeah I should really make it more clear to all users that custom events technically work by copying the commands in the custom event into section 0, and through that copying, any of those commands that have infinite length instantly cause massive overflows because they never go away.

[TiKi]

How does replacing one npc with another (such as npc-30 with npc-127) work?

[Kil]

You pretty much just use NPCMemSet and memory offset 0xE2

Code: Select all

// 0x+E2	w	= Sprite GFX index   // x011C = lakitu

to find any NPC with ID 30 and change it to 127

Code: Select all

NPCMemSet,30,0xE2,127,0,0,w

yeah:


coulda sworn this was used for the Nevada battle but nah that was just npc and graphic shenanigans
