You can use SetVar to create your own variable and increase it based on a condition. You can then use that variable as a condition (if it's greater than 6, move a gate out of the way or something) with IfVar.

Would it be saved in the save file? And if so, would it be possible for there to actually be a modified "you need x stars to open this door" message?

[Kil]

You can't save it, so it would reset when they closed the game.

[Mabel]

Alright that will probably cause lag, for just one reason

Trigger,0,1000,0,0,0,0
[...]
ShowText,0,400,150,3,200,

Trigger is infinitely creating text that shows for 200 frames. That means the game will start to draw new text before the old text is done displaying - eventually all that text over itself 200 times per frame. Text command is slow enough to cause lag when there's that much actually. You'll start to get lag when you have over a hundred text commands printing at the same time. It should work fine if you change the time of all the show texts to 1

oh whoops, I forgot I didint need those texts anymore, guess ill remove them...

doesnt fix allowing multiple timer loops, however... :(


edit: holy crap I suck I left the trigger in #0 no wonder it never stops

Both loops work now, but How do I stop the first one?

What I was talking about was an actual game structure. I guess this is impossible? If so, thanks for answering anyways.

You can't save the stuff so it's pointless to try

[Sturg]

Sorry if this has been asked before, but is it possible to change a certain lunadll event once an npc has disappeared globally?

What I'm trying to do:

So I have a SHOW TEXT command immediately at the beginning of the level in Section 1 which goes away after time, is there some way for that text to not show up once the mid-point has been reached and deleted in the same section, and after when a player has died and starts the level at the mid-point (not sure if that's global)?

[Kil]

You can do it, the question is whether or not you find it worth the effort for that

First you need to change your ShowText command to be under a custom event, so it can get triggered by an IfVar.

#0
// If variable SturgMIDPOINT equals 0, then call the event to show the text
IfVar,0,0,0,2000,0,SturgMIDPOINT

#2000
ShowText, put your showtext stuff here
DeleteEventsFrom,2000,0,0,0,1,0

DeleteEventsFrom is there to delete #2000 so the text doesn't repeat forever.


So the new way your text is displayed is based on the SturgMIDPOINT variable. FInally, you need to set SturgMIDPOINT to 1 when you actually get the midpoint so the text will not show again.

You can either use TriggerZone to put a rectangle around your midpoint (hard if you don't know how) or use IfNPC to automatically detect when the midpoint sprite no longer exists in your level

#0
// Call event 2001 when NPC ??? no longer exists in the level
IfNPC,???,2,0,2001,0,0

#2001
// Set the SturgMIDPOINT variable to 1, inadvertently stopping the text in #2000 from showing
SetVar,0,0,1,0,0,SturgMIDPOINT

Change ??? to the NPC number of the midpoint sprite. I don't know what it is off the top of my head (this is why I hate NPC numbers)

[Grounder]

that would be 192

[TiKi]

I would like to note for posterity that changing NPCs to a checkpoint or a SMW star doesn't have any effect - the stars just don't register on your counter, and the midpoints don't register as a midpoint - even if your changed npc is the only checkpoint in the level. You could use that property to make the tape on the left direction, and a "helper mushroom" that makes small demo large on the right side, an simply change a right-facing npc to 192

I suggested this a few pages ago, there seems to be some data in the save file format that corresponds with unused player memory (like +0x1E and +0x2A). In theory, those addresses could be used for limited persistent storage.

I was having a lot of trouble with LunaDLL at the time (I think I was having the same issue as Hoeloe, outdated copy) and I got hung up on an overly-complex safety net thing, so I never did get around to testing this method myself. I still think it's worth looking into.

[Kil]

Oh yeah... I forgot all about that. But I can't test it myself right now, because I'm in between massive updates and lunadll is broke for me atm.

[Rixithechao]

Ah, sorry, didn't mean it like that. I was suggesting TiKi try it out.

[Hoeloe]

(I think I was having the same issue as Hoeloe, outdated copy)

I'd appreciate someone pointing me to a copy that isn't outdated, as I'm currently using the one from the A2MBXT devkit.

[Kil]

you're gonna need the one docopopper posted somewhere in the other thread recently (really precise location I know)

[docopoper]

Well if you have one slot for a variable in the save file format then I suggest you use it as a number that indicates which save slot you are using and use that to reference a separate file where you can save as much data as you want.

You could make it so that whenever a level is loaded LunaDLL checks whether that memory location is assigned to whatever its default value is. If it is then you start looping up the numbers checking if LunaSave1.sav exists, LunaSave2.sav exists... And once you find that a save file called that doesn't exist you set the memory location to that number. If the number isn't its default value then you know that that was the save file you used last time and it is what you should therefore use this time.

Once you have done that (still prior to level load here) then you need to have a variable that determines whether you have loaded already (this variable should not be saved). If that variable is false then you need to load from the file.

If that variable is true then you know that you need to save at a logical time (I guess this could be whenever the player returns to the world map or something if you can't make a hook for when the rest of the game is saved).

Also I think my version of LunaDLL should be in the latest devkit.

Here's the save file format btw:

So, I tried that one, and it did change the behaviour. Now, though, it doesn't work for different reasons.

Code: Select all

#0
OnInput,0,1,0,1000,0,0

#1000
DebugPrint,0,0,0,0,0,0
#END

Previously, the second event would never execute regardless of what I did. Now, it executes continuously regardless of what I do. I'm trying to make something happen when I press a button - is this the way to do that, or have I done something wildly wrong?

[Kil]

Try DebugPrint,0,0,0,0,1,0

[Hoeloe]

Try DebugPrint,0,0,0,0,1,0

It appears once at the start, then disappears immediately. For some reason it seems to be registering the event at the start of the game, and not when I press the key.

[TiKi]

Would there be a way to "enable" toad and peach to ride Yoshi?

[Kil]

no

[Grounder]

Weeeeeell, technically you could Peach/Toad/Link graphics over Mario/Luigi, but you'd have to justify the different physics and inaccurate hitboxes.

[TiKi]

no

I see. Sorry for the admittedly silly question but I'd gotten into a debate about whether or not it was a good idea to use Yoshi gimmicks in a Mario/Luigi/Toad/Peach project with another guy, so I was wondering if lunadll could solve that. I guess not!

I've saw another post about how lunadll could make a unique game, and I was wondering; can lunadll be used to change hardcoded graphics per level?

I'd also like to thank you for making this and teaching me how to use it. It's practically saved my bacon on the custom boss front - you'd be surprised to see how much changing one npc to another and setting HP can change a boss. I've even made a Tryclyde over Larry by making him not move and change back to his out of shell form when hit! Making the bosses not go into their shells almost seems like this could be a great ultimate noob boss type thing for SMBX!

No idea

[TiKi]

How would I make a custom cheat setting the "saving after cheats" value to "allow saving"? I tried to, but I couldn't get it to work.
