How does one change the amount of hits that it takes to kill a 'boss' npc?

Hey, is there any way to turn off the cinematX HUD in a level that uses cinematX?

If you're using an old version of cinematX, no.
If you use a new enough version of cinematX, this is off by default actually, but you can turn it back on by calling cinematX.config with "true" as the third argument.

Take a look at line 1679 of cinematX.lua's current version.

[Rixithechao]

Alternatively, you can just set cinematX.useHUDBox to false in the newer versions.
config() is going to be deprecated. The absolute latest version, which I haven't committed to github yet, has a better config function that uses named arguments. Same thing with configDialog() and startDialog().

So I gotta be missing something with loadAnimatedImage...
Using Graphics.loadImage("Example.gif") works (and I can draw the first frame of the gif using both drawImage and placeSprite) but Graphics.loadAnimatedImage("Example.gif") gives me an seemingly empty table, what the heck? Tested two different animated gifs with the same result

I could also be missing some easier way to import custom animation without repurposing npcs...

Edit: I missed that loadAnimatedImage returns multiple values, doh.
Edit2: But still doesn't change that the table I get is completely empty GAAAAH FRUSTRATING.

I'm trying to use multipoints and I'm noticing that npcs aren't already spawned when I reenter the level after getting a multipoint. What's happening?

You have an old version of multipoints I'm guessing. This was a bug before version 3.0.10. 3.0.11 is the most recent version.

In my level I was able to turn the detonators into pseudo P-switches, and they have a little custom tune that plays when the switch is pressed. Would it be possible to lower the volume of the background music while this happens? Both the start and the end of the P-Switch time are activated via SMBX events, so onEvent triggers could be easily utilized.

[SAJewers]

Note that we have plans to imeplement ASMT's ticking P-switch thingy, so you may not need to do it yourself.

After looking around some of the LunaLUA tutorials, I found out how to change the music volume with LUA! ^_^ Though, I don't know what the default volume level is for SMBX music.

Default SMBX Music volume is 0.4 (400/1000 by MCI volume scale), so: 128*0.4=51.2 -> 51 - value for a music volume function.

Excellent, it works perfectly! Thank you! :)

Does anybody have a functioning Multipoints Lua code I can look at? I just don't understand the tutorial on the PGEwiki and searching this thread isn't bringing anything up. I've tried using the search terms checkpoints, check point, multipoint, but to no avail.

Also, is there a way of forcing a layer to display above another? Ever since I converted a bunch of layers to PNG, they display strangely both in the SMBX Editor and the PGE editor.

There are a few A2XT levels that use multipoints. Descent of Nine and What's About Railways? both use it.

As for making a layer display above another, that's sort of not what SMBX layers are. "Layer" is a pretty poor term to be honest, as they're more like named groups. You can display Lua-drawn graphics with a specific order using the "WP" drawing commands, but otherwise you're stuck with using foreground objects.

Ah, that's great. I'll have a look at those two. Thank you.

They're all foreground objects. I'll concentrate on multipoints for now.

EDIT: Whilst i'm at it, I might as well review your level.

Does anyone know how to do autoscrolling with LunaLua? I know exactly how to do it with LunaDLL Autocode (use the PushScreenBoundary function), but I'm not sure what the equivalent in LunaLua is. I tried getting the boundary and setting the border values, but nothing sticks. For example, this:

Code: Select all

function onLoop()
	local sec = Section.get(1);
	Text.print("before: "..tostring(sec.boundary.right),0,64);
	sec.boundary.right = -19922;
	Text.print("after: "..tostring(sec.boundary.right),0,80);
end

doesn't actually change the right border position. I feel like I'm missing something obvious...
I'm using LunaLua v0.7.2.2.

[Rednaxela]

I feel like I'm missing something obvious...

I'm guessing the mistake is most likely that you're wanting to set this in what the editors call "Section 1". Getting the first section in LunaLua is Section.get(0), not Section.get(1)

No, that's not it; when I use Section.get(0), I get an error message telling me to use a number between 1 and 21. Even then, I feel the code should work regardless of the section the player is in.

[ztarwuff]

I'm not entirely sure what's happening but my third Lua Checkpoint isn't triggering in my level: Gravity Falls. Would anybody be able to help me in figuring out why?

Granted, there's an axe in the third location, but there's an axe in all three locations. (It's there to reset the layers).

Code: Select all

multipoints = loadAPI("multipoints");

--Section 5 Checkpoint Bottom of Vertical Shaft
multipoints.addLuaCheckpoint(-119935, -120063, 4);
--Section  9 Empty Room
multipoints.addLuaCheckpoint(-39952, -40062, 8);
--Section 12 Before Boss
multipoints.addLuaCheckpoint(-20065, -19937, 11);

I'm having some trouble getting my filter to work. SAJewers gave me the code, and I put it in a text file, but when I play the level through the editor, it doesn't seem to make me that character. Anybody know what I might be doing wrong?

I don't know what your specific code is, but something like this should work to force a character:

Code: Select all

function onLoad()
	Player(1).character = CHARACTER_PEACH;
end

Or alternatively, if the previous code gives you an annoying invalid-player-pointer window thing:

Code: Select all

local iniDone = false;
function onLoop()
	if (not iniDone) then
		Player(1).character = CHARACTER_PEACH;
		iniDone = true;
	end
end

This was the code that SAJewers gave me:

Code: Select all

function onLoad()
   if (player.isValid) then
      player.character = CHARACTER_TOAD;
   end

end

It could be very possible that I'm not putting it in the right place or something, but I put my txt file in the general folder where the level is and the folder where the music is, and neither of them worked.
I'll try your examples tomorrow.

If you level file is "worlds\episodeFolder\myLevel.lvl", this should be in the file "worlds\episodeFolder\myLevel\lunadll.lua"
The fact that you say "txt file" makes me wonder if you have a .txt extension when you should have a .lua extension perhaps also.

How would I make it a lua extension? That's probably it.

      player.character = CHARACTER_TOAD;

end

Try replacing the two "player" with two "Player(1)", maybe.

edit:

Open notepad, paste the code and it should give you the option to choose the extension you want when you "Save As".
