I dumped all the contents in the directory but now the HUD health won't show and Temmies shop isnt working...why is this stuff so complicated...[/color]

Step by step instructions on how to install Lunalua:

If you want a separate directory:
-go to http://engine.wohlnet.ru/LunaLua/
-select full installation
-vanilla + launcher
-include complete standalone game
-create a new folder on your pc
-dump the contents of the zip into the folder
-drag your lunalua episodes into the worlds folder
-maybe update your lua
-profit

If you don't want a separate directory:
-go to http://engine.wohlnet.ru/LunaLua/
-select full installation
-vanilla + launcher
-dump the contents of the zip into your smbx folder
-maybe update your lua
-profit

Instructions on how to install the SMBX 2.0 beta are in the first spoiler of this topic:

How do you set a bosses hit points? More specifically, i'm trying to set larry koopa's hit points to 5 instead of 3 but i can't figure out how to.
Could someone please help?

Larry Koopa has 9 HP to begin with. Jumping takes 3, sword stab and fireballs take 1. Have you been to the NPC Offsets page on the wiki? It's one of the most important pages and has the field you're looking for.

...sword stab and fireballs take 1.

Actually Link's Sword can take 2 damage on Larry Koopa and Ludwig von Koopa.

How do you add in multiple checkpoints?
I'm trying to add a checkpoint with this code:

Code: Select all

function Onloop()
    tableOfCheckPoints = multipoints.addLuaCheckpoint(-159601, -160208, 3,-159601, 160208);
    for n=1, table.getn(tableOfCheckPoints) do
	    if (Checkpoint.collected(true) then
		    getCheckpoint(2)
			getCheckpointID(2)
			getCheckpointStatus(true, 2)
		end
	end	
end

Can anyone tell what code to put in to add in another checkpoint?

[HenryRichard]

I'm pretty sure it's onLoop(), not Onloop().

Also, it's absolutely nothing like what you have to do. You just put this somewhere in your code (not in a function or anything):

Code: Select all

multipoints = loadAPI("multipoints");

--First Checkpoint
multipoints.addLuaCheckpoint(-150000, -150000, 0);

--Second Checkpoint
multipoints.addLuaCheckpoint(-100000, -100000, 0);

EDIT: I'm working on an inventory that lets you save multiple items with theoretically unlimited amounts of extra data saved directly to the item. I want it to all be saved as a string. Currently it works with a space as a separator:

Code: Select all

local item = "itemId extra saved data"
	local i = 0;
	for w in string.gmatch(item, "%a+") do
		Text.print(w, 0, 0 + 16 * i);
		i = i + 1;
    end

The problem is I don't want to use the spaces as the separator, I want to use the '|' character. Try as I might, I cannot figure out how to make it work like that. Any ideas?

EDIT 2: Solved it. I replaced the "%a+" with "[^|]+".

Created custom hud

Spoiler: show

But something gets wrong & I get the following message while launching level with it:

lunadll.lua:9: 'end' expected (to close 'function' at line 6) near '<eof>'

Here is code:

Code: Select all

local coin = Graphics.loadImage("../hud/coin.png")
local xxx = Graphics.loadImage("../hud/xxx.png")
local lives = Graphics.loadImage("../hud/1up.png")
local heart = Graphics.loadImage("../hud/heart.png")
local HP0 = Graphics.loadImage("../hud/HP0.png")
local HP1 = Graphics.loadImage("../hud/HP1.png")
Graphics.activateHud(false)

function onHUDDraw()
	Graphics.drawImageWP(lives, 250, 26, 3)
	Graphics.drawImageWP(xxx, 274, 27, 3)
	Graphics.drawImageWP(xxx, 512, 27, 3)
	Graphics.drawImageWP(coin, 488, 26, 3)
	Text.printWP(mem(0x00B2C5AC, FIELD_FLOAT), 298, 26, 3)
	Text.printWP(mem(0x00B2C5A8, FIELD_WORD), 536, 26, 3)
	Text.printWP(mem(0x00B2C8E4, FIELD_WORD), 536, 46, 3)
	if(health == 0) then
	Graphics.drawImageWP(HP0, 361, 18, 3)
	Graphics.drawImageWP(HP0, 393, 18, 3)
	Graphics.drawImageWP(HP0, 425, 18, 3)
	elseif(health == 1) then
	Graphics.drawImageWP(HP1, 361, 18, 3)
	Graphics.drawImageWP(HP0, 393, 18, 3)
	Graphics.drawImageWP(HP0, 425, 18, 3)
	elseif(health == 2) then
	Graphics.drawImageWP(HP1, 361, 18, 3)
	Graphics.drawImageWP(HP1, 393, 18, 3)
	Graphics.drawImageWP(HP0, 425, 18, 3)
	elseif(health == 3) then
	Graphics.drawImageWP(HP1, 361, 18, 3)
	Graphics.drawImageWP(HP1, 393, 18, 3)
	Graphics.drawImageWP(HP1, 425, 18, 3)
	end
	if(mem(0x00B251E0, FIELD_WORD) >= 1) then
	Graphics.drawImageWP(heart, 250, 46, 3)
	Graphics.drawImageWP(xxx, 274, 47, 3)
	Text.printWP(mem(0x00B251E0, FIELD_WORD), 298, 46, 3)
	end
end

function onLoop()
health = player:mem(0x16, FIELD_WORD)
end

What i'm doing wrong?

UPD: nevermind, I fixed it.

1. How do you use the SpriteOverride class? Everytime I use it I get "attempt to index field 'sprites' (a nil value)" error.
2. How I make upside-down venus fire trap, and is it possible to put normal and upside-down venus fire trap in the same level?
3. How do I make hammer bro throw more hammers?
4. How to make a section autoscroll in the middle of the level?

[Imaynotbehere4long]

I was wondering if anyone has coded Mario-Maker-exclusive features yet, specifically using mushrooms on enemies to make them giant, Buzzy Beetle shell helmets, and Spiny helmets, or if it would even be possible to do so (and if so, how).

1. Not implemented yet, we have to wait for the update. If you want you can try the dev-build (available on the LunaLua download page), but there are often errors in it.
2. I'm not entirely sure, but with a bit of trigonometry and NPC.spawn() you could probably turn an upside down piranha plant into one.
3. ai3
4. use this and add/subtract to the x and y. There's probably a slightly better way that I don't know about.

Funny, I'm working on an API to add helmets. Mushrooms making enemies giant would be pretty easy, I'd suggest looking at the example here and see if you can turn it into a thing that makes goombas bigger when they touch mushrooms.

Can someone please help? What code do I need to make it so that the player cannot crouch?

[HenryRichard]

Code: Select all

function onInputUpdate()
	for playerIndex, thePlayer in pairs(Player.get()) do
		thePlayer.downKeyPressing = false;
	end
end

[PixelPest]

Code: Select all

function onInputUpdate()
	for playerIndex, thePlayer in pairs(Player.get()) do
		thePlayer.downKeyPressing = false;
	end
end

Thank you. That worked perfectly.

Forgive me if this sounds like a dumb question, but is any modding of netplay possible?

How can I constantly give Peach the Tanooki power-up without increasing her # of lives.
I have:

Code: Select all

function onTick()
	player.powerup = 5
end

[HenryRichard]

You could try doing something with player.Hearts. Also, it's onLoop() and not onTick().

[PixelPest]

I thought onTick() was the new thing?

So like:

Code: Select all

function onLoop()
       if player.powerup == 1 then
              player.powerup = 5
              player.hearts = 1
       end
       if player.powerup == 2, 3, 4, 6, 7 then
              player.powerup = 5
              player.hearts = 2
       end
end

TIL onTick() exists

Unfortunately, I don't think it's going to be that simple. You may need to remake the health to get it to work.

What do you mean by "remake" the health?

[HenryRichard]

Like, make a new variable for health and update it based on the player's conditions so you can make the powerup whatever you want. I'm working on a HUD that has the health redone, so when I'm done with it I'll let you know and you can look at it.
