Need help with lua? - LunaLua General Help

[lotus006]

When trying to start SMBX with LunaLua I get this error message:


Here are my computer specs:


I tried to search the forums if anyone provided a solution but didn't find anything.

it's happening often to me, I forgot always to activate the peripherical sound, it's probably deactivated on your side, try first to plug headset to see if change !

there's probably leftover semicolons somewhere in smbx\sounds.ini

I was trying to write custom api code which would add hp system for player (do not read the code if you don't want to get cancer).

I wrote this code but it doesn't seem to work...

Code: Select all

--HP System (by DeMuZ)---
---------------------------------------
local demuz_hp_system = {}
local max_hp = 3
local hurt = 0

local mushrooms = NPC.get(9,-1)

local encrypt = loadSharedAPI("encrypt")
hpData = encrypt.Data(Data.DATA_WORLD,true)

---------------------------------------------------------------------------------
function demuz_hp_system.onInitAPI()
	registerEvent(demuz_hp_system,"onStart","onStart")
	registerEvent(demuz_hp_system,"onTick","showHP")
end

function demuz_hp_system.setAmmount(value)
	if value > 0 then
		max_hp = value
	end
end

function demuz_hp_system.onStart()
	if hpData:get("hp") == nil or hpData:get("hp") == 0 then
		hpData:set("hp",1)
		hpData:save()
	end
end

function demuz_hp_system.showHP()
	Text.print("HP:",0,16)
	Text.print(hpData:get("hp"),64,16)

	if player:mem(0x13E, FIELD_WORD) > 0 and hurt == 0 then
		hpData:set("hp",0)
		hpData:save()
		hurt = -1
	end
	
	if hurt == 0 then
		if player:mem(0x122, FIELD_WORD) == 2 then
			hpData:set("hp",hpData:get("hp")-1)
			hpData:save()
			hurt = 1

			if player.powerup == PLAYER_SMALL and hpData:get("hp") > 1 then
				player.powerup = PLAYER_BIG
			end
		end
		
		???
	end
	
	
	if player:mem(0x122, FIELD_WORD) ~= 2 and hurt == 1 then
		hurt = 0
	end
end

return demuz_hp_system

I don't know how to make hpData rise while getting a mushroom if the player is already big.

Would anyone consider helping me?

I would suggest taking a look at HUD of Time, it's a library that adds extra health and rerenders the HUD of certain characters.

I would like to make a hp system for Mario/Luigi and HUDofTime.lua seems to work only with Link.

If I can't create that with HUDofTime.lua, the only thing I need is to make "trigger lua code by getting a mushroom even if the player is big"

[PixelPest]

Yes, but take a look at what it does and see if you can apply it to what you're trying to do

[DeMuZ]

Yes, but take a look at what it does and see if you can apply it to what you're trying to do

HUDofTime.lua uses SMBX hearth system to check if it should increase or decrease the ammount of player's hp variable, so it's only possible to use this code for Toad, Peach and Link.
I would like to apply hp variable system to Mario/Luigi, too. :/

EDIT: I think i can make it with onNPCKill() function but I don't know how to use it. I always get this error:

Can you post the code (or the code snippet) at line 38?

[DeMuZ]

Can you post the code (or the code snippet) at line 38?

Code: Select all

function demuz_hp_system.onNPCKill(<i don't know what to put here>,NPC.get(9,-1),9)

[Kevsoft]

Yea... classical misunderstanding. So the thing is that events will pass you already defined values. You have to name those arguments a specific names.
So

Code: Select all

function someAPI.onNPCKill(eventObj, npcObj, npcKillReason)
    if npcObj.id == 9 and npcKillReason == 9 then
        <do your stuff here>
    end
end

is the correct code.

[DeMuZ]

Thank you for help!

EDIT: Why is this code not working? Player falls under the screen when he gets hit.

Code: Select all

function demuz_hp_system.showHP()	--onTick
(...)
	if hpData:get("hp") > 1 and player.powerup ~= PLAYER_BIG then
		player.powerup = PLAYER_BIG
	end
(...)
end

notice me (any) senpai :>
I wanna finish my episode before September.

Try having this offset activate whenever the player gets hurt.
player:mem(0x122,FIELD_WORD,12)

[PixelPest]

Try having this offset activate whenever the player gets hurt.
player:mem(0x122,FIELD_WORD,12)

So what's your issue? You can check if player:mem(0x122, FIELD_WORD) == 2 (player is powering down) if that's what you're wondering, but I really don't know what exactly you're asking

[Emral]

Thank you for help! :)

The player's hitbox changes because it loads the hitboxes for small mario. Since the hitbox's origin is at the top of the player, they get gradually pushed downward with each back-and-forth.
You need to offset the player by the difference and make sure to reset offset 0x122
http://wohlsoft.ru/pgewiki/SMBX_Player_Offsets

Try having this offset activate whenever the player gets hurt.
player:mem(0x122,FIELD_WORD,12)

When the player gets hurt, 0x122 gets set to 2. Setting that state to 12 will NOT give the player a hammer suit, btw.

Try having this offset activate whenever the player gets hurt.
player:mem(0x122,FIELD_WORD,12)

So what's your issue? You can check if player:mem(0x114, FIELD_WORD) == 2 (player is powering down) if that's what you're wondering, but I really don't know what exactly you're asking

No. No. No. No. No. No. No. No. No. No. No.
0x114 is the displayed sprite index. Do NOT check for 0x114 in this scenario.

Don't do this.

[PixelPest]

Oops. I meant 0x122. Just didn't have the documentation open and mixed them up

[Yoshi021]

No, I used to have the same error that DeMuZ had where the player will move under blocks when you get hurt, but by having the Hammer Suit effect happen when the player gets hurt fixes the error. My intention was never to give the player the hammer suit.

[DeMuZ]

Code: Select all

player:mem(0x122,FIELD_WORD,12)

Adding this code actually helped!
Thank you for helping me! Now, with more hp, Mario will be happy!

Is CaptureBuffer no longer a function or something? I keep getting a nil value every time I try to call it:



The code is literally just: local buf = Graphics.CaptureBuffer(800, 600)
