Need help with lua? - LunaLua General Help

Player runspeed is capped. Walkspeed isn't.

If Walk speed isn't capped, then could I force the player to use walkspeed?
Also, isn't player.get() static? Wouldn't that mean an error would be brought up if I did this?

Code: Select all

playerTable = player.get;
playerTable[1].spinJumpKeyPressing = false;

Edit, i tested it and it did nothing, so either it ignores it or sets it properly

walkspeed is used when the run key is not held, while runspeed is used when the run key is held. For solutions, refer to my previous post.

Have you used NPC.get() before in order to loop over NPCs? It's used like that.

Code: Select all

for k,p in ipairs(Player.get()) do
	p.altJumpKeyPressing = false
end

Few notes on that code:
- it's altJumpKeyPressing, like seen on this page https://wohlsoft.ru/pgewiki/Player_(class)
- Player.get() is a method static to the player class, yes. This means that while Player.get() exists, player.get() does not.

Another question is, can we use different plugins like LuaSocket? I want to use a timer without a busy wait but you need something external to do that.

... what is your goal?
A timer is just a variable you tick up in onTick.
A leveltimer can be implemented using timer.lua, for which there are instructions on the handbook.
What do you mean by "busy wait"?

By busy wait I mean it stops everything, i.e. freeze the game, which I don't want.

A timer is just a variable you tick up in onTick.

How many ticks would be in a second? I don't want to have to use ticks because I'm not very familiar with that.

It also looks like I can't use the command line to sleep because that raises an error when I use os.execute().

Here is what I want to do:

64.12 frames in a second. That's how often onTick runs. 39/2500 seconds per frame, to be precise.

First of all, I recommend using the "keys" fields. Your player here is x so it'd be x.keys:
The below line is true only on the frame on which the alt jump key is pressed:
if x.keys.altJump == KEYS_PRESSED then

You can also use x.mount < 1 instead of the mem offset.
I don't know what c is in this context because of this heavily cut down code fragment, so I can't comment on that bit.
Next, I don't know why you would want to wait a frame in that situation. It sounds rather volatile/unresponsive. It looks like you're trying to make a long jump script, but long jumps have never been locked to an arbitrary 20 frame limit, or with a 1-frame delay.
Then again, very little context in this script so I cannot give more precisely targeted advice regarding the intended goal. Dunno the intended goal after all.
The easiest way to delay by 1 frame is by using a coroutine https://wohlsoft.ru/pgewiki/EventU.lua
You never have to use io or os functions when working with SMBX2's lunalua module.

I think my stuff is working with nothing really messed up, so I think I'm done with the help.
I'll probably post the file soon to the forum

[FlyingGym]

So https://wohlsoft.ru/pgewiki/PowerUDFreeze.lua is deadlinked, any way to replicate it?

[MarioLover64]

is it possible to use my system's date to do stuff on specific days?

os.date is available, so yes.

[MarioLover64]

ok so camLock refuses to work at all. it does absolutely nothing. There aren't even any errors.

Added in 36 seconds:
Oh yeah, here's my code
--------------------------------------------------
-- World map code
-- Created 12:47 2019-5-3
--------------------------------------------------

-- Run code on first frame of the world map
function onStart()
local camLock = require("camLock")
camLock.addZone(-64,0,25,20)
end

-- Run code every frame (~1/65 second)
-- (code will be executed before game logic will be processed)
function onTick()
--Your code here
end

[Emral]

You're creating a camera zone at coordinates -64, 0 with scale 25, 20. That's 25 pixels wide and 20 pixels tall. You expect the camera to fit in there? The camera is 800x600 pixels...

[MarioLover64]

i thought it was a per tile basis

[Emral]

Struggling to think of a scenario where distance in lua libraries isn't measured in pixels.

[MarioLover64]

me adjusts so it's big enough



Still doesn't work

Code: Select all

--------------------------------------------------
-- World map code
-- Created 12:47 2019-5-3
--------------------------------------------------

-- Run code on first frame of the world map
function onStart()
    local camLock = require("camLock")
 	camLock.addZone(-64,0,864,800,1)
end

-- Run code every frame (~1/65 second)
-- (code will be executed before game logic will be processed)
function onTick()
    --Your code here
end

Seems there is an issue with camlock on the PAL release, odd.
Try Beta 3. It should work there.

Been looking to figure out how to use the darkness.lua and attach a light to an npc (npc-102 to be precise) but can't figure it out for the life of me. I only figured out how to do so editing the darkness.lua script directly. NPC.get keeps giving me arithmetic errors.

Use the NPC config flags:

How can I make it so that enemies thrown at a boss only damages the boss if it hits the top 32 pixels of the boss and just kills the thrown npc otherwise.

How do I make noteblocks bounce me higher (to a height of six blocks instead of five)
