LunaLua Offical Thread - SMBX Usermod Framework

[Artix3]

Out of curiosity, is there a way to check "if playing"? Trying to use onLoad() and I've had it crash when I load the level in question in the level editor. Being able to add an "if game is running" conditional would help a lot there.

[Kevsoft]

Maybe try onLoadSection0.

[lighthouse64]

local g = 3
gravity(g)
onJump(g=g*-1)


I changed it up a bit, but it still shows an error.

Use defines instead: http://engine.wohlnet.ru/pgewiki/SMBX_Fields
Also, you're mixing up events with functions, declaring function ALWAYS works like that:

Code: Select all

function onJump()
...
end

In your case:

Code: Select all

function onJump()
   Defines.gravity = Defines.gravity - 1
end

How do you change the grab offset of characters? I want to make Mario hold objects above him, how do I do it?

Oh. I get it now Because last time I didn't understand, but it all makes sense now. Thanks Kevsoft!

But I'm just wondering, does lua do negative numbers?

Use calibration tool (open one of "grabbed item" frames and do your modifications) and save the INI file which will define than, when you need to apply than INI file by onLoad() function:

Code: Select all

Level.loadPlayerHitBoxes(int characterId, int powerUpId, string iniFilename)

When I try to open the recent version, I get a message error about KERNEL32.dll (I guess it was "The procedure Entry Point GetThreadId could not be located in the dynamic link library KERNEL32.dll", not sure because my system is in portuguese). Is it possible to fix?

Do I use a lunalua or text file?

Crap, you probably use something like Windows XP? I have to fix that!

Why shouldn't it ?

[PersonNamedUser]

I'm putting in this code:

Code: Select all

function onLoad()
    -- ....
    Level.loadPlayerHitBoxes(1, 1, "mario-1.ini")
end

And it won't work!

Are you put mario-1.ini file into custom level folder? I think, you doesn't made it. You need to use Player Calibrator to setup hitbox with settings

[PersonNamedUser]

Never mind now it's working!

[PersonNamedUser]

With Lunaworld Do you need mario-1.ini for every level?

Can you help me change the character hit-box? I tried to change buzzy beetle's Hit-box but he go in the ground instead of standing on-top of it like he should, I need help with hit-boxes.

Well look on the sprite sheet, there is a gap at the top above Buzzy Beetle. To make the hitbox right you have to move each of his sprites up.

[Fennor]

Usually the player graphic overlaps by two pixels with the ground. So if you have a frame with a hitbox height of 30, your graphic should have a height of 32 pixels and begin at the very top of the frame/y=0 (I mean as FanofSMBX said, you have to move them up. The whole sheets have a height of 1000 pixles, each frame has 100 pixels. So the top of the first frame is at y=0, the second at y=100 and so on).

You also have to consider the yOffset of the hitbox. Let's say the hitbox height is 30, the yOffset is 2, (Keep in mind that you currently can't change this offset) in this case your graphic should have a height of 34 pixels and begin at the top. The first 2 pixels (y=0 and y=1) of the graphic won't be part of the hitbox due to the yOffset, it moves the hitbox down by 2 pixels. The next 30 pixels (y=2 to y=31) of the graphic will be part of the hitbox. The last 2 pixels of the graphic (y=32 and y=33) will overlap with the top of the floor and aren't part of the hitbox.

EDIT: More about offsets. If you have an yOffset of 2 but don't want the hitbox to begin at the very top - not just 2 pixels down from the top - you can increase the hitbox height by 2, but at the same time move the graphic 2 pixels down. The graphic will still stand on the ground correctly, but at the same time the top of the graphic will be part of the hitbox.

So, it's going to be fixed in the next version?

[Kevsoft]

Yes, it should be already fixed, but there is still another small issue, that have to be fixed, before the hotfix will be released.

[PizzaLover]

Hello everyone. I'd need some help with code: is it possible to make section 3 in my level so player and npcs in there fall slower? Thanks
