I tried to load a font from this page, specificaly the Superstar Saga one and then I got an error.


I am using this code to load it:

Code: Select all

textplus.loadFont("Fonts/superstarsaga-b.ini")

I also tried placing it in the root directory and ommiting the "Fonts/" and it still didn't load. What am I doing wrong?

You need to use Misc.resolveFile on the path.

Also, to solve Baemajinn's question while I'm at it:

This is not an answer to that question. Those are just the constants for the score popup effect.

The real answer is to use Misc.score(newScore), as documented here: https://docs.codehaus.moe/#/reference/misc

Okay, now I have loaded the font through Misc.resolveFile and no more errors! The font hasn't loaded though. Is there anywhere in particular I need to put the textplus.loadFont? Currently, it's right below the Misc.resolve file, as seen here:

Code: Select all

Misc.resolveFile("Fonts/superstarsaga-b.ini")
textplus.loadFont("Fonts/superstarsaga-b.ini")

Yeah that's not how that works. Misc.resolveFile returns a string. You're doing exactly the same thing you were doing before, because you don't use the result of Misc.resolveFile anywhere. You need to put that function call instead of the file path when you try to load the font.

You also need to store the font you load in a variable.

Aaaaaaah, this really should be in the doccumentation. I assume it is loaded like this?

Code: Select all

fontB = Misc.resolveFile("superstarsaga-b.ini")

But when I load it like this:

Code: Select all

textplus.loadFont(fontB)

I get an error. Probably because I'm still doing the same thing. That said, putting fontB ointo the tab console spits up the file path, as seen here:



I really don't get what I have to do. Would it be possible to provide the correct snippet of code for this?

It's not in the lunalua documentation because knowledge about variables is properly explained across tutorials for lua itself, and programming languages as a whole.
The documentation properly describes that loadFont returns a font object...

Code: Select all

local myFont = textplus.loadFont(Misc.resolveFile("path_to_font.ini"))

... and that the textplus's parse function lets you supply a font as an argument, and that the textplus's print shortcut also accepts all the parse parameters.

Code: Select all

textplus.print{
            font = myFont,
            text = "Hello",
            x = 460,
            y = 40,
            maxWidth = 230,
            priority = 2,
            color = Color.red,
            xscale = 2,
            yscale = 2,
        }

Oh, okay. Should I come back after learning a bit more about the language itself then?

[Goldenemerl64]

What does it mean by updating an older SMBX2b4 install? and how does it work?

[baenyth]

I tried the Misc.score(newScore) function, but for whatever reason, it didn't work. I used the function in onTick() and a coroutine if that has any effects.
I tried Score with a capital S, but that caused errors.

[DigitalDetective47]

I'm trying to script an achievement, but whenever I run the script, I get an error message. Here is my code:

Code: Select all

function onEvent(FindCave)
	local cave = Achievements(2)
	if not cave.getCondition(1).value then
		cave:progressCondition(0)
		cave:progressCondition(1)
	end
	Misc.dialog(cave:getCondition(0).value)
end

ach-2.ini contains this:

Code: Select all

name="Goomba Plumber"
desc="Find all secret caves in World 1"
condition-0=3
condition-0-desc="Find secret caves"
condition-1=true
condition-2=true
condition-3=true

and my errorlog is this:

What am I doing wrong here?

[Emral]

getCondition is also a method, meaning it needs a colon.

Thanks for the help! I had a few other fixes, but I needed this to find those issues.

[Goldenemerl64]

How do you Trigger Auto scroll on event using the Collectible Trigger?

[ShadowXeldron]

How do you spawn an item in the player's hand?

[Daring Tombstone]

Shouldn't this be working? It doesn't do anything. I've used rng before so I'm baffled why this isn't doing anything.

[Emral]

You're redefining rng by naming your function rng. Also you can just kinda use rng using the RNG namespace without loading it.

[Daring Tombstone]

I must have been half asleep or something cuz I didn't even notice I named the function rng also. Me being oblivious sorry. Thanks.

Is there any way to load a specific image for a specific chracter, I tried searching for it in the documentation but couldn't find it.

It's not on the documentation because it's not a thing. What you can do is load an image and internally structure your code so that it's interpreted as something only visible to a certain character, like indexing a table by character ID and putting objects into that element of the table, like so:
local t = {
[CHARACTER_MARIO] = { obj1 = Graphics.loadImage ... },
[CHARACTER_WARIO] = ...
}

t[player.character]returns the object at that index.

[Marioman2007]

The Code:

Spoiler: show

Code: Select all

local t = {
[CHARACTER_MARIO] = { obj1 = Graphics.loadImage(Misc.resolveFile("modernhud-2.png")) },
}

function onDraw()
    Graphics.draw{
        type = RTYPE_IMAGE,
        image = obj1,
        x = 500,
        y = 100,
        priority = 0,
    }
end

Error:

[Emral]

obj1 is part of the t table. You must access it through the table. See my previous post for reference.

I do not understand, any examples?
