[tall horizon]

what does slot_datas return?

[neon dagger]

is there a way to print without compiling? error prevents compiling

@export var slot_datas: Array[SlotData]

[tall horizon]

it needs to compile to run. try taking out the type annotations (the : Type bit). that should get it to compile

[neon dagger]

this one? inventory_data: InventoryData

[tall horizon]

which ever is causing the compile time error

[neon dagger]

i dunno, I just pressed undo until it stopped doing the error

maybe the tutorial has an error in it

[tall horizon]

I remember helping someone else a bit ago who used this tutorial, so it could be that

[neon dagger]

@tall horizon the tutorial removes the 3 lines here but when I do it, I get an error https://youtu.be/V79YabQZC1s?t=2113

@muted fiber it's here

[tall horizon]

watch a bit farther. it fixes it

[neon dagger]

oh okay

not for me it didn't

he compiles right after this and it's got an error for me

[tall horizon]

check the inventorydata.gd script. it could have an error

[neon dagger]

my indents were messed up

i was in the inventorydata.gd script

but yeah, it crashed when I dragged the two slots together for some reason

[tall horizon]

SlotData doesn't have item. did you miss type it?

in SlotData

and why do all those lines end with \?

[neon dagger]

I don't know, I was copying the video

[tall horizon]

apparently that tells it that the boolean expresion continues on the next line. I didn't know that was a thing

[neon dagger]

which line?

line 5 or line 10?

oh line 5 isn't visible

[tall horizon]

you are looking for a property called item on a SlotData on line 11. try using itemdata

[neon dagger]

huh, that works

thanks

maybe I mistyped it

[tall horizon]

whoever made this tutorial needs to stop using lower extruder case for properties

[neon dagger]

what's lower extruder case? like snakecase?

[tall horizon]

lowerextrudercaselookslikethis

snake_case_is_this

andThisIsCamelCase

snake case is standard for properties in godot. I have no idea why the tutorial author thought lower extruder was a good idea. it's basically unreadable

stuck again, the inventory won't give control of the mouse back

so i can click the chest I made

the inventory uses a keypress to interact with the chest but my game is 2d and mouse controlled

[narrow locust]

Hi, I didn't see that video, do you mean, you can click what that is behind the inventory(like chest) if yes, then you must deal with the 'mouse filter'

[neon dagger]

I'm getting help with it

the canvaslayer was blocking it
