Having issues with Ultimate Platformer Controller | Godot Engine | Page 1

Im brand new to Godot Engine and I've been trying to use this asset library but I cant seem to figure out why it's giving me a "Invalid access to property or key "scale" on a base object of type 'Nil' error

I'm not sure exactly which of the code you'd want to see to be able to help me but the debugger points out these two lines

func _ready():
wasMovingR = true
anim = PlayerSprite
col = PlayerCollider

1-> _updateData()

func _updateData():
acceleration = maxSpeed / timeToReachMaxSpeed
deceleration = -maxSpeed / timeToReachZeroSpeed

jumpMagnitude = (10.0 * jumpHeight) * gravityScale
jumpCount = jumps

dashMagnitude = maxSpeed * dashLength
dashCount = dashes

maxSpeedLock = maxSpeed

2-> animScaleLock = abs(anim.scale)
colliderScaleLockY = col.scale.y
colliderPosLockY = col.position.y

What Godot version are you using @warm tapir ?

warm tapir Nov 14, 2024, 4:02 AM

#

4.3

timid anchor Nov 14, 2024, 4:02 AM

#

And version 1.0.2 for the ultimate platform controller?

warm tapir Nov 14, 2024, 4:02 AM

#

yes

timid anchor Nov 14, 2024, 4:03 AM

#

How have you contructed the scene?

warm tapir Nov 14, 2024, 4:05 AM

#

Uhhh I have two scenes atm one that holds my character sprites+collider and another scene thats just a super basic square stage to run around in

#

If theres anything else I should mention please tell me

timid anchor Nov 14, 2024, 4:05 AM

#

It does look like there is a sample project you can refer to: https://github.com/Noah-Erz/Ultimate-Platformer-Controller-2D/blob/main/UCC Public Files.zip

Try making sure that the Sprite is called PlayerSprite (casing matters).
My guess is that you missed a $ before the node's name. It should be something like anim = $PlayerSprite

#

$ is used to tell Godot to look for a Node with that name

warm tapir Nov 14, 2024, 4:06 AM

#

thats what these are for no?

vapid whale Nov 14, 2024, 4:07 AM

#

Yes, but you still haven't set them. You could have multiple sprites or collision shapes

warm tapir Nov 14, 2024, 4:07 AM

#

oh so I have to put $ signs for all of those?

vapid whale Nov 14, 2024, 4:07 AM

#

Not in this case, because they are already exposed. Check the right sidebar in the editor

warm tapir Nov 14, 2024, 4:08 AM

#

exposed? I'm a complete baby at this stuff 😂

vapid whale Nov 14, 2024, 4:09 AM

#

When you use @export, you tell the editor to show that variable in the inspector, so you can easily fill it out

timid anchor Nov 14, 2024, 4:09 AM

#

You are exporting these

vapid whale Nov 14, 2024, 4:09 AM

#

You probably didn't choose what Sprite to use

timid anchor Nov 14, 2024, 4:09 AM

#

That implies you want to hook up those nodes via the inspector

warm tapir Nov 14, 2024, 4:09 AM

#

oh oh okay

timid anchor Nov 14, 2024, 4:10 AM

#

warm tapir Nov 14, 2024, 4:10 AM

#

Thats what makes that GUI come up when I look at the characterbody2d thingy

timid anchor Nov 14, 2024, 4:10 AM

#

It looks like you are using the sample project afterall

warm tapir Nov 14, 2024, 4:10 AM

#

Yes I set those

#

Hmmm

#

In that example right everythings in one scene

#

maybe that is it

timid anchor Nov 14, 2024, 4:12 AM

#

oh maybe you are not using the sample project, that is the one mega script that handles everything haha

warm tapir Nov 14, 2024, 4:12 AM

#

no no I am trying to use this for my own thing

#

xD

timid anchor Nov 14, 2024, 4:12 AM

#

That's fine, just trying to get context is all

warm tapir Nov 14, 2024, 4:13 AM

#

Maybe this is actually the problem then, because I've my stage and character stored on different scenes cause when I add my player node as a child scene it doesnt let me assign the character and collider nodes

timid anchor Nov 14, 2024, 4:15 AM

#

Does your player scene not have all the nodes you need to hook up?

warm tapir Nov 14, 2024, 4:15 AM

#

it does

timid anchor Nov 14, 2024, 4:15 AM

#

That should be fine then, no?

#

All the nodes are contained with the scene

warm tapir Nov 14, 2024, 4:20 AM

#

oh hmm

#

So these all show as null for some reason even though I've definitely given PlayerSprite and PlayerCollider their information and anim/col are the same as PlayerSprite/PlayerCollider

timid anchor Nov 14, 2024, 4:27 AM

#

What does your scene look like?

warm tapir Nov 14, 2024, 4:28 AM

#

very basic atm

vapid whale Nov 14, 2024, 4:30 AM

#

I think you didn't set the Nodes in the player scene, but did set them in other scenes?

#

Wait, no

timid anchor Nov 14, 2024, 4:30 AM

#

Can you scroll this all the way down?

vapid whale Nov 14, 2024, 4:30 AM

#

You did set them, but then set them to null

timid anchor Nov 14, 2024, 4:31 AM

#

warm tapir Nov 14, 2024, 4:31 AM

#

vapid whale Nov 14, 2024, 4:31 AM

#

Remove:
anim = PlayerSprite col = PlayerCollider

warm tapir Nov 14, 2024, 4:32 AM

#

okay lol

timid anchor Nov 14, 2024, 4:32 AM

#

vapid whale Remove: `anim = PlayerSprite col = PlayerCollider`

This is in the third party code

#

The mega script I was talking about

#

The sample project works

timid anchor Nov 14, 2024, 4:33 AM

#

warm tapir okay lol

I think you shouldn't be editing that code

#

Something else is going on

warm tapir Nov 14, 2024, 4:34 AM

#

yeah no i dont see a reason to make changes like that

#

especially when it works just fine in the sample

vapid whale Nov 14, 2024, 4:34 AM

#

But the issue is that these nodes are null, right?

warm tapir Nov 14, 2024, 4:34 AM

#

i tried it out of curiousity though

#

lead to the same error

timid anchor Nov 14, 2024, 4:35 AM

#

The exports take in those two nodes
The script then assigns them to those variables (I guess as a protection from changing the export at run time)

#

Do you have any autoloads set up @warm tapir ?

warm tapir Nov 14, 2024, 4:35 AM

#

It also called anim and col alot later in the codebase

#

Nope

#

you mean this right?

timid anchor Nov 14, 2024, 4:36 AM

#

Right

vapid whale Nov 14, 2024, 4:36 AM

#

timid anchor - The exports take in those two nodes - The script then assigns them to those va...

Oh, you're right. My bad.

timid anchor Nov 14, 2024, 4:37 AM

#

Um, on that UltimatePlatformerController script, right click, View owners

warm tapir Nov 14, 2024, 4:37 AM

#

wait right click where i dont see it lol

timid anchor Nov 14, 2024, 4:38 AM

#

warm tapir Nov 14, 2024, 4:39 AM

#

timid anchor Nov 14, 2024, 4:42 AM

#

Hmm yeah idk

#

At this point I would start removing and adding the nodes back in

warm tapir Nov 14, 2024, 4:42 AM

#

honestly

timid anchor Nov 14, 2024, 4:43 AM

#

maybe zip it up and send it too

warm tapir Nov 14, 2024, 4:44 AM

#

I might just cannibalize the sample project and see if I have better luck with it xD

#

It's not like I've done very much

#

I've only spent a day or two on this

#

well

timid anchor Nov 14, 2024, 4:44 AM

#

It's up to you, I feel like it would either just work on my machine, or I would find some strange unconnected thing

warm tapir Nov 14, 2024, 4:45 AM

#

a day or two before finding this script

#

what exactly would I be archiving?

timid anchor Nov 14, 2024, 4:45 AM

#

Just the whole folder and all files except the .godot folder

warm tapir Nov 14, 2024, 4:51 AM

#

I'll send it just for the hell of it anyways.

timid anchor Nov 14, 2024, 4:51 AM

#

sure

warm tapir Nov 14, 2024, 4:53 AM

#

uhm do I just post the link here or what

timid anchor Nov 14, 2024, 4:53 AM

#

sure

mmx6-rb.7z

shared with file.io - super simple file sharing

timid anchor Nov 14, 2024, 4:55 AM

#

got enough addons there? 😅

warm tapir Nov 14, 2024, 4:55 AM

#

LMFAO

#

I was just clicking download on a bunch that looked interesting only later realizing that they overwrite the same files and stuff

#

And now I see that you should probably only download ones you'll actually use.

timid anchor Nov 14, 2024, 4:57 AM

#

I think you gave me everything except for the scenes and script that I need lol

warm tapir Nov 14, 2024, 4:57 AM

#

wait what

#

https://file.io/IcXfRMYk9OgB

oops.7z

shared with file.io - super simple file sharing

#

i realized I forgor to move the folders lol

timid anchor Nov 14, 2024, 5:03 AM

#

If you restart the project, do you get any script errors?

warm tapir Nov 14, 2024, 5:04 AM

#

oh yup

#

Failed to load parse error

timid anchor Nov 14, 2024, 5:05 AM

#

So there were multiple versions of this same script

#

Probably not a good idea to throw in hundreds of addons to start with

#

the UltimatePlatformerController.gd was in there twice

warm tapir Nov 14, 2024, 5:06 AM

#

hahahaha

timid anchor Nov 14, 2024, 5:06 AM

#

and one of the player.gd scripts seemed to also be a replica of UltimatePlatformerController.gd

warm tapir Nov 14, 2024, 5:06 AM

#

it throws a fit cause of that I assume?

#

I was meaning to delete those

timid anchor Nov 14, 2024, 5:07 AM

#

After deleting all of those, putting back in that previously deleted code under _ready(): it worked properly

warm tapir Nov 14, 2024, 5:07 AM

#

oh

#

well shit

#

LMFAO

timid anchor Nov 14, 2024, 5:07 AM

#

I don't know how long it would have taken to arrive at this conclusion had I not seen the project 😄

warm tapir Nov 14, 2024, 5:08 AM

#

Potentially days LMAO

#

Okay good to know it's something dumb and mundane like that

#

I'll try it after I come back from the store lol

warm tapir Nov 14, 2024, 7:29 AM

#

That did indeed fix it
