I’ve been following UmaiPixel tutorials (on part 5) and for some reason, it gives me this error. My Godot version is 3.0, but his Godot version is 3.0.6. Is that why?

This = const POWERBEAM = preload(“res://”)
this = const POWERBEAM = preload(“res://Power_Beam.tscn”)

gd and tscn

The problem is likely as answered.

Aside from that, I would advise you update your Godot version later, Godot 3.0 was released 4 years ago, now the engine is version 3.4.3 and had tons of improvements.

Well, I would have followed with the current version I have (3.4.2) but the tutorial pretty much called for Godot 3, as there were errors if you used Godot 3.1 so I had to download an older version. (PS nearly done with the tutorial)

umm I think its doing that because u preload a .gd not the .tscn

instead of this

const POWERBEAM = preload(“res://”)

use this

const POWERBEAM = preload(“res://Power_Beam.tscn”)

the .gd is a script while the .tscn is the scene
