How to load scripts within a script

[Codified-Vexing]

I need an hint as to how to load scripts. self.prog = ResourceLoader.load(str(path)).new() Throws a long error message.

I've successfully loaded a py script into a GD script with constructors too but couldn't call the function in the loaded class.

See my post.

As I see you're trying to do the opposite 🙂

Hi @Codified-Vexing,

Can you provide more information about your issue ? like the error message and parameters, and ideally a minimal code to reproduce the issue ?

[Codified-Vexing]

In a file named "PeriphPanel.gd" I have the following:

func _ready():
    var foobar = load("res://DEVICES/generic_device.tscn").instance()
    $devList.add_child(foobar)
    foobar.set_prog("res://DEVICES/CUSTOM/Addition.py")
    foobar.prog.handler("It Works!")

Where it throws the error: Invalid call. Nonexistent function 'set_prog' in base 'VBoxContainer (generic_device.py)'. The "generic_device" script is as such:

@exposed(tool=True)
class generic_device(VBoxContainer):

    prog = export(PluginScript)

    def set_prog(self, path):
        self.prog = ResourceLoader.load(str(path)).new()

The "Addition.py" has:

@exposed
class Addition(Node):

    def handler(self, this):
        print(this)

This is what appears in the Editor's Output Panel:

if I replace set_prog() to just print path instead of trying to load the file, this appears:

@Codified-Vexing try using the class this way:

func _ready():
    var foobar = load("res://DEVICES/generic_device.tscn").instance()
    $devList.add_child(foobar)
    foobar.call("set_prog", "res://DEVICES/CUSTOM/Addition.py")
    foobar.prog.handler("It Works!")
