GD0003: Found multiple classes with the same name in the same script file

Rule ID	GD0003
Category	Usage
Fix is breaking or non-breaking	Non-breaking
Enabled by default	Yes

Cause

A script file contains multiple types that derives from GodotObject with a name that matches the script file. Only one type in the script file should match the file name.

Rule description

Redot requires scripts to have a unique path so every type must be defined on its own file and the type name must match the file name.

public partial class MyNode : Node { }

namespace DifferentNamespace
{
    // Invalid because there's already a type with the name MyNode in this file.
    public partial class MyNode : Node { }
}

// Invalid because there's already a type with the name MyNode in this file.
public partial class MyNode<T> : Node { }

How to fix violations

To fix a violation of this rule, move each type declaration to a different file.

When to suppress warnings

Do not suppress a warning from this rule. Types that derive from GodotObject must have a unique path otherwise the engine can't load the script by path, resulting in unexpected runtime errors.
