SDT0403: Missing Enum Field Mapping Attribute

Property	Value
Rule ID	SDT0403
Title	Missing Enum Field Mapping Attribute
Category	Input
Severity	Error

Cause

An enum is decorated with [InputMapper], but one or more of its individual fields are missing their required specific mapping attribute.

Rule Description

When an enum is registered as an input mapper, the input system relies on reflection to bind each enum value to a specific physical input (like a button or axis). If a field is missing its mapping attribute, the input system will fail to bind it.

How to Fix Violations

Ensure every field inside the enum has the correct mapping attribute applied to it.

Violation:

[InputMapper]
public enum PlayerActions 
{
    [MappedButton]
    Jump,

    // Missing attribute!
    Crouch 
}

Fix:

[InputMapper]
public enum PlayerActions 
{
    [MappedButton]
    Jump,

    [MappedButton]
    Crouch 
}
