ActionVariableCreateMenu

Popup menu that allows users to create new dynamic action variables from the Inspector. Presents a type selector and name input field, validates the input, and adds the variable to the owning ActionVariables container.

Definition

Namespace: Paragon.Core.ActionSystem.Editor Assembly: Paragon.Editor.dll

public class ActionVariableCreateMenu

Remarks

This menu is instantiated by ActionVariablesDrawer and opened when the user clicks the + button in the Variables header. It uses Odin's GenericSelector<Type> to present a list of supported variable types, then collects a variable name via a text field before committing the new variable.

The menu enforces two validation rules before enabling the "Add Variable" button:

1. Name validity — must match the pattern ^[a-zA-Z_][\w ]*(\.[a-zA-Z_][\w ]*)*$, must not be empty, and must not duplicate an existing variable name.

2. Type validity — must be one of the supported types listed below.

Validation Rules

Name Validation

private bool IsNameValid(string name)

Returns true when all of the following are satisfied:

• Name is not null or whitespace

• No existing variable in ActionVariables has the same name (HasVariable check)

• Name matches regex ^[a-zA-Z_][\w ]*(\.[a-zA-Z_][\w ]*)*$ — must start with a letter or underscore, may contain word characters and spaces, supports dot-separated segments

Type Validation

private bool IsTypeValid(Type type)

Returns true when the type is non-null and is one of the supported variable types.

Visual Behavior

The "Add Variable" button changes color to indicate state:

State	Button Color
No name or type selected	Gray (disabled)
Valid name and type	Green (enabled)
Invalid name or type conflict	Red (disabled)

Common Pitfalls

Duplicate variable names The menu rejects names that already exist in the ActionVariables container. The button turns red to indicate the conflict.

Name pattern restrictions Variable names must start with a letter or underscore. Names beginning with digits or containing special characters (other than spaces and dots) are rejected.
