Syntax
[CustomPropertyDrawer(typeof(MonoTextAreaAttribute))]
public sealed class MonoTextAreaDrawer : PropertyDrawer
Remarks

Renders a string serialized property as a scrollable, multi-line text area that uses the Scylla default monospace font (ScyllaMono) loaded via LoadDefaultMono(). This is useful for fields that contain structured text, code snippets, or any content where character alignment matters.

The text area grows vertically based on the actual number of newlines in the current value, clamped between MinLines and MaxLines. A single-line label using the standard property label is drawn above the text area.

The monospace font is loaded once and cached statically. If the font cannot be found, the drawer falls back to the default UnityEditor.EditorStyles.textArea font without raising an error.

Applying this attribute to a non-string field renders an error label instead of a text area.
