Unity Script Reference:

static function Vector4Field(label: string, value: Vector4, params options: GUILayoutOption[]): Vector4;

static Vector4 Vector4Field(string label, Vector4 value, params GUILayoutOption[] options);

static def Vector4Field(label as string, value as Vector4, *options as GUILayoutOption[]) as Vector4

Parameters

label	Label to display above the field.
value	The value to edit.
options	An optional list of layout options that specify extra layouting properties. Any values passed in here will override settings defined by the `style`. See Also: GUILayout.Width, GUILayout.Height, GUILayout.MinWidth, GUILayout.MaxWidth, GUILayout.MinHeight, GUILayout.MaxHeight, GUILayout.ExpandWidth, GUILayout.ExpandHeight.

Returns
Vector4 The value entered by the user.

Description

Make an X, Y, Z & W field for entering a Vector4.

Modify X,Y,Z and W values directly of a GameObject.

	// Simple script that lets you modify the X,Y,Z and W 
	// Quaternion values of the selected GameObject
