EditorGUI.indentLevel

Description

The indent level of the field labels.

Shows info of the selected object.

// Shows info of the selected transform
	
class EditorGUIIndent extends EditorWindow {
    
    @MenuItem("Examples/Indent usage")
    static function Init() {
        var window = GetWindow(EditorGUIIndent);
        window.position = Rect(0, 0, 100, 100);
        window.Show();
    }
    
    function OnGUI() {
        var obj = Selection.activeTransform;
        EditorGUILayout.LabelField("Name:", obj ? obj.name : "Select an Object");
        if(obj) {
            // Indent block more
            EditorGUI.indentLevel++;
            EditorGUILayout.LabelField("Position:", obj.position.ToString());
            EditorGUILayout.LabelField("Rotation:", obj.rotation.eulerAngles.ToString());
            // Indent inner block even more
            EditorGUI.indentLevel++;
            EditorGUILayout.LabelField("X:", obj.rotation.x.ToString());
            EditorGUILayout.LabelField("Y:", obj.rotation.y.ToString());
            EditorGUILayout.LabelField("Z:", obj.rotation.z.ToString());
            EditorGUILayout.LabelField("W:", obj.rotation.w.ToString());
            // End of inner block
            EditorGUI.indentLevel--;
            EditorGUILayout.LabelField("Scale:", obj.localScale.ToString());
            // End of block
            EditorGUI.indentLevel--;
        }
    }
}

To maximize future compatibility, do not make assumptions about what a specific indent level means, but instead just increase or decrease by one around blocks of controls that need to be more indented, as in the example above.
