Unity Editor : How to resize and space value field of an inspector property field? - unity3d

Question

I am trying to implement my first unity editor code to make a custom array property drawer with indented named entries and indented and dynamicaly resized value fields.
I am using the following simple git solution as base for my code, which allows to set the labels of an array in the inspector : HERE
replacing the example shown in the gitHub solution, I am working with this enum as my array element name container:
[System.Serializable]
public enum HealthNames
{
General,
Head,
Body,
RightArm,
LeftArm,
Rightleg,
leftLeg,
}
and sets it up on a array in a monobehaviour class :
[ LabeledArray( typeof( HealthNames ) ) ]
public int[] m_aHealth = new int[ Enum.GetNames( typeof( HealthNames ) ).Length ];
I have added EditorGUI.indentLevel++; and EditorGUI.indentLevel--; at the start and end of the try statement to indent the label of the array elements, making them stand out from the size property.
Going from there, I have searched ways to add an indent on the elements' value fields or remove it from the size property's value field. but have found no answer using EditorGUI
I also looked to be able to resize all value fields dynamicaly, but there again, no answer came using EditorGUI only. there is no way to use EditorStyle.AnyField.WordWrap = true; on a propertyfield. Passing the PropertyField to an IntField, using a EditorStyles.NumberField and setting having its wrodwrapping set to true beforehand has no effect.
I also have found a small number of EditorGUILayout from a few years ago, but which do not work since the solution is built from the ground with EditorGUI
In hope of your enlightment on the matter

Answer 1

If I understand you correctly you want the labels and the value fields indented.
I think it could be done like e.g.
private const int INDENT = 15;
public override void OnGUI(Rect rect, SerializedProperty property, GUIContent label)
{
EditorGUI.BeginProperty(rect, label, property);
var fieldsRect = new Rect(rect.x + INDENT, rect.y, rect.width - INDENT, rect.height);
try
{
var path = property.propertyPath;
int pos = int.Parse(path.Split('[').LastOrDefault().TrimEnd(']'));
EditorGUI.PropertyField(fieldRect, property, new GUIContent(ObjectNames.NicifyVariableName(((LabeledArrayAttribute)attribute).names[pos])), true);
}
catch
{
EditorGUI.PropertyField(fieldRect, property, label, true);
}
EditorGUI.EndProperty();
}
