Draw default property types in custom PropertyDrawer

[Joseph-Ferano]

If I made a custom attribute that I wish would be applied to all properties, is there a way I can make it draw the respective EditorGUI field?

Right now, I would have to go through each property like so;

if (property.propertyType == SerializedPropertyType.Float)
            EditorGUI.Slider (position, property, range.min, range.max, label);
        else if (property.propertyType == SerializedPropertyType.Integer)
            EditorGUI.IntSlider (position, property, range.min, range.max, label);
        else
            EditorGUI.LabelField (position, label.text, "Use Range with float or int.");

That would be pretty inconvenient to have to write all that. Any way around this?

This is an old thread, but here is the solution.

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        EditorGUI.PropertyField(position, property, label, true);
    }

    public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
    {
        return EditorGUI.GetPropertyHeight(property);
    }

If you want to expand it’s functionality with eg. a button:

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        EditorGUI.PropertyField(position, property, label, true);
        if (property.isExpanded)
        {
            if (GUI.Button(new Rect(position.xMin + 30f, position.yMax - 20f, position.width - 30f, 20f), "button"))
            {
                // do things
            }
        }
    }

    public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
    {
        if (property.isExpanded)
            return EditorGUI.GetPropertyHeight(property) + 20f;
        return EditorGUI.GetPropertyHeight(property);
    }

foreach (SerializedProperty a in property)
{
position.y += 20;
EditorGUI.PropertyField(position, a, new GUIContent(a.name));
}
