Question about DrawDefaultInspector()

Hello,

I have seen someone in a tutorial use:

Code (CSharp):

1. if (DrawDefaultInspector())
2. {
3.     DoSomething();
4. }

He said that when a value in the editor is changed DoSomething() will be called. I can not find much about using DrawDefaultInspector() for this purpose.
I also can not manage to make it work for me. I've made a custom editor to be able to increment/decrement values with check boxes and I wanted to use

if (DrawDefaultInspector())

to do the incrementation/decrementation when a box is checked.

When I check/uncheck any boxes nothing happens. Does DrawDefaultInspector() return true only when a variable serialized by the default Inspector is edited? Is so what would be an alternative for the custom editor? At the moment I achieve this by checking each bool at a time if it's true, which doesn't really seem right for me.

Thanks for your time = )

 

For this use, I don't think you want to care about the return value from DrawDefaultInspector().

I think you would only care about that bool if you were going to take action based on a change to those properties via the default inspector.

If I understand your use, your new up/down boxes are the ones taking the action, right?

If you call DrawDefaultInspector it will draw whatever it would normally draw there. This might be nothing.

 

Code (CSharp):

1.         EditorGUI.BeginChangeCheck();
2.  
3.         //Your field goes here
4.  
5.         if (EditorGUI.EndChangeCheck())
6.         {
7.             //The value of your field has changed
8.         }

 

When one of the boxes is checked I set the bool to false and add/subtract 1 from a value. These bools do not have any other uses than to be used in the editor. They act like buttons. (I know that I could use normal EditorGUI buttons for this too)

 

This works. Thanks!
Can someone tell me when and what the function

DrawDefaultInspector()

returns so that I won't have any confusion in the future?

 

I wasn't even aware that

DrawDefaultInspector()

returned a bool, and the docs say nothing about what determines if it returns true or false.

The purpose of the method is to, as its name states, just draw the default inspector of a script. Perhaps it returning a bool implies it can fail to draw the default inspector, and you would use the return value to draw a fallback inspector like this?

Code (CSharp):

1. if(!DrawDefaultInspector()) {
2.   //Draw a custom fallback inspector if the default inspector could not be drawn.
3. }

I've yet to see something like that occur, but that's my guess.

 

I've noticed the same thing. That's why I was confused about it's use. But I think your guess is right, it does make sense.

 

If you look into the source code, it returns true if the serialized value changes.
