"This superfield was not present in UT v436"

[Barbie]

I continued the work on an old map and fixed the code of a "FrozenSkaarjWorrior", when I got the following message on saving the map:

Function MyLevel.CrevsLvlDecos.PostBeginPlay has superfield Engine.Decoration.PostBeginPlay. This superfield was not present in UT v436, so this package will not work on UT v436 clients or servers. Do you want to use Engine.Actor.PostBeginPlay as the superfield to fix this compatibility problem?

The code of MyLevel.CrevsLvlDecos:

Code: Select all

class CrevsLvlDecos extends Decoration abstract;
...
function PostBeginPlay() {

	if (bActivateFadeOut)
	{
		If (Visible_RadiusBasic == 0) Visible_RadiusBasic = 768;
		If (Visible_HeightBasic == 0) Visible_HeightBasic = 768;
		If (Visible_RadiusExtra == 0) Visible_RadiusExtra = 256;
		If (Visible_HeightExtra == 0) Visible_HeightExtra = 256;
		self.VisibilityRadius = Visible_RadiusBasic+rand(Visible_RadiusExtra);
 		self.VisibilityHeight = Visible_HeightBasic+rand(Visible_HeightExtra);
	}
}

What to do?

I mean, CrevsLvlDecos.PostBeginPlay() does not even call Super.PostBeginPlay()? Why the warning then?

[Buggie]

Because any use of function, regardless of call Super or not, make link to parent function. That how compiler and engine works.

What to do?

Answer "yes" to compatibility question. And there will be no problem with old clients. New clients will work fine as well.
