Legacy:Variable Panning Textures

From Unreal Wiki, The Unreal Engine Documentation Site

Ordinary scrolling textures are set with the panning Surface Flags (UT), and the speed is set over each entire zone in the ZoneInfo actors. Here's a way to work around this restriction, using the Screen component.

Ingredients

You will need the following elements:

ScriptedTexture

Use one of the ScriptedTexture (UT)s from the ScriptedScreen texture package. Apply this to the surface you want to scroll. Note that you can use this texture on as many surfaces as you wish, they'll all display the same thing.

ScreenSlidePage

Select the text below, copy, and paste into UnrealEd to get the settings.

<uscript> Begin Map Begin Actor Class=ScreenSlidePage Name=ScreenSlidePage0

   Text=""
   AlignHorz=SlideAlignHorz_Left
   AlignVert=SlideAlignVert_Top
   ClientWidth=256
   ClientHeight=256
   ClientPaddingTop=0
   ClientPaddingLeft=0
   ClientPaddingRight=0
   ClientPaddingBottom=0
   ScrollHorz=SlideScroll_None
   ScrollVert=SlideScroll_None
   EffectEntry=SlideEffect_SlideBottom
   EffectEntrySpeed=128.000000
   EffectExitSpeed=0.000000
   SlideNext=ScreenSlidePage'MyLevel.ScreenSlidePage0'
   Name=ScreenSlidePage0

End Actor End Map </uscript>

Set the following properties:

Category Property Value
ScreenSlide Background Desired texture.
ScreenSlide Palette Same as Background (to make the slide use the texture's actual palette rather than the default one).
ScreenSlide EffectEntrySpeed Desired speed in pixels per second.

Screen

Create a Screen actor and set the following properties:

Category Property Value
ClientScriptedTexture ScriptedTexture Set to the ScriptedTexture you selected in the first step.
Screen SlideCurrent Set to the name of the [[Screen ScreenSlidePage]] actor. Note: You can't do this with the Use button, you need to find out its Object -> Name property, remember it and type it into the Screen's property.
