Collecting Swap Actors in a Widget
Connection using a Blueprint Interface (UI3)
BPI_UI3_Interaction
This interface is part of the UI3 and will be available when the UI3 is present in the project. It needs to be added in the Class Settings of the BP_Doors_Swap_Actor.
Connecting Swap Actor and Door
MyProject / Content / DoorsBPV2 / Blueprints / BP_Doors_SwapActor
Place the Swap Actor next to the door and then use the eyedropper to connect one or more door blueprint actors.
Both Swap Actor and Door need to be in the same level.
Set up Swap Actor
Style Variations
- Click the relevant (+) icon next to the style's name for each variation choice.
- Then select the choice from the dropdown list.
- Give the style a Tag name.
The Tag and the variation ID will be sent from the widget. Every option with the same tag name will change. All options will change at once if they have the same tag name or individually if they have unique names.
Material Variations
- Click the (+) icon to add a Material Variation
- Add one or more Parts that should change to the new material
- Click the (+) icon next to Variations for each material ID that should be changed
- Enter the material ID number
- Add the Materials per Choice ID.
- Add a Tag name as described for style changes.
Controller Connection
The Doors and the Player Controller are connected through the BPI_Doors_Interaction blueprint interface.
Interaction
The controller calls the Interact function in the doors to manually open them with the [R] key.
Style Changes
Only used in versions before 2026-05.
The keys [1] to [6] will call the Set Variation function to change the style or materials. This is a simple example how to use the blueprint interface.
