Universal Door Blueprint V1 - UE 4.25

Documentation for the First Version Universal Door Blueprint available on the Unreal Marketplace for Unreal 4.25 or higher

There is a very simple controller used to test the auto and manually opening doors. You can play the level to test the interactivity. Check the blueprint setup in the controller to see what you have to do in your character or controller. More further down.

Finally a couple of doors are setup to work with the ArchViz user interface. You can't trigger material changes directly but you can use them as children to be triggered by other actors (like the skirting boards). See further down how to add the nodes needed for material changes. It's very easy. - The controller here uses the keys 1,2,3 as placeholders.

Without ArchViz User Interface

If you want to add your own logic to swap materials then simply add an Event Dispatcher to your character or controller and call it when you want the doors to swap their material. Seen in the grey section of the image, the Dispatcher needs to have these two variables:

• TagOut - string the doors are listening to trigger the change.
• VariationID - Integer that tells the door to which material it should swap

The yellow area is already set up in the door blueprint but you need to replace the existing character with your character.

Connect to Player Character

In both cases you need to reconnect the player character.

• (1) from the [Get Player Character] node drag off [the Return Value] pin and select your character by typing the name.
• (2) from the [As ... Character] node get the event you created or find [Swap Material by Code]
• (3) from the Event node create a custom event and name it.
• (4) from the custom event connect the output nodes like seen in the image.

The yellow part is what is currently set up in the door blueprint.

(2) Replace the original node with your own controller node.

(3) From your 'As Player Controller...' node drag off a new connection and choose 'Bind event to ... (your dispatcher)'. Then replace the existing dispatcher with your dispatcher.

(4) Connect the red node to the 'OpenDoor' node. Now you should be able to open the door manually.

NOTE: It won't let you connect your dispatcher to the 2nd dispatcher past the branch node on the other side. This is ok as you most likely won't use the colour scheme feature available in the SDot_Character and UI. Otherwise replace the existing 2nd dispatcher with your dispatcher as well.
