Setup Wall Asset

In this example, we'll use a simple cube as a wall. Create a new cube mesh from the create menu

Parent this cube under the Wall game object.

We need the wall to be 4 units wide and 5 units tall (to cleanly cover up the gap we created in our modules previously)

Select the cube mesh and set the scale to (4, 5, 1)

The wall should be moved appropriately so that:

• The red line is at the bottom-center of the wall

• The wall should be behind the red line's origin point

Move the wall up and a bit back by setting the location to (0, 2.5, -0.5)

Setup Door Asset

There's a simple Door prefab that comes bundled with the samples. We'll use that here, however, feel free to use your own door prefabs

Navigate to Assets\CodeRespawn\DungeonArchitect_Samples\DemoBuilder_GridFlow\Art\Prefab and drop in the DoorLarge prefab under the Door game object

Go ahead and hide the Wall game object. Dungeon Architect will take care of making it visible where needed

The rules for aligning the door with the red line are a bit different

You should move the door asset so that:

• The red line is at the bottom-center of the door

• The origin point of the red line should be at the center of the door

Our door prefab is already of the correct size (5 units tall and 4 units wide) and the pivot is in the right position. So reset the transform of the DoorLarge game object

You'd want your door asset to be twice as thick as the walls. This is because when two adjacent modules are stitched together, we have two walls from each modules and a door that is twice as thick as the walls will cleanly fill up the gap

Setup One-way Door Asset

Some doors will be promoted to one-way doors. This is done so that the player doesn't bypass a locked door and enter through another nearby door. You'll need to provide a door prefab that opens only from one way

Right now, the snap connection is setup to support a Door and a Wall. We are going to add support for a one-way door.

1. Create a new game object and name it OneWayDoor. This should stay alongside the Door and the Wall prefabs

   

   

2. Select the DoorOneWay game object and reset the transform

   

   

3. Let the SnapConnection know that this game object represents a one-way door. Select the root SnapConnection game object and inspect the properties

   

   

   We'll assign our newly created DoorOneWay game object here

   

We can now place our one-way door assets under this. Navigate to Assets\CodeRespawn\DungeonArchitect_Samples\DemoBuilder_GridFlow\Art\Prefab and drop in DoorLargeOneWay prefab as shown below

The alignment rule of a one-way door is similar to a door. The direction in which we are allowed to go through the door should follow the red line outwards

Reset the transform of the asset and rotate it along Y by 180 degrees since it is facing the wrong way

Hide the Door and DoorOneWay game objects

Our snap connection is now complete and we are ready to place them in our snap modules

Exit out of the snap connection prefab and return to the scene by clicking the Scene button on the viewport
