Connections

A Snap Connection tells DA how to stitch the room modules together. They are usually the Door Entry / Exits.

The connection also contains references to two assets, a references to a Door prefab and a reference to a Wall prefab.

If DA stitches another module through that connection point, it would place the specified Door prefab in that place. Otherwise it would fill up the gap with the specified Wall prefab

Design a new Connection prefab by creating an emtpy Game Object

Reset the transform of the newly created emtpy Game Object and rename it

Add a SnapConnection script to it

This script takes references to the above two mentioned prefab references, one for door and another for wall

Drop your Door and Wall prefabs under the Connection prefab

Align the door and wall prefabs so the Red line is perpendicular to it

Now set these child door / wall prefab references on the SnapConnection script

Your connection is ready. Turn this into a prefab so we can reuse this in our modules

Drag and drop the connection prefab on your previously generated modules. Make sure the red line points outwards from the opening

Make sure the red line is pointing outwards and is on the edge of the module bounds

Repeat by drag-dropping on all the door openings. Do this for all the other modules as well (like the corridor module)

Save/Update your module prefab
