Dungeon room placement

[hazy gull]

Hi, I'm generating dungeon rooms which connect at exits which are empties where doors would be, but I can't figure out the math to place them correctly. Here's the current functionality and a screenshot. This is for a game jam as well so it's slightly urgent.

foreach(DungeonRoomExit exit in exit_nodes)
{
    if (!exit.occupied)
    {
        int rand = Mathf.FloorToInt(Random.Range(0, room_prefabs.Count));
        DungeonNode new_room = Instantiate(room_prefabs[rand]);

        int rand2 = Mathf.FloorToInt(Random.Range(0, new_room.exit_nodes.Length));



        // find the new rotation of the new room
        float new_rot = new_room.exit_nodes[rand2].transform.rotation.eulerAngles.y + new_room.exit_nodes[rand2].transform.rotation.eulerAngles.y;

        new_room.transform.rotation = Quaternion.Euler(new Vector3(0, new_rot, 0));
        new_room.transform.position = exit.transform.position - new_room.exit_nodes[rand2].transform.localPosition;
                
        // draw connection
        Debug.DrawLine(exit.transform.position, new_room.exit_nodes[rand2].transform.position, Color.red, 60f);

        new_room.exit_nodes[rand2].occupied = true;
        exit.occupied = true;
        return;
    }
}

Ideally the red line between exits shouldn't be visible because they would overlap

you want them to overlap?

Yeah, let me take a better screenshot

In this case the two connections are across the second room

My goal is to have it rotated 180 from that position, but no matter what I try it comes out wonky

Here's the code that placed that room

foreach(DungeonRoomExit exit in exit_nodes)
{
    if (!exit.occupied)
    {
        int rand = Mathf.FloorToInt(Random.Range(0, room_prefabs.Count));
        DungeonNode new_room = Instantiate(room_prefabs[rand]);

        int rand2 = Mathf.FloorToInt(Random.Range(0, new_room.exit_nodes.Length));



        // find the new rotation of the new room
        float new_rot = exit.transform.localRotation.y + new_room.exit_nodes[rand2].transform.localEulerAngles.y;

        //new_room.transform.forward = new_room.exit_nodes[rand2].transform.forward;
        new_room.transform.rotation = Quaternion.Euler(new Vector3(0, new_rot, 0));
        new_room.transform.position = exit.transform.position + new_room.exit_nodes[rand2].transform.position;
                
        // draw connection
        Debug.DrawLine(exit.transform.position, new_room.exit_nodes[rand2].transform.position, Color.red, 60f);

        new_room.exit_nodes[rand2].occupied = true;
        exit.occupied = true;
        return;
    }
}

Thanks for your time, I really appreciate it

define wonky

The two connections never line up and are always at the wrong angle. The goal is for the empties at the openings to be completely flush

In this case, they're 180 from each other

And adding 180 or many of the things I've tried haven't helped and have just left me stumped

It feels like the euler angle should be the angle of the first opening plus the angle of the target opening, but that didn't work

we're talking about the room's rotation right

[hazy gull]

Yep

sorry im a little slow on responses rn im tryna do some stuff with my editor

[hazy gull]

You're good, I'm just fiddling with it trying to make it work

[hazy gull]

It's working a tiny bit

One sec

foreach(DungeonRoomExit exit in exit_nodes)
{
    if (!exit.occupied)
    {
        int rand = Mathf.FloorToInt(Random.Range(0, room_prefabs.Count));
        DungeonNode new_room = Instantiate(room_prefabs[rand]);
        int rand2 = Mathf.FloorToInt(Random.Range(0, new_room.exit_nodes.Length));

                
        Transform con_1 = exit.transform;
        Transform con_2 = new_room.exit_nodes[rand2].transform;

        float angle = (180 + con_1.eulerAngles.y) - con_2.localEulerAngles.y;

        new_room.transform.position = exit.transform.position;
        new_room.transform.Rotate(new Vector3(0,angle,0));
        new_room.transform.position += con_1.localPosition;

        // draw connection
        Debug.DrawLine(exit.transform.position + Vector3.up, new_room.exit_nodes[rand2].transform.position + Vector3.up, Color.red, 60f);

        new_room.exit_nodes[rand2].occupied = true;
        exit.occupied = true;
        return;
    }
}

It works until this room here to the right

well the difference between that one and the rest is that the empty wall side is on the left
