I've seen this asked somewhere but it was never really discussed.
I would like to be able to have 3 houses on the overworld that warp like the 3 stair warp, each going to a different location.
Any ideas as how I may succeed in doing this?
3 houses on one screen
Put pit warps for all 3 doors. Tile warp to a black screen, set that as 3-stair warp. On the black screen all tiles (or just those under the pits) must be combo type stairs. One of the doors has to be in the central 2 columns of the screen, one to the left one to the right as 3-stair warp works by screen position. (Or set the doors as stair combo types and have the screen with the doors as 3-stair warp)
Then quest -> misc data -> warp rings. That's a technical name for 3-stair warps. There you set the targets for your individual warps. The 2.10test quest I believe uses a 3-stair warp somewhere so you can look at that as an example of setting it up.
