The "Z" axis (traversing multiple floors in the same dungeon)

Hi!  New GM here, as well as new Roll20 user/supporter.  I'm wondering how people handle the issue in the title of this post.

I've placed a ladder in a dungeon that I envision leading down into another floor.  (Is there a way / what is the best way) to enable a player to be able to go down said ladder, in a way that changes their surroundings (map layer) and vision (light layer) and possibly the GM layer as well?

I realize that there is probably a way to do this that involves grouping items, but that seems unnecessarily time consuming in a tool as powerful as Roll20, and even that would require 'move to' commands across multiple layers.

Alternatively, is there a way to send one player to a page without sending any others?

Just wondering, thanks.

I would just make a section of the map that is over to the side somewhere that is the upper floor area. You can block it off with the Dynamic Lighting tool then drag the players to the new area when they go up the ladder. 

If you wish to move in individual player to a new map then you can do that while they are logged in by dragging their chat avatar to the map selection window and that will separate them from the party.  https://wiki.roll20.net/Page_Toolbar#Split_the_Party

Hi Brian,

I would split my map in two parts : one for the upper floor and one for the lower. Put a line on the layer for dynamic lighting to get two separates area.
And move the character to the floor when he climbs the ladder.

There are certainly other ways :)

Have a good day :)

edit : damn I wasn't quick enough :D

There is a wonderful way to do what you want. First place all your maps on one page and setup your dynamic lighting for each section, including the movement restriction. After that you go install two API scripts called "Collision Detection" and "Autoteleport and Chat based teleport". What this will let you do is define a specific token such as the "stairs" or "Ladder" to be a trigger (collision detection) to send the character's token to a specific location in another map. I would recommend posting in the API forums asking about what they could recommend for your needs.

Hey Brian,

There are several ways to do as you are asking. First of all, you can put the upper and lower floor maps on the same page and separate them via a dynamic lighting line as Pantoufle suggested.

The other (easy) way is to set up your maps on two different pages. Instead of dragging the player ribbon the to new map, drag the player's name from the bottom left onto the map in the page toolbar. To have the group party back up, drag the player's name onto the player ribbon. There's a clearer explanation on the wiki. 

Multiple Maps.
Break up the Party.
Deal with each separately in the Turn Sequence. :P


Also Ed S's option also allows you another thing: To fake the size of the 'dungeon' on the map.  Doing it with his modification means that the party aren't sure just how big each part of the dungeon is by the 'scroll bars' (if you have those sorts of meta-gaming Players).

The Collision Detection script doesn't really integrate with other scripts in any meaningful way, and it doesn't collide token-to-token, just token-to-path. That script was written prior to DL walls being able to restrict movement (although it can still be used to restrict movement across paths you can see through, since the script can inspect paths not on the GM layer).

Ah, I had thought it was rewritten to take advantage of the new aspects of DL so scratch that suggestion.
