How do map levels work? I wrote names but it doesn't show on the map...

And how can I disable the frame map for the intro and then reactive it again? The set variable for this purpose doesn't work.

And when using maps, how can I move the player to a random room where the map has been created yet? It gives me an error of coordinates. Or is it possible that the whole map be created since the beggining?

Anybody?

From bottom to top:

I actually just answered this one recently. Check out this thread:

To hide it:

JS.ShowGrid(0)

To show it again:

JS.ShowGrid(game.mapsize)

I don't know what this means. Can you describe more what you have done so far? (That will give me a start to look at it.)

Thank you Jay! About the last question I just filled the map level option in a room:

<attr name="grid_label">Garden</attr>

But that name doesn't show on the map. My font is white with black background.

There's a bug in the room draw code. You can work around it by adding the following function to your game file:

  <function name="Grid_DrawRoom" parameters="room, redraw, playerobject">
    <![CDATA[
    if (room.grid_render) {
      if (redraw or not Grid_GetRoomBooleanForPlayer(playerobject, room, "grid_isdrawn")) {
      
        if (room.parent <> null) {
          Grid_DrawRoom (room.parent, redraw, playerobject)
        }
      
        JS.Grid_DrawBox(Grid_GetGridCoordinateForPlayer(game.pov, room, "x"), Grid_GetGridCoordinateForPlayer(game.pov, room, "y"), Grid_GetGridCoordinateForPlayer(game.pov, room, "z"), room.grid_width, room.grid_length, room.grid_border, room.grid_borderwidth, room.grid_fill, room.grid_bordersides)
        
        if (LengthOf(room.grid_label) > 0) {
          label_x = Grid_GetGridCoordinateForPlayer(game.pov, room, "x") + room.grid_width/2.0
          label_y = (Grid_GetGridCoordinateForPlayer(game.pov, room, "y") + room.grid_length/2.0) - 0.5
          // Grid_DrawLabel(x, y, z, text)
          JS.Grid_DrawLabel(label_x, label_y, Grid_GetGridCoordinateForPlayer(game.pov, room, "z"), room.grid_label)
        }
      
        foreach (exit, AllExits()) {
          if (exit.grid_render and exit.parent = room and exit.grid_length > 0) {
            Grid_DrawLine (Grid_GetGridCoordinateForPlayer(game.pov, exit, "x"), Grid_GetGridCoordinateForPlayer(game.pov, exit, "y"), Grid_GetGridCoordinateForPlayer(game.pov, exit, "end_x"), Grid_GetGridCoordinateForPlayer(game.pov, exit, "end_y"), "black", 1)
          }
        }

        Grid_SetRoomBooleanForPlayer(playerobject, room, "grid_isdrawn", true)
      }
    }
    ]]>
  </function>

The code that calls JS.Grid_DrawLabel was passing "room.grid_z", which doesn't exist any more. I'll file a bug for this.

Edit: It turns out there already was a bug filed. I've updated it with my fix above.
