place item on map instead of in code

[denispir]

Hello all,

[I ask this question here because there does not seem to be any forum dedicated to maps, else tell me where it should belong and/or move the thread.]

Is it possible to have an item on the map directly (if only by modifying its text file) instead of placing it in WML code? I think at having it be an overlay as for mixed terrains (with the '^' sign in text).

Thank you,
Diniz

Usually not, though it is possible to use WML to create new terrain types that look like items.

Take a look at the brazier "embellishment' terrains (^Eb, ^Ebn) as examples, I think they do what you want. You'll still need to define what the terrain code does, but then you can add it as an overlay with the "^" on a map.

Do you mean something as externally referenced item so you only need to call in the scenario file?

Since that is possible. Something like this in the macros:

Code: Select all

And then in the scenario file you place it with {RING_DEFENSE 33 70}

Do you mean, although there's some WML involved, the location is chosen in the map editor instead of putting the coordinates in to the WML?

This works in 1.14, in the map editor the labels are placed with the "player start" tool (click "Add", and then type a name that doesn't start with a number). Units then can be placed using "location_id=" instead of "x,y=".

The WML on the back of picture above is:

Code: Select all

  # The dwarvish treasury is accessible via a guarded rope-bridge, which will be cut
  # if a non-flying unit moves on to it.
  #
  # For now let's just cut it when a unit gets close (when it's on the hex
  # before the bridge).  If the trap gets more complex, the player's unit
  # should stop there anyway, and warn that there's a dwarf waiting to cut the
  # bridge.
  [event]
    name=enter hex
    # It will only modify terrain for non-flying heroes, and it makes sense to
    # have the dwarf laugh again every time someone steps on this hex.
