The picker is used in the special node dialog and also in monster abilities.
Some changes were made to the game as well:
* If the rotatable wall is used for a field missile or touch ability, there's no longer an option for the designer to pick an orientation. Instead, it behaves like the rotatable wall in a radiate field ability, selecting an orientation based on the creature's facing direction.
* The magic values sent to place_spell_pattern for direct damage were rearranged to match the order of the eDamageType enum. This should have no effect, since the core place_spell_pattern function is only called by the various wrapper overloads. It also simplifies the code quite a bit.
* The Protective Circle spell pattern is now exposed to the place patten special nodes. It can be used as just a radius 4 circle, but the effect of different layers of fields can also be obtained by specifying a field type or damage type of -1.
There is also a change to the dialog engine:
* Calling setText() also implicitly calls recalcRect()
The limit of 3 saved item rectangles has been removed - you can now add as many as you want.
However, the 1 per town limit is now strictly enforced.
The saved item rectangle is now shown with a cyan border when editing town.
These are the rules:
- If the active PC gets an empty shop, iterate from the first to last PC until finding someone who can see a shop item
- If none can shop, show the 'no item' response
- When the active PC buys something, if this clears out the shop, iterate from the first to last PC until finding someone who can see a shop item
- if none can see an item, stay on the empty shop of the PC that was active when the last item was bought.
- When shopping ends, if the shop interface was the last thing to change the player's active PC, it puts it back how it was.
