Participants interact with items: 5pts

[skleinfeldt]

User story:

As a participant, if I occupy the same square as any object, I can see information about the object, and (for now) the transitions which would occur when clicking the action button.

Task Breakdown

• Player cannot occupy the same square as an Item where crossable is false
• Player can occupy the same square as an Item where crossable is true
• When sharing a square with a crossable Item, the ego player can see:
  • Properties of the Item
  • Available transitions on the Item

"APIs"

• Get Item at position
• Iterate over items
• Remove item from collection
• Is Item at position crossable?
• Get public-facing properties of an Item
• Get public-facing transitions for an Item
• Display properties and transitions to ego player

I have a question on PR #253 related to non-"crossable" items. Some of these non-crossable items have available transitions. In such cases, is the transition availabile when adjacent to the square with the item? If so, how do we disambiguate the target when there are multiple adjacent items? For now it might be best to avoid allowing transitions on impassable items, since if a transition requires being on the same square then it could never be executed, and if it doesn't, it could add significant complexity.

@alecpm Good point - I agree, I think solely defining transitions on crossable items would be simpler

OK, so in the demo/default config we'll make the Gooseberry Bush crossable, and maybe keep the Empty Gooseberry Bush non-crossable for fun.

@jessesnyder Here are the mock-ups that we discussed during the meeting! To recap: The first image shows how transitions might appear to participants when they are (a) visible (b) hidden or (c) visible if previously seen. In the second image, the object in the participant's hand is highlighted to indicate that it's edible.

@alecpm Sounds good!
