Affected Unit

Entity affected_unit

An Entity that reacts to actions or gives feedback but stores no value of its own. It is operated, triggered or changed and clearly signals that.

Design question – What should your game react to visibly? Which elements give the agents feedback?

Reference example – Operation: if the tweezers touch the edge, it buzzes and the nose lights up. Pinball: the bumpers light up and kick the ball back. Angry Birds: wooden beams and glass panes break on impact.

Dimension profile

• mutability – state_change (switches states in reaction)
• persistence – persistent (type-open)
• control – uncontrolled (defining)
• visibility – open (must react perceptibly)
• ownership – variable (usually ownerless)
• mobility – fixed (usually fixed)
• interactivity – action_trigger (defining (trigger/passive))
• value – none (defining (no value of its own))

Compatible with

• Value Container (ENT-06) – Both uncontrolled; distinguished by value-bearing.
• Static Unit (ENT-08) – Both uncontrolled/fixed; distinguished by reaction vs. immutability.
