Unit AI - Discrete Behaviours

[snayff]

Suggested Feature

Give Units a behaviour to dictate how they act.

Requirements

• Only 1 specific behaviour can be active at a time
• Seek behaviour:
  • Actors in Unit move towards a fixed region/point, or to within range of the fixed point
• Flee behaviour:
  • Actors in Unit move away from a fixed point
• Pursue behaviour:
  • Actors in Unit predict the future location of an enemy Unit and move to intercept it
• Unit can be given a location to move to (code only for now, gui later) (this is preamble for when the player can direct Units.)
  • the new location overrides any current target
  • after reaching the new location or certain time length has passed, revert to previous target
