◆ side_units_cost()

◆ unit_can_move()

display_context::can_move_result display_context::unit_can_move ( const unit & u ) const

Work out what u can do - this does not check which player's turn is currently active, the result is calculated assuming that the unit's owner is currently active.

◆ unit_orb_status()

orb_status display_context::unit_orb_status ( const unit & u ) const

Returns an enumurated summary of whether this unit can move and/or attack.

This does not check which player's turn is currently active, the result is calculated assuming that the unit's owner is currently active. For this reason this never returns orb_status::enemy nor orb_status::allied.

◆ would_be_discovered()

bool display_context::would_be_discovered	(	const map_location &	loc,

	)

Given a location and a side number, indicates whether an invisible unit of that side at that location would be revealed (perhaps ambushed), based on what team side_num can see.

If see_all is true then the calculation ignores fog, and enemy ambushers.
