◆ action_actor_utype_hard_reqs_ok()

bool action_actor_utype_hard_reqs_ok	(	const struct action *	paction,
		const struct unit_type *	actor_unittype
	)

Returns TRUE if the specified unit type can perform the specified action given that an action enabler later will enable it.

This is done by checking the action result's hard requirements. Hard requirements must be TRUE before an action can be done. The reason why is usually that code dealing with the action assumes that the requirements are true. A requirement may also end up here if it can't be expressed in a requirement vector or if its absence makes the action pointless.

Parameters

paction	the action to check the hard reqs for
actor_unittype	the unit type that may be able to act

Returns: TRUE iff the specified unit type can perform the wanted action given that an action enabler later will enable it.

Returns TRUE if the specified unit type can perform the specified action given that an action enabler later will enable it.

This is done by checking the action result's hard requirements. Hard requirements must be TRUE before an action can be done.

Parameters

paction	the action to check the hard reqs for
actor_unittype	the unit type that may be able to act
ignore_third_party	ignore if potential targets etc exists

Returns: TRUE iff the specified unit type can perform the wanted action given that an action enabler later will enable it.

Find out if the action is enabled, may be enabled or isn't enabled given what the player owning the actor knowns.

A player don't always know everything needed to figure out if an action is enabled or not. A server side AI with the same limits on its knowledge as a human player or a client should use this to figure out what is what.

Assumes to be called from the point of view of the actor. Its knowledge is assumed to be given in the parameters.

Returns TRI_YES if the action is enabled, TRI_NO if it isn't and TRI_MAYBE if the player don't know enough to tell.

If meta knowledge is missing TRI_MAYBE will be returned.

target may be NULL. This is equivalent to passing an empty context.

◆ action_enabler_possible_actor()

bool action_enabler_possible_actor ( const struct action_enabler * ae )

Returns TRUE iff the specified action enabler may have an actor that it may be enabled for in the current ruleset.

		const struct city *	homecity
	)

static

Returns if the wanted action is possible given that an action enabler later will enable it.

Can return maybe when not omniscient. Should always return yes or no when omniscient.

This is done by checking the action's hard requirements. Hard requirements must be fulfilled before an action can be done. The reason why is usually that code dealing with the action assumes that requirements are true. A requirement may also end up here if it can't be expressed in a requirement vector or if its absence makes the action pointless.

When adding a new hard requirement here: explain why it is a hard requirement in a comment. remember that this is called from action_prob(). Should information the player don't have access to be used in a test it must check if the evaluation can see the thing being tested.

Passing NULL for actor or target is equivalent to passing an empty context. This may or may not be legal depending on the action.
