static int AiFindTarget	(	const CUnit *	unit,
		unsigned char *	matrix,
		int *	dx,
		int *	dy,
		int *	ds
	)			[static]

Find possible targets.

Parameters:

	unit	Attack.
	matrix	Water matrix.
	dx	Attack point X.
	dy	Attack point Y.
	ds	Attack state.

Returns:

True if target found.

static void AiMarkWaterTransporter	(	const CUnit *	unit,
		unsigned char *	matrix
	)			[static]

Mark all by transporter reachable water tiles.

Parameters:

	unit	Transporter
	matrix	Water matrix.

Note:

only works for water transporters!

int AiPlanAttack

(

AiForce *

force

)

< Plan the an attack

Plan an attack with a force. We know, that we must use a transporter.

Parameters:

force

Pointer on the force.

Returns:

True if target found, false otherwise.

Todo:

Perfect planning. Only works for water transporter!

Todo:

transporter are more selective now (flag with unittypeland). We must manage it.
