int move_ob	(	object *	op,
		int	dir,
		object *	originator
	)

Op is trying to move in direction dir.

Parameters

op	what is moving.
dir	what direction op wants to move.
originator	typically the same as op, but can be different if originator is causing op to move (originator is pushing op).

Return values

0	op is not able to move to the desired space.
1	op was moved.

int move_object	(	object *	op,

	)

Try to move op in the direction "dir".

Parameters

op	what to move.
dir	moving direction.

Return values

0	something blocks the passage.
1	op was moved..

int move_to	(	object *	op,
		int	x,
		int	y
	)

Move an object one square toward a specified destination on the same map. The move takes into account blocked squares for op, and things like that. No check is done to know if the object has enough speed to move.

Parameters

op	object to move
x
y	destination coordinates

Returns: 0 if op is on the specified spot, 1 if it moved towards the goal, 2 if it didn't find any path to the goal.

int push_ob	(	object *	who,

	)

Something is pushing some other object.

Parameters

who	object being pushed.
dir	pushing direction.
pusher	what is pushing who.

Return values

1	if pushing invokes a attack
0	no attack during pushing.

Todo:: fix return value which is weird for last case.

static

An object is being pushed, and may push other objects.

This is not perfect yet. it does not roll objects behind multipart objects properly. Support for rolling multipart objects is questionable.

Parameters

op	what is being pushed.
dir	pushing direction.
pusher	what is pushing op.

Return values

0	op couldn't move.
1	op, and potentially other objects, moved.

int teleport	(	object *	teleporter,
		uint8	tele_type,
		object *	user
	)

Teleport an item around a nearby random teleporter of specified type.

It is basically used so that shop_mats and normal teleporters can be used close to each other and not have the player put to the one of another type.

Parameters

teleporter	what is teleporting user.
tele_type	what object type user can be put on. this is either set to SHOP_MAT or TELEPORTER.
user	what object to teleport.

Return values

1	user was destroyed.
0	user is still valid, but may have moved or not.

Todo:: fix weird return values.

Does nothing if there is no free spot.

Parameters

op	what to move.
x
y	new coordinates.
randomly	if true, use find_free_spot() to find the destination, otherwise use find_first_free_spot().
originator	what is causing op to move.

Return values

1	op was destroyed.
0	op was moved.

Checks if an objects fits on a specified spot.

This is a new version of blocked, this one handles objects that can be passed through by monsters with the CAN_PASS_THRU defined.

Very new version handles also multipart objects This is currently only used for the boulder roll code.

Parameters

op	what object to fit.
m
x
y	where to put op.

Return values

1	object does not fit.
0	object fits.
