Parameters
opis the object to animate.
diris the direction the object is facing. This is generally same as op->direction, but in some cases, op->facing is used instead - the caller has a better idea which one it really wants to be using, so let it pass along the right one.

The main purpose of calling this function is the messages that are displayed - fix_object should really always be called after this when removing an object - that is because it is impossible to know if some object is the only source of an attacktype or spell attunement, so this function will clear the bits, but the player may still have some other object that gives them that ability.

Checks whether the altar has enough to sacrifice.

Function put in (0.92.1) so that identify altars won't grab money unnecessarily - we can see if there is sufficient money, see if something needs to be identified, and then remove money if needed.

0.93.4: Linked objects (ie, objects that are connected) can not be sacrificed. This fixes a bug of trying to put multiple altars/related objects on the same space that take the same sacrifice.

The function will now check for all items sitting on the altar, so that the player can put various matching but non merging items on the altar.

This function can potentially remove other items, if remove_others is set.

Parameters
altaritem to which there is a sacrifice
sacrificeobject that may be sacrifed
remove_othersif 1, will remove enough items apart sacrifice to compensate for not having enough in sacrifice itself.
[out]toremovewill contain the nrof of sacrifice to really remove to finish operating. Will be set if not NULL only if the function returns 1.

object* check_inv_recursive ( object op,

Checks object and its inventory for specific item.

It will descend through containers to find the object. slaying = match object slaying flag race = match object archetype name flag hp = match object type (excpt type '0'== PLAYER) title = match object title Searching by title only is not recommended, as it can be a rather slow operation; use it in combination with archetype or type.

Parameters
opobject of which to search inventory
trigwhat to search
Returns
object that matches, or NULL if none matched.

Checks if any objects has a move_type that matches objects that effect this object on this space. Call apply() to process these events.

Any speed-modification due to SLOW_MOVE() of other present objects will affect the speed_left of the object. 4-21-95 added code to check if appropriate skill was readied - this will permit faster movement by the player through this terrain. -b.t.

MSW 2001-07-08: Check all objects on space, not just those below object being inserted. insert_ob_in_map may not put new objects on top.

Parameters
opobject that may trigger something.
originatorplayer, monster or other object that caused 'op' to be inserted into 'map'. May be NULL.
Returns
1 if 'op' was destroyed, 0 otherwise.

int check_path ( const char *  name,
int  prepend_dir 
)

This function checks if a file with the given path exists.

It tries out all the compression suffixes listed in the uncomp[] array, except for Windows which checks an exact file.

Parameters
namemap path to check.
prepend_dirIf set, then we call create_pathname (which prepends libdir & mapdir). Otherwise, we assume the name given is fully complete.
Returns
-1 if it fails, otherwise the mode of the file is returned.
Note
Only the editor actually cares about the writablity of this - the rest of the code only cares that the file is readable. when the editor goes away, the call to stat should probably be replaced by an access instead (similar to the windows one, but that seems to be missing the prepend_dir processing

Use this function if player created an object (e.g. fire bullet, swarm spell), and this object creates further objects whose kills should be accounted for the player's original skill, even if player has changed skills meanwhile.

namethe name we're searching for (ex: "writing pen"), must not be null
Returns
a corresponding object if found; a singularity object if not found.
Note
Note by MSW - it appears that it takes the full name and keeps shortening it until it finds a match. I re-wrote this so that it doesn't malloc it each time - not that this function is used much, but it otherwise had a big memory leak.
