Parameters

op	living thing throwing something.
part	part of op throwing.
toss_item	item thrown.
dir	direction to throw.
skill	throwing skill.

Return values

0	skill use failed.
1	skill was successfully used.

Todo:: this messy function should probably be simplified.

Fixed logic here

The old code made you have a better factor the more encumbered past the LOAD_PCT you were. This new way essentially flips the variable to be higher at lower encumbrance.

It also only encumbers throwing once carryng more than FREE_PLAYER_LOAD_PERCENT of our capacity, since we have a MIN on load_factor when we use it, so before the limit it is clipped to 1.0.

Also ,use 2.0f since op->carrying/(get_weight_limit(op->stats.Str)*FREE_PLAYER_LOAD_PERCENT) = 1 if they are equal. As op->carrying increases, this slides higher, making the factor lower.

◆ identify_object_with_skill()

int identify_object_with_skill	(	object *	tmp,

Helper function for do_skill_ident, so that we can loop over inventory AND objects on the ground conveniently.

Identification will be attempted as many times as NROF(tmp), and tmp will be split if needed. This is to allow players to maximise experience for identification without having to resort to picking one item, moving, attempting identification of the item, and such.

See https://sourceforge.net/p/crossfire/feature-requests/244/

Parameters

tmp	object to try to identify.
pl	object identifying.
skill	identification skill.
print_on_success	1 to print a description if the object is identified, 0 to leave it to the calling function

Returns: experience for successful identification.
