Function Documentation

static int anim_compare	(	const Animations *	a,
		const Animations *	b
	)		[static]

Utility function to compare 2 animations based on their name.

Used for sorting/searching.

Definition at line 134 of file anim.c.

References animations_struct::name.

Referenced by try_find_animation().

Here is the caller graph for this function:

void animate_object	(	object *	op,
		int	dir
	)

Updates the face-variable of an object.

If the object is the head of a multi-object, all objects are animated. The object's state is not changed, but merely updated if needed (out of bounds of new animation, reached end of animation, ...)

Parameters:

op	is the object to animate.
dir	is 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.
