◆ add_capacity()

static void add_capacity ( const object op,
StringBuffer buf,
int  previous_sp 
)
static

Add the capacity of the crystal to the buffer. Sentence will be dot-terminated.

Parameters
opcrystal to add the capacity of.
bufwhere to put the capacity.
previous_spif -1 then ignored, else previous sp of the crystal to add 'still ' or 'now ' to the message to signal level changes.

◆ power_crystal_type_apply()

static method_ret power_crystal_type_apply ( object op,
object applier,
int  aflags 
)
static

This function handles the application of power crystals. Power crystals, when applied, either suck power from the applier, if he's at full spellpoints, or gives him power, if it's got spellpoins stored.

Parameters
opThe power crystal to apply
applierThe object applying the crystal
aflagsSpecial flags (always apply/unapply)
Returns
The return value is always METHOD_OK
