The timer property class implements a simple timer.
iPcTimer
PcTimer can be used if you want an entity to wake up every frame, after a while or at certain time lapses.
Currently it has two different timing modes called WakeUp
and WakeUpFrame
. This can be set either through pcclass actions (from map or blxml), or
by using the iPcTimer interface (for c++ or python).
With WakeUp mode a specific lapse of time can be defined, and the entity holding
this property class will receive the ‘pctimer_wakeup’ message once it is
elapsed. Also repeat
can be defined, and then the timer will keep sending
the message each time the time lapse expires, otherwise the timer will be
cleared afterwards.
WakeUpFrame
wakes the entity either after or before each frame is drawn, this
is best for continuously updating parameters from the entity with this property
class when used before the frame, or drawing/post processing when used after
the frame is drawn.
It allows for one parameter for specifying at what moment entity will be woken up, possible values are:
This mode sends the ‘pctimer_wakeupframe’ message to the entity at the requested moment with two parameters: ‘elapsedticks’ and ‘currentticks’.
To define an entity that uses this property class we add a <propclass> stance to the entity or entity template <addon> section.
<addon entityname="FinalMonster" plugin="cel.addons.celentity"> <propclass name="pctools.timer"> <action name="WakeUp"> <par name="time" long="14.0"/> <par name="repeat" bool="true"/> </action> </propclass> <propclass name="pcobject.mesh"> <action name="SetMesh"> <par string="EvilMonster" name="name"/> </action> </propclass> <behaviour layer="blpython" name="lookat"/> </addon> |
