|
|
Actor constructor: can be used to create single or multipart
|
|
actors. If another Actor is supplied as an argument this
|
|
method acts like a copy constructor. Single part actors are
|
|
created by calling with a model and animation dictionary
|
|
(animName:animPath{}) as follows:
|
|
|
|
a = Actor("panda-3k.egg", {"walk":"panda-walk.egg" \
|
|
"run":"panda-run.egg"})
|
|
|
|
This could be displayed and animated as such:
|
|
|
|
a.reparentTo(render)
|
|
a.loop("walk")
|
|
a.stop()
|
|
|
|
Multipart actors expect a dictionary of parts and a dictionary
|
|
of animation dictionaries (partName:(animName:animPath{}){}) as
|
|
below:
|
|
|
|
a = Actor(
|
|
|
|
# part dictionary
|
|
{"head":"char/dogMM/dogMM_Shorts-head-mod", \
|
|
"torso":"char/dogMM/dogMM_Shorts-torso-mod", \
|
|
"legs":"char/dogMM/dogMM_Shorts-legs-mod"} , \
|
|
|
|
# dictionary of anim dictionaries
|
|
{"head":{"walk":"char/dogMM/dogMM_Shorts-head-walk", \
|
|
"run":"char/dogMM/dogMM_Shorts-head-run"}, \
|
|
"torso":{"walk":"char/dogMM/dogMM_Shorts-torso-walk", \
|
|
"run":"char/dogMM/dogMM_Shorts-torso-run"}, \
|
|
"legs":{"walk":"char/dogMM/dogMM_Shorts-legs-walk", \
|
|
"run":"char/dogMM/dogMM_Shorts-legs-run"} \
|
|
})
|
|
|
|
In addition multipart actor parts need to be connected together
|
|
in a meaningful fashion:
|
|
|
|
a.attach("head", "torso", "joint-head")
|
|
a.attach("torso", "legs", "joint-hips")
|
|
|
|
#
|
|
# ADD LOD COMMENT HERE!
|
|
#
|
|
|
|
Other useful Actor class functions:
|
|
|
|
#fix actor eye rendering
|
|
a.drawInFront("joint-pupil?", "eyes*")
|
|
|
|
#fix bounding volumes - this must be done after drawing
|

#the actor for a few frames, otherwise it has no effect
