kind of a noob question…
I am trying to use the script to control my own model, here is the code :
class FPS(object,DirectObject):
def __init__(self):
self.initCollision()
self.loadLevel()
self.initPlayer()
self.camera()
def initCollision(self):
#initialize traverser
base.cTrav = CollisionTraverser()
base.cTrav.setRespectPrevTransform(True)
# base.cTrav.showCollisions(render)
#initialize pusher
self.pusher = CollisionHandlerPusher()
# collision bits
self.groundCollBit = BitMask32.bit(0)
self.collBitOff = BitMask32.allOff()
def loadLevel(self):
level = loader.loadModel('mine/road.egg')
level.reparentTo(render)
level.setPos(-10,-10,-6)
level.setColor(1,1,1,.5)
level.setScale(10)
def initPlayer(self) :
self.man = Actor("mine/toxotis",
{"run":"mine/toxotis_run",
"walk":"mine/toxotis_idle"})
self.man.reparentTo(render)
self.man.setScale(1)
#self.man.setPos(0,0,-0.02)
#create a collsion solid around the man
manC = self.man.attachCollisionSphere('manSphere', 0,0,1, .4, self.groundCollBit,self.collBitOff)
self.pusher.addCollider(manC,self.man)
base.cTrav.addCollider(manC,self.pusher)
speed = 6
Forward = Vec3(0,-speed*2,0)
Back = Vec3(0,speed,0)
Left = Vec3(-speed,0,0)
Right = Vec3(speed,0,0)
Stop = Vec3(0)
self.walk = Stop
self.strife = Stop
self.jump = 0
taskMgr.add(self.move, 'move-task')
self.jumping = LerpFunc( Functor(self.__setattr__,"jump"),
duration=.25, fromData=.25, toData=0)
self.accept( "escape",sys.exit )
self.accept( "space" , self.startJump)
self.accept( "s" , self.__setattr__,["walk",Back] )
self.accept( "w" , self.__setattr__,["walk",Forward])
self.accept( "s-up" , self.__setattr__,["walk",Stop] )
self.accept( "w-up" , self.__setattr__,["walk",Stop] )
self.accept( "a" , self.__setattr__,["strife",Left])
self.accept( "d" , self.__setattr__,["strife",Right] )
self.accept( "a-up" , self.__setattr__,["strife",Stop] )
self.accept( "d-up" , self.__setattr__,["strife",Stop] )
self.manGroundColNp = self.man.attachCollisionRay( 'manRay',
0,0,.6, 0,0,-1,
self.groundCollBit,self.collBitOff)
self.manGroundHandler = CollisionHandlerGravity()
self.manGroundHandler.addCollider(self.manGroundColNp,self.man)
base.cTrav.addCollider(self.manGroundColNp, self.manGroundHandler)
def startJump(self):
if self.manGroundHandler.isOnGround():
self.jumping.start()
def move(self,task):
dt=globalClock.getDt()
# mouse
md = base.win.getPointer(0)
x = md.getX()
y = md.getY()
# move where the keys set it
moveVec=(self.walk+self.strife)*dt # horisontal
moveVec.setZ( self.jump ) # vertical
self.man.setFluidPos(self.man,moveVec)
# jump damping
if self.jump>0:
self.jump = clampScalar( 0,1, self.jump*.9 )
# If man is moving, loop the run animation.
# If he is standing still, stop the animation.
if self.walk == Forward:
self.man.loop("run")
return task.cont
def camera(self) :
# Create a floater object. We use the "floater" as a temporary
# variable in a variety of calculations.
#self.floater = NodePath(PandaNode("floater"))
#self.floater.reparentTo(render)
# Set up the camera
#base.disableMouse()
#base.camera.setPos(-100,-20,20)
#base.camera.setPos(self.man.getX(),self.man.getY()+10,2)
# If the camera is too far from ralph, move it closer.
# If the camera is too close to ralph, move it farther.
camvec = self.man.getPos() - base.camera.getPos()
camvec.setZ(0)
camdist = camvec.length()
camvec.normalize()
if (camdist > 10.0):
base.camera.setPos(base.camera.getPos() + camvec*(camdist-10))
camdist = 10.0
if (camdist < 5.0):
base.camera.setPos(base.camera.getPos() - camvec*(5-camdist))
camdist = 5.0
# The camera should look in ralph's direction,
# but it should also try to stay horizontal, so look at
# a floater which hovers above ralph's head.
#self.floater.setPos(self.man.getPos())
#self.floater.setZ(self.man.getZ() + 2.0)
base.camera.lookAt(self.man)
return Task.cont
FPS()
render.setShaderAuto()
run()
I now try to loop the animation of the model and I go to the move function, and I say :
if self.walk == Forward:
self.man.loop("run")
An error is produced because Forward is not a global variable. I realize that is only declared in the function initplayer. How can i declare it glabally?
thanx!
