WorldViz User Forum - animation path

Hi every one,

I'm doing an application to teach children cross road. I'm trying to get the codes that I need. I have imported a character and placed a camera beside the character to act as first point of view, then I have assigned mouse movement to look around and arrow keys to move the character. I want to press a certain key and animate my character(moving from a point to another), can anyone please tell me how to do it. I have done it before but now combining it with this code it doesn't work.

Here is the code :

Code:

import viz



viz.go()



viz.clearcolor(0.5,0.5,1) 

  

MOVE_SPEED = 5 # how fast the viewpoint move

TURN_SPEED = 60 # how fast the view point rotate



viz.add('tut_ground.wrl')

char = viz.add('vcc_male.cfg') 

char.state(1)



view = viz.MainView

view.setPosition(0,1.7,0)

car = viz.add('mini.osgx')

car.translate(5,0,5)



def mytimer(num):

        if viz.iskeydown(viz.KEY_DOWN):

                view.move(0,0,-MOVE_SPEED*viz.elapsed(),viz.BODY_ORI)

        elif viz.iskeydown(viz.KEY_UP):

                view.move(0,0,MOVE_SPEED*viz.elapsed(),viz.BODY_ORI)

        elif viz.iskeydown(viz.KEY_RIGHT):

                view.rotate(0,1,0,TURN_SPEED*viz.elapsed(),viz.BODY_ORI,viz.REL_PARENT)

        elif viz.iskeydown(viz.KEY_LEFT):

                view.rotate(0,1,0,-TURN_SPEED*viz.elapsed(),viz.BODY_ORI,viz.REL_PARENT)

        updatechar()                

viz.callback(viz.TIMER_EVENT,mytimer) 



viz.starttimer(0,0.01,viz.FOREVER)



def updatechar():



#translate the character to the position of the viewpoint

#  char.translate(view.get(viz.HEAD_POS)) 

#rotate the character to the same orientation as the BODY_ORI.

  char.rotate(view.get(viz.BODY_AXISANGLE))

#move the character beside the view.

  char.translate(1,0,0,viz.REL_LOCAL) #viz.REL_LOCAL. This tells vizard to translate the car relative to its local coordinate system (i.e. relative to the direction the car is facing).





def mousemove(e):

        #gets the Euler angle rotation of the HEAD_ORI

        euler = view.get(viz.HEAD_EULER)

        #adding the x movement of the mouse to the current yaw(we multiply the x movement by 0.1.  This is to decrease the sensitivity of the movement)

        euler[0] += e.dx*0.1

        #adds the y movement of the mouse to the current pitch. We need to negate the value since a positive pitch value means rotating down, but moving the mouse down means having a negative y movement. 

        euler[1] += -e.dy*0.1

        #clamping the pitch value between -90 and 90, since we don't want to let the user look down or up so much that they end up upside down.

        euler[1] = viz.clamp(euler[1],-90.0,90.0)

        #rotating the HEAD_ORI of the viewpoint by the new euler angle rotation

        view.rotate(euler,viz.HEAD_ORI) 

        

viz.callback(viz.MOUSE_MOVE_EVENT,mousemove)

#Turn off built in  mouse

viz.setMouseOverride()

#Hide cursor

viz.cursor(viz.OFF) 



def mousedown(button):

        if button == viz.MOUSEBUTTON_LEFT:

                view.reset(viz.HEAD_ORI)



        elif button == viz.MOUSEBUTTON_RIGHT:

                view.reset(viz.BODY_ORI|viz.HEAD_POS)

        updatechar()



viz.callback(viz.MOUSEBUTTON_EVENT,mousedown)
