I was able to make my view move and rotate correctly, but the problem is that I can't fix my view to be beside the avatar's head. and I also want to press a key for example 'r' and move the character to a certain point but anything I tried didn't work at all.
Please take a look at my 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): Quote:
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(0,-0.35,0,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) Last edited by nlfrnassimi; 03-11-2009 at 11:24 PM. |
