Collision detection with specific models
Is it possible to have collision detection on only certain objects? In my specific code, I only want collisions between the subject and either the people avatars or the car.
I've also run into an issue on my keydown functions and I don't know why. Since adding the car model, none of my keydowns work anymore. Would it be because I haven't finished writing the car's keydown function, or is there some other problem that I missed? thanks -Alex Code:
import viz import math import vizmat import vizinfo import vizact from lookingat import LookingAt viz.go(viz.FULLSCREEN) #adds the ppt PORT_PPT = 1 ppt = viz.add('vizppt.dls') ppt.command(3,"",3,1,3) #scales ppt tracking on xyz axis viz.eyeheight(0) #collisions on viz.collision(viz.ON) view = viz.get(viz.MAIN_VIEWPOINT) view.rotate(0,1,0,90) #This function is called when a collision occurs def mycollision(info): print 'Collided' #Create a callback for a collision event viz.callback(viz.COLLISION_EVENT, mycollision) PORT_INTERSENSE = 2 isense = viz.add('intersense.dls') tracker = viz.add('intersense.dls') viz.tracker() tracker.reset() def mykeyboard(key): #If the R key is pressed, reset the head orientation if key in ['r','R']: tracker.reset() #Create a keyboard callback viz.callback(viz.KEYBOARD_EVENT,mykeyboard) #Add the street and drop it a little bit to be below the avatars feet. street = viz.add('objects/bspcity.bsp') street.translate(0,-.2,0) males = [] females = [] walking = [] whichturn = 0 #List the timers.

If you have viewpoint collision on you can disable collision with an object by using
Code:
<node3D>.disable(viz.INTERSECTION) Code:
viz.callback(viz.KEYBOARD_EVENT,mykeyboard) viz.callback(viz.KEYDOWN_EVENT,onkeydown) |
