Collision detection with InfiniteTerrain Generator
I am wondering if there is anyway to activate collision detection with the infinite terrain generator (InfiniteTerrain.dlc). Given below is a simple example of code, and if you copy/paste and run it in vizard you will see that the ball falls straight through the infinite plane without colliding with it. Anyone Have any suggestions?
import viz viz.go() #Turn on the physics engine viz.phys.enable() viz.MainView.setPosition([0,180,0]) viz.MainView.setEuler( [0,40,0] ) viz.MainView.getHeadLight().disable() #add sun-like directional light l = viz.addLight() l.position(0, 1, -.2, 0) #sets light direction terrain = viz.add('InfiniteTerrain.dlc',1,'300',6,7,15000,0. 001) grass = viz.addTexture('gb_noise.jpg') terrain.texture(grass) terrain.collideMesh() ball = viz.add('ball.wrl') ball.collideBox(density=5) ball.setScale([50,50,50]) ball.setPosition([0,100,100])[/COLOR] |

Also, I am trying to have the view point "walk" along the surface of the terrain generated by the InfiniteTerrain.dlc at a fixed height (let's say, the height of an avatar). I would like to move in the x and z directions with the arrows on the keyboard, while the viewpoint adjusts to the proper height about the terrain. Does anyone have any idea how to do this? Given below is the viewpoint controls that I have been using.
# Viewpoint keyboard controls #%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%% ## Turn off built-in mouse navigation #viz.mouse(viz.OFF) ## Hide mouse cursor #viz.mouse.setVisible(False) MOVE_SPEED = 19 TURN_SPEED = 60 male = viz.addAvatar( 'vcc_male.cfg' ) male.scale([10,10,10]) #male.collideCapsule() viz.MainView.setPosition(0,terrainmaker.terrainfun c(0,0)+17,0) viz.MainView.setEuler([0,0,0]) ## Extract the main viewpoint view = viz.MainView ## Make function which calls back for keyboard event pos_init = view.getPosition() def updatemale(): if viz.key.isDown('d'): view.move([0,-MOVE_SPEED*viz.elapsed(),0],viz.BODY_ORI) if viz.key.isDown('f'): view.move([0,MOVE_SPEED*viz.elapsed(),0],viz.BODY_ORI) if viz.key.isDown(viz.KEY_UP): male.state(2) view.move([0,0,MOVE_SPEED*viz.elapsed()],viz.BODY_ORI) if viz.key.isDown(viz.KEY_RIGHT): view.setEuler([TURN_SPEED*viz.elapsed(),0,0],viz.BODY_ORI,viz.REL_PARENT) elif viz.key.isDown(viz.KEY_LEFT): view.setEuler([-TURN_SPEED*viz.elapsed(),0,0],viz.BODY_ORI,viz.REL_PARENT) elif viz.key.isDown(viz.KEY_DOWN): male.state(2) view.move([0,0,-MOVE_SPEED*viz.elapsed()],viz.BODY_ORI) if viz.key.isDown(viz.KEY_RIGHT): view.setEuler([TURN_SPEED*viz.elapsed(),0,0],viz.BODY_ORI,viz.REL_PARENT) elif viz.key.isDown(viz.KEY_LEFT): view.setEuler([-TURN_SPEED*viz.elapsed(),0,0],viz.BODY_ORI,viz.REL_PARENT) elif viz.key.isDown(viz.KEY_RIGHT): view.setEuler([TURN_SPEED*viz.elapsed(),0,0],viz.BODY_ORI,viz.REL_PARENT) if viz.key.isDown(viz.KEY_UP): male.state(2) view.move([0,0,MOVE_SPEED*viz.elapsed()],viz.BODY_ORI) elif viz.key.isDown(viz.KEY_DOWN): male.state(2) view.move([0,0,-MOVE_SPEED*viz.elapsed()],viz.BODY_ORI) elif viz.key.isDown(viz.KEY_LEFT): view.setEuler([-TURN_SPEED*viz.elapsed(),0,0],viz.BODY_ORI,viz.REL_PARENT) if viz.key.isDown(viz.KEY_UP): male.state(2) view.move([0,0,MOVE_SPEED*viz.elapsed()],viz.BODY_ORI) elif viz.key.isDown(viz.KEY_DOWN): male.state(2) view.move([0,0,-MOVE_SPEED*viz.elapsed()],viz.BODY_ORI) # Attach the male to the viewpoint BODY_ORI male.setPosition(view.getPosition()) male.setEuler(view.getEuler(viz.BODY_ORI)) male.setPosition([0,0,25],viz.REL_LOCAL) #[0.35,-1.7,-0.13] |

Hi Andrew,
The walkTo function accepts an object (node) as the 'y' argument allowing the avatar to follow it precisely - as explained in this post: http://forum.worldviz.com/showthread...ghlight=walkTo |
