Help Creating Interactive City Env from .dae

[vJimZ]

Hi everyone,

I'm fairly new to Vizard, and am having trouble making the environment map of a city interactive.

The environment map is loaded from a .dae file, and contains the ground floor as well as a sea layer above it, and some buildings.

I have an avatar moving around the world, controlled by arrow keys.

I would like to make it so that the user cannot collide with either the buildings and the sea areas.
I tried collisionMesh, collisionBox, and collisionSphere on both the avatar and the environ map variable and they do not work; the avatar simply walks through them. When I try a simple line like printing "collide" on collision, nothing happens.

My code is:
--------------------------------------------------------------------------
import necessary files

viz.go()
viz.clearcolor(viz.SKYBLUE)
viz.phys.enable()

#Resources

#Builds the basic background resources
city = viz.add('art/city.dae')
city.setScale([.01,.01,.01])
city.collideMesh()
viz.collision(viz.ON)
viz.collisionbuffer(0.3)

#######Add avatar details here###############
male = viz.add('vcc_male.cfg')
male.setPosition([10.0, 0, 40.0])
male.collideMesh()

### Sets the position to be just behind the avatar
matrixPos = male.getPosition()
matrixPos[2] = matrixPos[2] - 10
viz.MainView.setPosition(matrixPos)

## other functions here that account for movement####
