WorldViz User Forum - How to create circle like collision area

You can add a function that's called every frame that checks the distance between the object and the center of the circle. Depending on the distance value you'll know whether the object is inside or outside of the circle:

Code:

import viz

import vizact

import vizmat



viz.go()



CIRCLE_CENTER = [0,0,5]

CIRCLE_RADIUS = 2



court = viz.addChild('court.ive')

avatar = viz.addAvatar('vcc_male.cfg')



text = viz.addText('',parent=viz.SCREEN)

text.setPosition(0.3,0.8)

text.color(viz.RED)



walk = vizact.walkTo([0,0,10])

avatar.addAction(walk)



def collisionCheck():

        distance = vizmat.Distance(CIRCLE_CENTER,avatar.getPosition())

        if distance > CIRCLE_RADIUS:

                text.message('Outside circle')

        else:

                text.message('Inside circle')

        

vizact.ontimer(0,collisionCheck)
