object leave the collision

[loway]

hi,

in 3D, i can use the collision to check the object hit the zone.....(zone = 1)

but, how can i detect the 3d object "leave" a collision? (zone = 0)

sensor_01.addModifier(#collision)
sensor_01.collision.mode = #box

sensor_01.collision.enabled=true -- collision function active
sensor_01.collision.resolve= false
sensor_01.collision.setCollisionCallBack(#collisio n, (member"collision"))

on collision (me)
zone = 1
end




thanks
