Prevent users from "walking" into 3D models

  • You could get the world position of the camera and the object, then do a distance check to see if they are colliding. From there maybe you can have text popup saying back up or just hide the house.

     

    The code below is a simple example of collision detection, if you allow the user to resize the house you may have to make the collision zone grow/shrink as well. Hopefully this can put you on the right path.

    The collision zone is a number which is compared to the distance, if the distance from the camera to the object is less or equal to the collision zone then we are colliding.

    //@input float collisionZone
    //@input SceneObject worldObject
    //@input Component.Camera cam

    var colliding = false

    var event = script.createEvent('UpdateEvent')
    event.bind(function(eventData) {

      // Get Camera Position

      var camPos = script.cam.getTransform().getWorldPosition()

      // Get Object Position

      var objectPos = script.worldObject.getTransform().getWorldPosition()

      // Get Distance from Camera to Object

      var dist = camPos.distance(objectPos)

      // If the distance is less than or equal to the collision zone size, we are colliding

      if (dist <= script.collisionZone) {

        colliding = true

      } else {

    colliding = false

    }

    })
