            (This document covers version 3.3.2 of the 'Collider for Walkthroughs' behavior, current as of 2005-Feb-11)
           

            Description
           


             Attach this behavior to an object to cause it to collide with any objects which have the Collision Shell behavior attached.
            

             When an object collides with a collision shell:
            


              the Collision Shell fires a ‘Collided With’ event
            

              this behavior fires a
              
               Collided
              
              event
            


             This behavior is designed to be placed on a Camera or other other object which is controlled by a behavior like ‘Fly’ or ‘Walk’. It prevents the object from penetrating any collision shells, and (unlike Collider for Simulations) does so without ‘reflecting’ the parent object.
            

             The parent object must be in ‘global space’ for this behavior to work properly. If it is placed inside any parent object which is scaled, rotated, of offset, this behavior will not work as expected.
            

             While the geometry of the collision shells are used to find the collision, the geometry of the Collider object is
            
              NOT
            
             used. Instead, the
            
              Collision Distance
            
             property is used to set up rays which extend in front of the object (along the direction of movement) radiating from the ‘center’ (pivot point) of the object out to the distance specified by the
            
              Radius
            
             property. As the object is moved, these rays test whether or not the parent object has hit any Collision Shell.
            

             It does not matter whether the parent object is moved due to its position velocity, animation or script setting its position directly; the difference in position of the object is used in all cases to determine that it has moved.
            

             Unlike the Collider for Simulations behavior, this behavior does not use the
            
              Elasticity
            
             setting for collision shells.
            

             Finally, note that the collision detection is only based on the movement of the collider,
            
              NOT
            
             the collision shell. If you have the collider sitting still and you move/rotate a collision shell into it (for example, a moving wall) the collider may not experience a collision.
            


            Basic Properties
           



              Collision Distance
            

              How far from the center of the parent should a collision be looked for?
            



            Advanced Properties
           



              Stay in XZ?
            

              Never affect the global Y position of the parent? (Needed with 'Walk')
            



            Events
           



              Collided
            

              Fires when the parent object collides with a collision shell.
