point1 | The start of the capsule. |
point2 | The end of the capsule. |
radius | The radius of the capsule. |
direction | The direction into which to sweep the capsule. |
distance | The length of the sweep. |
layerMask | A Layer mask that is used to selectively ignore colliders when casting a capsule. |
Like Physics.CapsuleCast, but this function will return all hits the capsule sweep intersects.
radius
around point1
and point2
, which form the two ends of the capsule.
Hits are returned all colliders which would collide against this capsule if the capsule was moved along direction
.
This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size,
such as a character, will be able to move somewhere without colliding with anything on the way.Notes: The capsule cast does not work against colliders configured as triggers.
If you move colliders from scripting or by animation, there needs to be at
least one FixedUpdate executed so that the physics library can update it's data
structures, before a capsule cast will hit the collider at it's new position.See Also: Physics.SphereCast, Physics.CapsuleCast, Physics.Raycast, Rigidbody.SweepTest.function Update () { var hits : RaycastHit[]; var charCtrl : CharacterController = GetComponent(CharacterController); var p1 : Vector3 = transform.position + charCtrl.center + Vector3.up * (-charCtrl.height*0.5); var p2 : Vector3 = p1 + Vector3.up * charCtrl.height; // Cast character controller shape 10 meters forward, to see if it is about to hit anything hits = Physics.CapsuleCastAll (p1, p2, charCtrl.radius, transform.forward, 10); // Change the material of all hit colliders // to use a transparent Shader for (var i = 0;i < hits.Length;i++) { var hit : RaycastHit = hits[i]; var renderer = hit.collider.renderer; if (renderer) { renderer.material.shader = Shader.Find("Transparent/Diffuse"); renderer.material.color.a = 0.3; } } }
