charactor controller角色平衡木问题解决办法
charactor controller角色做平衡木的问题，和小球走平衡木不一样，charctor controller是不可以对地面产生压力的，无论角色是否加了刚体，charactor controller都只具有自由下落，而不具有对地面压力。如果换成box collider等碰撞检测，上下楼梯角色运动的时候很容易倒下。针对这个问题，做出了以下解决方案：

01
var speed = 10.0;
02
var gravity = 10.0;
03
var maxVelocityChange = 10.0;
04
var canJump = true;
05
var jumpHeight = 2.0;
06
private var grounded = false;
07
08
@script RequireComponent(Rigidbody, CapsuleCollider)
09
10
function Awake ()
11
{
12
rigidbody.freezeRotation = true;
13
rigidbody.useGravity = false;
14
}
15
16
function FixedUpdate ()
17
{
18
if (grounded)
19
{
20
// Calculate how fast we should be moving
21
var targetVelocity = new Vector3(Input.GetAxis(&#34;Horizontal&#34;), 0, Input.GetAxis(&#34;Vertical&#34;));
22
      targetVelocity = transform.TransformDirection(targetVelocity);
23
      targetVelocity *= speed;
24
25
// Apply a force that attempts to reach our target velocity
26
var velocity = rigidbody.velocity;
27
var velocityChange = (targetVelocity - velocity);
28
      velocityChange.x = Mathf.Clamp(velocityChange.x, -maxVelocityChange, maxVelocityChange);
29
      velocityChange.z = Mathf.Clamp(velocityChange.z, -maxVelocityChange, maxVelocityChange);
30
      velocityChange.y = 0;
31
      rigidbody.AddForce(velocityChange, ForceMode.VelocityChange);
32
33
// Jump
34
if (canJump && Input.GetButton(&#34;Jump&#34;))
35
      {Unity3D教程手册
36
         rigidbody.velocity = Vector3(velocity.x, CalculateJumpVerticalSpeed(), velocity.z);
37
      }
38
}
39
40
// We apply gravity manually for more tuning control
41
rigidbody.AddForce(Vector3 (0, -gravity * rigidbody.mass, 0));
42
43
grounded = false;
44
}
45
46
function OnCollisionStay ()
47
{
48
grounded = true;
49
}
50
51
function CalculateJumpVerticalSpeed ()
52
{
53
// From the jump height and gravity we deduce the upwards speed
54
// for the character to reach at the apex.
55
return Mathf.Sqrt(2 * jumpHeight * gravity);
56
}
