charactor controller 角色平衡木问题解决办法
Posted on 2013 年 06 月 13 日 by U3d / Unity3D 脚本/插件/被围观 37 次
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("Horizontal"), 0,
Input.GetAxis("Vertical"));
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("Jump"))
