手机重力感应代码

{
dir.x = Input.GetAxis("Horizontal");
dir.y = Input.GetAxis("Vertical");
}
else
{
dir.x = Input.acceleration.x;
function FixedUpdate () {
var dir : Vector3 = Vector3.zero;
if (simulateAccelerometer)
{
// using joystick input instead of iPhone accelerometer
//初始化赋值
cross_x = Screen.width - round.width;
cross_y = Screen.height - round.height;
}
function OnGUI () {
//整体显示 x y z 重力感应的重力分量
if (dir.sqrMagnitude > 1)
dir.Normalize();
}
rigidbody.AddForce(dir * force);
}
//--------------------------------------------------------------------------------------------------
dir.Normalize();
}
rigidbody.AddForce(dir * force);
}

个人感觉方案一操控起来比较灵活，反应灵敏。方案二操控起来具有惯性，缓冲明显。
//--------------------------------------------------------------------------------------------------
var dir : Vector3 = Vector3.zero;
if (simulateAccelerometer)
{
// using joystick input instead of iPhone accelerometer
dir.x = Input.GetAxis("Horizontal");
//--------------------------------------------------------------------------------------------------
方案一：speed
public var simulateAccelerometer:boolean = false;
x = 0;
}else if(x > cross_x){; 0){
y = 0;
}else if(y > cross_y){
y = cross_y;
}
}
//--------------------------------------------------------------------------------------------------
过Input.acceleration去拿到当前手机的重力感应分量
// Move object
transform.Translate (dir * speed);
}
也可以把速度换成力
方案二：Force
public var force:float = 1.0;
public var simulateAccelerometer:boolean = false;
//根据重力分量修改小球的位置这里乘以30的意思是让小球移动的快一些
x += Input.acceleration.x * 30;
y += -Input.acceleration.y * 30;
//避免小球超出屏幕
if(x < 0){
// 2) rotated 90 degrees around Y axis
dir.x = Input.acceleration.y;
dir.y = Input.acceleration.x;
// clamp acceleration vector to unit sphere
dir.x = Input.GetAxis("Horizontal");
dir.y = Input.GetAxis("Vertical");
}
else
{
// we assume that device is held parallel to the ground
// and Home button is in the right hand
// remap device acceleration axis to game coordinates
// 1) XY plane of the device is mapped onto XZ plane
dir.x = Input.acceleration.y;
dir.y = Input.acceleration.x;
// clamp acceleration vector to unit sphere
if (dir.sqrMagnitude > 1)
dir.y = Input.acceleration.y;
// clamp acceleration vector to unit sphere
if (dir.sqrMagnitude > 1)
dir.Normalize();
bel(Rect(0,0,480,100),"position is " + Input.acceleration);
//绘制小球
GUI.DrawTexture(Rect(x,y,256,256),round);
}
function Update(){
}
