unity 的一些API-01

Posted 2020-10-10 redlkop

public static float GetAxis(string axisName);

看下原话解释:

Returns the value of the virtual axis identified by axisName.

The value will be in the range -1...1 for keyboard and joystick input. If the axis is setup to be delta mouse movement, the mouse delta is multiplied by the axis sensitivity and the range is not -1...1.

This is frame-rate independent; you do not need to be concerned about varying frame-rates when using this value.

大意:返回一个虚轴的值给对象，这个值在-1到1之间，而鼠标则不是-1到1.      如官方给出的代码:

 

public float speed = 10.0F;

public float rotationSpeed=100.0F;

void()

{float translation = Input.GetAxis("vertical")*speed;

float rotation = Input.GetAxis("Horizontal")*rotationSpeed;

translation*=Time*deltaTime;

rotation*=Time.deltaTime;

transform.Translate(0,0,translation);

transform.Rotate(0,rotation,0);
