Unity input and Control

Main concepts:

1. Virtual Axis

2. Enter pre-settings

Example:

Control object movement through keyboard

1 private float speed = 10.0f; // speed 2 3 private float rotaspeed = 100366f; // rotation speed 4 5 // update is called once per frame 6 void Update () {7 8 // obtain the virtual axis in the vertical direction and control W, S 9 float translation = input. getaxis ("vertical") * speed; 10 11 // obtain the virtual axis in the horizontal direction and control a, D12 float rotation = input. getaxis ("horizontal") * rotaspeed; 13 14 // variable by Time Difference 15 translation * = time. deltatime; 16 rotation * = time. deltatime; 17 18 // convert 19 transform. translate (0, 0, translation); 20 transform. rotate (0, rotation, 0); 21}

 

Note:

rotation *= Time.deltaTime;

To obtain the moving effect (smoothness) unrelated to the refresh frame rate)

 

3. keyboard Detection

Getkey and getbutton

Two getkey methods:

if (Input.GetKey(KeyCode.UpArrow))        {            print("get up");        }

if (Input.GetKey(“up”))        {            print("get up");        }

Getbutton method:

if(Input.GetButton("Fire1")){            print("pressed Fire1");        }

Getbutton obtains the Virtual Axis name.

Can be used to detect the occurrence of a single keyboard event, such as shooting

 

4. mouse events

Detection click event:

If (input. getmousebuttondown (0) {print ("Left click pressed ");}

0-left, 1-right, 2-middle

 

Long-pressed event detection:

If (input. getmousebutton (0) {print ("Left click pressed ");}

 

Release detection buttons:

If (input. getmousebuttonup (0) {print ("left button opened ");}

 

In the GUI system, double-click detection as follows

Void ongui () {event E = event. current; If (E. ismouse & (E. clickcount = 2) {debug. log ("double-clicked mouse ");}}

, Mainly using the GUI event mechanism.

 

OK.
