Unity Penguin Smashing Piggy Note 2

2. Scripts

1) Slingshot script

1-input. Getbutton function Test

　　　　　　Description :

Input. Getbutton ("...") is returned according to the button name true when the corresponding virtual button is pressed

Input. Getbutton ("Fire1"): determine whether to click the mouse or touch the screen

　　　　　Measured:

void Update () {

BOOL Bisbuttondown = Input.getbutton ("Fire1");

if (! Clicked) {

if (Bisbuttondown) {

Print ("tap screen");

}

}

}

　　　　　　Effect:

　　　　　　Results:

function is correct

2-Collider. Raycast () function test

Description

Collider. Raycast (): Returns a Boolean (bool) value that returns true if the ray and any collider intersect ,otherwise false. That is, it returns true when the light touches any collider, otherwise false.

Specific Description:http://www.ceeger.com/Script/Collider/Collider.Raycast.html

measured :

error:"unityengine.component" does not containthe definition of "Raycast" and cannot find an acceptable type of " Unityengine.component"The first parameter of the extension method"Raycast"( whether a using directive or assembly reference ?) D:\Unity\unity01\qiezaxiaozhu\Assets\Scripts\DanGongS.cs

Results:

The function cannot be run in vs2010 , presumably removing the function for Unity 5.x . Find the Substitute function:physics.raycast

3-physics.raycast () function test

Description

Physics.raycast (): ray projection, true when Ray casts intersect with any collider, otherwise false.

Specific Description:http://www.ceeger.com/Script/Physics/Physics.Raycast.html

measurement 1:

1. true if Ray casts intersect with any collider, otherwise false.

void Update () {

BOOL Bisbuttondown = Input.getbutton ("Fire1");

if (! Clicked)

{

if (Bisbuttondown) {

Ray Ray = Camera.main.ScreenPointToRay (input.mouseposition);

Raycasthit RCH;

if (Physics.raycast (ray, out RCH, 1000.0f)) {

Print ("Collision");

}

}

}

}

result 1:

true if Ray casts intersect with any collider, otherwise false. established

Measurement 2:

since this project to lock click Slingshot for the reaction, the requirements and measured 1 does not match, so the use of his overloaded function.

1. Create a new layer for the Slingshot , (edit-project settings-tags ands layers-layers-user Layer 8- "Fasheqi" )

2. modify the layer of the catapult's preset body ,

void Update () {

BOOL Bisbuttondown = Input.getbutton ("Fire1");

if (! Clicked)

{

if (Bisbuttondown) {

Ray Ray = Camera.main.ScreenPointToRay (input.mouseposition);

Raycasthit RCH;

if (Physics.raycast (ray, out RCH, 1000.0f, 1 << 8)) {

Print ("Collision");

}

}

}

}

result 2:

Ray casts are true only when the collider crosses the "fasheqi" layer, and the others are false.
