Update () and FixedUpdate () are automatically called cyclically during Update in the game.

Update is called every time a new frame is rendered. FixedUpdate is executed at a fixed interval and is not affected by the Frame Rate of the game. It is generally used in steel.

Steel body. If gravity is not checked, move the ball side down:

# Pragma strict

Vartranslate_object: Rigidbody;

FunctionFixedUpdate (){

If (translate_object! = Null ){

Translate_object.rigidbody.transform.position.z + = 0.1;

}

}

Apply a rising force when the ball falls to the end.

# Pragma strict

Import System;

Var translate_object: Rigidbody;

Var li: int = 20;

Function FixedUpdate (){

If (translate_object! = Null ){

If (translate_object.rigidbody.transform.position.y <11 ){

Translate_object.rigidbody.AddForce (0, li, 0 );

}

}

}

1/(1*2) + 1/(2*3) + 1/(3*4) + ...... + 1/(19*20) = use a simple algorithm to write the process

1/1*2 + 1/2*3 + 1/3*4 + 1/4*5 + 1/5*6 ...... 1/19*20
= (1-1/2) + (1/2-1/3) + (1/3-1/4 )... + (1/18-1/19) + (1/19-1/20)
= 1-1/20
= 19/20

Simple Algorithm: 36-28 + 74-72

3.6 + 7.4-(2.8 + 7.2)
= 11-10
= 1
