Yi Language's counting loop causes excessive CPU usage

Yi Language’s count cycle CPU usage is too high

If you read it like this, you may read hundreds of hard disks in one second, and more than 10,000 hard disks in one minute! ! !

You can try the following array method, it should be better!

.Version 2

.Support library EdirectX

.Assembly Window Assembly 1

.Assembly variables screen, screen

.Assembly variable page, page, , "0"

.Assembly variable abscissa, integer type, , "0"

.Assembly variable ordinate, integer type, , "0"

.Assembly variable background, page

.Assembly variable record number, integer type

.Subroutine __start window_created

.Local variable n, integer type

Screen.Create full-screen mode (get window handle (), 800, 600, 32, false)

Background = screen.Get background page ()

Open (take the running directory () "\data\map1.edb", , , , , , )

Number of records = Get the number of records ()

Redefine array (page, false, number of records)

Redefine array (abscissa, false, number of records)

Redefine array (ordinate, false, number of records)

Go to the first record ()

.Counting cycle head (number of records, n)

Page [n]. Create a bitmap page (screen, get the running directory () read ("name"), )

Abscissa [n] = Read ("abscissa") ' Logically, if the types in the database correspond, there is no need to convert again

ordinate[n] = read("ordinate")

jump over ()

.Counting loop end ()

closure ()

Clock 1. Clock period=100

.Subroutine _Clock 1_Period Event

.Local variable n, integer type

Clock 1. Clock period = 0' These two sentences can be removed

Background.Fill page (#white)

.Counting cycle head (number of records, n)

Page [n]. Block copy (background, abscissa [n], ordinate [n], )

.Counting loop end ()

Screen.SwapPage(false,false,false)

Clock 1. Clock period = 100' These two sentences can be removed
