BitBlt Game

Hi,

There is a little bit of flikering in my game.. need to improve it.. any suggestions...

Sorry once again, the file size is 134kb exe and 128kb source..

I will put it at my web site...

sorry for the inconvience

Thanks,

I think you should combine all timers into one...

If some of the stuff is drawn slower than something else, eventually it will not be drawn for one frame which will make it flicker...

When putting all into one timer the timer wont tick until everything in it is done...That will make it draw everything smooth!

Hope this helps! :)

Btw., you're getting really good at making games :)

Ha ha ha.. I am jobless in the office.. as a result....


The game doesnt have timers...
what i have done is...

VB Code:

Private Sub Form_Load()
Dim tmp As Long, t As Long, coun As Integer
    Me.Show
    mainPic.SetFocus
    While Not gmloop
        t = GetTickCount - tmp
        If t > 1000 Then Me.Caption = "Attack - FPS : " & coun: coun = 0: tmp = GetTickCount
        MoveAll
        DrawAll
        Chk4IndianArround
        ChkCollision
        DoEvents
        DoEvents
        coun = coun + 1
    Wend
    
End Sub
 
 
Public Sub MoveAll()
    Dim i As Integer
    Static tmp As Long
    If GetTickCount - tmp > 120 Then
    tmp = GetTickCount
    
    For i = 0 To UBound(USol)
        USol(i).MoveMe
    Next
        Ind.MoveMe
    End If
End Sub
Public Sub DrawAll()
    Dim i As Integer
    Static tmp As Long
    Dim won As Long
    Ind.DrawMe frmMain.mainPic
    For i = 0 To UBound(USol)
        USol(i).DrawMe frmMain.mainPic
    Next
      
    
    If GetTickCount - tmp > 120 Then
        frmMain.mainPic.Cls
        tmp = GetTickCount
        frmMain.writelog
        Ind.NextStep
        For i = 0 To UBound(USol)
            USol(i).NextStep
            won = won + USol(i).Life
        Next
        
    End If
    If won = -2 - 2 * UBound(USol) Then _
        frmMain.mainPic.Print "You Have destroyed all the enemies": _
        frmMain.mainPic.Print "You are victorious"
        
End Sub

The above is a part of the code... you may have a look at the whole code in my website..

Suggest me some good ideas..

By the way i thought the same idea could be adopted in 3d instead of animating a 3d object i will load say 6 such objects and during runtime i will draw one after another .. Would be very easy and faster as there is no need of any calculations..
Will consume a little bit more memory.. But I am running my OS on P4 512 MB Ram so should not matter..

Thanks,

First of all Thank you..

I have taken up your suggestion and made a small change in my code.. as a result I am getting an FPS of 5000... It was a great increase.. preveiously i was getting 400 FPS, that means about 12 times more speed...

VB Code:

Public Sub DrawAll()
    Dim i As Integer
    Static tmp As Long
    Dim won As Long
    
    Ind.DrawBullets frmMain.mainPic
    For i = 0 To UBound(USol)
        USol(i).DrawBullets frmMain.mainPic
    Next
    
    If GetTickCount - tmp > 120 Then
        frmMain.mainPic.Cls
        
        Ind.DrawMe frmMain.mainPic
        For i = 0 To UBound(USol)
            USol(i).DrawMe frmMain.mainPic
        Next
            
        tmp = GetTickCount
        frmMain.writelog
        Ind.NextStep
        For i = 0 To UBound(USol)
            USol(i).NextStep
            won = won + USol(i).Life
        Next
        
    End If
    If won = -2 - 2 * UBound(USol) Then _
        frmMain.mainPic.Print "You Have destroyed all the enemies": _
        frmMain.mainPic.Print "You are victorious"
        
End Sub

I have modified the draw function... I have made a new public function in the Universal Soldier class which draws the bullets fired by the soldier..

Since i used to draw the soldier every time ,it was creating flickering... Now i am only drawing bullets and soldiers are drawn once in 120 ms hence no flickering...


Thanks,

With timers i was refering to the loop with a temp variable that keeps track of the time...like this one:

VB Code:

If GetTickCount - tmp > 120 Then
    tmp = GetTickCount
    'etc....

there was many of those running at the same time in the game code......so by putting them all together into one timer would fix some problems...
