Hello,
when using the following code the available memory gets reduced heavily and the free memory only knows one direction...
Is there a way to reduce the memoryconsumption?
Code: Select all
Function p_DefMaxPage(total)
maxpage=Int(total/(AreaDim-1))
EndFunction
Function p_pagehandling()
If page >= maxpage
page=maxpage
DisableButton(10)
EnableButton(11)
Undo(#TEXTOBJECT,10)
Else
EnableButton(10)
EndIf
If page = 0
DisableButton(11)
Undo(#TEXTOBJECT,11)
EndIf()
EndFunction
Function p_DisplayNationTab()
CopyBrush(tabbrush,99)
p_DefMaxPage(NationCount)
p_pagehandling()
SelectBrush(99)
SetFontColor(#BLACK)
Local fontsize = GetAttribute(#DISPLAY,0,#ATTRFONTSIZE)
Local y = 0
Locate(0,y)
Print("ID")
Locate(50,y)
Print("Nation")
For i = (page*(AreaDim-1)-page) To ((page+1)*(AreaDim-1))
If (i < NationCount)
y = y + fontsize
Locate(0,y)
Print(t_nation[i][0])
Locate(50,y)
Print(t_nation[i][1])
EndIf()
Next
EndSelect()
DisplayBrush(99,#CENTER,120)
FreeBrush(99)
EndFunction

Well, keep in mind that if layers are enabled, every call to
Print() will insert a new layer. And every layer needs some memory. So you should implement some kind of layer managing mechanism: i.e. make sure that you kill all layers that you no longer need (using
RemoveLayer()).
Hollywood can't do this automatically because it doesn't know when a layer is obsolete. You have to keep track of all your layers on your own.

Is it true even if I use "SelectBrush" when Printing? I ask because I use
Code: Select all
info = GetAttribute(#DISPLAY,0,#ATTRLAYERS)
to get the count of added layers and this returns only one added layer.
Nevertheless removing Layers based on this number helped.

Yeah, this is a bug. Fixed in v4.5. In v4.0 #ATTRLAYERS will only be correct if no SelectXXX() is active.

Good!

By the way, tracking memory usage will be much easier with Hollywood 4.5 because it has a
OpenResourceMonitor() function which opens a resource monitor that shows the number of brushes, anims, layers, bgpics, sounds, etc etc. currently in memory and constantly updates these values. This is very useful for debugging the memory efficiency of your scripts. If your layers constantly get more and more, then your code is bad
