Thanks

Oh okay, thank you that helped.
Menu = Screen.loadImage(System.currentDirectory().."Menu.bmp")
Screen.drawImage(100,127,Menu,TOP_SCREEN)
if Network.isWifiEnabled() then
-- Download a file
Network.downloadFile("RemovedLink","/Downloaded.zip")
-- Extract the file
System.extractZIP("/Downloaded.zip",System.currentDirectory().."/")
-- Delete the temp file
System.deleteFile("/Downloaded.zip")

What do you mean exactly by blending it at 0,0 coordinates
I just tried setting the coordinates to 0,0 and it still gives me these weird pixels when starting LPP and it doesnt do anything, just sits here
Yeah thats my whole source code, okay so I added waitVblankStart and the flip thing and the system.exit but just a black screen even when I press A
Menu = Screen.loadImage(System.currentDirectory().."Menu.bmp")
Screen.flip()
Screen.waitVblankStart()
Screen.drawImage(100,127,Menu,TOP_SCREEN)
if (Controls.check(Controls.read(),KEY_A)) then
if Network.isWifiEnabled() then
Screen.debugPrint(0,0,"Downloading: Please Wait",Color.new(255,255,255),BOTTOM_SCREEN)
-- Download a file
Network.downloadFile("LinkRemoved","/Downloaded.zip")
-- Extract the file
System.extractZIP("/Downloaded.zip",System.currentDirectory().."/")
-- Delete the temp file
System.deleteFile("/Downloaded.zip")
dofile(System.currentDirectory().."news.lua")
end
end
System.exit()
while true do
pad = Controls.read()
if Controls.check(pad,KEY_B) then
System.exit()
end
local newHour, newMin, newSeg= System.getTime()
if not newSeg == oldSeg then
setNewRefresh();
else
Screen.clear(TOP_SCREEN)
end
end
Hi! I'm trying to make System.getTime, getBatteryLife and getDate refresh after changing but I'm unable to do it.
In the while I check if for example getTime has changed and if it change, it refresh the screen but I doesn't work. For example:
Code:while true do pad = Controls.read() if Controls.check(pad,KEY_B) then System.exit() end local newHour, newMin, newSeg= System.getTime() if not newSeg == oldSeg then setNewRefresh(); else Screen.clear(TOP_SCREEN) end end
and as you guest, it only clear the top screen.
Could you help me or explain why this happend? I'm used to use Java and C and this type of programing with whiles make me mad
Thanks for all.
