when i change the variable currentarea should i assign the picture variables used in the previous area to "nil" to save ram space or is it fine???

[myschoo]

i think if u use dofile they will still stay in RAM

[GuitarGod1134]

Im trying not to use dofiles right now both my areas are in 1 file index.lua but I see a lot of posts about people saying the psp crashed because of the ram overload on picture files so i was wondering if i need to assign them to nil or not or if that will even do anything.

[EminentJonFrost]

???

its fine. just do

if currentarea = something then
blit this image
if not then
blit this one

the psp shouldnt get an overload from that..i do it all the time

[Grimfate126]

when i change the variable currentarea should i assign the picture variables used in the previous area to "nil" to save ram space or is it fine???

it depends. is your player allowed to back to that area? if its gone forever, then just make it nil, otherwise keep it.

[GuitarGod1134]

ok thanks alright well i made this little app while i was waiting for some responses and im getting an error something at like 49 with is the eof but idk whats wrong.
edit : lol nvm i never put while true do lol.

I'm having trouble with exiting my menu.

black = Color.new(0,0,0)
red = Color.new(255,0,0)
white = Color.new(255,255,255)
menustatus = 1
stickmenu = Image.load("stickmenu.png")
oldpad = Controls.read()
while true do
pad = Controls.read()
screen:clear(white)
screen:blit(0,0,stickmenu)
screen:print(180,170,"Single Player",black)
screen:print(180,180,"Multiplayer",black)
screen:print(180,190,"Controls",black)
screen:print(180,200,"Exit",black)
if menustatus == 1 then
screen:print(180,170,"Single Player",red)
end
if menustatus == 2 then
screen:print(180,180,"Multiplayer",red)
end
if menustatus == 3 then
screen:print(180,190,"Controls",red)
end
if menustatus == 4 then
screen:print(180,200,"Exit",red)
end
if pad:down() and oldpad:down() ~= pad:down() then
menustatus = menustatus + 1
end
if pad:up() and oldpad:up() ~= pad:up() then
menustatus = menustatus - 1
end
if menustatus == 0 then
menustatus = 4
end
if menustatus == 5 then
menustatus = 1
end
if pad:cross() and menustatus == 1 then
--code--
end
if pad:cross() and menustatus == 2 then
--code--
end
if pad:cross() and menustatus == 3 then
--code--
end
if pad:cross() and menustatus == 4 then
os.exit()
end
screen.waitVblankStart()
screen.flip()
oldpad = pad
end

It waits about 10 seconds and shuts completely off. So it won't go to the XMB like it's supposed to.

[GuitarGod1134]

whats wrong with home? if u want to go to the xmb?

[Urameshi]

i just have a quick question so here it is:

??Why is it when i look at my picture using luaplayer for windows, it flickers??

[GuitarGod1134]

something to do with the loop repeating i guess.

[Urameshi]

is there any way i can fix it?

[Cheez Pirate]

whats wrong with home? if u want to go to the xmb?

Because no one likes the home button. Now can someone help...

[TacticalPenguin]

if pad:cross() then os.exit() end

Doesn't that work?

[Cheez Pirate]

No... I said it freezes and shuts off completely in 10 seconds.

[TacticalPenguin]

Get the custom luaplayer by cools and use System.quit()

[Cheez Pirate]

cant find it. can i get a link?

[TacticalPenguin]

Just search for it, its a couple pages back here in the psp development forum.

[Cheez Pirate]

oh i thought it was on dl.qj.net

search isn't picking it up.

Now i wanna know how to keep my controls menu on the screen when i press X so I don't have to hold X down. So I go to controls on the main menu. I press X and I want it to keep the controls menu up. What it does now is make me hold down the button for it to stay up.

black = Color.new(0,0,0)
red = Color.new(255,0,0)
white = Color.new(255,255,255)
menustatus = 1
stickmenu = Image.load("backgrounds/stickmenu.png")
controlsmenu = Image.load("backgrounds/controlsmenu.png")
oldpad = Controls.read()
while true do
pad = Controls.read()
screen:clear(white)
screen:blit(0,0,stickmenu)
screen:print(180,170,"Single Player",black)
screen:print(180,180,"Multiplayer",black)
screen:print(180,190,"Controls",black)
if menustatus == 1 then
screen:print(180,170,"Single Player",red)
end
if menustatus == 2 then
screen:print(180,180,"Multiplayer",red)
end
if menustatus == 3 then
screen:print(180,190,"Controls",red)
end
if pad:down() and oldpad:down() ~= pad:down() then
menustatus = menustatus + 1
end
if pad:up() and oldpad:up() ~= pad:up() then
menustatus = menustatus - 1
end
if menustatus == 0 then
menustatus = 3
end
if menustatus == 4 then
menustatus = 1
end
if pad:cross() and menustatus == 1 then
dofile("singleplayer.lua")
end
if pad:cross() and menustatus == 2 then
dofile("multiplayer.lua")
end
if pad:cross() and menustatus == 3 then
dofile("controls.lua")
end
if pad:l() and pad:r() then
System.usbDiskModeActivate()
end
screen.waitVblankStart()
screen.flip()
oldpad = pad
end

And the dofile("controls.lua") is

screen:clear(white)
screen:blit(0,0,controlsmenu)

without the quotes of course.

i just have a quick question so here it is:

??Why is it when i look at my picture using luaplayer for windows, it flickers??

...or the code may be inefficient. wrongly place "screen:clear"s, "screen.waitVblankStart"s , and "screen.flip"s can do that.
-= Double Post =-
to Cheez Pirate: i think its doing that because the controls.lua file doesnt have a loop. it just does those two lines of code then quits. unless theres more youre not saying.
