ok coz i needed file check , i didnt know exactly how to do it so i just used:

blah = io.open("file","r")
if blah then
boo = 1 else boo = 0
end

i tried to use blah:close() but if the file didnt exist, i got error...

do this:
if io.open("file", "r") then
...do stuff...
io.close("file")
else
...print("file does not exist")
end

[myschoo]

hey that looks good, i will try :)

edit.
works great,thx again ;)

[ro0kie42]

just use:

tests = "\n" .. test1 .. "\n" .. test2

It will return the variable value instead of the string

Thanks! but now how do i read them?

[k0ud]

Try downgrading then upgrading back to your firmware. Unless you have a copy of your flash0 before the problem. I had a problem with IRSHELL as well now when I press 'O' when listening to music my psp crashs after doing the restart psp to vsh.

already tried that...
-= Double Post =-
hmm this is really bad...

i cant try my flashing program since it stoped working...

it works on other psp's

[xpack]

Use my program FileFlasher to see if it works. If not I recomend a downgrade then an upgrade to see if that fixes the problem

[eldiablov]

He's having flash issues and your recommending that he formats his Flash0?

Bad advice. Unless you can diagnose the problem dont be too quick to give out that kind of advice.

[xpack]

Can you at least flash USB mode

[myschoo]

ai3: post your code here, maybe we can test it or fix something ;)

[xpack]

I'll take a look at it if you want also

[ClearTranquil]

I made some animation code for character movement and I made some code for when the character is standing still. I don't know how to get it so that when the player is pressing nothing it will display the character standing still. Could someone help?

I basically want something to set walkflag = true when nothing is being pressed.

dofile("animLib.lua")
background = Image.load("background2.jpg")
cleo = Image.load("cleofacedown.png")
cleowalkdown = ANIM.new(4, "down", "png", "walkdown/")
cleowalkup = ANIM.new(4, "up", "png", "walkup/")
cleowalkleft = ANIM.new(4, "left", "png", "walkleft/")
cleowalkright = ANIM.new(4, "right", "png", "walkright/")
CleoX = 100
CleoY = 100
walkflag = true
cleodown = true

--WALKING AND CONTROL ANIMATIONS--
while true do
pad=Controls.read()
screen:blit(0,0,background)

	if pad:down() then
	walkflag = false
	CleoY = (CleoY + 4)
	cleowalkdown:blit(CleoX,CleoY,100)
	cleodown = true
	cleoup = false
	cleoright = false
	cleoleft = false
	end

	if pad:up() then
	walkflag = false
	CleoY = (CleoY - 4)
	cleowalkup:blit(CleoX,CleoY,100)
	cleodown = false
	cleoup = true
	cleoright = false
	cleoleft = false
	end

	if pad:left() then
	walkflag = false
	CleoX = (CleoX - 4)
	cleowalkleft:blit(CleoX,CleoY,100)
	cleodown = false
	cleoup = false
	cleoright = false
	cleoleft = true
	end

	if pad:right() then
	walkflag = false
	CleoX = (CleoX + 4)
	cleowalkright:blit(CleoX,CleoY,100)
	cleodown = false
	cleoup = false
	cleoright = true
	cleoleft = false
	end

--RESET FACE POSITION--
if walkflag then
	if cleodown then
	cleo = Image.load("cleofacedown.png")
	screen:blit(CleoX,CleoY,cleo)
	end

	if cleoleft then
	cleo = Image.load("cleofaceleft.png")
	screen:blit(CleoX,CleoY,cleo)
	end

	if cleoright then
	cleo = Image.load("cleofaceright.png")
	screen:blit(CleoX,CleoY,cleo)
	end

	if cleoup then
	cleo = Image.load("cleofaceup.png")
	screen:blit(CleoX,CleoY,cleo)
	end
end

screen.flip()
screen.waitVblankStart()
end

[Merick]

try this:

if not pad:right() and not pad:left() and not pad:up() and not pad:down() then
     walkflag = true
end

one thing, in the "reset face position" section, instead of re-loading images each time you stop after changing direction it would be better to load all four images at the start of your program and put them into a table like this:

cleo = {}
cleo[1] = Image.load("cleofacedown.png")
cleo[2] = Image.load("cleofaceleft.png")
cleo[3] = Image.load("cleofaceright.png")
cleo[4] = Image.load("cleofaceup.png")
end

then, in "reset face position" you could do this:

if walkflag then

	if cleodown then direction = 1 end
	if cleoleft then direction = 2 end
	if cleoright then direction = 3	end
	if cleoup then direction = 4 end

	screen:blit(CleoX,CleoY,cleo[direction])
end

[ClearTranquil]

PERFECT!

Thank you SO much.

[eldiablov]

next time. Use animlib

[Grimfate126]

remember, states dont automatically reset themselves. ;) dont forget to set a state to false, if its not true anymore. and also, you should use else and elseif's a lot more. it gives you many more extra CPU cycles. you whole code can be made much better just by adding elseif's:

dofile("animLib.lua")
background = Image.load("background2.jpg")
cleo = Image.load("cleofacedown.png")
cleowalkdown = ANIM.new(4, "down", "png", "walkdown/")
cleowalkup = ANIM.new(4, "up", "png", "walkup/")
cleowalkleft = ANIM.new(4, "left", "png", "walkleft/")
cleowalkright = ANIM.new(4, "right", "png", "walkright/")
CleoX = 100
CleoY = 100
walkflag = true
cleodown = true

--WALKING AND CONTROL ANIMATIONS--
while true do
pad=Controls.read()
screen:blit(0,0,background)

	if pad:down() then
	walkflag = false
	CleoY = (CleoY + 4)
	cleowalkdown:blit(CleoX,CleoY,100)
	cleodown = true
	cleoup = false
	cleoright = false
	cleoleft = false
	elseif pad:up() then
	walkflag = false
	CleoY = (CleoY - 4)
	cleowalkup:blit(CleoX,CleoY,100)
	cleodown = false
	cleoup = true
	cleoright = false
	cleoleft = false
	end

	if pad:left() then
	walkflag = false
	CleoX = (CleoX - 4)
	cleowalkleft:blit(CleoX,CleoY,100)
	cleodown = false
	cleoup = false
	cleoright = false
	cleoleft = true
	elseif pad:right() then
	walkflag = false
	CleoX = (CleoX + 4)
	cleowalkright:blit(CleoX,CleoY,100)
	cleodown = false
	cleoup = false
	cleoright = true
	cleoleft = false
	end

	if not pad:right() and not pad:left() and not pad:up() and not pad:down() then
	     walkflag = true
	end

next time. Use animlib

he is already using it.

[ClearTranquil]

Mmhmm, I see what you mean Grim. Thank you.

@Merick: Tables you say? I think I'll give it a go. Thanks.

[Yongobongo]

Ok this is really annoying me. Can someone tell me why "w+" mode is not working on luaplayer 0.20?!?! Is there an alternative way to overwrite all existing data in the text file? This is what i wrote, and when i try to write to it i get 'attempt to call file10 - a nil value'

file10 = io.open("data/load.img","w+")

[ClearTranquil]

I'm getting a type error I don't understand:

if cleodown then
	if (MobX - 10 >= CleoX >= MobX + 10) and (MobY - 10 >= CleoY >= MobY + 10) then
		screen:blit(-100,-100,monster)
	end
end

I'm trying to get it so that when you hit the attack button while facing down it will count the attack as taking place if you are pretty much within 10 pixels of the object...

I get the error "Trying to compare number with boolean" for the second line...but MobX is 150 and MobY is 100 and Cleo X and Y are also numbers...

[yaustar]

You must of changed the values of the co-ordinates to a boolean (true/false) somewhere else in the code. Re-check the rest of the code.

[ClearTranquil]

it works on other psp's

worked on my psp few days ago...

I didnt edit anything since it worked....
but now it wont work...

[pspfreak9]

Looks to me like youve got a extra 'end' at the end. I dont know if thats true I just went through it really fast.

[ClearTranquil]

If you scroll up you'll see my code...but...I also just noticed something:

I tried replacing all the variables in that line with numbers so the line makes sense but it keeps giving me the same error anyways...and I've tried with and without brackets.

--ATTACKDAMAGE--

if 140 <= CleoX <= 160 and 190 <= CleoY <= 210 then
	MobX = -100
	MobY = -100
end

The error is: Attempt to compare boolean with number.

And the line it is listed under is the blank space between --Attack damage-- and the if statement.

[Merick]

try this:

if MobX - 10 <= CleoX and CleoX <= MobX + 10 and MobY - 10 <= CleoY and CleoY <= MobY + 10 then

also, you need another "end" at the end of this block

--ATTACKING--
if pad:cross() then

	if cleodown then direction = 5 end
	if cleoleft then direction = 6 end
	if cleoright then direction = 7 end
	if cleoup then direction = 8 end

First of all you have fuctions that you didn't even say what they do from the begining. Like chaseplayer(Urameshi)

[Urameshi]

Urameshi chases the Player, but it wont animate the chasing so its like he's moving towards Player but he's not technically moving, he's standing

[pspfreak9]

Thats not the point, you never said what chaseplayer does you have to have a function like:

function chaseplayer(playername)
anim(playername)--I just made that up but you get the point.
end

[Urameshi]

i already have a chasePlayer function though, do i make another?

[ClearTranquil]

try this:

if MobX - 10 <= CleoX and CleoX <= MobX + 10 and MobY - 10 <= CleoY and CleoY <= MobY + 10 then

also, you need another "end" at the end of this block

--ATTACKING--
if pad:cross() then

	if cleodown then direction = 5 end
	if cleoleft then direction = 6 end
	if cleoright then direction = 7 end
	if cleoup then direction = 8 end

	screen:blit(CleoX,CleoY,cleo[direction])

Works like a charm thank you again for your help. I understand now that I can't check if a variable is between something the traditional way because after the first two steps it'll be either "True" or "False" and True >= 160 makes no sense.
