[EminentJonFrost]

His name is VAVA now ;) .
And he isn't leaving lol.

What game you making?

is that directed at me?

[c5cha7]

is that directed at me?

Yes, it was :) .

[EminentJonFrost]

Yes, it was :) .

umm...i dont want to say (at least not publicly).
my partner may not want to.
and honestly, i dont want to say.

[Gutya]

How do i got about taking info from a text file? Such as variables etc. For a config file.

[HaxxBlaster]

Please help me out guys!

Everytime i turn of my psp while i am in my program, and then turn it on, it says that a variable is a nil value, it shoulden't be that way and i can't se why it should behave like it do.

I have seen this problem before but don't remember how i solved it.
I have checked so the variable is the exactly same in all the places.

This is the only problem i have, everything works perfect otherwise!

How do i got about taking info from a text file? Such as variables etc. For a config file.

Like a dofile?
Example:

dofile("txt.txt")

Or what about

file = io.open("txt.txt", "r")
if file then
text = file5:read("*a")
file:close()
end

[Gutya]

file = io.open("txt.txt", "r")
if file then
text = file5:read("*a")
file:close()
end

Could you explain this please? Like what each part does?

You can't turn off your PSP during a LUA game then turn it back on and cary on.

Theres a good tutorial here:
http://www.evilmana.com/tutorials/lua_tutorial_09.php
This will do a whole good for you ;) .
Its better than getting a 10 second mockup from me,
and it use's other strategies too.

[HaxxBlaster]

Gutya
That's just pure bull****!

I have done it atleast a thousand times before with my own programs.

Well ive never heard of that, are you talking about LUA?

[c5cha7]

Oh thanks, forgot about that tutorial.

If your stuck PM me :) .
I Will try my best to help you asap.

[HaxxBlaster]

Gutya

Yes of course, if you noticed, this is the "Lua Help Thread".

[Gutya]

I was just asking, because ive never known of variables staying after youve switched off your PSP.

[HaxxBlaster]

Do you allways gets errors about that everytime you turn on the psp while it have been turned off?

[Gutya]

I'm almost positive that unless you write the variables to another file they will be cleared.

[HaxxBlaster]

I don't mean "Restart" the PSP, read what i am writing.

[Gutya]

Your saying 'Turn off' the PSP.

[HaxxBlaster]

Yes i did, what should i otherwise call it?
I mean the "turn off" that saves the current memory to the PSP.

Don't you find it strange that it don't find a variable that is working perfectly, then it just says it's a nil value.

[Electro]

do you mean 'sleep mode'?

[HaxxBlaster]

Yes i mean sleepmode, i totally forgot that.

Do you know how to solve my problem?
I have got that error some times before, but i don't know how i solved them.

[montrob]

Are you using a sound file that doesnt exist? Isnt a Mono wav? or is a unusable sound file(in LUA). Is the extension of the file there when you load it? Or did you mispell the filename or the variable name when "Soundlay()"ing.
Those are some of th reasons for it, check through and tell me if it works.

[natan333]

guys, is there a button in luaplayer windows to have the same function of the buttons for the psp ? becuase this eloader 97 keep crashing with my 2.0 and i dont like the idea to downgrade though.

>.< i found the controls , but it dosent have the nub controll
:Cry:

[Grimfate126]

hi, i have a prob with my code. here it ispart of it)

math.randomseed(os.time())

a = 0
b = 0
c = 1
d = 1
e = 1
x = 1
y = 120
x32 = x+50
y32 = y+50


x2 = math.random(1000)
y2 = math.random(240)

spike = {}

for c = 1,10 do
spike[c] = { a = math.random(100), b = math.random(100), x232 = x2+a, y232 = y2+b, pic = Image.createEmpty(a, b) } 
end

and i get this error:

error: test.lua:32: Invalid Size

??? how di i fix this?? thx for all your help!!

i havent used a single sound in my program lol

[Grimfate126]

i have another problem(yay), but i solved my other one. my currnet problem:

my collision detection wont work. here is my code:

math.randomseed(os.time())

a = 0
b = 0
c = 1
d = 1
e = 1
f = 1
g = 1
h = 1


x = 1
y = 120
x32 = x+50
y32 = y+50

spike = {}

for c = 1,10 do
x2 = 0
y2 = 0
spike[c] = { a = math.random(100), b = math.random(100), x2 = math.random(2000), y2 = math.random(240), x232 = x2+a, y232 = y2+b} 
end

for h = 1,10 do

if (((x32 >= spike[h].x2) and (x <= spike[h].x232)) and ((y32 >= spike[h].y2) and (y <= spike[h].y232))) then
gameover = true
end

end

if gameover == true then
break

i have defined everything. but the objects pass right through the player..

pls help me..

[natan333]

i have defined everything. but the objects pass right through the player..

pls help me..

i think you have to do something like this

if letterPosy < 2 then letterPosy = 2 end
if letterPosy > 269 then letterPosy = 269 end
if letterPosx < 2 then letterPosx = 2 end
if letterPosx > 477 then letterPosx = 477 end

same as a arrow or an object to stop at a location, but have no idea to make it disapear after it stops

anyways
guys I have a background set up and I draw like a filled red square above it.
I want to erease half of the filled red square with an arreaser picture so one of the half of the square will be red and the other part will replease the backgroung.
not like to erease with a white color, but using the background to errease something and to look the same after erased

is it possible to do it ?
