Lua Programming Help Thread

[montrob]

sorry for double post, but have a prob.

i tried to do this:

for c = 1, 18 do

desert..c = Image.load("sp/desert"..c..".png")

end

but it says this:

Error: "=" expedcted near ".."

i know its not the image loading part. so what is worng??

I dont know much about the "for" statement.. but try this

for c = 1, 18 do

desert = Image.load("sp/desert"..c..".png")

end

[Grimfate126]

I dont know much about the "for" statement.. but try this

for c = 1, 18 do

desert = Image.load("sp/desert"..c..".png")

end

that wont work cause i want it like this:

desert1 = Image.load("sp/desert1.png")
desert2 = Image.load("sp/desert2.png")
and so on...

BUT when i do that, it doesnt load all the images, in luaplayer PSP, for luaplayer windows, it works awesomely. why?

[TeamOverload]

Thats strange if it works in LuaPlayerWindows it should work in LuaPlayerPSP. What version of LuaPlayer are you using on your PSP? I know LuaPlayerWindows is 0.16. Try having the same version, not sure if that would make a difference though.

[Glynnder]

luaplayerwindows is 0.14

[EminentJonFrost]

that wouldnt work montrob, he wants to load many images in one 'for' loop. by taking out the "..c", you take out what he's using to load multiple images.

[emericaska8r]

what's wrong? what error are you getting?

well when i do it, it clears the image i quess, yet makes the whole screen a greenish color.

[emericaska8r]

btw, my code is on the previous page.

[slicer4ever]

ok well then try this:

playervisible = yes

if playervisible == yes then
screen:blit(0,0,player)
end

that should work

[Glynnder]

who's that playervisible script for?

[emericaska8r]

no that won't help, i want to just clear the image, and not the whole screen thats all i am trying to do. Does anyone know how. Like lets say you display a person, and then when you press x it clears that person, yet everything else stays. Also, if you can do this then like if you used screen:blit to paste grass everywhere, and then blited the person on top of the grass, would the grass be shown underneath once you cleared the person.

[emericaska8r]

also, is there anyone that i can e-mail my code to and see where my bugs are. Its really simple, yet since i am a very begginner in lua, I am not sure what is wrong. Thanks, my E-mail is [email protected] . If you can help me e-mail me or post here.

I hear people saying that this will work:

screen:clear(image name here)

Have you tried it?

It should.

Hi I have a question:

if player1.x >= 100 and player1.x <= 116 and player1.y >= 200 and player1.y <= 216 then
picture = true
end

The code above dosent work but an example.
My question is:
I have a picture "player1" somewhere in the psp screen.
Is it possible to make the picture "player1" to have x and y axis so when "picture1" goes to that place, picture will be true.

You may think of doing

-------picture1 somewhere in the txt
screen:blit(x0, y0, player1)

---

if x0 >= 100 and x0 <= 116 and y0 >= 200 and y0 <= 216 then
pause = true
end

but this i know.
with this code above, not the hole picture1 that if it touches the x and y axis it will be true.

wait, you want it so that if part of the pic is in a specific place it becomes true, or when the whole thing goes into the specific place?

[natan333]

ok. imagen if picture "player1" is big but not 2 big

-------picture1 somewhere in the txt
screen:blit(x0, y0, player1)

---

if x0 >= 100 and x0 <= 116 and y0 >= 200 and y0 <= 216 then
pause = true
end

if the bottom of the big picture "player1" touches the x and y axis to be true, it will not do nothing.
if the topleft of the picture touches the x and y axis, it will turn true

the thing i want to know if its possible for any part of the big "player1"
picture to hit the x, y axis to be true

but hey, picture "player1" is a moving picture

[EminentJonFrost]

I dont believe so...no, not possible.
If you had several images "stringed" together, then yes, it would be possible since all you would need to do is make the small images you want "true"..true. lol

if with picture isnt possible, i think its possible to add a moving invisible square around the picture "player1" so when it hits the x, y axis it will be true.
but i not idea how to make it

[EminentJonFrost]

what do you mean you dont know how to make it? its the same as any other photo.
just be sure that the "player" pic is blitted AFTER the square, and make the square become true when you want it to.

-------picture1 somewhere in the txt
screen:blit(x1, y1, square, false)
--screen:blit(x0, y0, player1) -- Move this...

---

if whatever = whatever then
screen:blit(x1, y1, square, true)
end

--here, right after the square is blitted.
screen:blit(x0, y0, player1)

if x0 >= 100 and x0 <= 116 and y0 >= 200 and y0 <= 216 then
pause = true
end

yeah did kinda the way you said for bunch of pictures
i did with adding dots arround the picture and making them x0+(number), y0+(number) :Jump:
hey is there a invisible color ? so it dosent show up?

um...you could not blit it. :icon_wink

[natan333]

hmm, dont got it

is there a way to make

screen:drawLine(x0, y0+15, x0, y0+15)

with no color ?

[EminentJonFrost]

nope.
curious, why draw am invisible line?

[natan333]

nope.
curious, why draw am invisible line?

well, becuase this picture have an invisible square (if you put in the screen and move arround), and the dots is to put in the top right side, bottom right side and left. top left side dont need becuase picture1 is included with them all x0, and y0 so when it touches the x and y axis in a place i mark, it will change to something.

but hey. i might put a invisible picture with only 1 pixel to do it :icon_wink

[Altair]

hmm, dont got it

is there a way to make

screen:drawLine(x0, y0+15, x0, y0+15)

with no color ?

Yes but you have to draw it to another image then the screen. Then you blit that image to the screen but with alpha set to 255.

So something like this:

invis:drawLine(x0, y0+15, x0, y0+15)
screen:blit(0, 0, invis, 0, 0,invis:width(),invis:height(),true)

[natan333]

guys, is there a software that records every sound, that comes out from the soundbox or headphone?

example:
record a jump sound from a game

[SG57]

yes... i just recorded the streaming Dont Wait from the website now i have the song for free... You can take the sound from: Speakers, Sound Card, Microphone, Web cam, etc.

Its called ReplayMusic. A DEMO version is out.. allows 25 tracks t be recorded, just click start, do the sound from game, then stop recording, then convert or whatever...

P.S. Anyone know what an LG Cingular C1500 Cell Phone's ringtone codec is? I have this converter, just dunno what codec it is in...

[natan333]

hehehe . i got a registration code . but not sure if its registered becuase it crashed

[PSPduh]

I am having trouble with this code. I get the error: index.lua 28 'then' expected near '='. :Argh: :Argh: :Argh: The code:

red = Color.new(255,0,0)
yellow = Color.new(255, 255, 0)
blue = Color.new(0, 0, 255)
orange = Color.new(223, 88, 6)
grey = Color.new(94, 97, 111)
black = Color.new(0, 0, 0)
white = Color.new(255, 255, 255)
green = Color.new(0,255,0)

duh = Timer.new()
duh2 = duh:time()
x = 470
y = 0
duh:start()

man = Image.load("man.png")

while true do
screen:clear(white)

if duh2 >= 470 then
screen:blit(470,0,man)
end

screen:blit(x,y,man)

for i = 1, 470 do
if duh2 = i * 1 then
man.x = man.x + 1
end

screen.waitVblankStart()
screen.flip()
end

The line that is bolded is line 28.

[SG57]

me 2 ;) i bought it ;) now i just need to fix my internet/text messaing on my cell to download my ripped song... after finding what ringtone codec it is in...
