Lua Programming Help Thread

HaxxBlaster - Bad bad function seeing as how it is 4 questions specific...

Why not expand your knowledge and that function to allow user input for how many questions via an array, then a optional parameters that match that of the arrays?

Come on now... Stretch your brain past that of the easy way...

You don't have to tell me, i definitely know this.
It's just a very basic way of how to return one of the 4 random strings. But yes, very messy.

i have a qestion how do i get the xmb clock

Whenever I try to run this script on my psp I get an error saying no lua script.
I uploaded it so someone could look at it and find out why it is not working. Right now it is a very simple game and it shoukd have a moveable player and a loading screen. The reason it is so big is because I am working on making a tileengine and I need a lot of tiles and alot of sprites.

I flipped through the script, and what I noticed is you loaded about 190+ images, and you can reduce by using a for loop. All of those lines could be reduced.

Code:

---

linkswordstrikeu = {} --Make your image into a table
for a = 1, 6 do
linkswordstrikeu[a] = Image.load("sprites/link/linkswordstrikeu" ..a..".EXTENSION OF IMAGE")
end

---

Easily do that with all the other images, and you could make ALL of that into very little. For example, you loaded tiles upto 178, you could do that like this:

Code:

---

tile = {} --Make your image into a table
for b = 1, 178 do
tile[b] = Image.load("tiles/tile" ..b..".png")
end

---

Just reduced that whole chunk of code into 4 lines. Just saying, and the script error, I don't know. Unless you put System.usbActiviate, (something like that) and put it in the beginning of your code, and you tried it with a 2.00+ PSP, it wouldn't work.

So your saying there is nothing wrong with my script but I can reduce the size of it.

I did not say there is nothing wrong with your script. And I quote:

I said I did not know but then said about System.usbActivate. I remember somebody saying that that would not work on 2.00+ PSP's.

Obviously something is wrong with your script if it is not running properly.
Try to name it script.lua instead of index.lua.

I fixed the problem.
the problem was

screen:clear()

was like this

screen:clear:()

EDIT
I am trying to insert a new font into my game but I can't get it to work.
Here is the code

Code:

---

font = Font.load("font.ttf")

image:fontPrint(font, 194, 136, Loading: 0%, [color = white])
screen.flip()

---

I found this in the code section of the PSP-Programming website:

Code:

---


nil image:fontPrint(font, x, y, text, [color = black])

---

When it says image:fontPrint, I think it wants the variable name of a user specified image or just screen to print it on the screen image (the screen image always exists. Such as in screen:clear(), screen:blit(x,y,image source), etc.).

OK this function takes up about 300 lines, but this is basically it except for changes in X and Y values and such

I basically just made this function as a dummy..




At first i got the error "attempt to index global 'dummybb'" So i made a table for dummy

dummybb = {blow = 1, go = false}
dummybb[1] = { x = 0, y = 40, go = true}
dummybb[2] = { x = 0, y = 50, go = true}
dummybb[3] = { x = 0, y = 60, go = true}


ok.. so now

I added

check(circle)
check(cross)
check(triangle)
check(square)

in my loop, but they bombs dont blow up when they hit the building. Any help?

Code:

---

function check(dummy)
if dummybb[1].x + 49 >= house1x and dummybb[1].x + 49 <= house1x + 21 and dummybb[1].y + 20 >= house1y and dummybb[1].y <= house1y + 20 and tile1show1a == 1 then
dummybb[1].go = false
tile1show1a = 2
end
if tile1show1a >= 2 then
screen:fillRect(house1x, house1y, 21, 21, blue)
screen:blit(house1x, house1y, house1R)
end
