Lua Programming Help Thread

LUAplayer v16
eLoader (newest version)
emenu (newest version)

System.listDirectory() only works when there is just a few files in the directory. Why does having a dozen or so files in a directory that you are listing crash LUA Player? For instance if the root is:

ms0:/PSP/PHOTO/file, I can only have a few pictures in that directory for LUA Player to run correctly.

whats the easiest(less coding) way to do this type of thing,,

<(EDIT// i changed this a bit)>

Player2 wants an apple, another apple, and a banana

If you press X infront of Player2, while you are holding one of those objects, it will display that object beside player2.,, and he no longer needs it,,

but because he wants two apples, how would i code it, so when you give 1 apple, he still wants another one, until you give him another apple,,

you can only give one fruit at a time

Thanks PSPMillonare! :)

Use variables and conditional statements:


if pad:cross() then
if variable_player2apple < 2 then
variable_player2apple = variable_player2apple + 1
screen;print(388, 260, "Thanks for the apple. I now have a total of " .. variable_player2apple .. " apples!", textcol)
if variable_player2apple < 2 then
screen;print(388, 260, "I can accept " .. (2 - variable_player2apple) .. " more apples!", textcol)
else
screen;print(388, 260, "I won't be needing any more apples...", textcol)
end
else
screen;print(388, 260, "Hey, I already have 2 apples and that's enough!", textcol)
end
end

As long as Player2 has less than 2 apples, you will give him 1 more when you talk to him.

that would work if apples was constant,, but in the game im working on, sometimes itll be an orange, sometimes a watermelon,
and you dont know how many there will be,,
could be
orange, banana, apple,
banana, apple, banana,,
its completly random,,

if you need more info to help me on this, just pm me
(btw, its not fruits in my game, i just used it as an example)

EDIT. nvm, ive fixed my problems,, thanks though



and to ZeroX, try this

Code:

---

while true do
screen:clear()
pad = Controls.read()
screen:blit(0,0,Table)


if pad:start() then
Pause = 1
end

if Pause == 1 then
screen:blit(0,0,PauseMenu)
end


screen.waitVblankStart()
screen:flip()
end

you can try making a 'start' function. like:

Code:

---

function start()

pause = true
white = Color.new(255,255,255)

while true do

screen:clear()
pad = Controls.read()

if pad:start() then
pause = false
end

if pause == false then
break
end

screen:blit(0,0,PauseMenu)
screen.flip()
screen.waitVblankStart()
end
end

---

and in your main "while true do" loop, put something that will call this function.

example:

Code:

---

(codes)
if pad:start() then
start()
end
(codes)
