0,o0 is the top left. x and y are not the width and height and I have no idea what this is trying to do

if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 25 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 29 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x == 30 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x < 40 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 12 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x == 30 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x < 40 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 12 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x < 40 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 12 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x < 40 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 12 then
enemy[1].y = enemy[1].y + 3
end

X represents a position on the X-axis and Y represents a position on the Y axis.

Any help to my question, #4050

[GuitarGod1134]

yah head 54us it should look like this sorry i was mixing my self up with so many different comparison variables i should have just used one didnt know why i had different ones

if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3
if enemy[1].x > 20 then
enemy[1].y = enemy[1].y + 3

and thats my code on making the guy patrol. once i have made him walk as far as i want i will then make him walk backwards by subtracting

[yaustar]

It still is 'wrong' as you are doing the same comparision several times per loop.

dude, why are you donig the same thing ten times?? look on the last page, head_54us has a good example.

It is hard to help you with your problem if you don't state WHAT the problem is in the post.

[AZeyC]

It is hard to help you with your problem if you don't state WHAT the problem is in the post.

I did, the problem is you cannot change the "part" of the password (p1, p2, p3, p4, p5) to the digit you want so you can exit the program:

Lua Programming Help Thread

I also would appreciate it if you could giveme the snippet that allows me to disable the HOME button.

Thanks in advance

[yaustar]

I did a revamp of an existing code snippet a while back: http://forums.evilmana.com/index.php?topic=244.0

You can't disable the HOME button in Lua as it's functionality is in LuaPlayer. So unless you feel like editing the source code of LuaPlayer, you can't.

[AZeyC]

Thanks man, that really helped. And is anyone willing to edit the source for me, I'm getting premium soon. Most likely for christmas so I will donate 1,000 points to you if you did this! :)

[yaustar]

Your error is here:

if "p1" == "p1f" and "p2" == "p2f" and "p3" == "p3f" and "p4" == "p4f" and "p5" == "p5f" then
Something()
end

Why are they in speech marks?

[AZeyC]

I tried removing them and it makes no difference.

But I used your code and now have it the way I want it but when I execute it I get:

ERROR index.lua:75: '=' expected near 'end'

Spoiler for Code:

end

PasswordEntry[CurrentPasswordNumber] = 0
end
end

else
screenrint(TextStart+i*20, 109, PasswordEntry[i], black)
end
end
if password == pf then
os.exit
end
screen.waitVblankStart()
scr
end

I don't have a clue what to do but I have narrowed the error down to the second from last 'end' in the code, this is highlighted.

I also don't understand the line: 'local password = ""' which is also highlighted, what is this line used for?

[yaustar]

os.exit should be os.exit(). Its a function call.

[AZeyC]

I still get the same error and I edited my previous post with another question.
-= Double Post =-
One more question, when making other apps I have encountered errors stating '<eof>', what is this '<eof>'?

[yaustar]

Hmm... looks like some of my code got cut off at the end.

os.exit should be os.exit()
scr should be screen.flip()
local password = "" is to declare a variable of that name in the correct scope for it to be used later.
<eof> is end of file

[AZeyC]

It's works, but here is the code:

System.usbDiskModeActivat e()

red = Color.new(255, 0, 0)
black = Color.new( 0, 0, 0)

file = io.open("password.txt","r ")
PasswordLine = file:lines()
file:close()

PasswordEntry = { 0, 0, 0, 0, 0}

CurrentPasswordNumber = 1

TextGap = 20
TextStart = 174

LastPadState = Controls.read()

while true do
CurrentPadState = Controls.read()

if CurrentPadState:right() and not LastPadState:right()then
CurrentPasswordNumber = CurrentPasswordNumber + 1
if CurrentPasswordNumber > 5 then
CurrentPasswordNumber = 1
end
end

if CurrentPadState:left() and not LastPadState:left() then
CurrentPasswordNumber = CurrentPasswordNumber - 1
if CurrentPasswordNumber < 0 then
CurrentPasswordNumber = 5
end
end

if CurrentPadState:up() and not LastPadState:up() then
PasswordEntry[CurrentPasswordNumber] = PasswordEntry[CurrentPasswordNumber] + 1

if PasswordEntry[CurrentPasswordNumber] > 9 then
PasswordEntry[CurrentPasswordNumber] = 0
end
end

if CurrentPadState:down() and not LastPadState:down() then
PasswordEntry[CurrentPasswordNumber] = PasswordEntry[CurrentPasswordNumber] - 1

if PasswordEntry[CurrentPasswordNumber] < 0 then
PasswordEntry[CurrentPasswordNumber] = 9
end
end

local password = ""

for i=1,table.getn(PasswordEn try) do
password = password .. PasswordEntry[i]
end

LastPadState = CurrentPadState

background = Image.load("background.pn g")
screen:blit(0, 0, background, false)



screenrint(164,89,"Enter your password",red)

for i=1,table.getn(PasswordEn try) do
if i == CurrentPasswordNumber then
screenrint(TextStart+i*20, 109, PasswordEntry[i], red)
else
screenrint(TextStart+i*20, 109, PasswordEntry[i], black)
end
end

if password == PasswordLine then
os.exit()
elseif password == "34903" then
os.exit()
end


screen.waitVblankStart()
screen.flip()
end

I changed the file reading technique, which makes the memory stick flash like crazy, this doesn't work aswell because when I put the code that is in password.txt it doesn't do anything but when I put in the code which is built in it crashes the PSP any idea why?
-=Double Post Merge=-
God, talk about long-winded. I changed back the file reading code and now it still, flashes like crazy but it reads the file properly allowing the input of the code from password.txt to shutdown the psp, which is what I DON'T want. I believe there is something wrong with os.exit(), is this the correct command to exit to the XMB.

One more thing, this code creates several lines in the botom-right-hand corner:

Code for i=0,20 do x0 = i/20*479 y1 = 271-i/20*271 screen:drawLine(x0, 271, 479, y1, green) end

How can I make this draw these lines in the top-left-hand coner?

[yaustar]

for i=0,20 do
x0 = i/20*479
y1 = 279-i/20*271
screen:drawLine(x0, 0, 0, y1, green)
end

-= Double Post =-
Try using break instead of os.exit()/

[AZeyC]

so is break just:

break

or is it:

break()

and how do you draw that line in the top-left hand corner!

[Anti-QuickJay]

System.usbDiskModeActivat  e()

This should be

System.usbDiskModeActivate()

Its a minor error, But its still an error.....

[AZeyC]

That is correct in the code but that is a posting glitch in the forum, and you havn't donated to me yet!

[Anti-QuickJay]

I cant donate, Today, But tommarow, Jake is fixing my account, Even tough i have developer status, I can only do what regular members can do

[AZeyC]

When I changed os.exit() for break, it comes up with an error when the password is input correctly:

ERROR (null)

I don't know what to do!
-= Double Post =-
Could I use the exit() command?

[yaustar]

and how do you draw that line in the top-left hand corner!

I already gave you it.

[AZeyC]

I just release this!

[GuitarGod1134]

dude, why are you donig the same thing ten times?? look on the last page, head_54us has a good example.

but i want him to walk the whole distance i want not just
+1 then -1 that gives my dude no time at all to run past him. what should i do?

[Anti-QuickJay]

It really isnt a protection program....

[yaustar]

but i want him to walk the whole distance i want not just
+1 then -1 that gives my dude no time at all to run past him. what should i do?

Someone didn't understand my code :/ . Use a lower speed if the enemy is moving to fast.

hey ive got the basic engine for my game running but i want it so that when you come out of a house you end up at the front door instead of the middle of the map. I have managed to acheive this mostly. Because when i start inside the house and go outside i end up at the front door but when you start outside and go in then out again you end up in the middle of the map.

hey ive got the basic engine for my game running but i want it so that when you come out of a house you end up at the front door instead of the middle of the map. I have managed to acheive this mostly. Because when i start inside the house and go outside i end up at the front door but when you start outside and go in then out again you end up in the middle of the map.

if (player touches door) then
player.x = (edge of map)
player.y = (edge of map)
end
