Brennan's adventure game help topic.

[brennan]

I'd rather not make a topic every time I have a question. So, this will be the permanant help topic for my upcoming text based adventure game.

First:

To use the Jeremysr's keyboard, does the LUA game file have to be in the same directory as all of the keyboard files?

[Jeremysr]

I guess it should work if you put it in a directory called "keyboard" and put at the top of your program:

require( "keyboard/keyboard.inc.lua" )

But I've tried something like that before and it didn't seem to work....maybe you need the CF version?

[brennan]

I'll try.

I just don't want to have to put all the keyboard files in the root.

I have the CF version.

[brennan]

I never thought I'd have to have to have help with this, but I can't get text to display.

Code:

-- set up screens
SCREEN_TOP = 1
BGTopText = Screen.LoadTextBG()
Screen.Initialize( SCREEN_TOP, BGTopText )

-- display start screen
BGTopText:PrintXY (9, 11, "Adventure Game" )
BGTopText:PrintXY (9, 12, "Press any key" )
DSLua.WaitForAnyKey()
BGTopText:Clear()

-- set up keyboard
require( "keyboard.inc.lua" )
require( "functions.inc.lua" )

-- game start
BGTopText: PrintXY (1, 24, "You are in a cave, there is a small candle")
BGTopText: PrintXY (1, 25, "to you left. What do you want to do?")

action = keyboard()
if action == take then
BGBotText:PrintXY (1, 27, "You took the candle!")
end

DSLua.WaitForAnyKey()

Text stops appearing on the top screen after I clear it up at the top (after the start screen)
I'm stumped.

(Also, I'm not sure if my "if" statement works, I haven't tested it.

[Jeremysr]

You're trying to print it at Y position 24, 25, and 27. It only goes from 0 to 23. (But X goes from 0 to 31.)

Also, when comparing things to strings, you put the string inside quotations marks unless it's a variable. So it should be: if action == "take" then

[brennan]

Thanks much, you're the man.

[Jeremysr]

I just finished writing a wordWrap() function. It's in Functions 1.6.

It'll prevent your te
xt from looking like th
is sentence.

[brennan]

Wow, I was just thinking about how how bad the text looks 'cause it's not wrapped.

You're a mindreader.

EDIT: Download link?

[Jeremysr]

It's here: http://www.bio-gaming.com/jeremy/dslua/downloads/functions.zip

This is how you use it:

wordWrap( "The quick brown fox jumped over the lazy dog.", 1, 2, 3, SCREEN_TOP )

The first argument is the text be printed. The next two arguments are the X and Y positions to start printing on. The fourth one ("3" in the example) is the colour code (3 would be blue). And the last one is the screen to print it on, which can be 1 or 0. Also, you need your screen(s) to be called BGTopText or BGBotText for it to work.

[brennan]

I could put that in a function, and make it easier, like:

Code:

wrapText( "Wrapped text" )

Pretty easily, right?

[Jeremysr]

You have to put in all the arguments. I guess I should go to lua.org and learn how to make optional/default arguments but for now you have to put all of them.

Or you can go into functions.inc.lua and change it...

Oh, you mean something like this?

Code:

function wrapEasyText( txt )
       wrapText( txt, 1, 1, 7, SCREEN_TOP )
end

[brennan]

Oh, yeah. I'll do that.

I thought I could

Code:

function wrapText( "(I'm not sure what I'd have to put here)" )
wordWrap( "The quick brown fox...", 1, 1, 7, SCREEN_TOP )

But I guess it would be easier to just change the .inc.lua ...

(We need a DSLua IRC channel for small chitchat like this :p)

[Jeremysr]

Yeah I guess you missed my edited post. I thought you meant something else. And yes an IRC channel would be good.

[brennan]

Oops, yeah, I missed the edit.

EDIT: Just added that function to the .inc.lua file, work just as wanted

can this also be a general help topic where every1's questions can be answered and code can be reviewed?
