I would like to execute my program by function. How do I move on to the next function without using wait key?

Here is a copy of my code:

+ Code Snippet

sync on:sync rate 40

MainMenu()
Background()
character()
boxes()

FUNCTION MainMenu()
LOAD SOUND \"rage theme.wav\", 5
PLAY SOUND 5
HIDE MOUSE
LOAD IMAGE \"title.png\", 3
SPRITE 3, 10, 300, 3
FOR thrust=1 TO 24
MOVE SPRITE 3, thrust
WAIT 20
NEXT thrust
ENDFUNCTION

FUNCTION Background()
PAUSE SOUND 5
LOAD IMAGE \"background.bmp\", 1
SPRITE 1, 0, 0, 1
ENDFUNCTION

FUNCTION character()
do
LOAD IMAGE \"game spriteII.png\", 2
SPRITE 2, x#, y#, 2
if rightkey() then x# = x# + 3
if leftkey() then x# = x# - 3
if upkey() then y# = y# - 3
if downkey() then y# = y# + 3
sync
loop
ENDFUNCTION

FUNCTION boxes()
LOAD IMAGE \"box.png\", 4
SPRITE 4, 300, 380, 4
ENDFUNCTION

END

I would deeply appreciate any advice on this issue.

My advice: Discard everything you have.

Follow this:
http://forum.thegamecreators.com/?m=forum_view&t=137027&b=7
And this: http://forum.thegamecreators.com/?m=forum_view&t=115633&b=7
You can find some really cool stuff here: http://dbcodecorner.com/index.php?page=challenge&sort=startdate&order=DESC&p=8
Many people here have Hands on DBPRO book.I heard it's a good one.

When you have the base, start over.Learn how to walk before you start runing.

I can rewrite everything for you, or someone else could do it instead, but i doubt you will learn much from this.After 10 minutes you probably will hit another wall.

Before i had the confidence(and knowledge) to write a game i played with Code Snippets for a really long time.Then i make a game, it was simple,buggy one.Then i make another game...it was simple,buggy one.Then i make another one, no more bugs, but really simple one.Now i am making something challenging.I plan to make something big one day, but i won't fool myself, this might never happen.

To everyone w/ this issue:

I will be posting my success, as I carry on.

I am using hands on dbpro(hob) I and hob II.

Again, Thanks for the input.

If this is what hands on dbpro is teaching i'm glad that never read it.

Just a quick tip:
Learn about indentation! It makes the code much easier to read, not just for you but for everyone who might help you!
For example, this:

+ Code Snippet

FUNCTION MainMenu()
LOAD SOUND \"rage theme.wav\", 5
PLAY SOUND 5
HIDE MOUSE
LOAD IMAGE \"title.png\", 3
SPRITE 3, 10, 300, 3
FOR thrust=1 TO 24
MOVE SPRITE 3, thrust
WAIT 20
NEXT thrust
ENDFUNCTION

is much harder to read than this:

+ Code Snippet

function MainMenu()
    //Load stuff
    load sound \"rage theme.wav\", 5
    play sound 5
    hide mouse
    load image \"title.png\", 3
    sprite 3, 10, 300, 3
    //Move sprite across screen
    for thrust=1 to 24
        move sprite 3, thrust
        wait 20
    next thrust
endfunction

(Lower/uppercase doesn't matter but I prefer lower

)

Keep at it!

Same as Broken_Code said.
I was gonna point that out in my first post but i did not, because it was gonna be too much criticism to the new guy.

So this is what I did, and my code is a step closer to SUCCESS!

+ Code Snippet

sync on:sync rate 60
sync
HIDE MOUSE
LOAD SOUND "rage theme.wav", 5
LOAD IMAGE "background.bmp", 1
LOAD IMAGE "game spriteII.png", 2
LOAD IMAGE "title.png", 3
LOAD IMAGE "box.png", 4

REPEAT
INPUT "Enter section of game (1-4)", no
SELECT no
CASE 1
MainMenu()
ENDCASE
CASE 2
Background()
ENDCASE
CASE 3
character()
ENDCASE
CASE 4
boxes()
ENDCASE
ENDSELECT
UNTIL no = 5

FUNCTION MainMenu()
sync
SPRITE 3, 10, 300, 3
FOR thrust=1 TO 24
MOVE SPRITE 3, thrust
NEXT thrust
PLAY SOUND 5
ENDFUNCTION

FUNCTION Background()
SPRITE 1, 0, 0, 1
ENDFUNCTION

FUNCTION character()
REPEAT
SPRITE 2, x#, y#, 2
OFFSET SPRITE 2, 0, -272
if rightkey() then x# = x# + 3
if leftkey() then x# = x# - 3
if upkey() then y# = y# - 3
if downkey() then y# = y# + 3
sync
UNTIL INKEY$()= "p"
ENDFUNCTION

FUNCTION boxes()
SPRITE 4, 300, 380, 4
ENDFUNCTION
END

!!Saluda guey!!

You'll get an error when you press 5 with that code. (Function declaration found or something like that.)
Please add an End after the Until No = 5 and you'll be fine.

Coding rules for DBPro.

1. ONLY use Do/loop for your main loop, all the other loops are not
optimized to be used as a MAIN loop.

2. Absolutely no Function declarations before your Main DO/Loop.
This is a big error in your first code snippet.

3. There should only be Function calls before the DO/Loop, no loose code.

4. The Main loop should only have function calls, no loose code.

5. Learn to indent your code.

These five steps will make the code easier to read and debug.
Writing code is easy and fast, debugging takes a lot longer.

P.S. Using the "END" command after the Main Loop is deprecated.

*shocked* m-m-maybe it is okay book? I've never read it too though.

Dear Video Game Based! Your code is awful. That is not how functions should be used. That is not how everything should be used! You need to study basic code snippets and learn to make a proper structure. Code is your health and ammo, but structure is your map! You will die in the first dungeon without a map.

P.S. We've all done "hello world" at first, there is nothing wrong in bad code posting for a newbie. Live and learn! Good luck.

Later:

P.S. I recommend you to (buy) start with a Dark Basic Classic, because there are several very-very good micro-games as examples! They are fun and code is a good way to learn structure!

Micro-games as far as I remember them: goblin laser shooting, tank driving, goblin riding a wave runner.

I originally inquired advice on switching between encapsulations via called keys. For example, the main screen appears with options easy, medium, hard. One would use up and down arrow to switch between options and use global enter key (whichever key set as enter). Then, a key would be used to progress to the next screen, or section of the modular program, object, etc. Another key would be used to move to the previous screen, being the introduction screen(under construction). I think I'm doing pretty fly for a white guy. Sorry for the rant.

Again thanks.
