No worries, eltimo... this should be a pretty easy fix :)

Your problem here is that your "player" variable hasn't been declared. The VergeC compiler hasn't been told what you're talking about, so it gets confused.

To declare a variable, then, you just need to let Verge know what you want to call it, and what you'll be storing in it. In this case, you want the variable to be called "player", and you want it to store a number.

So you tell the compiler this:

   int player;

Now, you can put this inside of MapInit... but once you've left MapInit, your player variable will disappear! Just in case you want to access the player entity somewhere else, you'll want to make it "global". This means that all through your program, you'll be able to access your player variable.

To make it global, just put that declaring statement up above outside of any of your functions. A good place to declare global variables is at the beginning of the file.


Hope this helps! If I was confusing, just ask for clarification and I'll try to provide it.

Thnx dude! i hope that works

Ok, this new error of yours is not attributed to the particular piece of code you've posted here.

Use what VERE's debugger has told you as a starting point: it's not just horrible jargon, it's trying it's best to give you some pointers. Firstly, find the line where you use the function SetAppName(). There's probably an error around this line that's causing VERGE some grief.

More than likely it's (surprise) a missing brace (one of those "{" things) or perhaps you didn't end a line with a ";" when you should have, or put one too may brackets in somewhere. Have a look around your code.

If you can't find it, post the block of code you use the SetAppName() function in and someone will probably be able to spot it.

A variable is a programming convention used to store a value at a location in data. An integer is any whole number.

You're right, we don't explain the fundamentals of programming in the tutorial, so reading our tutorial won't help you there.

But no one is going to be able to teach you how to program from scratch with these forum posts. Or, it is possible, but it could be a tedious experience.

I don't really know how to introduce someone to the concept of a "variable" and an "integer". I mean...one stores data, and the other is a specific type of number data. I recall it was difficult for me at first, but eventually at some point it just "clicked."

Have you ever tried programming in BASIC, or borrowed your grandfather's old Atari? I know, fat chance, but that's one way. Those languages are very simple and good for introducing you to how languages work in general.

There are many resources on the web, I'm sure, for young and budding programmers. And you don't have to be a professional here: all you want to know is how a variable works and what an integer is. That should be easy to find out; not much comes to mind at the moment, but www.wikipedia.org may have something.

Maybe a new article on the basics of programming; like walking you by the idea of using a variable...that might be useful. I'm not sure if anyone's already done it though, to be honest.

What could be especially effective is if you work along with the Verge tutorials as you study C syntax -- assuming you were to try to do so.

For example, Zip has an excellent "Hello World!" collection of programming tutorials for Verge -- it would be effective to support your VC work as you study basic programming.

Hi. i've had a awsome idea. cud we encrporate j2me programming into the verge programming so as to be able to play the games on our mobiles? cus that wud be awsome

Java 2 mobile environment?

Okay. Lines which are comments to yourself need to begin in a ' // '

Example:
// This is my tutorial VC

Next, I'm not sure what that "startup script" line is doing. It may just be a comment or command that I'm not familar with, but I think that setting the first script to be executed needs to be done in maped, not added via the .VC file.

FYI, you shouldn't need anything in tutorial.VC It looks more like your system.VC file. Here are two sample, very basic .VC files that, Unless I've missed something, should let you wander around tutorial.map as Darin.

Finally, could you please do me a HUGE favour and put a wee bit more effort into your spelling? It's always worrying when someone asks for programming help and has spelling like that, because you can never tell if the errors they're getting might just be because of a mispelled line :)



// SYSTEM.VC

int plr, plrx, plry; // GLOBAL VARIABLES

void AutoExec()
{
SetAppName("rosh is the best");
Map("tutorial.map");
}

// TUTORIAL.VC
// Load up tutorial.map in Maped and use the map
// properties dialogue to choose mapinit as the
// starting function

void MapInit()
{
plr = EntitySpawn( 5, 5, "darin.chr");
}

never mind guys because i got it up and running with a little help from my freinds eltimo & jigdafrod but my problem now is that when the game starts the game comes up but i have no characters there to move with please help actually leave it two days for me to look at the pdf and i'll come back.
thancks you guys rule!!!!!!
:)

Some crucial advice, I think: download as many games from the V3 file archive as you possibly can. Most come with their source code and playing them (yes, play them! No sense in not having some fun while you're at it..) and then opening up and browsing through their VC script is one of the best ways of seeing first hand how each line of code has a direct effect on the game.

Try downloading some of our competition entries: they're the simplest to understand because they were all programmed under a strict time limit in most cases.
