Weird problem with strings...

Hi! I am working on a project, which involves the use of strings to allow for future "mods" and easier updating.

I always run into a problem though with strings, heres my code:

function loadLevel(STRING* name);
{
STRING* fullpath = name;
str_cat(fullpath, "\\config.cfg"); // At this line I recieve a "Invalid Arguments in loadLevel" error?
}

function main()
{
loadLevel("map1");
}

Any ideas why this is happening... it seems perfectly acceptable..

Thanks,
Matt.

You cannot equate strings the same way that you can with variables.

Instead to make 2 strings equal you must use:

str_cpy(STRING* name, characters) //the characters are a set of numbers etc enclosed in the "" marks or the name of another string.

for your code you could write:

function loadLevel(STRING* name)
{
STRING* fullpath;
str_cpy(fullpath, name); //this sets fullpath = to the name string
str_cat(fullpath, "\\config.cfg");
}

//rest of your code here

See if that helps

Thanks for the reply!

I've just tried your solution, but now I get two "Invalid arguments" errors!

Could this be a bug?

The string is declared but not initialized. You need the 'str_create' function for that...

Erroneous semicolon after function loadLevel.
"map1" might be an immutable char* const(ant), which might not be passed as a STRING* argument to function loadLevel.

Try this code then:

function loadLevel(STRING* name)
{
STRING* fullpath = "";//this creates an empty string
str_cpy(fullpath, name); //this sets fullpath = to the name string
str_cat(fullpath, "\\config.cfg");
}


Then add in the main

function main()
{
levelLoad("map_name");
}

I have tried this and it should work

Thanks for the replies guys! Got it working now thanks to your solutions . I'll have to remember to try and initialize things if they don't work in the future XD.

Thanks again,
Matt.
