shorten a string ?

I want to retunr a part of my string. How I'm supposed to do that ?

Exemple :

new String:test[32];
Format(test, sizeof(test), "just a test");

And I want to shorten the content of test to "just"

Re: shorten a string ?

They easiest you can do in this case is this.

PHP Code:


		
			
test[4] = '\0';

So, by doing this if I do something like this :

if(test[4] == "test")
PrintToChatAll("Sucess, the value of "test" is %s", test[0]);

it's will work ?

EDIT : Yep, it's work.

Re: shorten a string ?

No, don't do that.
Strings are char arrays, thus the number there is a index of the array which refers to a single char.
You can't compare chars with strings that way, use something like this instead.
Using an string index with PrintTo* is a special case i won't explain here, more info below.
Before you continue, please head over here and read how strings in SourcePawn work.

Re: shorten a string ?

Okay, but now I don't understand. How I can use this ?

PHP Code:


		
			
if(StrEqual(test, "just"))
{
       PrintToChat("Work");
}
else
{
       PrintToChat("Don't work.");
}

It does print : "Don't work," :(

Re: shorten a string ?

Do you know what the string is actually equivalent to? I am going to presume that it is as you stated earlier: "just a test". The native StrEqual is going to check if two strings are 100% equal (use the bool to enable/disable case sensitivity).

So if you define String test like this:

PHP Code:


		
			
new String:sTest[] = { "just a test" };

and then check this:

PHP Code:


		
			
if (StrEqual(sTest, "just"))
{
    LogError("This Worked");
} else
{
    LogError("This Did Not Work");
}

Then it is ALWAYS going to return false, because String:sTest is not "just" but rather "just a test". For that kind of a check you want to do something like this:

PHP Code:


		
			
if (StrContains(sTest, "just") != -1)
{
    LogError("This Worked");
} else
{
    LogError("This Did Not Work");
}

StrContains is a nice native that simply checks if one string is found inside another; if the string is not found, a value of -1 is returned (this is why you specify != -1). Hope this helps you!

No, it's for all natives.

He used PrintToChat in his code, thus i referred to that.
