Hello!
I am having a hard time understanding

for(new i;i<0;i++)

I know it is suppose to catch all the data 1 by 1 from somewhere, as example

public plugin_precache(){	
	for(new i = 0; i < sizeof(ItemsConst); i++)
		precache_***(ItemConst[i]);
}

Getting all the data from a const and then counting it in the precache function.
But is there a way to make it count 1 by 1, not all the items, but a line check after line check.
Like for example i want to make it like this:

new Const[][]{
	"number 1",
	"number 2",
	"number 3"
}

public plugin_init(){
	register_clcmd("say /count","CountNumbers")
}

public CountNumbers(id){
	for(new i;i<sizeof (Const);i++){
		client_print(id,print_chat,"The number is: %s", Const[i])
	}
}

So when player types /count, instead of ALL items to get printed, i want it first to appear Number 1 and then after he types /count again, Number 2 will apear and etc

Tried to search for answers and what not, but haven't found any, and i got a headache by trying to understand this on my own

You don't need a for loop at all. You need to have a counter for each player that keeps track of which message they should get when they run the command. Here is a simple example:

PHP Code:

new g_iCounter[33] // Stores the counters for each of the players
new g_szStringArray[][] = {"hello", "world"}

public function(id)
{
    // Use the string from the array based on the player's counter
    client_print(id, print_chat, "%s", g_szStringArray[g_iCounter[id]])

    // Increment and wrap the counter for the player
    g_iCounter[id] = ++g_iCounter[id] % sizeof(g_szStringArray)
} 


So, the counter will cycle through each of the indices for g_szStringArray repeatedly as the function gets called. You can have as many strings in g_szStringArray as you want and you won't need to change any other code to have it still work.

Thank you! While it is exactly what i needed, i still have some questions.
First is, what is the use of " % " in

g_iCounter[id] = ++g_iCounter[id] % sizeof(g_szStringArray)

how does that work exactly

And also i'd like to ask if i were to Limit those options, how could i do so?
Example is if i created enum for the array

enum _:contains
{
	Name[32],
	Number
}

new g_szStringArray[][contains] = {"hello" 2}, {"world", 5}

Is there any simplier way than just checking with

new iNumber ++iNumber
 if(iNumber == g_szStringArray[1][Number])
return

for every single option, while if iNumber reaches the limit of

g_szStringArray[x][Number]

only the

(x)

option to stop working, while the remaining continue to appear

Pardon me if im not making much sense,
if needed i would try to make a functional example script to represent my desires.

That's called modulus operator. I'm not an expert on the subject so I'm just going to quote something I found in a webpage

C++ provides the modulus operator, %, that yields the remainder after integer division. The modulus operator can be used only with integer operands. The expression x % y yields the remainder after x is divided by y. Thus, 7 % 4 yields 3 and 17 % 5 yields 2.

The code fysiks provided already does that

sizeof(g_szStringArray)

sizeof as the name suggests returns the size of the specified array.

Thank you for the reply!

the provided code from fysiks works infinitely, without anything to stop a line from the const of working (as i required).

But i also want to see if there's any simplier way than the one i have mentioned above, without having to check if each line has reached the number & then return it in order to get to the next line whom number is not yet reached.

Use the modulu operator which will returns the division remains.

For example 5 % 2 will return 1 since 5 has two twos and remains 1 extra.

i have no previous nor current knowledge of bitsum things or whatever they're called,
so im havin a hard time understading it.
I have made it into a function given the code from fysiks so i'll be grateful if somebody could rewrite it as requested, since i cannot come to understand it on my own.

PHP Code:

#include <amxmodx>

enum _:Items
{
    Name[32],
    Number
}

new g_iCounter[33]        //option 1    //option 2
new g_szStringArray[][Items] ={{"hello", 3}, {"world", 6}}

public plugin_init(){
    set_task (2.0, "PrintMessage", _, _, _, "b")
}

public PrintMessage(id){
    new gCounter
    new x = ++g_iCounter[id] % sizeof(g_szStringArray)
    client_print(id, print_chat, "%s", g_szStringArray[x][Name])
    
    gCounter++
    if(gCounter == g_szStringArray[x][Number]){
        return// i want it to return the specific option Only whom gCounter reached
    }
    // then after it reached option 1, to spam only option 2 until gCounter reaches its Number
}

It's not quite clear what exactly you're requesting (because you use the term "limit" in one post and then "spam" in another which are effectively opposites). Could you please write out the sequence of messages that you want to occur. For example: "hello, hello, world, world, hello, hello" or "hello, hello, hello, world, hello hello hello, world", etc.

The modulus is not a bitwise operation and is a common question asked. Therefore, there are many articles/posts that explain how it works. For example, this one looks like it has a good explanation.

Prefixing a variable with "g" or "g_" is most often used to indicate a variable is a global variable so it's confusing when you have a variable (gCounter) that is not global.

[Natsheh]

Mostly likely global variables should be named all capital letters most recommended rather than using the g_ prefix.


The g_ prefix is a short cut for get.

Not in Pawn for AMX Mod X plugins. It's very common around here to use g_ as a prefix for global. I've never heard of using all caps for global variables. I've heard of using all caps for specific types of global variables, not all of them.
