[Solved] read char by char from arguments (and other questions)

nacknic · **Author**

its my third day of learning pawn/amxmodx... , and im new in this forum.

i want to read char by char from arguments, read_args()/read_argv() not helped.
after hour, found getarg(), and i think that`s what i needed, but when i print, instead of char, i get N, why ?

Code:

 
/* Plugin generated by AMXX-Studio */

#include <amxmodx>
#include <amxmisc>

#define PLUGIN "New Plug-In"
#define VERSION "1.0"
#define AUTHOR "nacknic"


public plugin_init() {
	register_plugin(PLUGIN, VERSION, AUTHOR)
	register_clcmd("say", "xmath")
}

public xmath(id)
{
	new args[51], len_args, i = 0, c[51]
	read_args(args, charsmax(args))
	len_args = strlen(args)
	while(i <= len_args)
	{
		client_print(id, print_chat, "%c", getarg(i))
		client_print(id, print_chat, "next char:")
		i++
	}	
}

next question: what setarg() do ? by name its set, but cant be true argumnets that somthing you get....

next question: if i want call function from function, how i do that ?

Code:

public fun1(id)
{
         new x, y
         fun2(x, y)
}

public fun2(x , y)
{
         z = x + y
}

last question: why it`s not write what the warning is ?

PHP Code:


			
#include <amxmodx>
#include <amxmisc>

#define PLUGIN "New Plug-In"
#define VERSION "1.0"
#define AUTHOR "nacknic"


public plugin_init() {
    register_plugin(PLUGIN, VERSION, AUTHOR)
    register_clcmd("say", "xmath")
}

public xmath(id)
{
    new szText[64];
    read_args(szText, charsmax(szText));
    remove_quotes(szText);
    new iLen = strlen(szText);

    for(new i; i < iLen; i++) {
        client_print(id, print_chat, "Char #%d: %c", i, szText[i]);
    }
}

PHP Code:


			
public funcToCaLlFrom(id)
{
         new x, y;
         funcToCall(x, y);
}

public funcToCall(x, y)
{
    new z;
    z = x + y;
}

Probably indentation (make sure you indent with tabs, not spaces).

1.2. set/getarg are core natives for direct work with function arguments mostly for making APIs (specifically in case you have an unknown number of them), you'd probably never use them though. dhudmessage.inc uses them to parse multilingual strings, for example.

3. If you want to use that function to get the value of the sum, you can directly

PHP Code:


			
return x + y

4. Scroll up, lol. In your case, you got a warning because the c[51] array is never used.

thank you for answer me with real code (and not just explanation, pawn and amxmodx new to me so its really helps) i`m glad to be member in this support community.
i have more two very simple questions:
#5 how i write notes in other language //non-english (its give gibberish (unknown words)).
#6 how print in this command client_print(id, print_chat, " ") in other language

ok, i never use get/setarg()... I will not bother to laern what they do.
so all native function not really useful ?

and about the example that i write fuction call function for sum, i know i can do it in one function,
but my real goal was to learn how call function from another function.

and thank you the command about warning to scroll LOL

PHP Code:


			
public fun1(id)
{
         new x, y
         fun2(x, y)
}

public fun2(x , y)
{
         z = x + y
}

Looks fine to me, what is the issue?

no issue its the part of answer he give me...
if here two questions please:
#5 how i write notes in other language //non-english (its give gibberish (unknown words)).
#6 how print in this command client_print(id, print_chat, " ") in other language

Just write the message in another language?

Obviously there is a better way, the ML system which allows you to store messages in a file for multiple languages and it will automatically choose the right version for the player, but since you are a beginner I wouldn't bother with it for now.

thanks to your help, i success what i want to do:
in your script you do loop and print string/sub-strings like chars by usin %c in print coomand.
i added format() because i want really change to chars to read and exam char by char:

Code:

#include <amxmodx>
#include <amxmisc>

#define PLUGIN "New Plug-In"
#define VERSION "1.0"
#define AUTHOR "nacknic"


public plugin_init() {
    register_plugin(PLUGIN, VERSION, AUTHOR)
    register_clcmd("say", "xmath")
}

public xmath(id)
{
    new args[64], c[64];
    read_args(args, charsmax(args));
    remove_quotes(args);
    new iLen = strlen(args);

    for(new i; i < iLen; i++) {
    	format(c[i], charsmax(c), "%c", args[i]);
    }
    
    if(c[0] == '!' && c[1] == 'c') client_print(id, print_chat, "work");
    else client_print(id, print_chat, "didn't works");
}

is there efficient way , read char and not format to char like i do ?
