Help with HudMessage

Elusive13 · **Author**

Hello. I started making a message that reads the text from a separate file. After doing this, I found that the message could not be divided into separate lines in the text file (messages.ini). How do I fix this?

Code:

#include <amxmodx>

public plugin_init() {
	
    register_plugin("Welcome Hud Message", "1.3", "Nobi13")
}

public WelcomeHudMessage(id) {
	
	new file = fopen("addons/amxmodx/configs/messages.ini", "rt");
	new msg[1001]
		set_hudmessage(/* RGB Color set*/0, 80, 255, /*Float:x =*/ -1.0, /*Float:y = */0.18, /* effects =*/ 2, /* Float:fxtime = */ 3.0, /*Float:holdtime = */15.0, /*Float:fadeintime = */0.1, /*Float:fadeouttime = */ 1.5, /*bool:reliable =*/ false )
		fgets(file, msg, charsmax(msg))
		fclose(file)
		show_hudmessage(id,msg)
}
   	
public client_putinserver(id) {
   set_task(10.0, "WelcomeHudMessage",id) //After how many seconds to be showed
  }

You must use ^n in text to divide the text into separates link.
Example:

Code:

Welcome to our server!^nType 'm' to choose a team

will display

Code:

Welcome to our server!
Type 'm' to choose a team

I want to split messages into the .ini file not in .sma

And what will you do with those lines later?

you put

Quote:

upper text^nlower text

in your config file, then in plugin you open this file, read the line, format it and show to player via show_hudmessage(). Users will see

Quote:

upper text
lower text

What's else?

you can read line by line

What is this "i"before "File" var,what mean that g_szMessage or szFile

"i" before "File" represent a prefix before the name of the variable. you can declare variable names how you want, but using that prefixes would help you to code faster

integer -> new iFile
string -> new szFile[64]
float -> new Float:fFile
boolean -> new bool:bFile

global integer variable -> g_iFile
and so on

probably supremache didn t paid enough attention or he just copied the code from another plugin, but the g_szFile[128] should be szFile[128] because it s not a global variable and it is a string where the file path is stored.

PHP Code:


			
new iFile = fopen( g_szFile, "rt" );

here, native fopen return file pointer (it s like a identifier for the specified file, if you want to see what fopen parameters do, you can read here: https://www.amxmodx.org/api/file/fopen)

the g_szMessage is a global variable where the message is stored after the plugin read it from the file. as you can see, he declared the variable above the plugin_init and because is not declared in a function the variable is global

Do I understand that all variables that are not in function are global? I can use these prefixes in variables and they don't depend directly on libraries, right?

And one question about the plugin, specifically about the code. Do I have to declare so many functions and variables to be able to use the functions of the .sma file in the config file, as in this case I replace the newline function (^n) with (!n) or whatever I decide except the characters that are forbidden?
Can i just do this

PHP Code:


			
 replace_all (g_szMessage, charsmax (g_szMessage), "!n", "^n")

without doing the whole check?
