[HOWTO] ShowMenus

Tobi17 · **Author**

Hello

I have created two functions to display a "ShowMenu" within the HLstatsX Plugin of sourcemod. This is the way to achieve this:

Code:

stock build_menu(player_index, String: message[230], time, finish = 1)
{
	decl Handle:hBf;
	hBf = StartMessageOne("ShowMenu", player_index);
	if (hBf != INVALID_HANDLE) {
		BfWriteShort(hBf, -1); 
		BfWriteChar(hBf, time);
		BfWriteByte(hBf, finish);
		BfWriteString(hBf, message);
		EndMessage();
	}
}

stock display_menu(player_index, time, String: full_message[1024])
{
	new String: display_message[1024];
	new offset = 0;
	new message_length = strlen(full_message); 
	for(new i = 0; i < message_length; i++) {
		if (i > 0) {
			if ((full_message[i-1] == 92) && (full_message[i] == 110)) {
				new String: buffer[1024];
				strcopy(buffer, (i - offset), full_message[offset]);
				if (strlen(display_message) == 0) {
					strcopy(display_message[strlen(display_message)], strlen(buffer) + 1, buffer); 
				} else {
					display_message[strlen(display_message)] = 10;
					strcopy(display_message[strlen(display_message)], strlen(buffer) + 1, buffer); 
				}
				i++;
				offset = i;
			}
		}
	}

	new String: partial_message[230];
	new maximum_splits = 5;
	new splits = 0;
	while ((splits < maximum_splits) && (strlen(display_message) > 0)) {
		if (strlen(display_message) > 230) {
			strcopy(partial_message, 230, display_message);
			build_menu(player_index, partial_message, time, 1);
			strcopy(display_message, 1024, display_message[229]);
		} else {
			strcopy(partial_message, 230, display_message);
			build_menu(player_index, partial_message, time, 0);
			display_message = ""
		}
		splits++;
	}
}

To display a ShowMenu you would have to execute for excample:

Code:

display_menu(client, 15, "This is a menu");

Multiple Lines are defined with:

Code:

display_menu(client, 15, "This is a menu\nwhich have multiple\nlines");

Remember the menu can currently not(!) respond to any key input (its not needed in HLstatsX). However it would be very cool if someone could explain how to handle the key triggers, currently all keys are valid and static defined.

Bye
