Hello. There is a plugin that gives a bazooka automatically to all players. I want to make the plugin to not give bazooka to bots, bot only to real players.

At the top of the following code:

Code:

/*================================================================================
 [Zombie Plague Forwards]
=================================================================================*/

public zp_user_infected_post(id, infector)
{

	// User is Nemesis
	if(zp_get_user_nemesis(id))
	{
		// Plugin enabled
		if(g_bCvar_Enabled) 
		{
			// Check cvar
			if(g_bCvar_GiveFree) // Free
			{
				// Give gun
				set_user_nrlauncher(id, 1)
			}
			// User must buy
			else 
			{
				// Reset Vars
				set_user_nrlauncher(id, 0)
				
				// Messages
				set_task(1.5, "nrl_hudmessage", id)
				client_printcolor(id, "/g[Hell Hole]/y %L", id, "NRL_PRINT_BUY")
				client_printcolor(id, "/g[Hell Hole]/y %L", id, "NRL_PRINT_HELP")
			}
		}
	}
	// is Zombie
	else
	{
		// Reset Vars
		set_user_nrlauncher(id, 0)
	}
}

public zp_user_humanized_post(id)
{
	// Reset Vars
	set_user_nrlauncher(id, 0)
}

public zp_round_ended(team)
{
	// Remove all the rockets in the map
	// remove_rockets_in_map()
	set_task(0.1, "remove_rockets_in_map")
	
	// Update var
	g_bRoundEnding = true
}

I add the following code:

Code:

	// Preventing bot users from receiving the bazooka
	if(is_user_bot(id))
	return PLUGIN_HANDLED

So, the code can be like this:

Code:

/*================================================================================
 [Zombie Plague Forwards]
=================================================================================*/

public zp_user_infected_post(id, infector)
{

	// Preventing bot users from receiving the bazooka
	if(is_user_bot(id))
	return PLUGIN_HANDLED

	// User is Nemesis
	if(zp_get_user_nemesis(id))
	{
		// Plugin enabled
		if(g_bCvar_Enabled) 
		{
			// Check cvar
			if(g_bCvar_GiveFree) // Free
			{
				// Give gun
				set_user_nrlauncher(id, 1)
			}
			// User must buy
			else 
			{
				// Reset Vars
				set_user_nrlauncher(id, 0)
				
				// Messages
				set_task(1.5, "nrl_hudmessage", id)
				client_printcolor(id, "/g[Hell Hole]/y %L", id, "NRL_PRINT_BUY")
				client_printcolor(id, "/g[Hell Hole]/y %L", id, "NRL_PRINT_HELP")
			}
		}
	}
	// is Zombie
	else
	{
		// Reset Vars
		set_user_nrlauncher(id, 0)
	}
}

public zp_user_humanized_post(id)
{
	// Reset Vars
	set_user_nrlauncher(id, 0)
}

public zp_round_ended(team)
{
	// Remove all the rockets in the map
	// remove_rockets_in_map()
	set_task(0.1, "remove_rockets_in_map")
	
	// Update var
	g_bRoundEnding = true
}

When i try to compile the plugin, i get the following warning:

warning 209: function "zp_user_infected_post" should return a value

Can someone tell me how to fix this warning?

CrazY.

Remove PLUGIN_HANDLED, keep the return only.

Code:

if(is_user_bot(id))
	return

The warning literally tells you to return a value.
Either use "return" with no value, or return a value in the end of the function.

Now, it works.

Thanks.

The warning said i have to return a value, but now it works only with "return", without any value attached to "return".

The warning said there should be a value, and this value was "PLUGIN_HANDLED". However, the warning came exactly from the "PLUGIN_HANDLED" value, but the warning disappeared when i removed the "PLUGIN_HANDLED" value, meaning no value was actually needed.

See? It shows it needs a value, then shows a warning when a value is added, and then works fine when the value is removed...
