Questions about "for" loop

How does the for loop respond too "continue", "break" and "return" ?

If i want to stop looping and jump to the code after the loop after some condition is satisfied which one should i use.

Example:

PHP Code:


		
			
public myfunc(id)
{
          for(new i = 1; i <= max_players; i++)
          {
                   if(some condition that was satisfied)
                   {
                   want to stop looping 
                   return/continue/break ?
                   }
          }

          Still want to execute this code(id)
          {

          }

}

If i want to jump to the next loop in the same condition then which one ?

Similarly if i want to just return the value and stop executing the ENTIRE function then ?

Re: Questions about "for" loop

return will stop the entire function "myfunc"

continue will stop the current iteration of the loop, and begin the next one

break will stop the loop immediately, and continue on with the rest of the function.

Re: Questions about "for" loop

Is returning in loop a good way? I have always broke it, then return.

If you refer to this

Code:

break
return

It's invalid, the compiler will throw a warning, because you have no reason to do it.
I don't see a problem in using "return" in a loop, if you don't want to continue with the function, if the loop reach something, return is just fine. This all depends on what you need.

Code:

loop
{
    if( iterator % 3 == 0 )
    {
         break
    }
}
//some code here
//end of public

By using break the block of code outside the loop will still execute. If you will use return it won't.

Re: Questions about "for" loop

should i "break" somewhere the loop here ?. ( this is blocking some items for others after 1 user bought one time in 1 map )

PHP Code:


		
			
else  if (itemid == g_survivor)
        {
            if(has_mod[player])
            {
                chat_color(player, "!g[StreetZM]!y You !galready have bought !ymod in this map!")
                return ZP_PLUGIN_HANDLED;
            }
            if(has_survivor[player])
            {
            chat_color(player, "!g[ZP]!y It!g was a Survivor!y in this map!")
            return ZP_PLUGIN_HANDLED;
            }
            zp_make_user_survivor(player)
            has_mod[player] = true
            for (player = 1; player <= g_maxplayers; player++)
            {
            has_survivor[player] = true
            }
        }
else  if (itemid == g_sniper)
        {
            if(has_mod[player])
            {
                chat_color(player, "!g[StreetZM]!y You !galready have bought !ymod in this map!")
                return ZP_PLUGIN_HANDLED;
            }
            if(has_sniper[player])
            {
            chat_color(player, "!g[StreetZM]!y You !galready have bought mod !yin this map!")
            return ZP_PLUGIN_HANDLED;
            }
            zp_make_user_sniper(player)
            has_mod[player] = true
            for (player = 1; player <= g_maxplayers; player++)
            {
            has_sniper[player] = true
            }
        }
        g_buyable = false    
        return PLUGIN_CONTINUE
}

Re: Questions about "for" loop

Why you need it? I don't see that it can be useful in your situation. ;)

ah, ok :P i thought yes :D

Re: Questions about "for" loop

Its fine to use return in loop. Other ways we could not use it there if it would not be fine.

Re: Questions about "for" loop

continue - skip to the next step.
break - breaks the loop.
return - breaks the loop and blocking from the rest of the fuction calling
