Enter / Exit - vIBIENNYx - 23.05.2012

So far I have this:

pawn Код:

command(enter, playerid, params[])
{
    switch(arrowpickup[])
    {
    //
    }
    return 1;
}

I have the pickups declared and they display, they are also entered into the array shown below:

pawn Код:

// Arrow Array
new arrowpickup[100];

stock showarrowpickups()
{
  arrowpickup[1] = CreatePickup(1318, 1, -2440.8452, 524.1761, 29.9064, -1);
  arrowpickup[2] = CreatePickup(1318, 1, -2453.5320, 504.0138, 30.0802, -1);
  print("Arrow Pickups loaded");
  
}

The error is on the "switch" line, the error is: "bensamp.pwn(944) : error 029: invalid expression, assumed zero".

Can anyone please help me? Or see as to where I have gone wrong.

Switch statements can only be used for integers.

pawn Код:

arrowpickup[]

is a string.

Re: Enter / Exit - vIBIENNYx - 23.05.2012

Okay, how should I turn it into an integer?

Basically, I'm trying to assign an ID to the pickup, and use the ID in the case statement rather than writing a million if statements.

Re: Enter / Exit - Jonny5 - 23.05.2012

actually it looks like an array of ids to me.

i think this is something closer to what you want.

pawn Код:

command(enter, playerid, params[])
{
    new param = strval(params);
    switch(param)
    {
        case arrowpickup[0] : 
        {
        //some code here
        }
        case arrowpickup[1] : 
        {
        //some code here
        }
    }
    return 1;
}

    return 1;
}

Thank you very much, I cannot add this into my code right now but I will asap. Repped.

That looks good but, I'm trying to use as little includes and I would rather it be a command rather than just run into it and TP, thanks though mate ^^

You can't have variables as cases in a switch statement. You should save the location of the pickups in a variable and loop through it.

In PAWN you can have variables as cases.

pawn Код:

public OnPlayerPickUpPickup(playerid, pickupid) //don't know why you would use a command to enter pickups
{
    switch(pickupid)
    {
        case arrowpickup[1]:
        {
            //do stuff
        }
        case arrowpickup[2]:
        {
            //do stuff
        }
    }
}

        {
            //do stuff
        }
    }
}

I get two errors regarding the two cases themselves.

pawn Код:

C:\Users\Ben\Desktop\SF-RP\gamemodes\bensamp.pwn(542) : error 008: must be a constant expression; assumed zero
C:\Users\Ben\Desktop\SF-RP\gamemodes\bensamp.pwn(546) : error 008: must be a constant expression; assumed zero

Not to sure what the error is either.
