Create- and DestroyObject. - Ihsan-Cingisiz - 28.01.2011

Hello,

I want to update my weed system with getting a plant on the ground.
So, for example:

pawn Код:

if(strcmp(cmd, "/plant", true) == 0)
{
            new Float:X, Float:Y, Float:Z;
            GetPlayerPos(playerid, X, Y, Z);
            new a = CreateObject(688, X, Y, Z, 0.0, 0.0, 96.0);
}

okay, and now..?

I made that 'a' because when the player types /pickweed, the object
needs to be destroyed.. Okay, what should i do now? Anyone ideas?

PS: Which is the best ObjectID for the drug plant?

Re: Create- and DestroyObject. - Kwarde - 28.01.2011

You're using the local function 'a'. Make it global. So:

pawn Код:

//In the range of includes:
new PlayerDrugWeed[MAX_PLAYERS] = (-1);

//In the command:
PlayerDrugWeed[playerid] = CreateObject(...);

//To destroy:
DestroyObject(PlayerDrugWeed[playerid]);
PlayerDrugWeed[playerid] = (-1);

And I don't know that fast what the best id for drug plant is. Try looking on samp wiki

Well if you declare the variable a in the command, it's scope will be limited to that command. You would need something like a PVar.

pawn Код:

if(!strcmp(cmd, "/plant", true))
{
    if(GetPVarInt(playerid,"WeedID") != -1)
    {
        //They already planted one
        return 1;
    }
    new
        Float:X,
        Float:Y,
        Float:Z,
        Float:A;
        
    GetPlayerFacingAngle(playerid,A);
    GetPlayerPos(playerid, X, Y, Z);
    
    X += (4 * floatsin(-A, degrees));
    Y += (4 * floatcos(-A, degrees));
    
    SetPVarInt(playerid,"WeedID",CreateObject(688, X, Y, Z, 0.0, 0.0, 96.0));
    return 1;
}
if(!strcmp(cmd, "/pickweed", true))
{
    if(GetPVarInt(playerid,"WeedID") == -1)
    {
        //They haven't planted one
        return 1;
    }
    DestroyObject(GetPVarInt(playerid,"WeedID"));
    SetPVarInt(playerid,"WeedID",-1);
    //Rest of your pick weed code
    return 1;
}

    DestroyObject(GetPVarInt(playerid,"WeedID"));
    SetPVarInt(playerid,"WeedID",-1);
    //Rest of your pick weed code
    return 1;
}

Hmm... I'd like to use this but i never paid attention to PVar, so i don't exactly know how
that works. And what do you exactly mean with the -1, can it just be 10 or something?

-1 is mostly an invalid 'integer'. If you make a new variable for an object for a player, make it (-1);
new var[MAX_PLAYERS] = (-1);
CreateObject returns the spawned object ID. The very first object will be ID 0 (everything begins with '0' with counting instead of '1' in script languages).
So when the var is '-1' is means that it's "invalid", so "not spawned".

And about PVars: It's almost the same as normal variables.
Examples:

pawn Код:

new Nothing[MAX_PLAYERS];
Nothing[playerid] = 1;

is the same as

pawn Код:

SetPVarInt(playerid, "Nothing", 1);

With PVar's you don't need to define variables first. PVar's can also hold bigger strings. But they are not faster!
More examples:

pawn Код:

new Float:PosX[MAX_PLAYERS];
PosX[playerid] = 0.0;

is the same as

pawn Код:

SetPVarFloat(playerid, "PosX", 0.0);

And

pawn Код:

new PlayerText[MAX_PLAYERS][50];
strins(PlayerText[playerid], "I am Kwarde!", 0, strlen("I am Kwarde!"));

Is the same as

pawn Код:

SetPVarString(playerid, "PlayerText", "I am Kwarde!");

You can check it with the following functions.

Integer:
GetPVarInt(playerid, {var});

Float:
GetPVarFloat(playerid, {var});

String:
GetPVarString(playerid, {var});]

Example of getting the "Nothing" of the playerid...
The normal one:

pawn Код:

if(Nothing[playerid] == 1) print("OK");

The PVar

pawn Код:

if(GetPVarInt(playerid, "Nothin") == 1) print("OK");

It ain't hard

You can also remove PVars, with normal strings you can't (as far as I know)

DeletePVar(playerid, {var});
So, to remove the "Nothing":

pawn Код:

DeletePVar(playerid, "Nothing");

Thanks for your tutorial!

I'm gonna use this for sure! Thanks again!
