[Threshold]

pawn Код:

#define PICKUP_DELAY 5
//This means you want 5 second delays between pickups. You can change this to whatever you want.
new LastPickup[MAX_PLAYERS];

public OnPlayerConnect(playerid)
{
    LastPickup[playerid] = 0; //Reset the LastPickup for the player.
    return 1;
}

public OnPlayerPickUpPickup(playerid, pickupid)
{
    if((gettime() - LastPickup[playerid]) < PICKUP_DELAY) return 1;
    if(pickupid == 1) //Example
    {
        //Your code
    }
    LastPickup[playerid] = gettime();
    return 1;
}

The #define and new LastPickup would have to be at the top of your script.

pawn Код:

if((gettime() - LastPickup[playerid]) < PICKUP_DELAY) return 1;

This line prevents the code from continuing if it hasn't been 5 seconds since their last pickup.
