Yea dude, you really need to learn to use ****** and learn to script

But since I'm not entirely an asshole, here, this is an example:

pawn Код:

// Somewhere not in a function.  Global Variable
new ActiveCheckpoint[MAX_PLAYERS];

//Wherever you want to set the checkpoint
ActiveCheckpoint[playerid] = 1;
SetPlayerCheckpoint(playerid, -2034.9296, 178.9917, 28.8429, 3.0);

//The OnPlayerEnterCheckpoint Function

public OnPlayerEnterCheckpoint(playerid)
{
    if(ActiveCheckpoint[playerid] == 1)
    {
        //if they enter the checkpoint you set
        ShowPlayerDialog(blablabla); //Your dialog here to open
    }
    return 1;
}
