[ReVo_]

Ok, i understand you and you should be more specific (You first talk about a generic weapon then of a dialog)

top:

Код:

new bool:playerHaveWeapon[MAX_PLAYERS] = {false, ...};

OnPlayerSpawn

Код:

if (!playerHaveWeapon[playerid]) {
// Show the dialog
playerHaveWeapon [playerid] = true;
}

If you want to let the player to re-choose his weapons change playerHaveWeapon to false.
