tested, it works

PHP код:

public OnPlayerKeyStateChange(playerid,newkeys,oldkeys){
    
    if(HOLDING(KEY_FIRE) && GetVehicleModel(GetPlayerVehicleID(playerid)) == 407) {
        new Float:fAimingCoords[5],Float:NewCoords[3],Float:pos[3];
        GetVehiclePos(GetPlayerVehicleID(playerid),fAimingCoords[0],fAimingCoords[1],fAimingCoords[2]);
        GetPlayerCameraRotation(playerid,fAimingCoords[3],fAimingCoords[4]);
        
        GetPointInFront3D(fAimingCoords[0],fAimingCoords[1],fAimingCoords[2],fAimingCoords[3],fAimingCoords[4],10.0,NewCoords[0],NewCoords[1],NewCoords[2]);
        //Here you can do loops searching fire
        GetDynamicObjectPos(vatra[0],pos[0],pos[1],pos[2]);
        if(IsPointNearly2Points3D(pos[0],pos[1],pos[2],fAimingCoords[0],fAimingCoords[1],fAimingCoords[2],NewCoords[0],NewCoords[1],NewCoords[2],3.0)){
            DestroyDynamicObject(vatra[0]);
        }
        
    }
    
    return 1;
}
