示例​

new PlayerText:pVehicleHealthTD[MAX_PLAYERS];
new pVehicleHealthTimer[MAX_PLAYERS];

public OnPlayerStateChange(playerid, PLAYER_STATE:newstate, PLAYER_STATE:oldstate)
{
    if (newstate == PLAYER_STATE_DRIVER) // 以驾驶员身份进入车辆
    {
        pVehicleHealthTD[playerid] = CreatePlayerTextDraw(playerid, 320.0, 240.0, " ");
        PlayerTextDrawShow(playerid, pVehicleHealthTD[playerid]);

        // 设置每秒更新文本绘图的计时器
        pVehicleHealthTimer[playerid] = SetTimerEx("UpdateVehicleHealthTextDraw", 1000, true, "i", playerid);
    }
    if (oldstate == PLAYER_STATE_DRIVER) // 退出驾驶状态
    {
        KillTimer(pVehicleHealthTimer[playerid]);
        PlayerTextDrawDestroy(playerid, pVehicleHealthTD[playerid]);
    }
    return 1;
}

forward UpdateVehicleHealthTextDraw(playerid);
public UpdateVehicleHealthTextDraw(playerid)
{
    new
        string[32],
        vehicleid = GetPlayerVehicleID(playerid),
        Float:health;

    GetVehicleHealth(vehicleid, health);

    format(string, sizeof(string), "车辆耐久: %.0f", health);
    PlayerTextDrawSetString(playerid, pVehicleHealthTD[playerid], string); // <<< 更新显示车辆耐久度

    // 专业建议：open.mp中可直接使用以下简化写法
    PlayerTextDrawSetString(playerid, pVehicleHealthTD[playerid], "车辆耐久: %.0f", health);
    return 1;
