public static void DrawScaleText(string text, int fonte, float x, float y, float size, int cor_red, int cor_green, int cor_blue, int Alpha, bool centralizado)
{
    float xc = x / 1920; // ScreenWidth
    float yc = y / 1080; // ScreenHeight
    API.SetScriptGfxDrawOrder(3);
    API.SetTextScale(size, size);
    Function.Call(Hash.SET_TEXT_CENTRE, centralizado); // centralized
    API.SetTextColor(cor_red, cor_green, cor_blue, Alpha); // COLOR: R G B Alpha
