在当前为对象的另一个类内部调用类函数

new here，所以要温柔，我目前正在为我的课程做我的主要项目，我不是要求为我做作业，我只是不能把我的头缠绕在一个奇怪的问题上，我有，没有能够找到答案，即使在这里。我正在使用SDL为我的绘图。

我正在做面向对象编程与我的项目或"状态机"(这听起来不那么痛苦在一个新手的头脑，相信我)，并在我的类Game1.cpp的渲染部分，我试图调用我的玩家类的绘制函数，但由于一些未知的原因，我无法理解，它只是完全跳过这个函数调用。

我没有错误，我甚至使用断点来找出发生了什么，但它每次都完全跳过它，它也没有失败地绘制屏幕黑色。如果你能帮助我为什么跳过这个，我将非常感激。

老实说，我觉得这是一个简单的新手错误，但任何和所有的审查我的代码是受欢迎的，任何我能做的更好的自己是感激的。

Game1.cpp:

#include "Game1.h"

Game1::Game1( World * worldObject )
{
    //object setup
    this->worldObject = worldObject;
    setDone (false);
}
Game1::~Game1()
{
}
void Game1::handle_events()
{
