C++ (Cpp) INTERACTOR::Update Examples

Example #1

//Perform per frame updates
void UpdateFrame()
{
	window.Update();
	camera.Update();

	//Change object type
	if(window.isKeyPressed(' '))
	{
		++objectType;
		if(objectType==3)
			objectType=0;

		window.SetKeyReleased(' ');
	}

	//Change render path
	if(window.isKeyPressed('1') && renderPath!=CHROMATIC_SINGLE && pathOneSupported)
	{

		InitChromaticSingleStates();
	}
	
	if(window.isKeyPressed('2') && renderPath!=SIMPLE_SINGLE)

		//Set States every pass, as it is a 2 pass algorithm
	}
}
