Nibbler - Swapable graphics plugin snake clone

This project focuses on implementing simple plugin system in c++
using dynamic libraries.

These plugins are used to provide differant rendering
and input interfaces to a game of snake.

Plugins

Each Plugin implements the following interface:

struct Input
{
	bool	left;
	bool	right;
	bool	up;
	bool	down;
	bool	close;
	bool	one;
	bool	two;
	bool	three;
};

class IGraphic
{
protected:
	IGraphic(void) {}
	
public:
	virtual ~IGraphic(void) {};
	virtual void Draw(glm::ivec2, char) = 0;
	virtual void Display(void) = 0;
	virtual Input Input(void) = 0;
	virtual void Destroy(void) = 0;
};

Each dynamic library provides an extern function like so:

extern "C" IGraphic* load(glm::ivec2 dimensions) 
{
	return (new <Graphic>(glm::ivec2 dimensions));
}

where <Graphic> is the name of the IGraphic implementing class.

They are dynamically loaded through dlopen and dlsym
and can be switched live with the 1, 2, and 3 keys.

Dependencies

install all dependencies with brew.
