# My-Windows-Game-Engine

My own graphic engine.

(Currently works for every version of Window)

## What can you do ?

* Draw circles, ellipses, rectangle, polygons.

* Read input from keyboard and mouse (pressed, held, released, toggled).

* Colors ! (Now RGB only but i'm working to add Alpha).

* Lock FPS ( from 1 to 1000! ).

* Set Window Title.

* Run in multithreading so FASTER on multicore machines.

* I will add Surfaces, vector2d, vector3d, some helpful math's equations and others !.

## How to install it

### DevCpp

1. Create New Project (Empty Project / Console Application)

2. Go to Project->Project Options->Parameters->Add Library or object. Browse into C:\somthing\GEngine\bin\libGEngine.a and Select it.

3. Paste "-lgdi32 -lwinmm -lws2_32" inside Linker box (_You need to complete second before !)

4. Go to Project->Project Options->Directories->Include Directories. Browse into C:\somthing\GEngine\src, Select it and click on "ADD".

5. Then you can #include  and use my library !

## How to use it

### Basics

```c++

#include 

/** Create a class and inherit from GEngine

  * You must define onStart() and onUpdate(float dt)

  * otherwise it will be abstract.

  **/

class Engine: public GEngine

{

  public:

    // This function will be called when the game start or restart.

    bool onStart()

    {

      // Return true if all worked correctly

      return true;

    }

    

    // Every frame the engine will call this function

    bool onUpdate(float dt)

    {

      clear(Color::Black);                          // Clear background with black

      drawRect(400, 300, 100, 100, Color::Blue);    // Draw a simple 100px width 100px height blue rectangle

      

      if(KeyBoard::GetKeyState(KeyBoard::K_W).held) // Check if W is held

       drawRect(500, 300, 100, 100, Color::Red)     // Draw a 100px width 100px height red rectangle

      

      // Its important to return true if you dont want to close the application

      return true;

    }

    

    // optional

    bool onDestroy()

    {

      // This function is called when Game Loop is over.

      // You can return true if you want to close or false if you want to restart the game.

      return true;

    }

};

int main()

{

  // Create an instance.

  Engine demo;

  

  // Initialize the window (width, height) in pixels.

  if(demo.init(800, 600))

  

      // If all is gone correctly you can run your game !

      demo.run();

  

  return 0;

}

```
