# setup a project

- Find the projectGenerator.exe within sdk (of_v0.12.0_vs_release/projectGenerator/) and use it to create a project

That will create a VS project setup with the of lib.

# FRAMEWORK

main.cpp will open an ofBaseApp through the ofRunApp() method.

You'll need the basic ofApp.cpp of create your own extended ofBaseApp to feed that method.

Basic method given by ofBaseApp are :


    void setup();
    void update();
    void draw();
    void keyPressed(int key);
    void keyReleased(int key);
    void mouseMoved(int x, int y );
    void mouseDragged(int x, int y, int button);
    void mousePressed(int x, int y, int button);
    void mouseReleased(int x, int y, int button);
    void mouseEntered(int x, int y);
    void mouseExited(int x, int y);
    void windowResized(int w, int h);
    void dragEvent(ofDragInfo dragInfo);
    void gotMessage(ofMessage msg);

    ofBaseApp::setup for "constructor"
    ofBaseApp::update for heartbeat
    ofBaseApp::draw to draw stuff on screen (access to drawing routines)

# TROUBLESHOOT

## Created a class but can't include it

When creating a new class in VS you'll need to "add it to the project" through right click, add, existing
What you see in the Solution Explorer can differ from what is in the actual OS folder.

## Some issue with path to addons

The project needs to be located in the /Apps folder within the sdk. Relative paths ?
