Member Function Documentation

step()

void step ( )

overridevirtual

Advance the game logic.

This function gets called 60 times per second or whatever has been set by setStepsPerSecond().

Note

JNGL's main loop calls all Jobs' step() functions before the active Work's step()

Implements Job.

draw()

void draw ( ) const

overridevirtual

Draw the game state.

As it isn't garuanteed that this function is called as often as Job::step, you shouldn't change any game state in it.

Note

JNGL's main loop calls all Jobs' draw() functions after the active Work's draw()

Implements Job.

onQuitEvent()

void onQuitEvent ( )

overrideprivatevirtual

Gets called when the user closes the main window or quit() has been called.

To continue with the main loop, call cancelQuit(). For example if you want to switch to a pause menu instead of exiting the game:

class Game : public jngl::Work {
    void onQuitEvent() {
        jngl::cancelQuit();
        jngl::setWork<PauseMenu>();
    }
};

Reimplemented from Work.
