GameHelperBase

This is the base class for your game. Create a class based on this, then pass it to runGame.

abstract

class GameHelperBase {

void drawFrame(float interpolateToNextFrame);

bool update();

SimpleWindow getWindow();

bool wantAudio();

bool multithreadCompatible();

AudioOutputThread audio;

protected

bool redrawForced;

void showScreen(Screen cs, GameScreenBase transition);

GameScreenBase firstScreen();

int designFps();

void forceRedraw();

JoystickUpdate[4] joysticks;

bool[256] keyboardState;

VirtualController snes;

}

Functions

designFps int designFps(): Returns the number of game updates per second your game is designed for.
drawFrame deprecated void drawFrame(float interpolateToNextFrame): Implement this to draw.
firstScreen GameScreenBase firstScreen(): Returns the first screen of your game.
forceRedraw void forceRedraw(): Forces a redraw even if update returns false
getWindow SimpleWindow getWindow(): Returns the main game window. This function will only be called once if you use runGame. You should return a window here like one created with create2dWindow.
multithreadCompatible bool multithreadCompatible(): Override this and return true if you are compatible with separate render and update threads.
showScreen void showScreen(Screen cs, GameScreenBase transition): Shows the given screen, making it actively responsible for drawing and updating, optionally through the given transition effect.
update deprecated bool update(): Implement this to update your game state by a single fixed timestep. You should check for user input state here.
wantAudio bool wantAudio(): Override this and return true to initialize the audio system. If you return true here, the audio member can be used.

Variables

audio AudioOutputThread audio;: You must override wantAudio and return true for this to be valid;
joysticks JoystickUpdate[4] joysticks;: These functions help you handle user input. It offers polling functions for keyboard, mouse, joystick, and virtual controller input.
snes VirtualController snes;
