arsd.game

An add-on for simpledisplay.d, joystick.d, and simpleaudio.d that includes helper functions for writing simple games (and perhaps other multimedia programs). Whereas simpledisplay works with an event-driven framework, arsd.game always uses a consistent timer for updates.

Usage example:

final class MyGame : GameHelperBase {
	/// Called when it is time to redraw the frame
	/// it will try for a particular FPS
	override void drawFrame() {
		glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_ACCUM_BUFFER_BIT);

		glLoadIdentity();

		glColor3f(1.0, 1.0, 1.0);
		glTranslatef(x, y, 0);
		glBegin(GL_QUADS);

		glVertex2i(0, 0);
		glVertex2i(16, 0);
		glVertex2i(16, 16);
		glVertex2i(0, 16);

		glEnd();
	}

	int x, y;
	override bool update(Duration deltaTime) {
		x += 1;
		y += 1;
		return true;
	}

	override SimpleWindow getWindow() {
		auto window = create2dWindow("My game");
		// load textures and such here
		return window;
	}

	final void fillAudioBuffer(short[] buffer) {

	}
}

void main() {
	auto game = new MyGame();

	runGame(game, maxRedrawRate, maxUpdateRate);
}

It provides an audio thread, input scaffold, and helper functions.

Members

Classes

GameHelperBase class GameHelperBase: This is the base class for your game.
OpenGlTexture class OpenGlTexture: Simple class for putting a TrueColorImage in as an OpenGL texture.

Functions

clearOpenGlScreen void clearOpenGlScreen(SimpleWindow window)
create2dWindow SimpleWindow create2dWindow(string title, int width, int height): Creates a simple 2d opengl simpledisplay window. It sets the matrix for pixel coordinates and enables alpha blending and textures.
runGame deprecated void runGame(GameHelperBase game, int maxUpdateRate, int maxRedrawRate): Deprecated, use the other overload instead.
runGame void runGame(int maxUpdateRate, int maxRedrawRate): Runs your game. It will construct the given class and destroy it at end of scope. Your class must have a default constructor and must implement GameHelperBase. Your class should also probably be final for performance reasons.

Structs

VirtualController struct VirtualController: The virtual controller is based on the SNES. If you need more detail, try using the joystick or keyboard and mouse members directly.

Detailed Description

The MyGame handler is actually a template, so you don't have virtual function indirection and not all functions are required. The interfaces are just to help you get the signatures right, they don't force virtual dispatch at runtime.
