Moscrif Framework includes two different libraries regarding game 2D development. If you require to use physics in your you might use Box2D library. If physics are not required, you may use game2D library.
Game project starts with Game instance. What the game should do at the start is defined within onStart method. Game instance also handle all input events came from the user on the device screen..
include "lib://core/log.ms";
include "lib://game2d/game.ms" //create new game instance
var game = new Game(); //run game
game.run();
The most significant events of the game instance are listed in the table below:
| Event name |
Description |
| onDraw |
Event fired when game is ready be drawn |
| onProcess |
Event fired when system idle allows to process the game |
| onStart |
Event fired when game is started |
| onPointerPressed |
Event fired when game is started |
| onPointerDragged |
Event fired when game is started |
| onPointerReleased |
Event fired when screen pointer is released |
Game instance is managing game scenes. Game.push method adds a game scene into Game instance and it displays the game scene on the device screen. Method Game.pop sets previous scene as the current scene and displays it on the device screen.
include "app://gui/menuScene.ms";
include "app://gui/snakeButton.ms";
//prepare game instance before it runs
game.onStart = function(sender)
{
this.terminate = false;
this.game = null; //Create menu scene
this.menu = new MenuScene();
this.push(this.menu); }
Game instance allows to use game Sprites, as well. To add a game sprite, use Game.add method. See example below where background is a instance of the Sprite with its own draw method added to Game instance.
game.onStart = function(sender)
{
//load background
this.bg = new Sprite({image : Bitmap.fromFile("app://gfx/bg.png")});
this.bg.draw = function(canvas)
{
//draw background
canvas.drawBitmap(this.image, 0, 0);
}
this.add(this.bg)
}
