Hey Guys, I am new to Sparrow and have pretty much made my game. my only problem is it jumps right into the game on launch, but I saw this via google
http://www.sparrow-framework.org/2010/05/creating-a-game-menu/comment-page-1/#comment-884
I would like to add a menu, how would I, would I add a view controller, but then what would I edit and how could I make it launch the game?
thanks guys
Hi skippertech,
first of all: welcome to the Sparrow forum! Great to hear that you're using Sparrow for your game =)
There is, unfortunately, no detailed tutorial for that available, at least none that I know of. But the topic was at least discussed in the following 2 forum threads -- perhaps that gets you started!

Ok, i never did something useful for this community so i would like to try to remedy^^'
I'm also in trouble learning Cocoa so i decided that my first experiment will be entirely done within the Sparrow framework... i'll have time to add cocoa's native features in a second release if the first one will have some kind of success.
This is a way to add menus using only Sparrow's syntax:
#import "Game.h" @implementation Game -(id)initWithWidth:(float)width height:(float)height { // we start showing the mainMenu // - we also set a container for our game's elements if (self = [super initWithWidth:width height:height]) { mContents = [SPSprite sprite]; mContents = [[SPSprite alloc] init]; [self addChild:mContents]; [self mainMenu]; } return self; } -(void)mainMenu{ // add the main menu to the stage // - we add a background image and a button to start mainMenuImage = [SPImage imageWithContentsOfFile:@"mainMenuBkg.png"]; mainMenuScreen = [SPSprite sprite]; [mainMenuScreen addChild:mainMenuImage]; [mContents addChild:mainMenuScreen]; startButton = [SPButton buttonWithUpState:[SPTexture textureWithContentsOfFile:@"buttonStart.png"]]; [mainMenuScreen addChild:startButton]; [startButton addEventListener:@selector(onStartButtonTriggered:) atObject:self forType:SP_EVENT_TYPE_TRIGGERED]; } -(void)onStartButtonTriggered:(SPEvent*)event{ // make the game start [self start]; } -(void)start{ // begin a new game // - here we set all our game's variables and start the main game cycle [mContents removeAllChildren]; hero = [SPImage imageWithContentsOfFile:@"hero.png"]; [mContents addChild:hero]; hero.x = 0; [self addEventListener:@selector(onEnterFrame:) atObject:self forType:SP_EVENT_TYPE_ENTER_FRAME]; } -(void)onEnterFrame:(SPEnterFrameEvent *)event{ // game main cycle // - moves hero, enemies etc here hero.x += 1; if (hero.x > 320) { [self gameOver]; } } -(void)gameOver{ // add the GameOver screen // - we remove the onEnterFrame event and show a background with a Reset button [self removeEventListener:@selector(onEnterFrame:) atObject:self forType:SP_EVENT_TYPE_ENTER_FRAME]; gameOverImage = [SPImage imageWithContentsOfFile:@"gameOverBkg.png"]; gameOverScreen = [SPSprite sprite]; [gameOverScreen addChild:gameOverImage]; [mContents addChild:gameOverScreen]; resetButton = [SPButton buttonWithUpState:[SPTexture textureWithContentsOfFile:@"back2menu.png"]]; [resetButton addEventListener:@selector(onResetButtonTriggered:) atObject:self forType:SP_EVENT_TYPE_TRIGGERED]; [gameOverScreen addChild:resetButton]; } -(void)onResetButtonTriggered:(SPEvent*)event{ // we go back to the main menu [self mainMenu]; } @end
I did not double checked what i wrote but it's very similar to how my game actually works so i hope that this could be a decent way to postpone the problem when we'll be more experienced.
If not please make me know!^^'
Edit: corrected some typos and mistakes but take it just as an aexample and not as a fully working code
