[iOS] Tighten Letter Spacing

[iOS] Jumping into iphone game development

If your character image is too big to catch a collision, you may need to make hidden rectangle for the jump action. When the jump action is called, it will move both of the actual image and collisionRect frame. Collision method only check the collision between hws and collisionRect.

- (void) fall
{
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.8];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(animateRunning)];
    characterImage.frame = CGRectMake(characterImage.frame.origin.x, 90 +30, 175, 181);
    collisionRect.frame = CGRectMake(collisionRect.frame.origin.x, 90 +90, 26, 111);
    [UIView commitAnimations];
}

- (IBAction) jump
{
    [characterImage setAnimationImages:jumpAni];
    [characterImage setAnimationDuration:1];
    [characterImage setAnimationRepeatCount:1];
    [characterImage startAnimating];
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(fall)];
    collisionRect.frame = CGRectMake(collisionRect.frame.origin.x, 90 -90, 26, 111);
    
    characterImage.frame = CGRectMake(characterImage.frame.origin.x, 90 -30, 175, 181);
    [UIView commitAnimations];
    [characterImage startAnimating];

}

[iOS] AVAudioPlayer delay first play

If your application's effect sounds is played a little late than actual action, you may need to load the sound file on the viewDidLoad for prepare to play.

Example code is below.

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self setupArray];
    [self imgAlloc];
    courseNameField.text = courseName;
    
    NSString *backgroundSoundpath = [NSString stringWithFormat:@"%@%@", [[NSBundle mainBundle] resourcePath], @"/ahhh.mp3"];
    NSError *err00;
    ahhhPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: [NSURL fileURLWithPath:backgroundSoundpath] error:&err00];
    ahhhPlayer.currentTime = 0;
    [ahhhPlayer prepareToPlay];
    
    NSString *whoopiepath = [NSString stringWithFormat:@"%@%@", [[NSBundle mainBundle] resourcePath], @"/whoopie.wav"];
    NSError *err01;
    whoopiePlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: [NSURL fileURLWithPath:whoopiepath] error:&err01];
    whoopiePlayer.currentTime = 0;
    [whoopiePlayer prepareToPlay];
    
    NSString *jumppath = [NSString stringWithFormat:@"%@%@", [[NSBundle mainBundle] resourcePath], @"/WhoopFlp.wav"];
    NSError *err02;
    jumpPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: [NSURL fileURLWithPath:jumppath] error:&err02];
    jumpPlayer.currentTime = 0;
    
    gameTimer = [NSTimer scheduledTimerWithTimeInterval:.01 target:self selector:@selector(gameUpdate) userInfo:nil repeats:YES];
    
    [self animateRunning];
    [self backgroundSound];
    
}

[iOS] Before Flipside View get input value from pop-up pane

Before game start, UIAlertView will pop-up to get course name, then pass the value to next page for display and start game on Flipside view.

- (IBAction)showInfo:(id)sender
{
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Welcome!!" message:@"Enter your course name:"
                                                    delegate:self cancelButtonTitle:@"Continue" otherButtonTitles:nil];
    alert.alertViewStyle = UIAlertViewStylePlainTextInput;
    UITextField * alertTextField = [alert textFieldAtIndex:0];
    alertTextField.keyboardType = UIKeyboardTypeDefault;
    alertTextField.placeholder = @"Enter your course name";
    [alert show];
}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSString *buttonTitle=[alertView buttonTitleAtIndex:buttonIndex];
    if ([buttonTitle isEqualToString:@"Continue"]) {
        UITextField *textField = [alertView textFieldAtIndex:0];
        FlipsideViewController *controller = [[FlipsideViewController alloc]
                                              initWithNibName:@"FlipsideViewController" bundle:nil];
        controller.delegate = self;
        controller.courseName = textField.text;
        controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
        [self presentViewController:controller animated:YES completion:nil];
    }
}
