i would like to perform an animation on label text.i need to show 10 on label. the label should display first start with 0 then 1 ,2 ,3....end with 10.
example : showing display number animation is seems like in slot wheel.
how should i achieve that? is it any trick in cocos 2d?
Has anybody got a clue how to do that ?
First setup the label as an instance variable.
// In your .h
CCTabelTTF *_myLabeL;
Then (assuming you have already added it in your project) create an update method for it
- (void)updateLabel {
int currentVal = [_myLabel intValue];
NSString *newString;
currentVal += 1;
newString = [NSString stringWithFormat:@"%i", currentVal];
[_myLabel setString:newString];
}
Now we can create a method to call your update:
- (void)startUpdatingLabel:(int)newValue {
int curVal = [_myLabel intValue];
int difference = newValue-curVal;
for(int i=0; i > difference; i++) {
[self performSelector:@select(updateLabel) withObject:nil afterDelay:1.0];
}
}
Then all you have to do whenever you want to update the label (say to 10) is to call
[self startUpdatingLabel:10];
and it will update your label by 1 every 1 second until it reaches the new value
