    <p>i'm making the final part of my game where it tells you what your score is. I wanted to make it flash, dynamic and animated, so i want the score to sort of total up, which i plan to do by making the text displayed by the score closer to the actual score in each draw event, until it reaches the total score.</p> <p>However, i want the digits of the score to flash as they increment, and then fade. I plan to do this by extracting the last digit from the score that was displayed one step away, and then comparing it to the last digit from the score that is currently displayed. Then, if they are different, i will set the color of the last digit from white to orange. This will happen for every digit.</p> <p>But then i want the digits to fade back down to white again, so what i need help with (i've looked everywhere and can't find answer) is i need to get the color of every letter, and then merge it into white. but i don't know how to get the red, green and blue components. here's what i've got so far:</p> <pre><code>-(BOOL) colourCount:(CCLabelBMFont*)label currentNo:(int)cNo targetNo:(int)tNo { CCArray *characters = [label children]; //-------The code for making certain letters orange will go here---------- //below makes the color of every letter more white for (int i=0; i++; i&lt;[characters count]) { [(CCSprite *)[characters objectAtIndex:[characters count]-i] setColor: [self mergeFont: [(CCSprite *)[characters objectAtIndex:[characters count]] color] ] ]; } } </code></pre> <p>and then i need a function called mergeFont that takes an input of a color, makes it more white, and then returns that color. I'm not even sure what a color is stored as though - is it an int?</p> <p>thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
