Round to the Nearest Value

Danwize — Thu, 04 Mar 2010 19:17:15 +0000

As I was developing a game I needed something to round an integer to the nearest 5. The following function allows you to round a given integer n to the nearest integer f. It’s a very simple Actionscript function, but I it might come in handy.


public function round(n:int, f:int):int
{
     return Math.round(n/f)*f;
}

Missing Text in Flash Player

PROBLEM: Some text won’t show up in Flash-player on Mac OSX.

I was just on a tech support call with a customer who was using the Visual Link Spanish Personal Proficiency Trainer (PPT), a Flash-player based language learning program. She recently upgraded her Mac to Snow Leopard. Wherever text was supposed to appear in the PPT, there was nothing. When she went to Adobe’s about flash player site the version information text didn’t show up either.

SOLUTION: Remove duplicate fonts from Users/Library/Fonts.

After trying all the usual solutions like reinstalling Flash-player, restarting the browser and restarting the computer nothing worked. Still no text appeared, so I turned to Google. I was not the first to have this problem. In an apple forum I found a discussion about a similar problem with various Flash-player applications. To solve the problem, all you have to do is delete the fonts from Users/Library/Fonts that are duplicated in HD/Library/Fonts. Problem Solved!

Deep Linking

I just happened across this cool feature in Flex while looking for solutions to other problems. It’s called deep linking. It allows you to return to a specific state of a Flex application by including information in the url. Go here to read more about it: http://cookbooks.adobe.com/post_Deep_Linking_in_Flex-9563.html

Are you tired of seeing the yellow focus rectangle in your Flex applications? It’s really easy to get rid of it. All you have to do is this:
stage.setFocusRect = false;
It’s really that easy. See more info about this property here: http://livedocs.adobe.com/flex/3/langref/flash/display/Stage.html#stageFocusRect

AS3 Binary Search

Danwize — Tue, 13 Oct 2009 17:04:45 +0000

Here is a simple recursive binary search function written in AS3. This is a quick and efficient way to search an array. In the worst case, binary search will take log₂(n) steps to finish the search where n is the length of the array. Of course this algorithm only works if the array has been sorted. It returns the index of the item you search for.


protected function binarySearch(array:Array, value:String,
     left:int, right:int):int

{
     if(left > right)
          return -1;
     var middle:int = (left + right) / 2;
     if(array[middle] == value)
          return middle;
     else if(array[middle] > value)
          return binarySearch(array, value, left,
               middle - 1);
     else
          return binarySearch(array, value, middle + 1,
               right);
}

Here’s how to use it:

binarySearch(arrayOfStrings, "myArrayItem", 0,
     arrayOfStrings.length);

You’ll get back the array index of the item you were searching for. If it is not found, the function returns -1.

Parable of the Laborers in the Vineyard

The Laborers in the Vineyard (vs 1-16)

This parable is just one more example of the beautiful symbolism the Savior uses to teach about His atonement. After telling the rich young man that he must sell all he hath and give to the poor in the previous chapter, the following exchange takes place:

24 And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a ^arich man to enter into the kingdom of God.

25 When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved?

26 ^aBut Jesus beheld them, and said unto them, With men this is impossible; but with God all things are ^bpossible.

27 ¶ Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore?

28 And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the ^aregeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, ^bjudging the twelve tribes of Israel.

29 And every one that hath ^aforsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my ^bname’s sake, shall receive an hundredfold, and shall inherit ^ceverlasting life.

In a gentle rebuke to Peter, the Savior tells the parable of the Laborers in the Vineyard. Peter may have mistakenly felt that because if his status and work as an apostle of the Lord, he was entitled to something more than others who may have entered the fold later in there lives and may not have done as many great works as he had.

What a great comfort and joy it is to know that through the Saviors atonement, all things are possible. Even the vilest sinner that begins to labor in the Lord’s work will receive the same reward as those who have labored all their lives for the Lord. The Lord has promised eternal life to all who repent and come unto Him!! By the Grace of God this is possible.

Hello world!
