Isometric…

I really need to stop playing with isometrics, more addictive than lego. Anyway made this from boredom.

Can you guess what it is? Post a comment if you know…

Truncating numbers in actionscript…

Published on November 13, 2008 in Flash, Math and Source Code. 12 Comments

So there’s no built in method to truncate a number in actionscript. Well a bit of playing around and a simple work around is just as good.

As most of you will know String’s can be truncated via substr();.

Well just typecast your value to be truncated to a String, call the substr(), using the length of the string minus your amount of digits to trincated, then typecast it back to a Number.

Code:

function truncate(val:String,truncCount:uint):String
{
	return val.substr(0,val.length-truncCount);
}

To use:

var num:Number = 56.673856;
trace(num)//56.673856
num = Number(truncate(num.toString(),5));
trace(num)//56.6

More Isometrics

Playing around with isometrics, perlin noise and sine waves. Something I have wanted to do for a while.

Anyway first app uses perlin noise for height or y pos depending if floating or not, click to toggle floating and randomise the x and y offset’s for the perlin noise.

The second app is using a simple sine wave accross a grid, well the first isometric block is using a sine, the rest just of the blocks just set their height or y pos to the one before it, again click to toggle floating.
