Drawing an arc (a segment of a circle’s circumference) is very similar to drawing a complete circle. Just like drawing a circle, drawing an arc requires you to specify the center, the radius, and the number of steps to take from the first point to the last. But drawing an arc also requires additional information such as the angle of the first point on the arc, the direction (clockwise or counter-clockwise) to travel around the circle’s circumference, and the angle of the last point on the arc. …

Unlike most other easing equations or functions, my easing functions are 0 to 1 based (like the “Math.random” function). This makes it easier to isolate the concept of “easing” from the concept of “tweening”. Tweening is responsible for creating a series of equidistant values between an initial state and a final state. Easing is responsible for shifting those values so they are no longer equally spaced.

There are times when you may want to weight a single random value to favor one number over another. For example, you may want a random number between 0 and 100 but you would prefer a number closer to 0 than to 100. In this situation, there is no need for a “tween” as you are only generating one number and there is nothing to go be”tween”. This is where easing functions which have been isolated from their tweening counterparts can come in handy.

Here are my most frequently used easing functions: …

Limiting or constraining a number to a specified range of values isn’t the most common task you’ll have to perform in Flash, but it does pop up from time to time. If you encounter such a situation here is a little bit of code for your consideration: …

A while ago, I wrote a Color Fading tutorial for ActionScript.org which provided nearly all the functions you’d ever want for fading colors. Did you notice that I said “nearly”? Well, today I’ve added yet another weapon to my color-fading code arsenal called “fadeHex”. The name probably won’t put fear in the hearts of fellow code warriors but it’s a powerful tool none the less. In essence, it lets you specify two colors, then creates a color gradient from the first color to the second and lets you choose a color at any point on that gradient. …
