Custom Trailing Cursor in Flash MX
Author: Siddharth
Create an Interval
Now, select the first frame of the Movie and open up the Actions Pane. Write the following:
setInterval(function()
{
_root.mouseX=_root._xmouse;
_root.mouseY=_root._ymouse;
},100);
Explanation
What the above code does is it sets an Interval as long as 100 milliseconds.
- A function is declared inside the interval which stores the X and Y positions of the cursor to two variables mouseX and mouseY. This function is called every 100 milliseconds.
_xmouse and _ymouse are two built-in properties through which we can get the position of the mouse pointer.
- 100 milliseconds is the time interval for which the two variables mouseX and mouseY will preserve the values of the cursor's X and Y positions as trapped by the recent call to the function.
- These values will be compared with the current X and Y positions of the mouse pointer. If the difference is not equal to 0 it will indicate that the mouse has moved.
This will become clear in the next step.
