The simplicity of creating a custom cursor within Flash is a task that will surely be used time after time again. Well, as for creating a custom cursor using AS3, the syntax used is identical as written in AS2.
Create a Custom Cursor
You can easily create a custom cursor just as would in AS2. The syntax goes as so:
//Hide mouse Mouse.hide(); //Replace hidden mouse with cursor mc customCursor.startDrag(true);
I hope this helps in your migration over into AS3. If there is something in particular you want to add or see with the Moving From AS2 to AS3 series, feel free to contact me via the contact page.
