Preparations:
Create a new flash file (ActionScript 2.0) and save it as test.fla in this case.
Step 1:
Draw an arrow on the Stage.
Step 2:
Convert the arrow into a movieclip Symbol with instance name my_mc. Double-click on my_mc and centralize the arrow to the Stage.
Step 3:
Create a layer on top of the object layer and name it as actions.
Step 4:
Right-click on the frame and select Actions to open up the Actions panel.
Step 5:
Insert these codes inside the Actions panel.
That's all!
| function detectDirection(item) { var dx = item._x-_xmouse; var dy = item._y-_ymouse; var angle = Math.atan2(dy, dx); item._rotation = angle/Math.PI*180-90; } _root.onEnterFrame=function(){ detectDirection(my_mc); } |
