Heya
I’m still learning flash and actionscript 3 and i am having trouble with variable and object names. I need to be able to combine variable names together (in the same way as php can combine by doing var1.var2).
My swf contains 4 loaders (image1_loader, image2_loader etc…) which are a child of (image1_content, image2_content etc……)
I then have 4 buttons which load an image into the loader and while doing so they define the currently active loader.
Finally i have 4 control buttons - scale up/down and rotate clockwise/anticlockwise which should only control the currently active loader (as set by the buttons above)
So my buttons as well as loading the image have the event listener:
image1_btn.addEventListener(MouseEvent.CLICK, setCurrentSelection);
image2_btn.addEventListener(MouseEvent.CLICK, setCurrentSelection);
(and so on..)
function setCurrentSelection(e:MouseEvent):void {
if (e.currentTarget===image1_btn){activeLoader='image1';}
if (e.currentTarget===image2_btn){activeLoader='image2';}
if (e.currentTarget===image3_btn){activeLoader='image3';}
if (e.currentTarget===image4_btn){activeLoader='image4';}
}
So after setting my activeLoader as the string ‘imageX’ i have a control functions as in this rotate one:
rotateClock_btn.addEventListener(MouseEvent.MOUSE_DOWN, rotateClockwise);
rotateAnti_btn.addEventListener(MouseEvent.MOUSE_DOWN, rotateAntiClockwise);
function rotateClockwise(event:Event):void {
rotateAroundCenter(imageX_content, 10, ptR);
}
function rotateAntiClockwise(event:Event):void {
rotateAroundCenter(imageX_content, -10, ptR);
}
So within the rotateClockwise and rotateAntiClockwise functions i need to be able to recognise which is the currently active loader and have that number instead of the X - so if it is image1_loader - it needs to be image1_content, if 4 - image4_content…
I had tried to do it as this but it doesn’t like it being a string:
rotateAroundCenter((activeLoader+'_content'), 10, ptR);
Please could anyone help me understand how to solve (sorry if i havent explained it clearly!) and please go easy on me - i’m learning as i go myself
