[Xerte] setScale()

[Julian Tenney]

If I'm understanding correctly, you want to keep the image in the centre
of the screen as it scales, right? The top right corner of the image
needs to move., so if you're doing this in an onEnterFrame:

 

img.setScale(scale--); //scale defined at 100 before the event is fired

 

img._x = 400 - img._width / 2; //keep it centred where the centre is at
400, 247

img._y = 247 - img._height / 2;

Can't reposition the image as it's centred on the page and needs to be
shown reducing in size...?

No, the origin is at 0,0. You need to also reposition the image.

Hi guys, 

 

When I use the setScale() function in Xerte to reduce the size of an
image it scales as if someone is dragging the bottom right of the image
to scale it. Is there any way of making it shrink in proportion with a
tween?
