Using scaling to bypass Apple minimum requirements

Solar2D General Questions/Discussion
#1

Hi guys,

One question :slight_smile:

For .png smallest game character images we should follow Apple 40by40px minimum requirement, so user can touch it without problems.

So @2x.png is 80by80px, and @4x.png is 160by160px minimum.

I want some images to be smaller than 40by40px.

I have noticed that when I use xScale and yScale on 40by40px image, its rectangle in physics “debug” mode stays the same size (it looks like that - I am not sure).

Can I solve things that way (by using xScale and yScale), instead of using bigger transparent background around image smaller than 40by40px?

Waiting your reply.

Many thanks!  :slight_smile:

You can’t scale physics bodies, however you can do custom shapes to make your own bigger area. However, I don’t think you need to do this. You want your touch target to be at least 40x40 which means adding transparency around your smaller object.  This will require you to do a custom shape so that physics affects the actual shape of your object and use the transparency as the larger touch target.
