Scaling down to SD as opposed to scaling up

Solar2D General Questions/Discussion
#1

Hi all,
I’m wondering if there is a best practice way of being able to scale images down to SD level as opposed to having everything work in SD and then scaling up for retina displays. It seems like retina displays are becoming the norm so I started my game in HD for iPad resolution but want to maintain backward compatibility with iPhone 3GS and earlier.

I tried changing the

 imageSuffix = {  
 ["@2x"] = 2,  
 }

to

 imageSuffix = {  
 ["@2x"] = .5,  
 }

and that pretty much works but is there I should be worried about or I should keep in mind continuing like this? [import]uid: 112953 topic_id: 24221 reply_id: 324221[/import]

When I was playing with dynamic scaling I found I had to do something like

imageSuffix = {  
 ["@2x"] = .5,  
 [""] = 1,  
 }

To keep from using low-res assets when I didn’t want to. It felt a bit hacky, like it worked but maybe isn’t supposed to. I don’t know – Corona keeps me paranoid if nothing else. [import]uid: 44647 topic_id: 24221 reply_id: 97848[/import]
