@2x graphics.newImageSheet

Solar2D General Questions/Discussion

Hi you all, 

I tried to follow the tutorial that can be found at http://developer.coronalabs.com/forum/2010/12/08/dynamic-retina-spritesheets-heres-how, but in my game I’m using the graphics.newImageSheet  API instead of the  sprite.newSpriteSheet API. Furthermore, the  display.contentScaleX value changes as the phone’s resolution differs, so I cannot use this API if I want my game to run on various devices.

So could I know the right way to use @2x imageSheet?

The code I’m actually using is:

sheetRoma[1] = graphics.newImageSheet( "immagini/sfondoROMA/fiammaEfa.png", { width=36, height=17, numFrames=2 } ) roma[7] = display.newSprite( sheetRoma[1], { name="fiammaEfa2", start=1, count=2, time=velocitaFiammaEfa1 } ) roma[7].timeScale = 1.0 roma[7].x = roma[6].x - 154/2 roma[7].y = roma[6].y+20/2 roma[7].xScale = -0.6 roma[7].yScale = 0.6 roma[7].alpha = 0 roma[7]:play() roma[7].myName = "fiammaEfa2" roma[7].isFixedRotation=true roma[7].isSleepingAllowed = false

Thanks a lot

Hi @estiennelorenzo,

I can help with a few issues here:

  1. First, please read the guide on image sheets, especially the section “Dynamically-Selected Image Sheets”. This shows how to use image sheets for dynamic content scaling.

http://docs.coronalabs.com/guide/media/imageSheets/index.html

  1. If using physics, you should not scale objects using “.xScale”, “.yScale”, or “:scale()”. These do not adapt nicely to physical objects, because the image will scale in size, but the internal physical body will not.

Hope this helps,

Brent
