I am very interested in applying the warp/deform effect seen in the iPhone app Wobble (it lets you define regions on a raster image and then deforms those regions as it gets input from the accelerometer or the user’s touch as if they had adopted faux soft-body physics) to a game I am making, but I’m not sure how this effect was achieved. Anyone have any advice as to how I might program an analogous effect using Corona?
As we regroup after shipping the latest Corona, we are going to prioritize features, etc and publish a road map of some sort to let you all know what features are coming up next.

thinking of doing something like this using the sprite capability of corona, ie treat my image as a load of 2pix sprites stacked on top of each other, then wobble the individual sprites to make the image appear to wobble - will post code. [import]uid: 74338 topic_id: 2091 reply_id: 97187[/import]
and off course this can be easily be extended to
wobbling along the y axis by using vertical stripes,
and beyond into both horizontal and vertical
deforms by taking snaphots warping those.
in theory then it may be possible to create a full pseudo
3d texture mapped polygon environment with corona by
applying the deforms, snapshotting and saving to file.
Can I encourage you to put this on the code exchange? It is SUPERB and others, I am sure, would love to see it [import]uid: 52491 topic_id: 2091 reply_id: 100759[/import]
Open768, thank you, but the file is no longer available.
Could you please reupload it or put this on the code exchange? [import]uid: 136829 topic_id: 2091 reply_id: 108234[/import]
@jacksparrow.greg simples download the lib-wobbler, and dependent libraries from the githug, give it an image and off you go.
Then improve it and post it back.
– the hard work begins here
local oWobbler1 = cWobbler:create(“myimage”, width,height)
utility:moveToScreenCentre(oWobbler1.group)
oWobbler1.delay =20

Hi, open768!
How would you realize image skew by x and y axis (both directions)? I tried to make image skew by x axis by (xSkew - ySkew) angle and rotate group with sprites by ySkew. But I got image irtifact due to rotation. [import]uid: 153428 topic_id: 2091 reply_id: 115289[/import]
havent tried this but I would do one skew first (say x axis) , do a snapshot, save the image, load the new snaphot as vertical strips and skew them.
Could give some fun results but obviously this will suck performance if you do this in-process. rather prepare your animation ahead of time and load the frames of the skew animation as a spritesheet.
if I find the time in-between coding and marketing my up and coming game I’ll knock out an example. [import]uid: 74338 topic_id: 2091 reply_id: 115427[/import]

for the complement.
