I am currently porting a game from version 2.1 to 3.2 of cocos2d. We have over 3600 pvr.gz files that are NOT flipped, eg were produced and working under 2.1. We tested out with TexturePacker the option to flipY for pvr images, and sure enough code and animations work fine.

Now, we can go and do this manually for all our files, but ... is there a way i could convince verions 3.2 to use the 'old' pvr rules. This is a port, all our assets have been produced already.

Alternately, any command-line utility/tool i could use and script recursively the pvr conversion in my Resources folder :)

any help greatly appreciated. tia.

  • Is that 3.2 from the website or github? I remember a discussion of a bug where textures were upside down in SpriteBuilder at one point (perhaps 2 months back) and that has been fixed. Maybe try v3.1 or the develop branch. If it's okay in 3.1 maybe you can undo the change made to 3.2. Otherwise try batch-processing with TP, it has a command-line tool so you needn't do this manually for each individual .tps file. – CodeSmile Sep 06 '14 at 15:27
  • github ... the cocos2d team made a decision to 'standardize' with other frameworks and roll out with flippedY pvr's ... possibly for the sake of SpriteBuilder (conjecture here). I have neither TP nor the .tps files, visual's people have that. I was trying to scramble under their nose :) to get the job done. Thks for the tip. – YvesLeBorg Sep 06 '14 at 15:56
  • @downvoter : if you explain why you did `downvote`, i can edit the question to make it better (as appropriate). – YvesLeBorg Aug 28 '15 at 15:15

ok, many thanks to Scott Lembcke of cocos2d for pointing me in the right direction. For posterity, hope this helps someone out there. PVRTexToolCLI did the job for me (from ImgTech.com). Free to download, free to use, you must register on their site.

here is the syntax (for this game's assets strategy)

PVRTexToolCLI -i old_magie_cleanse-hd.pvr -o magie_cleanse-hd.pvr -flip y,flag -f r8g8b8a8 -legacypvr

notes :

  • I am still using pvr v2 format, just because i like to go one change at a time. After I run my tests, i will switch all textures to pvr v3. Cocos2d 3.2 supports pvr v2 and pvr v3, but who knows for how long.
  • format is rgb8888 in our case, you will have to figure out the format of your own. You can use the PVRTextToolGUI and drag one of your existing textures into it to figure out the current encoding/compression.
  • If you have compressed textures, use "-q pvrtcbest" to prevent artefacts. Slow, hogs tons of CPU, but worth it.
