cocos2d iphone - Updating a CCTexture2D from a BatchNode -

-

after completed testing, have moved images on spritesheet.

i loaded batchnode appropriate files , images load fine.

but running issue of swapping textures out. when images individual files, there no problem. seems cctexture2d doesn’t sprite sheet.

i have objects stored in multidimensional array, can run through them , update image.

here did when worked: 

cctexture2d* tex = [[cctexturecache sharedtexturecache] addimage:@"alt-image.png"]; [((myfunobject*)[[myfunobject2darr objectatindex:j]objectatindex:i])->img settexture: tex];

here doing now:

cctexture2d* tex = [[cctexturecache sharedtexturecache] addimage:[ccsprite spritewithspriteframename:@"alt-image.png"]]; [((myfunobject*)[[myfunobject2darr objectatindex:j]objectatindex:i])->img settexture: tex];

myfunobject subclass of ccsprite , has ccsprite img property set. run through array , find objects , replace image new image “alt-image.png”.

seems simple, outside of sprite sheet worked flawlessly.

can tell me doing wrong?

update: here solution in future has issue

you can't change sprites 'texture' when texture in question spritesheet. (slapped head on one) can change rectangle viewed.

here how it:

[((myfunobject*)[[myfunobject2darr objectatindex:j]objectatindex:i])->img settexturerect:[[ccspriteframecache sharedspriteframecache] spriteframebyname: @"alt-image.png" ].rect];

notice changed settexture settexturerect, called spriteframe's rectangle argument.

enjoy.
