ios - optimize animation in cocos2d failed -



ios - optimize animation in cocos2d failed -

when didn't optimize animation,it worked well.but when optimized animation,the programme crashed.and xcode log said:

assertion failure in -[ccspritebatchnode addchild:z:tag:], /users/hanpengbo/documents/xcode/cocos2d_helloworld/cocos2d_helloworld/libs/coco‌​s2d/ccspritebatchnode.m:183

in ccspritebatchnode.m:183,there is

nsassert( child.texture.name == textureatlas_.texture.name, @"ccsprite not using same texture id");

here code

// cache ccspriteframecache *cache=[ccspriteframecache sharedspriteframecache]; [cache addspriteframeswithfile:@"birdatlas.plist"]; // frame array nsmutablearray *framesarray=[nsmutablearray array]; (int i=1; i<10; i++) { nsstring *framename=[nsstring stringwithformat:@"bird%d.png", i]; id frameobject=[cache spriteframebyname:framename]; [framesarray addobject:frameobject]; } // animation object id animobject=[ccanimation animationwithframes:framesarray delay:0.1]; // animation action id animaction=[ccanimate actionwithanimation:animobject restoreoriginalframe:no]; animaction=[ccrepeatforever actionwithaction:animaction]; // sprite cocosguy = [ccsprite spritewithfile: @"icon.png"];//cocosguy ccsprite,declared earler cocosguy.position = ccp( 200, 300 ); // batchnode ccspritebatchnode *batchnode=[ccspritebatchnode batchnodewithfile:@"birdatlas.png"]; [self addchild:batchnode]; [batchnode addchild:cocosguy]; [cocosguy runaction:animaction];

update: here corrected code,and works well

// batchnode ccspritebatchnode *batchnode=[ccspritebatchnode batchnodewithfile:@"birdatlas.png"]; [cocosguy settexture:[batchnode texture]]; [self addchild:batchnode]; [batchnode addchild:cocosguy];

for work, icon.png texture should in birdatlas.png texture, appropriate declaration in .plist. batchnodes 1) created 1 texture (and one), , 2) take children sprites same texture.

... , , dont know intent, typically have

ccsprite *cocosguy = [ccsprite spritewithspriteframe:[cache spriteframebyname:@"bird1.png"];

in case, think batch node add together work.

... , , not sure using batch node of consequence animation, if texture contains animation frames 1 animation. frames displayed 1 @ time, dont think benefit batched draw call.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
