Hello,

I’ve got a problem on setTexture because when i put the application in background and resume it the texture becomes lines in place of staying like the original sprites.
Have you any ideas about how to fix it?

BEFORE / AFTER :

Thank you, Have a good day.

You generated texture by yourself, so you should reload them as engine did after OpenGL context lost.
You can refer CCTextureCache::addImage(), which caches file path, and HelloWorld/android/jni/helloworld/main.cpp, which reloads texture.

Thank you for your answer :smiley:

Hello,

I tried to use your tips, but i continue to have this error again.
The thing is in the main i’m using reloadAllTexture, and at the construction of my sprite i’m using CCTextureCache::addImage and setTexture on the sprite but after i don’t know what to do when i resume the game?

Thank you.

You should implement your own reloadAllTexture.

I’m a newby with cocos2dx and i prefer to show you some piece of code to determine what is wrong because i surely made some mistakes in my code :smiley:

Here is how i initialize my sprite:

CCTexture2D *texture = CCTextureCache::sharedTextureCache()->addImage(elem->getPath());

if (texture)
initWithTexture(texture);

ccTexParams tp = {GL_LINEAR, GL_LINEAR, GL_REPEAT, GL_REPEAT};
getTexture()->setTexParameters(&tp);

and the main which is reloaded OpenGl context and reloadTexture is the same as in helloWorld.

What can i do to get back my texture in reloadTexture?

Thank you, have a good day.
