I have a HellpWorld template.
i have a CCNode with a variable:

Code:

CCSprite *a;//in header

with an init function

Code:

a=[CCSprite spriteWithFile:"a.png"];

added the CCNode as child in helloworld.m init

if i want to replace the image with another one using always a.
i have a method inside the CCNode that makes:

Code:

a=[CCSprite spriteWithFile:"b.png"];

but nothing happens...

Code:

[a release];

a=[CCSprite spriteWithFile:"b.png"];

make it crash...
so i've tryed:

Code:

[a setTexture: [[CCTexture2D alloc] initWithImage:[UIImage imageNamed: @"b.png"]];

and it works, but i think it will have memory leaks because i have used alloc. correct me if i'm wrong.

but i don't know how to release the texture before loading another.
and why:

Code:

a=[CCSprite spriteWithFile:"b.png"]

doesnt work?
thanks

the CCTextureCache handles the management of releasing and allocating textures.
