I came across an article that employs CCPointer
I wanted to know if there are any tutorials on CCPointer. I am familiar with C++11 smart pointers however I could not find anything regarding CCPointer. Any tips on this would be helpful.
which article? I’m not familiar wIth CCPointer
. Cocos2d-x v3 uses Ref
and RefPtr
Yeah… that seems to be based on v2.x.
What version are you using ? v3 ?
If so, you should know Nodes and other objects are subclass of Ref
, which is a Reference count basically.
If you want to use those objects in vectors and others, you should use cocos2d container classes like:
cocos2d::Vector<>
, cocos2d::Map<>
, etc.
But if you want to use STL containers with cocos2d Ref
objects, you should wrap them in a RefPtr
object.
Yes I am using Vesrion 3.0. I did not know about
But if you want to use STL containers with cocos2d Ref objects, you should wrap them in a RefPtr object.
I was not aware of that. Can you give an example of how I could create a RefPtr
that points to a sprite pointer ?
I’ve tested this code, but it should work:
// create the shared data pointer
RefPtr<Sprite> ref(Sprite::create("hello.png"));
// add it to your std vector
_vector.push_back(ref);
See the RefPtrTest.cpp in cocos2d-x for a working sample
thank you for the example
