CCArray addobject with NULL

cocos2d-x C++
#1

is there any possible that i can add null to CCArray? i check the CCArray source code, there is an assert line, that i can’t do that. but i want to create a container to hold my object inherits from CCObject, and in the init function, i want to create the container with some defalut value like null just for placeholder.is it possible?

#2

in objetive-c(cocos2d) i can add object to an ccarray like this: [CCArray addObject:[NSNull null]]; how can i do that in cocos2d-x?

#3

to add an empty ccobject is not a valid option for you?

#4

thanks, i’m really not familiar with c++, can you show me how to create an empty ccobject?

#5

Why don’t you create an empty CCArray?

CCArray* array = CCArray::create();

But my suggestion is you’d better use std::vector or std::map.

#6

in fact i want to add a null object to a ccarray, but ccarray can’t do that

No, cocos2d-x does not allow adding NULL objects to it. you could create an Object that you would consider as “NULL”. Say, a CCNode object with a flag called isValidObject or something.
