将CCPoint添加到CCArray

Question

I'm looking to call up a random CCPoint from CCArray , and then remove that point from the array so that it's not called up again. This is the code I used:

    myArray->addObject(pos1);

Where pos1 is a CCPoint and myArray is a CCArray . When I write that line, it brings up an error that reads: "No viable conversion from cocos2d::CCPoint to cocos2d::CCObject *". I know this means that CCPoint doesn't inherit from CCObject , but just making it inherit CCObject doesn't help the problem. I've also tried typecasting pos1 as well but that doesn't work either. What do you suggest I do so that I can keep an array of points? Thanks in advance.

@Shiva Kumar Ganthi comments with C-arrays are all good, but I think that using std::vector would be better. The main improvement would be the fact, that you can always check how many elements a vector has, and you don't have to worry about setting a used element to NULL and then checking for it when you take another random position (which can prove dangerous with big arrays that have a lot of NULL s).

Also learning about standard containers is also beneficial.

Oh, on a side note : you don't have to use CCPoint * , CCPoint is just fine.
