Error with irr::core::array when it's in the heap.

[cederron]

Hello all,
I need to create an array in the heap and i use this code

Code: Select all

irr::core::array<rect<s32>> *IrrArray = new irr::core::array<rect<s32>>();
rect<s32> r= &IrrArray[0];

With this code I get the error:
error C2440: 'initializing' : cannot convert from 'irr::core::array<T> *' to 'irr::core::rect<T> '

However the same thing but in the stack works fine:

Code: Select all

array<rect<s32>> IrrArray;
rect<s32> r = IrrArray[0];

I thought it would work with the array in the heap, but it's not, maybe I'm not allocating the array correctly but I can't figure out whats going on.

Edit: well, I see it's trying to convert the array instead of the element in the array, but I don't know why

Two things...

First, the blocks of code you posted are not equivalent. It looks like you are confusing the address-of operator [&] with the dereferencing-star operator [*]. Your error is that you are taking the address of an array pointer and then indexing [which gets you an array pointer]. You would need to write (*IrrArray)[0] to get what you want.

Second, are you absolutely sure that you want to create a pointer to an array?

thank you vitek. I need to revise my c++ skills.
I need to use a pointer to an array because im using it inside a c++/cli class and i can only use a pointer there.

Thank you again.
