why store the cskin as a unique_ptr in unordered_map anyway? If it‘s just a cskin you can emplace and only the map allocates anything
Jupstar ✪ 2022-10-13 04:53:30Z
And what do you use as key?
04:53
You could overload the hash to work with cskin
04:57
Tho the hash might calculate before inserting takes place

deen 2022-10-13 06:49:15Z
fixed size array with a cstr of the name of skin.
Avatar
Jupstar ✪ 2022-10-13 06:56:52Z
But then the string must be a heap object
06:58
I think arrays doent have std hash support
06:58
But if u have time to implement what u mean do it, bcs reading code is easier xd
07:00
In the end it doesn't matter too much. If it creates two pointers plus cskin in heap vs cskin and a 24 bytes array

Can you delete IScrollBarScale's destructor and see if it still complains?

Tater 2022-10-13 19:49:12Z
sure but you can also store distance in that grid because
19:49
you start from the finish and then expand outwards by 1 tile at a time incrementing by one each pass
19:50
then you get a grid that has distance and you can do some checks to figure out where to go
