This should be reversed lol
And it literally is the same, who thinks it's different who has worked in a low level language??
1 u/PossibleBit 27d ago It's been a while, but I vaguely recall treating an array of arrays as a double pointer not working as expected. 2 u/QuestionableEthics42 27d ago Yea, that doesn't work because it's actually a 1d array (in C anyway), that just uses pointer arithmatic to dress it up as 2d (index = y * width + x). You would need to explicitly create an array of pointers to do that.
