If you make the view size and the port size the same it will be just fine.
Yes, I am drawing it as a 64x64 from its beginning, it is not an enlargement to scale, it is a 64x64 drawing with a 4x4 brush that simulates 1 pixel of 16x16.Are you drawing it as a 64x64?
I am really new to gamemaker, I am 1 month old, and I did not understand what you mean.The issue that you have is either in the draw event somewhere or in the views settings.
Somewhere there is some sort of division, that changes the resolution of the tiles and that messes up the visualisation.
OK, I may be wrong, but what I see is scaling.I am really new to gamemaker, I am 1 month old, and I did not understand what you mean
