Hello, Thanks for the answer, I want to be sure before going deeper. I look how this isometric projection works and now, I understand why there is this strang values. Maybe I can try to add an explanation somewhere for the next generation of developers.
I agree with you. This representation should be an internal one and we not have to worry about it, and I am sure the elders made a good job. Perhaps, it's not enough encapsulated, mostly in test where getTile with x and y is much used. Seb Le mar. 8 janv. 2019 à 22:57, Michael T.
