That is very common in many computer languages since the index of an array is an offset relative to start: zero-based numberingGarryG wrote: 21 Sep 2023 00:41 What I have discovered almost all numbering starts at 0 (zero).
For instance the sprite image of the single tile about .. from the left corner to center is 32 but have to show 31 in coding.
So the first element has index zero, then the second one has index one, since it is one off relative to the first one, and so one.
Also happens with the industry and cargo IDs, where you have 64 cargoes, but IDs from 0 to 63
But that still does not answer my question on the height of a tile, since in the picture provided, there were just 15+1+15 = 31 pixel in height and it does not matter for that question if they are indexed as 0..30 or 1..31 since in five bit 11111 there would still be one number (either 0 or 31) unused?!?
