Map Editor: borders howto

Text
: you can limit the number of combinations in the map creation algorithm, and in the settings allowed in your editor. : : I remember the tilesets of Civ3, it contained an incredible amound of tiles, and it still supported only limited combinations. : when you put a green on coast, a thin border of desert was inserted. the green tile was a green-to-desert, and the coast was desert-to-coast. there wasn't a desert-tile in between, just the transition green-coast was solved with green-(desert)-coast. : : you don't need a bunch of Ifs for that: : each tile can has 8 neighbors. : Imageine you have 4 different tiles, you can encode this in 2 bit. : this means 16bit to encode all possible combinations of 8 neighbors of 4 kinds. : yes this is much, but you can cut it down, e.g. by only using the 4 direct neighbors of a tile and by allowing only some neighbor combinations, like the example above. : : as another solution, some designers limit the number of combinations down by placing the transition in the middle of the tile. : this is a different approach and rather useful for AOE-style games than for CIV-style games. : : : the Source of C-Evo and a really detailed description of the Map format is also avaliable for download, if you want to dig yourself thru. : : brgds : Kaeru
