Autotile Update Script
Here is a little script I did a while ago. I think I posted it somewhere but Tsukihime had use for it and couldn't find it, and said here would be a good place for it... so!
Anyway it's a script that updates autotiles, properly setting them as if they were placed in the editor. I made it mostly for the random dungeon scripts I am working on, to make more varied terrain.
class Game_Map def update_all_autotiles for i in 0...width for j in 0...height update_autotile(i, j, 0) update_autotile(i, j, 1) end end end def autotile_edge(autotile, x, y, z) valid?(x, y) && autotile != autotile_type(x, y, z) end def autotile_wall_edge(autotile, x, y, z) if (autotile / 8) % 2 == 1 return false if autotile_type(x, y, z) + 8 == autotile end autotile_edge(autotile, x, y, z) end def update_autotile(x, y, z) autotile = autotile_type(x, y, z) return if autotile < 0 index = 0 case get_autotile_group(autotile) when 2 l = autotile_edge(autotile, x - 1, y, z) r = autotile_edge(autotile, x + 1, y, z) index = waterfall_autotile_index(l,r) when 1 l = autotile_wall_edge(autotile, x - 1, y, z) r = autotile_wall_edge(autotile, x + 1, y, z) u = autotile_edge(autotile, x, y - 1, z) d = autotile_edge(autotile, x, y + 1, z) index = wall_autotile_index(u,d,l,r) when 0 l = autotile_edge(autotile, x - 1, y, z) r = autotile_edge(autotile, x + 1, y, z) u = autotile_edge(autotile, x, y - 1, z) d = autotile_edge(autotile, x, y + 1, z) ul = autotile_edge(autotile, x - 1, y - 1, z) ur = autotile_edge(autotile, x + 1, y - 1, z) dl = autotile_edge(autotile, x - 1, y + 1, z) dr = autotile_edge(autotile, x + 1, y + 1, z) index = normal_autotile_index(u,d,l,r,ul,ur,dl,dr) end @map.data[x, y, z] = get_autotile_tile_id(autotile, index) end def get_autotile_tile_id(autotile, index) 2048 + (48 * autotile) + index end def get_autotile_group(autotile) return unless autotile return 2 if autotile == 5 or autotile == 7 or autotile == 9 or autotile == 11 or autotile == 13 or autotile == 15 return 1 if autotile >= 48 and autotile <= 79 return 1 if autotile >= 88 and autotile <= 95 return 1 if autotile >= 104 and autotile <= 111 return 1 if autotile >= 120 and autotile <= 127 return 0 end def waterfall_autotile_index(l,r) edge = 0 edge |= 1 if l edge |= 2 if r return edge end def wall_autotile_index(u,d,l,r) edge = 0 edge |= 1 if l edge |= 2 if u edge |= 4 if r edge |= 8 if d return edge end def normal_autotile_index(u,d,l,r,ul,ur,dl,dr) edge = 0 edge |= 1 if l edge |= 2 if u edge |= 4 if r edge |= 8 if d corner = 0 case edge when 0 corner |= 1 if ul corner |= 2 if ur corner |= 4 if dr corner |= 8 if dl return corner when 1 corner |= 1 if ur corner |= 2 if dr return 16 | corner when 2 corner |= 1 if dr corner |= 2 if dl return 20 | corner when 4 corner |= 1 if dl corner |= 2 if ul return 24 | corner when 8 corner |= 1 if ul corner |= 2 if ur return 28 | corner when 5 return 32 when 10 return 33 when 3 return dr ? 35 : 34 when 6 return dl ? 37 : 36 when 12 return ul ? 39 : 38 when 9 return ur ? 41 : 40 when 7 return 42 when 11 return 43 when 13 return 44 when 14 return 45 when 15 return 46 else return 47 end end end
