Walls: Name format: name_X.arc, name_X.PDA.png 1 | 8 -+- 2 | 4 X is a bit-wise combination expressed in hexadecimal form. For example, 8 + 4 + 2 + 1 = F describes a vertical cross, and 4 + 1 = 5 identifies a vertical wall. P, D, and A are always 1. f diagonal connecting points are not offered by the arch. If d Object Names: When creating .arc files, the object name is determined by a similar, but distinctly different, scheme. See the server code in server/build_map.c and random_maps/wall.c for the source of the information that follows. The arch name (ie. awall) must not have any underscores. A suffix in the form _U[_V[_W]] is appended to the arch name. U is the number of connection points (ie. for a pillar U == 0, and for a cross U == 4). At the time of this writing, the formulae for calculating V and W is not known, but, U, V, and W can be determined as follows. Calculate a value called "connect" by adding the values of the connecting points: 4 | 1 -0- 2 | 8 Then use "connect" to pick a suffix: 0: _0 1: _1_3 2: _1_4 3: if (has_window) _win2 else _2_1_2 4: _1_2 5: _2_2_4 6: _2_2_1 7: _3_1 8: _1_1 9: _2_2_3 10: _2_2_2 11: _3_3 12: if (has_window) _win1 else _2_1_1 13: _3_4 14: _3_2 15: _4 For a complete example, a vertical cross wall graphic in an awall arch set is named awall_F.base.111.png. Face information is kept in awall_F.face, and the archetype data is in awall.arc. Inside awall.arc, the Object name is awall_4. Diagonal (extended) walls, roads, etc. The legacy wall-naming convention is used in conjunction with the extension to the name format described here to provide a uniform naming scheme that supports corner connections. Legacy names do not need to change to simply add diagonal versions of the legacy graphics. The name format is name_XY.arc, name_XY.PDA.png X follows the same rules as used for the legacy wall format, except that when there are no NSEW connecting points, X == 0. Y may be omitted, or may be 0 if diagonal connecting points are not offered by the arch. If diagonal connecting points are implemented, Y is a bit-wise combination computed in the same manner as X, and is also expressed as a hexadecimal digit. The difference is that it refers to corner connections: 1 2 \ / X / \ 8 4 For example, name_0F refers to a diagonal cross, or connecting points in all four corners. name_05 and name_0A refer to pure diagonals. Since diagonal pieces require corner fills, P is used to differentiate the component parts of the diagonal. P (part number) ranges from 1 to 3. 1 : used for "normal" pieces that connect direction points. 2 : used for a top corner fill needed to complete diagonal connections. 3 : used for a bottom corner fill needed to complete diagonal connections. Examples of diagonal files are dirtroad_05.211, dirtroad_05.311, dirtroad_0A.211, and dirtroad_0A.311. The archetypes for these are stored in dirtroad_05.arc and dirtroad_0A.arc. The corner fill is a "part" of a diagonal, and is not really useful on its own. The .211 and .311 file names are based on the full diagonal, but are used for all diagonal connecting points. Usually it is not necessary to customize the corner piece to fit each and every possible XY combinationi that incorporates a diagonal connecting point. Object Names: When creating object names, use a different format (_U_XYP) unless the legacy naming format can be figured out and adapted to the diagonal set - in which case, it should be documented here. This format allows consistent object naming in the event that renaming is desirable in the future, and it does not collide with the legacy object naming. U = Number of connecting points. XY = Where X and Y are re-used as described above. P = Where P is the part number. Cave: Complex River names: NOTE: Consider deprecation of this format in favor of the extended wall naming. It is more flexible than this format. Simple diagonals, like non-branched rivers, are saved as name_XY.arc and name_XY.PDA.png. X and Y use the direction scheme shown above (and copied here for ease of reference). For example, river_15 runs north/south; river_26 runs from the northeast to the southwest. 8 1 2 \ | / 7- 0 -3 / | \ 6 5 4 X and Y do not define direction of water flow. They are simply connecting points to neighboring arches of the same set. X and Y are ordered low to high, so it is not expected that a river_62 exist; instead the piece is named river_26. A cul-de-sac, or dead-end could have X == 0 and Y set to the connect point. Conceptually, a pool could follow this same naming convention and set X == Y == 0. D and A are presently always set to 1. P ranges from 1 to 3. 1 : used for "normal" pieces that connect direction points. 2 : used for a top corner wedge used to fill in diagonals (i.e. A wedge in the top right or top left corner). 3 : used for a bottom corner wedge used to fill in diagonals (i.e. A wedge in the bottom right or bottom left corner). Examples of wedges are river_48.211, river_48.311, river_26.211, and river_26.311. The archetypes for these are stored in river_48.arc and river_26.arc. The wedge is a "part" of a diagonal, and is not really useful on its own. River junctions, add another digit to the format used by simple diagonals, and are stored as name_XYZ.arc and name_XYZ.PDA. X, Y, and Z represent the three directions the river exits. 367 would be east,southwest, and west. Junctions, or branchesi, may also have multiple parts - this happens when the junction has a diagonal direction. By convention, directions for the river parts are in ascending order. That is, if the exit locations are 2, 6, 3, the name could be branch_236 (not branch_326, or branch_623, etc). Complex branching paths could be set by adding digits to allow four or more connecting points, but use of the extended walls format is recommended instead.
