My modifications to the TinyMARE engine
These are my modifications to the TinyMARE MUD engine. You can find the original source at https://www.winds.org/pub/tinymare/. The following changes have been made:
- Added secondary SQLite3 database engine, accessible in-game via the
@sqlcommand andsql()function - Addition of Perlin Noise functions from https://github.com/stegu/perlin-noise
The SQLite3 database is automatically connected at runtime, and is located at
run/db/sdb. It is accessible in-game to Wizards, and those granted the power
SQL (@empower user=SQL:Y) via the @sql command and the sql() function.
@sql SQL STATEMENT
The @sql command executes a SQLite statement and returns the result to the
player's console as a space-delimited table.
@sql SELECT * FROM foo
1 foo
2 bar
sql(SQL STATEMENT)
sql(SQL STATEMENT, COL DELIM)
sql(SQL STATEMENT, COL DELIM, ROW DELIM)
The sql() function executes a SQLite statement and returns the result. The
default format is a space-delimited table. The default column delimiter is a
space and the default row delimiter is a newline.
Making use of Stegu's public domain Noise library, it is now possible to generate noise in anywhere from one to four dimensions. This is immensely useful for very large areas of automatically generated terrain.
The Perlin Noise functions of the library were left unimplemented as they required double the parameters to use as the simpler noiseX() functions. If you require the true Perlin Noise functions either drop me a message or implement them yourself and submit a pull request. I simply left them out because they appeared to be more difficult to use and I didn't see a scenario where higher quality noise was required for a MUD.
noise1(x)
Returns a float value of noise for the 1-dimensional coordinate x.
noise2(x, y)
Returns a float value of noise for the 2-dimensional coordinates x,y.
noise3(x, y, z)
Returns a float value of noise for the 3-dimensional coordinates x,y,z.
noise4(x, y, z, h)
Returns a float value of noise for the 4-dimensional coordinates x,y,z,h.
