Bubbling under: Wanted: Canal

[cazfi]

This is not yet required for freeciv proper, but maybe some day. It would be nice to have the gfx. Custom ruleset "variant2" already would need this.

Canal is like type of river, but human made, and passable by ships.

I've thought about this in the past, but a 'blue road' doesn't really cut it. Maybe a honeycomb like design(except when it's only from one direction or passing straight through the tile?) with a few crosshatches to represent locks? Also, this would need to be drawn over irrigation(and farmland), and still look good when both are present.

Though on the code side, you'd have to prevent off-road (off-river/canal?) jumping from road to city/native terrain that is not directly connected.

First version done:
Connects with 4 Cardinal Directions
Does not connect to rivers (Might see how viable this is in the future)
Has ocean outlets
Runs alongside roads and railroads

I just tested the images as a direct replacement for rivers.

Another version, which is modified to connect to rivers. 2.6 supports differing road types connecting, correct? This would allow it to be like railroads over roads, but still with the canal attaching to the river on surrounding tiles.(Hopefully)

Thanks. I've now created initial version of a tileset called "Deltasquare" that is meant to be used with Variant2 ruleset on square (not hex) based maps, and this canal gfx is there. The tileset is available for S2_6 and TRUNK with modpack installer, and it's maintained in https://github.com/cazfi/fcmodpacks
