Several months ago there was a discussion
about implementing earlier dates for heliports, and making them more suitable for airships. I drew a mock-up at the time, worked on some tiles for a bit, then abandoned it.
The mooring mast is available from 1918 (earliest date I could find for erected masts) to 1960 (last year of operation for a commercial mast at an airport). The upper deck on the mast displays company colors.
Tonight I'm just going to put out there what I've done, and I'll let somebody else pick up any of the sprite or code development. I'm not putting this in the release thread for several reasons:
1) It's a bit of a hack. It replaces the single-tile heliport, but to make it look right with airships, the graphic overhangs another tile. If you're not careful, other graphics will lay over it and cause considerable glitches.
2) Alignment issues - there may not be a perfect "sweet spot" to put the mast in regards to the nose of the various airships.
3) Pixels lack proper shading, too lazy to fix it.
4) Not climate aware
5) Could use some more ground objects such as a nice period-appropriate building under the mast, maintenance buildings, maybe a windsock...
Anyhow, feel free to take this and adapt it to your needs. if you'd like to update it here, I'll be more than happy to edit this post to update to newer versions. Released under Public Domain, based on some code from RobC's heliport.
