I have found a way to make a seaplane airport available in trunk and buildable in seas or lakes!
It took some work editing some existing GRF's (mainly the small airport tiles in the Total Town Replacement set) and using some NewObject watertiles to keep the sea out of the airport and I'll admit it's not very pretty yet, but it works. I don't know what settings I have to change in the NFO so that it will only accept seaplanes, so for the time being all planes can land there. See picture below for screenshot. I'll post pictures of how I built it in the next post.

Airplane artists start drawing seaplanes!!!!

I am not sure about copyrights and so on, so I wont put the GRF up yet, can someone advise on what path I should follow to make sure I dont break any copyright rules?

UPDATE: Made a GRF, with a totally stripped airport, ideas for graphics are very welcome! Read grf description on how to build, or read this thread.

UPDATE: V1.1 released, without windsock (parameter will put it back)

UPDATE: The grf can be found here: http://www.tt-forums.net/viewtopic.php? ... 8#p1037438

In this post I will explain what I have done.

I have edited all the small airporttiles from the Total Town Replacement set so that they look like watertiles (all animated), also the inside of the hangar is water now. I've drawn some simple docks for the airplanes to load on and off.
I have also used a parameter in the Combined Airport Set GRF to make the fences disappear.

I have used SAC's newobjects GRF to make the keyside look more modern.

And finally I have found a GRF somewhere in the Forum that let's you place watertiles as New-Objects. This is the key to success, these tiles keep the water out. So, if you want you could build this airport in the middle of the ocean.

And that's all!

Looking for the *like* button... Very cool

Thank you!

The key element here is the watertile NewObjec that keeps the airport from flooding, it can be found here:

I dont really have the knowledge to code and draw a GRF that only replaces the small airport (as I stated before, I've edited the Total Town replacement GRF, so all the other changes are there too), I hope someone can pick this idea up and make it into a pretty (even though it is very wet) airport

I guess on could code an additional small-water-airport.

Nice approach though. I like these out of the box solutions that make things posibble that aren't really possible

Huh. That's really interesting. Good job!

"Like" is so 2008. +1

I consider it ugly and weird looking, but I have to say that the idea and realization is awesome

Nice. The hangar looks like there's a palette mis-match though.

There currently are no means via NewGRF to forbid other planes than sea planes to land on those airports. That part of the specs simply does not yet exist.

Concerning licenses:
- (Re-)using parts of the TTRS is mostly no issue. You have to credit the artists whose sprites you use. Checkout the credits and possibly its discussion thread for more detailed information.
- Combined airport set: No idea. Check out its license and / or ask the author(s) and artist(s) for permission to re-use the sprites
- SAC's NewObjects: same as above: ask her

You can totally skip and remove the NewObject part. Building rivers or canals at sea level has the very same effect. No NewGRF part or addition is needed for that.

Won't canals, at least, put a brick wall around the airport?

Canals indeed do that.

But you would get a wall around your seaplane airport, which doesn't look as good.

Hm, yes, you're right, they would. I only thought of them not showing in the middle of water - which in this case would not be the place, though it should be visibly. Thus I redact that quoted statement

I know it's not pretty But I couldn't resist posting this solution.

If anyone has some prettier sprites lying around I'll be happy to try and use them.

Nice. The hangar looks like there's a palette mis-match though.

If you mean the blue color, that is because my company colors were blue. It can change color.

Well thats not too bad, just be careful what planes get to land there then.

Thanks for the tip, I'll look into that. I'll try to filter out the code for changing the looks of airfields first from the original TTRS code, so it can be separate from that GRF. These are my first babysteps into coding and I'm still figuring out how NFO coding works, but I'm getting there

- Combined airport set: No idea. Check out its license and / or ask the author(s) and artist(s) for permission to re-use the sprites

I didn't use any graphics from that. I only use the parameter that they have, so you can turn the fences off around airfields. I'll look into finding only that piece of code.

- SAC's NewObjects: same as above: ask her

Also, didn't use any graphics from that, only parameter setting for prettier edges. Is not really needed for this to work, but I think it looks better than the stone edges.

Well as I saw in some later posts from you that you found out that you do need them to get a correct look. Rivers and canals do place an ugly stone border. I'll try and filter out the code for just that one tile from the newobjectGRF.

I'll try to contact all of the authors and artists of code and graphics I altered and try to make a nice little GRF out of that.

Maybe a bit late, but you could consider skipping NFO altogether and dive into NML instead. OpenGFX+Airports may give you inspiration on how to add an additional airport (based on one of the existing airports) instead of replacing them.

Hmmm, might be interesting. Will take some time though to figure that out too, but it looks a bit more human friendly

Quast65 wrote:but it looks a bit more human friendly

Exactly why I'm suggesting to use it instead

I have done some work Totally stripped the airport, fences are gone via parameter (sadly this applies to all airportfences) and a watertile is placed as NewObject. So time to launch V1.0!!!!

Suggestions for graphics (and how to get rid of the windflag) are very welcome!

in theory there should be flags you can set so airporttiles don't get flooded. maybe refer to industrytiles, they should be similar. or maybe i dreamt this

Suggestions for graphics (and how to get rid of the windflag) are very welcome!

What about replacing the sprites of this windflag with empty blue (transparent) boxes?

AFAIK their numbers are 2676-2679.
