NewGRF (Air)ports - general discussion

[LordAzamath]

Nice!
Are you sure I drew those roofs? I'm not sure if I even gave you anything.. (A long time ago it was )..
But just to clear it here.. 8bpp Set doesn't have to do anything with airports concerning infrastructure, once this gets trunkable we will just get these graphics here?

[richk67]

Last time I discussed it with the powers that be, the graphics would be handled this way:

Small, City, Heliport: new airportsbasic.grf uses sprites from main trg1r.grf system file. This allows users of replacement graphics packs to replace the airport tarmac for those airports. This would be a straight TTDP-like replacement, with no advanced features.

Commuter, International, Intercontinental, Metropolitan, Helistation, Helidepot: in airportsextended.grf. Uses sprites embedded in the .grf, not the system sprites. These are skidd13's sprites (mostly). Use of this .grf will allow some advanced features, like multiple airport facings, grass-matching-underlying tile, etc.

Small 2, City 2: in an airport expansion pack of some sort with its own sprites, otherwise identical to airportsbasic.grf. This will be a multi-orientation airport, using the overlays and grass-matching, so that the small airport can have tire tracks over desert, snow, etc. The city airport would be totally grass-matching supporting, using the .grfs sprites.


(NOTE TO SELF: add Misc flag to indicate that the airport supports grass matching, so I can switch it off if necessary. At the moment, it is on by defualt.)

Nice!

I appreciate that.

Very sure... but you seem to cleared up the attachments from your PM's, so I can't tell when you sent it to me.

But just to clear it here.. 8bpp Set doesn't have to do anything with airports concerning infrastruckture, once this gets trunkable we will just get these graphics here?

Well Well... directly there is no connection, but the sprites can be used for the 8bpp set since there is a need for... (And I'd like to see them in full glance in game ).

Here is the new small airport. Ive only done one orientation, so its not as advanced as it could be.

As can be seen, the terrain "reacts" to the terrain underneath.

Minor problems: the railings dont really stand out, except in arctic or desert. Maybe do them in CC instead?
Ive not got the layering right (again), and as the aircraft moves into the next tile, the tailplanes get clipped graphically. Can someone remind me what I need to do to correct this?

They are... well in the darkest ones

"Keep all sprites on their own tile and all bounding boxes correct" is the usual solution.

"Correct" does not necessarily mean "truthful", however.

[richk67]

So, given that for those runway sprites, Ive got no offsets defined at all (ie. first 6 bytes of sprite layout are zero), then is the problem (probably) the aircraft???

[frosch]

If you are not sure whether the bounding boxes are correct:
1. You can enable drawing bounding boxes in game using "Ctrl-B"
2. Grf2Html also creates a preview of bounding boxes in spritelayouts.

If you are sure they are correct, most likely you encountered http://bugs.openttd.org/task/119

[richk67]

Ah yes, it will be that bug. The big difference is that, although the tile is flat (and thus you would not expect it to have the problem), the runway is now part of a sprite layout, where the runway graphic is not the ground tile. The terrain's "standard grass" is the ground tile, and the runway graphic uses transparent areas to show the ground coming through.

Old - Ground tile: Runway; Upper sprites: numbers, etc.
New - Ground tile: terrain standard grass sprite; Upper sprites: runway, numbers, etc.

[mart3p]

I initially had the same problem with the Switchyard (Marshalling yard) in Industrial Stations Renewal. This also uses a grass terrain ground tile, that is overlaid with a sprite with some transparent areas. After trying a number of fixes I found this seems to work:

Code: Select all

		09 08
		// X direction
		8D 0F 00 00 // ground sprite - grass
		00 00 00 10 05 01 2D 04 00 00 // overlay sprite
		80

		// Y direction
		8D 0F 00 00 // ground sprite - grass
		00 00 00 05 10 01 2E 04 00 00 // overlay sprite
		80

		...

This sets the bounding box for the overlay sprite as shown in the screenshot:

bounding boxes.png (7.07 KiB) Viewed 6950 times

In this case, the width (x-extent or y-extent accordingly) of the bounding box (5) is the width of a platform, narrow enough to always be 'behind' the trains. For aircraft you may have to reduce this further. I also found it was necessary to have the height (z-extent) of the bounding box set to at least 1. Even though the overlay sprite has zero height, having the bounding box z-extent set to 0 gave similar problems.

i got a problem with this airport set
it downloads it in a doc format so its like a word pad text,it doesnt work

[Alberth]

Try OpenOffice.

(btw: your message would be much more readable if you exercise your shift and/or punctation keys too, every now and then)

[Momasbrain]

come on,your not blind are you?

It isnt a .grf that loads into normal OpenTTD (trunk). It requires a special build of the NewGRF_ports branch. Then the .grfs for airports are loadable into the compiled version.

1) you need an SVN download to download it
2) you need to compile it yourself
3) it isnt finished
4) the *specification* is in a MSWORD.doc. I will not be changing that. If you want it in a different format, you can convert it.

Hope you like the branch.

Perhaps you could use .odt, but I guess there would also quickly be someone that would find it un-open-able?

Yeah, me. Love it or hate it, MSWORD has been a defacto document standard for over ten years. If your word processor cant load it, then that is, IMO, your problem - not mine.

[Topher]

Uh, not to intrude, but I have OpenOffice.org and it can read .doc files AND edit and save them.

If you want to save a file as .doc, just selct "Save As..." and near the bottom of the window that pops up should be a menu labelled "Save as type:", which has various formats you can select. Three of them are "Microsoft Word 97/2000/XP (.doc)", "Microsoft Word 95 (.doc)" and "Microsoft Word 6.0 (.doc)".

Hope this helps.

Uh, are you aware, that you are reviving two months dead topic with completely useless post?

[jbr]

Not a dead topic, since newgrf_ports has been, and still is, under development for quite some time.

The post was useless, though, I'll give you that.

havnt really read the whole of this topic, but the runway number should be 09 as its facing 090^o
