how to make a tram set?

[NightFang]

OK basicly what the title says, but a little more to it than that.

I have searched the forum and the wiki, but could not find the information I wanted.

What I want to do is make a tram set as the title suggests, but I want to do that without replacing other units... so a few questions:
1) is it even possible to make new units without replacing old ones (Make a new graphics but not have it replace a graphic already in game, Hope you understand what I mean)
2) how would I go about making articulated trams

Um.... I think that all i wanted to know, So if you could just point me either to where I need to go to find this out, or help me out right here, either way.
So now for what I do know/done:

I have already followed the tutorial in the wiki and replaced a few vehicals in game(even if the train I replaced has flashing yellow lights on it, just wish I knew how i did it so i could reproduce it and add it the the trams I hope to start working on), but have as yet to change thier speed/cargo. So, now you know what I know how to do, just need a bit of help in the other areas.

Also if you think im missing anything here relating to how to make new vehical without replacing the old ones please let me know.

Thanks in advance for any help.

Oh and if you want a copy of the .grf file that has the flashing yellow light on the trains (I personaly think that if I reproduce it onto trams in the right spot it would look really good) , let me know and I'll try and find somewhere to host it (might be easier if you told me somewhere tho)

your in the wrong section ha not really, but the main graphics work for OTTD is based on 32bpp, not the orignal 8bpp.

you'd get more help posting inthe TTDP Graphics section, i do.

to answer you question about not overwritting orignal veches, yes it is possiable for exampile, Gerninc Tram Set dosn'ttake orignal vechiles from the game.

so i'd suggest emailing, PMin the author of that set and asking if you can edit the files for personal us, just to make sure your not braking ny copyright laws.

as far as i know, going about editing the speed and stuff, you need to edit the NFO file, from the GRF.

i'm currently testing my NFO skills also lol not having much luck tho lol, but its a learning process

to your flashing lights, its certain colours fron the TT Pallette, i also have done this, making a bus, with flashing logos lol

here's a link to the Graphics sticky in the TTDP Graphics forum, here but youproberly all ready know about this

everything can be read about on the TTDP Wiki page,

ok, thanks for that tip, and im still learning how to use the .NCO files as well, sort of learning, just a lot of stuff to remeber, and ill try posting where you siad.

Good Afternoon!

2) how would I go about making articulated trams)

In terms of drawing sprites, just draw each carriage individually, like you would a train. As for the coding procedure, the same answer as above. What Tom suggests about asking Zephyris is a good idea as he asked many questions about articulated vehicle coding. He can probably help you a lot.

...the train I replaced has flashing yellow lights on it, just wish I knew how i did it so i could reproduce it...

As Tom said, its due to the colours you used in the palette. if you know which colours do what, you can use them very creatively (I always admire the cinema sign on the TTRS set ). To resolve the current flashing train issue, just replace the problematic yellow with a non-action colour replacement.

your in the wrong section ha not really, but the main graphics work for OTTD is based on 32bpp, not the orignal 8bpp.

Nonsense!! OTTD uses the 8bpp the same as any other. What is correct though...

...you'd get more help posting inthe TTDP Graphics section

...is that you will get a lot more exposure if you post in the TTDP Graphics section as its viewed by more users. Next time, Id use that area for these kinds of questions.

the main graphics work for OTTD is based on 32bpp

Id just like to reiterate that I think this is nonsense. Its just that as only OTTD supports 32bpp, you only see those subjects in this area. Some of us are happy for OTTD to stay with 8bpp graphics

Ok, thanks for all the help so far, I will try asking Zephyris for some help later....

Oh, and I seem to be getting more help here than on the TTDP forum.

That would be because you're expected to have read the documentation before posting there.

[NightFang]

That would be because you're expected to have read the documentation before posting there.

... I guess you did not read the second line of my post.... as I said I had already read that

[Zephyris]

Feel free to deconstruct and play about with the generic tram set - with the .nfo documentation on the patch wiki it should be possible to understand. I would start here: http://wiki.ttdpatch.net/tiki-index.php ... rstVehicle , and once youve mastered the basics the following should help get into my style of coding. If you get stuck please do post code for bugfixing, I'm still quite new to coding but shoud be able to help!

ok, thank you for that, I will try messing around with that a bit later, but not now, to tired now

[NightFang]

Ok, to be more specific I need help finding out what a few of the values are for as they do not seem to be in the wiki.

Here is a line of the code that I am having trouble with: (This is from Zephyris Generic Tram Set that he showd me in another topic)

6 * 41 00 01 10 01 3A 00 F9 13 03 13 04 16 06 07 08 50 09 70 0F 23 10 00 11 6E 0E FF 1C 03 17 00 12 49
16 00 00 00 00 13 05 14 20

Here is what ones I already understand:
6 is the sprite
41 is the length
00 is the action
01 is for road vehicals
10 is the number of props to change
01 is the ammount of vehicles to change
3A is the ID of the one to be change

Now this is where it looses me, I cannot find the value of 00 in the wiki (I do not know what 00 changes), But what I do know with the help of Zephyris is that:
Property 1C (misc flags) is 01 - a so is a tram not a normal road vehicle.
Property 17 (callbacks) is 10, so an articulated vehicle.
Property 0E (graphics) is FF, so uses new graphics

So basicly I just need a bit of help finding what properties there are changing what values. As I as said,I'v looking through the wiki but cant seem to find the answer, mabye I'm just looking right over it, I dont know. Any and all help is appreciated.

Please don't ask the same question more than once.
