Add field on vehicle window

[sky81]

I'm trying to add a filed like: "Type: Steam" inside a vehicle window(were are display Cost , weight etc).
I cannot figure out how to do it. Is it possible to add it for only one vehicle, like the name of the bus
Example: 04 01 7F 01 "NAME" 00 ?

[michael blunck]

You would do this by callback 23 (additional text in menu).

[sky81]

Do you have an example how to use callback 23, because it's difficult to understand how to do this in nfo?

Thanks

I saw some grf's that have set this via Action4. Like this one:
3 * 254 04 00 FF 04 00 D0 98 "Manufactuerer: " 8A "Bombardier "
"Transportation " 0D 98 "Model Name: " 8A "Type-S "
"Tram" 00 98 "Manufactuerer: " 8A "Siemens Duewag "
0D 98 "Model Name: " 8A "Type-PT Tram" 00 98 "Manufactuerer: "
8A "Siemens Duewag " 0D 98 "Model Name: " 8A "Type-O "
"Tram" 00 98 "Manufactuerer: " 8A "Siemens Duewag "
0D 98 "Model Name: " 8A "Type-K Tram" 00

But I cannot figure out why is not working in mygrf. I think there is something more that I should write somewhere but I don't know what
For each vehicle I have 3 action2 sprites and one actio3
I'm pretty sure that the last action2 refer to what I want to change
246 * 43 02 01 FB 89 10 00 FF 00 00 00 03 FF 00 09 00 00 00 09 00 00 00 FC 00 0F 00 00 00 0F 00 00 00 00

248 * 43 02 01 FB 89 0C 00 FF FF 00 00 03 FC 00 15 00 00 00 15 00 00 00 FD 00 16 00 00 00 16 00 00 00 FB
00 36 00 00 00 36 00 00 00 FE 00
249 * 53 02 01 FE 89 0C 00 FF FF 00 00 04 FA 00 00 00 00 00 00 00 00 00 FD 00 16 00 00 00 16 00 00 00 03
80 23 00 00 00 23 00 00 00 FF 00 36 00 00 00 36 00 00 00 FE 00
250 * 12 03 01 01 FF 5C 00 01 FF FE 00 FB 00

But when I copy sprites 249 and 250 nothing happens .
P.S. I change the ID in action3 from 5C to my vehicle ID.

I try also deleting last to bytes from Action3 (the FB 00). still nothing

[Eddi]

here's an excerpt from my (NML) code, not a particularly simple example (using the "text stack"):

Code: Select all

switch(FEAT_TRAINS, SELF, text_switch_default,
  [STORE_TEMP(string(STR_AUTO_10) | string(STR_USAGE_CARGO) << 16, 0x100),
   STORE_TEMP(string(STR_TRACK_TYPES_DEFAULT) | string(STR_TRACK_TYPE_N) << 16, 0x101),
   0])
{
 return string(STR_ENG_DESCRIPTION);
}

item(FEAT_TRAINS, [...]) {
 graphics {
  additional_text: text_switch_default;
}

Code: Select all

STR_ENG_DESCRIPTION     :{BLACK}Axle Scheme: {GOLD}{STRING}{BLACK} Use: {GOLD}{STRING}{BLACK}{}Track Class: {GOLD}{STRING}{BLACK}
STR_AUTO_10             :2'2'
STR_USAGE_CARGO         :Freight
STR_TRACK_TYPES_DEFAULT :{STRING}
STR_TRACK_TYPE_N        :{GREEN}unelectrified{ORANGE}

The action 4 above sets the text strings for IDs following ID "D0 00". You have to simply address those IDs in your callback 23. C'est ça.

[Eddi]

Wow!

well, it's not like i did anything there. that's just the output of NMLC...

the "text stack" is awkward anyway, because it's not actually a "stack" (it has no "push" operation. you have to manually store values at the correct locations)

Thank you for your time and support. I try your code, also found some other code but still not appear. After I chaange something in Action3 like added ID of this action2, only then it worked, but not like I was expected. It changed also my picture of the trolley. It is something that I'm missing but I don't know what.
If I use action04 and action2 like you suggested (without action3) should work? As far as I read about action3 is just mapping action0 vehicle id with some cargo define at action2 and also some graphics define at action 2, but I cannot figure out what to do.
Here is a pat of the code:
76 * 1 00
77 * 9 02 01 AA 01 01 00 00 00 00
78 * 9 02 01 DD 01 01 01 00 01 00
79 * 14 02 01 01 81 10 00 FF 01 49 80 01 01 AA 00
80 * 14 02 01 03 81 0C 00 FF 01 01 00 33 33 AA 00
82 * 10 03 01 01 44 01 FF DD 00 03 00
So after Sprite 8 I added somethink like this:
81 * 53 02 01 FC 89 0C 00 FF FF 00 00 04 FA 00 00 00 00 00 00 00 00 00 FD 00 16 00 00 00 16 00 00 00 00
80 23 00 00 00 23 00 00 00 FE 00 36 00 00 00 36 00 00 00 FC 00
When I reffer in action I replace DD with FC (id of the action 2 that I added). then it worked but my trolley changed it's picture

Ah, you didn't mention that you're on cargo culting.

In fact, Eddi and me only showed code snippets illustrating use of callback 23 for extra text in purchase menu.

We didn't provide a complete grf, in no way. I.e., o/c you need proper action 0 and action 3 as well.

regards
Michael

[Eddi]

no, you should not change your action 3. you need to look for the line that checks the "callback" variable, it should be this one in your code snippet:

80 * 14 02 01 03 81 0C 00 FF 01 01 00 33 33 AA 00

there you need to add another case, checking for callback 23.

OK. I'm not very familiar with case. Shold it be something like this:
* 20 02 01 03 81 0C 00 FF 01 01 00 33 33 AA 00 00 80 23 00 02 00 ?
I try also like this with no luck:
* 22 02 01 03 81 0C 00 FF 01 01 00 33 33 AA 00 00 80 23 00 23 00 02 00 ?
I undestant the 00 80 means first item inside action4 block that I define earlier. 02 00 don't know what it means.
Anyway, does not show any additional text with the combination above. Any ideeas?

P/S. I let action3 like it was before:
82 * 10 03 01 01 44 01 FF DD 00 03 00

Thanks for your help

[Eddi]

OK. I'm not very familiar with case.

ok. step backwards for a minute. excercise for you:

take this line

Code: Select all

80 * 14	 02 01 03 81 0C 00 FF 01 01 00 33 33 AA 00

and comment each byte with it's meaning like this:

I looked on the wiki bt I do not understant all the data there. Here is what in uderstood:
80 * 14 // number and length
02 // action 2
01 // feature 1
03 - ID of Action2, to be used in action 03 if neccesarry
81 - I guess it's refering what to access from the callback parameter (example for callback 33 , has a param of 01 00 access 00)
0C - callback
00 FF 01-I'm lost
01 00 - the call back parater or return (I saw that if I set for example 01 80 in callback 23, it will write the 2nd data from action04 string - because of that 01)
33 33 - I guess this is the call back (although I was expected 33 00)
0A 00 - I'm lost

Any help will be appreciated.

I figure out the action2 command but I cannot integrated in Action3.
If I append the command like this:
02 01 03 81 0C 00 FF 01 02 00 33 33 AA 00
00 80 23 23 FE 00
then the text will not appear.
The text appear if I set in Action3 the ID of this text after the action0 ID, like this:
* 10 03 01 01 44 01 FF 03 00 03 00
But I cannot do that because this alterates the graphic picture of the bus.

So the solution is to make another Action2 variaation with same ID like the grapfics: DD
something like this:
188 * 1 00
189 * 9 02 01 AA 01 01 00 00 00 00

But the picture that appear in the buying window is not the one from Sprit 190 or sprit 189.
Like is ignoring Sprit 189,190.
This happens only if I inserted line 193.

Any ideeas?
