Vehicle IDs are the still the 5th byte of an action 0 or 4, and the 4th byte of an action 3, just like Pikka said.
For example
Code: Select all
213 * 7 03 01 01 3E 00 08 00
1st2nd3rd^^
214 * 19 04 01 7F 01 41 "lstom Citadis" 00
1st2nd3rd4th^^
215 * 20 00 01 07 01 3A 0E FF 00 00 00 02 16 03 1E 04 64 06 07 07 14
1st2nd3rd4th^^
If that byte happens to be a quoted character, NFORenum's @@BEAUTIFY command will fix the problem.

are there any way one can make a (passanger) wagon (un)load more then 5 per tick ? i think i did read it somewhere in the documentation, but i cannot find it again...

You can set that with an Action0. In case of road vehicles it's property 07. In case of an other vehicle type it's probably also property 07, but I should check that to be sure.

ahh, i did find it:
Load amount
This is the amount of cargo transferred per unit of time if using gradualloading. The default is 5 for trains and road vehicles, 10 for ships and 20 for aircraft.
would til also apply to the "improved loading algorythm" + "load vehicles gradually" in OTTD?
this is my codeline
00 00 0F 01 58 00 \w2007-01-01 03 \b30 04 \b255 05 00 06
07 17 08 01 09 \w120 0B \w2253 12 FD 13 01 14 \b165 15 00 16 \b31 19 28 27 04

You seem to have lost a byte somewhere there. Doubtless nforenum will pick that up for you.
If you're using a recent version of grfcodec, you can have linebreaks in the action, if that makes it easier to read. You can even put comments in to remind you what each value is.
Code: Select all
00 00 0F 01 58
00 \w2007-01-01 // introduction date
03 \b30 // vehicle life
04 \b255 // etc
05 00
06 // <---- should be another byte here?
07 17
08 01
09 \w120
0B \w2253
12 FD
13 01
14 \b165
15 00
16 \b31
19 28
27 04

will that be dooable with nforenum as well? i use nforenum tho... and the linebreaks would just be kickass
btw: i added 07 behind that 06, and that seemed to fix the problem...

NFORenum will insert linebreaks like that for you, if you ask it and the sprite has no fatal errors. It'll destroy the backslash-formats in the process, though.
GRFCodec will not insert such linebreaks, no matter how much you beg and plead.
Linebreaks in pseudos have been supported since at least GRFCodec 0.9.5. Support for inline-comments was added in 0.9.6 or 0.9.7, I think.

But nforenum will not eat your linebreaks or comments when you run it, which is how I interpreted your question.

The action2 structure appears to be wrong to me.
Code: Select all
7 * 9 02 00 A0 72 01 00 00 00 00
should be more likely, because of the 'loading' sprites
7 * 10 02 00 A0 72 01 01 00 00 00 00
Fixing that should also fix your Action3 renum error message.
The Action0 is incorrect because you've said there will be 15 (0x0F) properties defined and you only defined 112 (0x0C), the following should be more correct.
Code: Select all
10 * 30 00 00 0C 01 72 03 \b30 04 \b255 05 02 06 07 07 08 08 01 0B \w0 12 FD 14 \b80 15 00 16 \b31 17 9f

7 * 10 02 00 A0 72 01 01 00 00 00 00
Fixing that should also fix your Action3 renum error message.
That's not really an improvement. nument1 and nument2 are still 72 and 01, respectively. 7of9, did you really want 72h (114 decimal) different sprite sets to display the quantity of cargo loaded? (But only while moving. While loading, there's only 1 set available.)
When there's an error location given (by "Offset ###:") or implied (in this case, near the bytes "72" and "01") the changes must be made at or before the mentioned bytes; changes after them won't fix anything.
There seems to be a bug there, though; that line should still mark cargo ID A0 as defined. Must investigate.
EDIT: You need to upgrade NFORenum; 3.4.6 accepts the action 3 without comment.

well, thanx there lakie, i thought i had to add the vehicleID to that action 2 thingy, but not it works... atleast code wise, the sprite is butt ugly, but it works
btw dalestan; that 72 is the vehicle ID (normaly cola wagon or something), witch i thought i had to add there, dunno why really

a new quick question;
is it possible to make a livery override with a action A'ed engine?
example;
a new TVG (T.I.M) is drawn, and is action A'ed into the game.
New wagons are drawn as well, but i dont want to use that particular wagon for all engines, so action A is out of the question, action 3 is the normal way to go, but it seems like it need an enitire new engine for that (action 0+1+2+3). Or is there anything i've missed?
Re: trying to obtain coding skills - anyone i can ask?

Just 1/2/3 for the engine, I think. I've never tried, but I think you could leave prop 12 unset for the engine, and attach it to some dummy sprite in the GRF, and follow that 3 with override 3s for its wagons.
Re: trying to obtain coding skills - anyone i can ask?
Posted: 10 Jan 2008 20:34
by DJ Nekkid
not sure if thats what you ment, but i action 0'ed the engine with only prop 12 FD set, followed by full 1 and 2's, and the same for the wagons, and then the action 3 sets, and it worked like a charm
thanx mister

hi all...
i've come a good way if i can say so myself, but i need some slight help sometimes, and i've come across a problem;
I'm makeing a TVG with it's first and last wagon to have different graphics. Both Mail and PAX. Theese are made and declaired. But the problem are, when i have the engines, plus 5 wagons it work as it should, with less then 5 wagons only the first, and middle ones get the proper grapics, but the last one get the middle grapic.
Also, when it's more then 5 wagons, the first, the 3 next, and the 5th wagon get it's proper grapics. See attachment for what i mean.
Code: Select all
eight real sprite Action 1's plus one for the purchase list
nine action 2's;
AA = Engine forward direction
A0 = Purchase list sprite
AB = Engine reverse direction
B0 = Middle PAX wagon
B1 = First PAX Wagon
B2 = Last PAX Wagon
C0 = Middle Mail Wagon
C1 = First Mail Wagon
C2 = Last Mail Wagon
// VarAction2: MAIL
-1 * 0 02 00 C3 81 40 00 BB 01 C2 00 01 01 C0 00
-1 * 0 02 00 C4 81 40 00 FF 01 C1 00 01 01 C3 00
// VarAction2: Pax
-1 * 0 02 00 B3 81 40 00 BB 01 B2 00 01 01 B0 00
-1 * 0 02 00 B4 81 40 00 FF 01 B1 00 01 01 B3 00
// VarAction2: Panto at the Back
-1 * 0 02 00 AC 81 40 00 FF 01 AA 00 00 00 AB 00
// Action 3:
-1 * 0 03 00 01 46 01 FF A0 00 AC 00
-1 * 0 03 00 81 5B 00 B4 00
-1 * 0 03 00 81 5F 00 C4 00
Why is this? I've tried to change the 01's to other numbers, but i cant really get it... Help plx!

BB isn´t a valid AND-mask in your case. Remember, you´re refering to the first vehicle from behind (counting backwards).
In addition,
-1 * 0 03 00 01 46 01 FF A0 00 AC 00
here you seem to always reference your purchase sprite (AC).
