No problem.

I hope some1 can help me soon, i wanna learn to make new grfs!

Lol, too hard for Raichase to do.

Spacy said he was gunna make a tutorial and stuff but he has vanished...

Do you mean the new graphics tutorial from the first post in this thread? That's what you should read to learn how to make new graphics.

If you've read it, it would help if you have specific questions, or tell me what you didn't understand so I can rewrite that section.

- Allright, tell me if i'm wrong: First number before asterisk tells what sprite game uses in it's picture or someway like that.

It's just the number of the entry in the file. Every sprite and pseudo-sprite gets a consecutive number starting from 0.

- Asterisk tells that is a pseudo-sprite (whatever it it ).
- Seventeen tell the number of digits or bytes, how much there are them.
But i don't understand those last byte number, what are they? I tried to read it from readme, but didn't still understand.

The first special byte is "02". That means it's an "action 2" (definition of a cargo ID). So you go to the description of action 2 in newgrf.txt, and it'll explain what all the other bytes mean. Their meaning depends on which action it is.

Thanks Patchman! I'll try that, i'll see if i can do that, and post my problem here. If i have any of them.

Adam and all people who make vehicles, can you post your vehicles online? Then I'll put them in the vehicles section of my graphics site!

Be patient - When i have my exams after me, and I will succesfully set -up my home network then I will attempt to finally release my trucks. For now my comp crashes grfcodec at 42% :/
Oh well - I hope it will work like charm on good ol' Pentium 60 mhz.

Okay, i'll tell now what i know, i'm stuck again...

- 17, number of bytes
- 02, action 2
- second 02, tells that it is a ship, but why there's a zero before a vehicle type number?
- 01, tells that ship carries coal

I don't know anymore... If you could tell about all sprites shortly what they do, i thank you really much.

BTW, what is off-set byte?

What zero? Are you asking why is it 02 and not just 2? That's just how you have to specify the values, as a two-digit hexadecimal number.

- 01, tells that ship carries coal

No, it says that this is the definition of cargo ID number 1. This doesn't have anything to do with what the actual cargo is, that will come later in an action 3 entry.

I don't know anymore... If you could tell about all sprites shortly what they do, i thank you really much.

Well, that's what I did in the instructions. It can't be done "shortly" because there is too much that you need to know.

BTW, what is off-set byte?

Which offset byte? "Offset" just means that something is not at the beginning of something else, but rather offset from the beginning, meaning that it is a number of entries after the beginning.

I've posted an update to the specification in the first post of this thread. This announcement is just so that nobody misses the update accidentally

The goal was to have: new coal truck introduced in 1935, 100 hp, 20mph, 20 tons.
The effect:
No new graphics, overriden hp count, impossibility to set power, weight and speed (for rvpower).

What Am I doing wrong? Looking at Michael's trucks yelded no results...

Your action 1 is wrong. You have 02 sprite blocks, not 22.

thanks - only now i get stragely deformed sprite

But properties 13,14,15 and (i guess) 16 still yield no results...

EDIT:
I think I'm not made of the right clay to do it
Several hours of tweaking and all I got are random crashes, no visible results at all or partial solutions without a clue what might be wrong :/

Hi, I think I have understood the new pseudo sprites

But I can't create the .grf file. Can you tell me how to do it? I have grf codec with the wizard, but it want's a .grf file for encoding. I dont have that. I have olly .NFO and .pcx file.

thanx, Chulio.

EDITED:
I thought

I need more help. I figured out how to generate .grf file (don't use wizzard, use a .bat file with one line: grfcodec -e veh1.grf >t1.txt (you need veh1.nfo in your SPRITES folder, the result will be in veh1.new and t1.txt contains the process (eg what you see on screen while processing)

I have reliazed that I don't understand the 06 action (PLZ HELP)

probably because of the 06 action a have a strange result in my tests look at the picture

what it did ok?
replaced the toyland bus, enabled for temperate climat (and others)
caries 50tons of coal
costs - have no idea
year - 1985
refitable cargo


what it didn't do ok?
graphics - see the picture
speed

look at the picture.

I decoded CARGOSETW.GRF and found here some aditional info that helped me to understand this topic. Speed is not *3.2 mph but /3.2 mph, so max is FF = 79mph

Only thing I can't do better is graphic, if anyone want's to help me and re-draw it, pm me plz. I will send you the .pcx file and after editing I will post it here.

hope it will hel you, I still have to look at the costs and refitable cargo list.
Also I need to draw and define graphics for carriing cargo.

QUESTION:
are properties 13,14,15 usefull, when rvpower is obsolete?

I did encode the file. But i got something like this...
And properties 13,14,15 and 16 do not seem to work at all. Or maybe I screwed something up.

Hi Adam

I think properties 13,14,15 are obsolete, because they require parameter rvpower=1 whitch is obsolete (patch 1.9.1.30)

property 16 is working ok, set it to FF FF 01 00 for all cargo except toyland (including passangers and mail)

my graphics is wrong, i had to convert TrueColor to 256c and I got litle more of green then I wanted

hope tomorow will work everything ok

Chulio

These properties are not obsolete, but rvpower has now become realistic mountain settings, e.g. "mountains=xxx3".

To see weight, power and a speed >127 km/h you need to use realistic mountain acceleration.

Thanx Patchman, it is working now.

for you, who think that these pseudo sprites are hard, I have a litle example: here is my NFO file:

This is all i know so far, you can download my veh2.grf file here, add newgrf/veh2.grf into newgrf.txt and see. Don't forget

it becomes availbale in 1985 +- few random days.

If you think I made here a mistake, please reply, so I can correct myself.

Good luck.
