Earlier & Improved (for DB Set XL) Road Vehicles

Putcha · PostPosted: Wed Aug 29, 2007 12:48 pm

I changed capacity of transported cargo for dbsetxl so the RVs are not useless, mainly goods trucks. For example goods truck can now carry 60 goods, because there is wagon that carry 80 goods. I also changed introduce year and speed (see below).

There are 2 versions:
Earlier Road Vehicles v1.0 - changed only introduce year and speed. Download ERV
Improved Road Vehicles (for DB Set XL) v1.0 - changed introduce year, speed and capacities. Download IRV

List of changes:

Code:

Generation of vehicle:           1st   2nd   3rd   4th    
Introduce year for buses are:   1925, 1955, 1985, 2005
Introduce year for trucks are:  1925, 1965, 2005
Speed of buses [kph]            60,   90,   110,  125
Speed of trucks [kph]           50,   90,   110 

capacities:
Buses                           35,   48,   56,   62
Coal                            20,   26,   30
Mail                            20,   26,   30
Oil                             15,   21,   25
Livestock                       15,   21,   25
Goods                           40,   52,   60
Grain                           20,   26,   30
Wood                            15,   19,   22
Iron ore                        20,   26,   30
Steel                           15,   19,   22
Valuables                       10,   14,   17
Food                            15,   21,   25
Paper                           15,   19,   22
Copper ore                      20,   26,   30
Water                           15,   21,   25
Fruit                           15,   21,   25
Rubber                          15,   21,   25

Any Suggestions?

In which program I can change the speed and and capacity of basic road vehicles? Or there are some other road vehicle set besides Georges longvehicle?

No programs are available which alter vehicle stats in OpenTTD, and other than longvehicles there aren't many truck newgrfs around. You may want to try my one I am currently developing (see "generic road vehicles" in the ttdpatch/graphics forum) *shameless advertising*, but you will need to use a nightly version of openttd.

And its possible to extract that original vehicle set, change stats and export it as standalone grf or edit the game grf (i think its trg1r.grf)?

Unlike downloaded vehicle sets the game graphics are not newgrfs, but just grfs. The original vehicle stastics are hard coded into the game itself and the grf simply contains the graphics; vehicle statistics cannont be modified by modifying the grf. Downloaded newgrfs do, however, also code for the vehicle statistics.

OK. Then I will use the old, but they are in "late game" useless with that low capacities...

You can make a new grf that change stats for default RVs. It will work fine if there are no other RVs sets loaded.

Heh Im not coder

If you can write some tutorial how to change it, I would try it, but i havent any experience.

Thanx anyway.

Hopefully this may be some use for you, otherwise you'll just have to wait for someone else to make a suitable grf I'm afraid

.

Example code for a basic vehicle statistic alteration. Put in a text file, rename to *grfname*.nfo then encode with grfcodec.

Code:

// Automatically generated by GRFCODEC. Do not modify!
// (Info version 7)
// Format: spritenum pcxfile xpos ypos compression ysize xsize xrel yrel

// Number of sprites in the grf
    0 * 4    02 00 00 00

// Action 8: Defines DRF details; GRF ID (AA BB CC DD) and name (Simple Vehicle Demos: Changing Vehicle Properties)
    1 * 56    08 06 AA BB CC DD "Simple Vehicle Demos: Changing Vehicle Properties" 00

//  Action 0: Change vehicle properties; Train 00 speed to 100mph and make double headed
//  Sprite number
//  |   Number of bytes in this sprite
//  |   |        
//  |   |        Action 00: Change vehicle properties
//  |   |        |  Feature 00: Trains
//  |   |        |  |  02 properties: Two properties altered
//  |   |        |  |  |  01 vehicles: On one vehicle
//  |   |        |  |  |  |  Vehicle 00: Trains, so Kirby Paul Tank (Steam)
//  |   |        |  |  |  |  |  Property 09: Maximum speed
//  |   |        |  |  |  |  |  |  Value A0: 100 mph (A0 (Hexadecimal) = 160 (Decimal) = 100 mph * 1.6)
//  |   |        |  |  |  |  |  |  |  Property 13: Double headed?
//  |   |        |  |  |  |  |  |  |  |  Value 01: Double headed (00 = no, 01 = yes)
//  |   |        |  |  |  |  |  |  |  |  |
    2 * 9        00 00 02 01 00 09 A0 13 01

//Thats it!

first attemp - 3 parameters change...

Code:

// Automatically generated by GRFCODEC. Do not modify!
// (Info version 7)
// Format: spritenum pcxfile xpos ypos compression ysize xsize xrel yrel

// Number of sprites in the grf
    0 * 4    02 00 00 00

// Action 8: Defines DRF details; GRF ID (AA BB CC DD) and name (Test - MPS Regal Bus)
//<sprite-number> * <length> 08 <version> <grf-id> <name> <description>    
    1 * 56    08 06 AA BB CC DD "Test - MPS Regal Bus" 00

//  Action 0: Change vehicle properties; RV 00 speed to 60kph and 100 passengers capacity and introduce year is 1925
//  Sprite number
//  |   Number of bytes in this sprite
//  |   |        
//  |   |        Action 00: Change vehicle properties
//  |   |        |  Feature 01: Road vehicle
//  |   |        |  |  03 properties: Two properties altered
//  |   |        |  |  |  01 vehicles: On one vehicle
//  |   |        |  |  |  |  Vehicle 00: MPS Regal Bus
//  |   |        |  |  |  |  |  Property 08: Speed
//  |   |        |  |  |  |  |  |  Value 78: 60kph...   kph*2 -> hex
//  |   |        |  |  |  |  |  |  |  Property 0F: Capacity
//  |   |        |  |  |  |  |  |  |  |  Value 64: 100 people -> hex
//  |   |        |  |  |  |  |  |  |  |  |  Property 00: date of introduction
//  |   |        |  |  |  |  |  |  |  |  |  |  Value 1925: 1925  -> hex
//  |   |        |  |  |  |  |  |  |  |  |  |  |
//  |   |        |  |  |  |  |  |  |  |  |  |  |
    2 * 9        00 01 03 01 00 08 78 0F 64 00 785

//Thats it!

Now Some questions:
I modified only Action0 and name in action8.
How can i know this:
1.

Code:

 // Number of sprites in the grf
    0 * 4    02 00 00 00

2.

Code:

// Action 8: Defines DRF details; GRF ID (AA BB CC DD) and name (Test - MPS Regal Bus)
//<sprite-number> * <length> 08 <version> <grf-id> <name> <description>    
    1 * 56    08 06 AA BB CC DD "Test - MPS Regal Bus" 00

3.

Code:

    //  Sprite number                          ( 2 )
    //  Number of bytes in this sprite         ( 9 )

4. Its in Action0 ... If i want to change 2 properties for all RV it will be:

02 properties: Two properties altered
X vehicles: On X vehicles

or:

02*X properties: Two * X properties altered
X vehicles: On X vehicles
X - all vehicles

or:

again all Action0 section

After last value i can contiune with Vehicle 01: Hereford Leopard Bus ... or i must something add before new vehicle?

1&3: Ignore them. NFORenum will fix them for you automatically.

2. Read the docs. Action8 is among the simplest parts of NFO.

4. If you want to change two properties, then report 02 properties. If you want to change not-two properties then report not-02 properties. The number of vehicles is completely unrelated.

5. No. Go reread the Action0 spec. It's quite clear on the required order when setting a property for multiple vehicles.

If you have read the spec, and don't understand it, specify which sentence(s) (at most two or three per page) you don't understand.

OK, i have code. I have 53 sprites in grf and dont know what should be here:

Code:

// Number of sprites in the grf
    0 * 4    02 00 00 00

Zephyris · **Joined:** Wed May 16, 2007 4:59 pm **Posts:** 2825

53 (Decimal)
--->
35 (Hexadecimal)
--->
00000035 (Add preceding zeros so there are 8 digits; it is a doubleword/dword/D )
--->
35 00 00 00 (Reorder into little endian)

See:
"2) Add the special first pseudosprite" at http://wiki.ttdpatch.net/tiki-index.php ... rstVehicle
"Byte order" at http://wiki.ttdpatch.net/tiki-index.php ... ght=endian

edit:
Alternatively use NfoRenum (viewtopic.php?t=11711), which automatically renumbers all sprites into order, corrects their byte length and changes the number of sprites in the grf to be correct.

edit (again!):
It should look like this once done:

Code:

// Number of sprites in the grf
    0 * 4    35 00 00 00

Lakie · PostPosted: Thu Aug 30, 2007 1:47 pm

Change the number 0x00000002 to 0x00000035 (53 in hex) which should look something like:

Code:

    0 * 4        35 00 00 00

Quite simple when you get used to it, you can use Window's Calculator to convert the decimal to hexadecimal.
Alternately you could be lazy and jut run DaleStan's Renum over it and that would correct it and the length of sprites, and their sprite numbers.

[Edit] Renum would also give you warnings around code which it considers to be wrong, which may help you...

And you've just released your first grf! How does it feel?
