Action 0B Draft, Eye-Candy addon TTDPatch [Research]

Hi

Because many times people asking the same thing, I think a own topic is necessary now.

Action 0B will be GRF Action code for a new eye candy graphics.
It's the concept to give the ability to show TTD objects with different sprites (sets),
for rail station the sets can be adjusted by the user.

This should make things possible you see here:

This pics were made with a proof of concept hack of 1.9.1 exp-alpha 49a

The current Draft for the new action is this (a copy of the text on my site):

Code: Select all

TTDPatch-RFC Eye-Candy Action B  
Version: 0.2a
Date: 2003/08/07
Author: Oskar Eisemuth

Action B:		Defines new eyecandy set
~~~~~~~~~
May appear anywhere in the .grf file.


Data is <num-version> <set-type> <num-set> <bit-cap> <num-sprites> <pointers> 

	B num-version	versionsnumber
			0 eyecandy alpha

	B set-type	Type of set. 
			(Basenum will be used in the calc later,
			if no basenum, this stuff isn't currently supported)
			0 rail stations	(basenum = 18)
			1 road stations
			2 airports
			3 ship
				
			4 railways
			5 roads
			6 bridges
			7 tunnel

			6 town buildings
			7 industry buildings. 

			8 company headquarters
			9 lighthouses 

			255 rail station placement array (special see annotation)

	B num-set	The set number which can be in the range of 0-7
			following grf can overwrite a set...
	
	B bit-cap	capabilities of this set
			bit 0 	snow sprites 
				all others to zero!

	W num-sprites	How many following sprites this set use
	W pointers	Word pointers to the sprites, the size can be calculated with this:
			basenum (* 2 for snow)

			
set-type = 255: (Station placement array)
Data is <num-version> FF <num-set> <num-bytes> <byte stream of station arrays of 777 Bytes>
	W num-bytes	= 777

These Draft has some problems:
Currently no build year, (when a set becomes available)
How station size could be limited (so it could be work with signal boxes Michael has drawn)
How random sprite selection in a set could work.

Comments, Ideas welcome.

So it's not worth to doing the eye candy patch or how should I interpret it?
Ok, I will close the topic soon

How do you check if a station is used for coals or goods ?
Those waypoints are random ?
Are these dependent on the size of the station, one square long means a waypoint ??

eis_os · Post by **eis_os** » 14 Aug 2003 08:37

The current plan is:

You will get a < and a > control to select the rail station from available sets.
A rail station set can limit it's size to a certain length.

Then there should be some random stuff, so one set will be for the checkpoint stations, which will build random styles ...

Will this mean that a certain station size will have a certain look ?
For instance 4 by 5 stations can have the 'goods' look

Dinges · Post by **Dinges** » 14 Aug 2003 09:18

No, I think he means you can select the type you wan't and that the type you selected is limited to a certain size.

Raichase · Post by **Raichase** » 14 Aug 2003 10:13

Is this part of the enhanced GUI that Michael was talking about?

From what I understand Spiff, (like Dinges said), it will be a case of "Cattle Station/Coal Station/Regular Station etc", and you pick the one you want, then you go to the normal station window and choose the rest of the station normally. Or perhaps the other way around, you choose size, then type of station.

It should then look this:

-------------------------------------------
2 x orientation button/ sprites (will use the current set)

[1] [2] [3] [5] [6] [7]

[1] [2] [3] [5] [6] [7]

Catchmen [ on /off ]

Selection of set [ < ] [ > ]
-----------------------------------------

You will see what set you select in the orientation button.
Otherwise I have to create a new window for selection,
then I need some help from Marcin ...

Raichase · Post by **Raichase** » 14 Aug 2003 10:40

So all in one window? I like that even better

.

Thanks for clearing that up for me

eis_os · Post by **eis_os** » 14 Aug 2003 10:44

The problem will be how the other set will be changed.
Only the station window structure can be expanded like i did,
because I recycled TTO monorail stuff, thanks Marcin...

Is this great eye-candy going to be in Josef's TTDpatch at all?

eis_os · Post by **eis_os** » 14 Aug 2003 13:48

Why not? But only when it's done

SHADOW-XIII · Post by **SHADOW-XIII** » 14 Aug 2003 13:48

like I said every TTDPatch is merging to Josef's TTDPatch

way2good · Post by **way2good** » 14 Aug 2003 13:55

I think that the game is transforming into RT2
-With all those station types
-Electric railways
-Buying other companies

(-And if someone could put that only 21st century Maglev thing into this game)

Dinges · Post by **Dinges** » 14 Aug 2003 15:17

eis_os, will this station selecting be for airports too

I'd like to have passenger and goods airports, hope you can manage this too...

eis_os · Post by **eis_os** » 14 Aug 2003 15:20

This will depent on if can manage to create a completly new window for selection sets (for the stuff you can build and you see in the draft) ...

Dinges · Post by **Dinges** » 14 Aug 2003 15:25

/me hopes it

nilsi · Post by **nilsi** » 14 Aug 2003 15:42

eis_os, do not worry about no answers, we stupid little endusers just use the grf specs as they are written down in sprites.txt How could we help You in defining the structure??? We have just no idea how else it could be done... Thanks for making different graphics possible... i really look forward :-)

I'm not very good at TTD source code, but i'll still ask this:

How can you add (modify?) lines if there is only limited number of them allowed?

I mean, that putting new buttons and windows in takes more lines?

I am not happy with going offtopic, but I will answer it.

Think about it like some big blocks:

# = Something
C = Code
T = TTDPatch
G = GUI Structure
A = Not used stuff, like old TTO GUI Fragments (very rare)
B = TTDPatch New GUI
J = Jump (Reallity: It's a call, maybe you know some basic programming you should know what I mean)
E = End of normal code(not a endmarker, simple something but to show it better)

Code: Select all

TTD before TTDPatch:
#CCCGGGGGAA###GCC###E              |

After TTDPatch work:
#CCJGGGNNGG###GCC###ETTTTTTTT      |
   |.................^

The size relations are total wrong, but now all should get the point.

And thats why you can't make all things true, you can't insert everywhere a call, you can't have more code than | or you need a big rewrite....
You can't simple add GUI Stuff, you need room for it...

Ohh, and some stuff in real world, there isn't simple one call, there are more than 300 calls, other stuff not mentioned...

It's the last time I repeat it, if I simply say doesn't work because of size, it will be enought now...
