However the part at the top which sets the ID number

What makes you think that? D: The part at the top appears to be a broken fragment of an action 0 (setting 30 properties for one ID, ID 00, and then.. nothing). Doesn't renum complain loudly about that? I'm surprised the grf would compile and run at all with that there.

You need to set the vehicle ID in your action 3, 4 and 0 (sprite 1303 to 1305).

[DJ Nekkid]

the correct code would be: (untested, but cleaned)

Code: Select all

Thanks, for the help again, I've got that sorted, hopefully I shouldn't need help for a while now.

Hi, I'm coding a coal wagon atm, however I'm not shure how to get it to change livery depending on % full, can anyone help?

[DJ Nekkid]

that lies in the action2 itself...


Action1 with 4 sprites:
(-1 * 0 01 00 04 08, action1, for trains, 4 sets, 8 sprites each set)
0: empty
1: a little coal
2: quite a lot of coal
3: full

then you need the action2:

Code: Select all

-1 * 0  02 00 04 04
\w0 \w0 
\w1 \w1
\w2 \w2
\w3 \w3

See?

Hi new problem, I've got a new rail type defined but when trains travel along it they loose all their speed at any corners, I think property 11 controls the speed lost, but by changing it I haven't been able to cause any noticeable effect, can anyone explain this to me?

[planetmaker]

The curve speed for trains depends upon a few things:
- the max speed of the tracks (obviously)
- the the curve length wrt the train.
- the traction type of the track (rail, monorail, maglev give rise to use different formula each).
- the acceleration model being used.
- whether the train is defined as 'tilt' train which would give it 20%(?) advantage over non-tilt trains.

[lawton27]

Hello again, back for some more, help, picked a nice small project for my-self this time, again involving rail types.

When I define a rail type I know it's possible to define brige overlays from what I hear. My question is is it possible to define an overlay for an entire track type, so it goes over all track pieces, much like electric wires do.

If so how?

Thanks, Lawton27

[FooBar]

If you mean an overlay on top of one of the original track sprites: no. Railtype overlays are drawn on top of the terrain tile (so you shouldn't add terrain to your own track sprites).

[lawton27]

Ok thanks for the help, I suppose that makes things simpler, once I've drawn my sprites, I've already defined my rail type but I don't know how to define sprites for it how would I do that?

Thanks for the help.

[FooBar]

Have a look at the Action 3 page, as combined with Action 2 and Action 1 that's what you need.

Here is an example:

Code: Select all

//Track overlays for junctions and PBS
-1 * 0 01 //action 1
	10 //feature: rail types
	01 //num-sets
	\b10 //num-sprites
//flat
-1 sprites/traratrk.pcx 2 10 09 21 40 -19 5
-1 sprites/traratrk.pcx 82 10 09 21 40 -19 5
-1 sprites/traratrk.pcx 162 10 01 7 40 -19 4
-1 sprites/traratrk.pcx 242 10 01 7 40 -19 20
-1 sprites/traratrk.pcx 322 10 01 19 12 11 6
-1 sprites/traratrk.pcx 402 10 01 19 12 -21 6
//slopes
-1 sprites/traratrk.pcx 482 10 09 39 64 -31 -8
-1 sprites/traratrk.pcx 562 10 09 23 64 -31 0
-1 sprites/traratrk.pcx 642 10 09 23 64 -31 0
-1 sprites/traratrk.pcx 722 10 09 39 64 -31 -8

-1 * 0 02 //action 2
	10 //feature: rail types
	A1 //set id
	01 //num-ent1
	00 //num-ent2
	00 00 //entry number
	
-1 * 0 03 //action 3
	10 //feature: rail types
	01 //n-id
	03 //ID
	01 //num-cid
	01 //cargo type: Track overlays for junctions and PBS
	A1 00 //cid
	A1 00 //def-cid

[lawton27]

Thanks for the help, unfortunately, I've got my grf working with no errors and for some reason the sprites don't replace the rails, I'm using exactly the code you have pasted there (and a blank(white) pcx file so I can tell when it works) except I have changed the line '03 //ID' to '00 //ID' so it changes the regular rails but they just appear as normal.

I can't work out what's wrong with the grf.

Thanks,

You need to define a new railtype (via Action0) and preferrably install a railtype translation table. The ID (03 in my case) also references that translation table. So basically you need a lot more than my small example.

Please find attached the complete NFO of (an unreleased version of) my transrapid tracks.

The reason why your graphics don't show up might be because a large number of graphics is mandatory: if you define less, most likely everything is ignored.

[DJ Nekkid]

iirc is overlay and underlay/ballast the req min.

[planetmaker]

You necessarily need to define also the level crossings or you get undefined sprites. And it's better to also define the overlay for bridges or they look out-of-place, too.

[DJ Nekkid]

As I have my own sticky topic i guess this is the appropiate place to post Its been a while since i've had a problem, but parameters and stuff isnt my best field, yet

Im currently working on the NuTracks set, and trying to get it to a 0.9.0 state (1.0 will come when I dont need the track enabler engines, and i can sort the list, see flyspray #4393 and #4394)

But to the problem. The set will featureseveral subsets, selectable by parameter0:

Code: Select all

Value | Meaning
    0 | Autoslect if suitable trainsets is loaded
    1 | Default
    2 | With metrotracks
    3 | With 3rd rails

Anyone have any ideas or solutions?

The auto-thingy is ment to autoselct the metrotracks or the 3rd rails (or even more in the future). I've tried a few approaches, but nothing seems to work yet.

Here is the code i've tried with:

Code: Select all

// Set parameter20 to something if parameter0 is 0 :D (i.e. the autoselect)
-1 * 6  09 PARAM0  01 \7! 00 F0           // Skip to F0 if parameter0 isnt 0. I.e. execute if it is
    // METRO TRACKS
    // Check 2cc trainset
    -1 * 6  07 88 04 0A                   // Jump to, 4 byes range, grfID is not nor will be active - i.e. execute if 2cc set is loaded
            GRFID_2CCSET                  // GRF-ID
            01                            // skip 1 sprite
    -1 * 0  0D PARAM20   80 FF FF \d2     // Sets Parameter 0 to 2 (select metro trackset)
    -1 * 6  09 PARAM20   01 \7= 02 F0     // Skip to F0 if one of the above sets' set parameter0 to 02

    // 3rd RAIL TRACKS
    // Check UKRS2
    -1 * 6  07 88 04 0A                   // Jump to, 4 byes range, grfID is not nor will be active - i.e. execute if UKRS2 set is loaded
            GRFID_UKRS2                   // GRF-ID
            01                            // skip 1 sprite
    -1 * 0  0D PARAM20   80 FF FF \d3     // Sets Parameter 0 to 3 (select 3rd rail trackset)
    // Check BROS
    -1 * 6  07 88 04 0A                   // Jump to, 4 byes range, grfID is not nor will be active - i.e. execute if BROS set is loaded
            GRFID_BROS                    // GRF-ID
            01                            // skip 1 sprite
    -1 * 0  0D PARAM20   80 FF FF \d3     // Sets Parameter 0 to 3 (select 3rd rail trackset)
    -1 * 6  09 PARAM20   01 \7= 03 F0     // Skip to F0 if one of the above sets' sets parameter0 to 03 (might not be neccesary, but in case there is more subsets in the future)    

    -1 * 0  0D PARAM20   80 FF FF \d1     // Sets Parameter 0 to 1 (select default trackset)

-1 * 2	 10 F0                            // Target of skip

What happens is, the metro trackset is loaded no matter what. No trainsets get metro trackset, bros and ukrs2 gets metro tracks.

When PARAM20 is set to this or that it selects different sets of Action0s (and when I get so far, different action1-2-3's)

Code: Select all

-1 * 6  09 PARAM20  01 \7! 01 11
<default trackset Action0s>
-1 * 2  10 11 // Target of skip

-1 * 6  09 PARAM20  01 \7! 02 11
<metro trackset Action0s>
-1 * 2  10 11 // Target of skip

-1 * 6  09 PARAM20  01 \7! 03 11
<3rd rail trackset Action0s>
-1 * 2  10 11 // Target of skip

[frosch]

You are doing weird stuff with PARAM20. No idea what you intend with that, but I think your problem relates from:

If ["variable"] is a GRF parameter that wasn't specified in the newgrf(w).cfg file (...), the action 7 or 9 is ignored and no sprites are skipped (...)

[PikkaBird]

frosch, he's (attempting to) set the value of parameter 20 in the first part of the code.

I believe part of the problem may be your very first line there...

Code: Select all

-1 * 6  09 PARAM0  01 \7! 00 F0           // Skip to F0 if parameter0 isnt 0. I.e. execute if it is

A parameter being undefined is not the same thing as = 0. You might want something like this in there;

Code: Select all

   -1 * 9	 0D 00 80 FF 00 00 00 00 00 // set para 0 to 0 if it is not defined

[DJ Nekkid]

pikka:
that was set by an action14

However, after some chatting on IRC it solved itself
