Dual Locomotive trains NML

[temporal8]

I am working on my TGV, in real life consist in two power cars (locomotives) and 8 articulated passenger carriages.

I've seen that adding a second engine to the game and then Ctrl+click to rotate the second one is impossible due to the way each engine is made.

So, I'm wondering what my options are:

- The first would be for the train to have a predefined configuration, that is, the player creates the train and it automatically appears with the 2 locomotives and the 8 cars. (or maybe just 4 so it's not so long)

- That the 2nd locomotive be a simple wagon but with locomotive graphics, in this way the player could customize the length of the train as they want and finally add the "locomotive" wagon.

- Maybe there is a 3rd option that I am not considering?

Thanks in advance.

The third option is "design your graphics to TTD scale, with 8/8 as the maximum length" I suppose...

This is, of course, the correct answer.

What I would suggest is using ID counting to select the front vs rear cars - ie if there are multiple locomotives in the train, the even-numbered ones get the reversed graphics. Should work just fine.

That is very good! hahaha, have a good Sunday.

Thanks a lot, I'm not sure how to do it or I'm not sure I fully understand.

count_veh_id with scope PARENT will get the number of vehicles of a particular ID in the whole train.
count_veh_id with scope SELF will get the number of vehicles of a particular ID in the train from this vehicle on.

By comparing these two values, you can determine whether your vehicle is an even- or odd-numbered locomotive, and select the graphics accordingly.

An even simpler, but less flexible, way of doing it would be to simply use reverse graphics for any locomotive that isn't at the front of the train - but that wouldn't allow you to, for example, connect two train sets together.

I think this would work for me, since I have advanced with my nml knowledge but I am still limited in certain aspects.

What I forgot to say is that I had done tests using dual_headed: 1; I managed to have the second locomotive appear by default, but overlaped with locomotive 1 if there are no cars and overlaped with the last car if there are cars... what can define the position of the second locomotive in order to solve it? or its a dead end?

What's happening there is it's not building the articulated vehicle; vehicles can be dual-headed or articulated, but not both.

I think this would work for me, since I have advanced with my nml knowledge but I am still limited in certain aspects.

I can talk you through it. Do you use the same vehicle ID for all the articulated parts, or are the invisible parts a different ID? Let's see the code.

[temporal8]

You will notice that the ids are not correlative because I only take the parts corresponding to the TGV Sud Est Orange. (actually in the complete code I have all the locomotives first and then the cars)

I am going to post the code in several posts since the forum does not allow me in just one.

Ok, so I can see you're doing a lot more than just invisible spacer parts, and I'm not going to try and unpick it. But since you're using a different ID for every articulated piece, the code to figure out if it's an even- or odd- numbered locomotive would be relatively simple. Just subtract the count of the part from this vehicle on (count_veh_id with scope SELF) from the total count (count_veh_id with scope PARENT), % 2, and bob's your uncle.

The easier alternative, as I said, would be to have reversed graphics for all but the lead locomotive. Just check position_in_consist and if it's not 0 (or 1, 2, etc for the articulated parts), draw graphics that make the vehicle appear reversed.

[michael blunck]

Like pikka said.

And the most easy way would be to restrict such a train to a certain/fixed number of elements and use a modulo function to address them. E.g., this is how I do it for the ICE3 in DBXL:

Code: Select all

...

// ICE3 graphics
   
// number of coaches == 8 (24) or 16 (48)
def(1) veh_posabs(MOD24,
	ref(4) if(0 .. 2)   // 1 - trailer front
	ref(8) if(3 .. 5)   // 2 - panto down reverse
	ref(7) if(6 .. 8)   // 3 - panto down 
	ref(9) if(9 .. 14)  // 4 - middle - no panto
	ref(8) if(15 .. 17) // 5 - panto down reverse 
	ref(6) if(18 .. 20) // 6 - panto up, sparking
	ref(5) else           // 7 - trailer back
)

// depot display
spriteblock(
  set(
   sprite(db#ice3.pcx 10 194 01 16 352 -14 -12)
  )
)

def(0) spriteset(move(0),load(0))

def(2) veh_posabs(MOD24,
	ref(0) if(0)   // visible
	ref(VOID) else // transparent
)

def(3) displaymode(
	ref(1) if(DP_VIEWPORT)
	ref(2) else
)

def(4) art_veh_range(_ICE3, 24)
	               
// make callback for engine attach: only 2 * ICE-3 (=23/46 coaches), not more
def(5) veh_num(
	engine(
		attach(ATT_OK) if(< 23)       // max 7 coaches(3 parts)
		attach(ATT_MOTCARBADNUM) else // "wrong number of railcars" 
	)
)

// attach: only ICE-3
def(6) veh_id(
	ref(5) if(_ICE3)	    // OK
	attach(ATT_CARBADTYPE) else // "wrong type of car"
)

// only coach 6 (15 .. 17) and 13 (36 .. 38) is/are sparking!
def(7) veh_posabs(FRONT,
	effect(electric(4)) if(18, 39) // spark
	effect(NONE) else	        // don't spark
)


// CBs
def(16) callback(
	ref(7) if(CB_POWR)	    // power & ELECTRIC
	ref(4) if(CB_ARTI)	    // articulated
	grftext(TSX_IC) if(CB_TSFX) // "Intercity"
	ref(6) if(CB_ATAC)	    // engine attach
	ref(9) if(CB_RCOL)	    // lights
	ref(3) else		            // graphics
)

...

Thank you very much for your time and all the help pals, I will see what I can do.
