I would like to create a bus station.there are some questions are puzzle me.

First, in .mdl file(large_new), I find these data

{ { 2.0, -15.0, .0 },  { .0, 7.85, .0 },   3.0 },–1

{ { 7.0, -10.0, .0 },  { 7.85, .0, .0 },   3.0 },–2

{ { 7.0, -10.0, .0 },  { 7.85, .0, .0 },   3.0 },–3

{ { 12.0, -5.0, .0 },  { .0, 7.85, .0 },   3.0 },–4

{ { 12.0, -5.0, .0 },  { .0, 12.0, .0 },   3.0 },–5

{ { 12.0, 7.0, .0 },   { .0, 12.0, .0 },   3.0 },–6

{ { 12.0, 7.0, .0 },   { .0, 7.85, .0 },   3.0 },–7

{ { 7.0, 12.0, .0 },   { -7.85, .0, .0 },  3.0 },–8

{ { 7.0, 12.0, .0 },   { -4.0, .0, .0 },   3.0 },–9

{ { 3.0, 12.0, .0 },   { -4.0, .0, .0 },   3.0 },–10

{ { 3.0, 12.0, .0 },   { -7.85, .0, .0 },  3.0 },–11

{ { -2.0, 7.0, .0 },   { .0, -7.85, .0 },  3.0 },–12

{ { -2.0, 7.0, .0 },   { .0, -6.0, .0 },   3.0 },–13

{ { -2.0, 1.0, .0 },   { .0, -6.0, .0 },   3.0 },–14

{ { -2.0, 1.0, .0 },   { .0, -16.0, .0 },  3.0 },–15

{ { -2.0, -15.0, .0 }, { .0, -16.0, .0 },  3.0 },–16

I know they are set path what bus run in the station because i modify some parameters and it work in the game.

the questions

1.I don’t know is that why I delete any group date of that ,the game is crush…

2.if i modify line 2 and line 3 like{ { 7.0, 10.0, .0 },  { 7.85, .0, .0 },   3.0 },–2{ { 7.0, -10.0, .0 },  { 7.85, .0, .0 },   3.0 },–3,(-10 to 10 in line 2) game crush. modification like{ { 7.0, 10.0, .0 },  { 7.85, .0, .0 },   3.0 },–2{ { 7.0, 10.0, .0 },  { 7.85, .0, .0 },   3.0 },–3(-10 to 10 both in line 2 and line 3),it works…what relation they are?

3.– connection

{ { 6.8, -5.0, .2 },  { -13.6, 0.0, .0 },   2.0 },

{ { -6.8, -5.0, .2 },  { -13.6, 0.0, .0 },  2.0 },

how to understand these parameters?? the position of passengers up/down bus?

4.terminals = {{ vehicleNode = 18, personNodes = { 42 }, personEdges = { 21 } },

what is 18,42,21 meaning? i have modified 18 to 1 and found bus is stop at line 2, may be they define which line(node)’s function. am i right? what personEdges meaning?

5.I have development a bus station and copy the path date which in “large_new” to my .mdl file. game crush if i chick my mod icon…I don’t know why…

Second

I have found a script named “laneutil.lua” . I think it is refer to path setting, but I con’t understand algorithms in that…who can explain?;)

thank you
