Car chains

[Anonymous]

See this thread on how to add custom cars to the game. Since version 385 you can define a chain of cars that behaves as one vehicle. See here an example:

2017-12-07 02.50.37.png

The garbage trucks were appended to the fire brigade truck to form long, connected vehicles. A better use would be for example a tram or a bending bus. There's basically no limit in the length of the chain.

To append cars to a car just use

Code: Select all

"tail":["anotherCarId",...]  // A list of cars to append

To append the car itself just use null as convenient placeholder. So a chain of a car of length 3 would have a tail of length 2:

Code: Select all

"tail":[null,null]

The car ids used in a tail array have to be already defined. Only the first variant (4 frames make up a variant) will be used for each car in a tail. You may use the empty/invisible car $car_null00 as placeholder between cars in a chain if sufficient.

The code to achieve the fire-garbage-trains as shown above

Code: Select all

[
  {
    "override":true,
    "id":"$carfirebrigade00",
    "type":"car",
    "frames":[{"x":512,"y":657,"w":32,"h":18,"count":4}],
    "tail":["$garbagetruck00","$garbagetruck00","$garbagetruck00","$garbagetruck00"]
  }
]

No extra graphics needed.

What should I do if I want to make a train? The car chain looks like a train, but how to make it run on the rail? Can I add a few lines of code to make it a train?
thanks

[Lobby]

Basically yes, adding

Code: Select all

"flag normal": false,
"flag train": true

to your car chain would allow it to drive on rails. However, you need a building (e.g. a station) that spawns it because it won't be spawned automatically.

I'm very sorry to disturb you again, because I have encountered a terrible plug-in problem. I make a lot of trains, but they always carry a car. Sometimes I make a garbage truck on top of the train, and sometimes the fire engine will be embedded in the locomotive. It's strange. But I firmly believe that this is my programming. There is a problem with the two parameters of X and y. Because when I adjust these two parameters, the situation will change, but it never disappears. There is always this strange problem. What is the problem? How to calculate the four parameters of X, y, W and h when making automobile chain? thank you. I'm very sorry, because my English is not good, this paragraph uses the translation software to translate, if there is something wrong, I'm very sorry.

It isn't your programing, it's your textures.

Hello, How can I stop it from gathering and there is one booth in front and one in the back?

You'd generally add an empty car between them with "$car_null00"

When I put $car_null00 in a side pass this (The cabin of front don't see well) and the other side pass this (The cabin of back don't see well)

Hello, how can you fix this style of bus? There is a $car_null00 between the parts, only the first and second frames have this problem, the third and fourth seem normal

[Jaforzem]

Hello, I was already able to solve the problem and what happened was that the frame size was incorrect, in my case it was too small

[Ostrovsk]

Здравствуйте, я уже смог решить проблему и произошло то, что размер кадра был неправильным, в моем случае он был слишком мал
[/цитировать]
Hello, do you need the first, second and other parts of the transport to be the same size? For example, 15x15?

[Ostrovsk]

You'd generally add an empty car between them with "$car_null00"

Hello, where can I find the Json code for the Vanilla Accordion Bus?

[Ostrovsk]

I don't know what to do and who to contact. I still did not understand how to make an elongated bus normally. I'm not even talking about my bus, I recreated a vanilla model of the bus, exactly like in the game, 3 and 4 frames are absolutely normal, perfect. But the first 2 frames have a hole between the parts. No matter how hard I try, it does not clean. I'll send photos and code
