Help With Lua

[fsmodding]

Hello

Im a newbie at lua and was looking for some help

i working on a trailer and would like to get the a transform in this trailer to always point in the same direction of the tractor along its x Axis.. if the tractor turns i want the transform to rotate so its always targeting the x axis at it.

How would i go about achieving this. ???

Hi,

when I understand you correctly you want to align a TG in a trailer so that its x axis always points towards the tractor?

Check the script doumentation at GDN:
http://gdn.giants-software.com/document ... ipting.php

There are a lot of commands listed which you can use.

As soon as the trailer is attached you can use the following variable to have "access" to the tractor:
self.attacherVehicle

thanks for the reply Fruktor, but i have no idea where to start with lua. Also Yes you understand properly a transform in my Trailer should have its X axis always point at the tractor.

Could you explain what exactly you want to achieve? Because there's always at least one part pointing towards the tractor (i.e. drawbar to attacher).

yes i know about the drawbar but at slow speeds there can be a offset, so i would like to make a tranforms X Axis is Always pointing at the Tractor.

well ... first of all you should understand how to insert a new script into a vehicle.

As soon as you have a new script you can get started

- get (world) position of (which?) reference node at the tractor
- transform these coordinates into the local space of the part you want to align (actually to the parent of this part )
- align
- done

You might also make use of drawDebugPoint/Line to visualize some of the results.


Still, the question remains what you exactly want to do?
Improving the drawbar? In which situations exactly? Might be a hard job

Hydraulic hoses: There's already a script for that. At least for FS13. I don't know if the original modders already converted the script to FS15, but even if not, you would still have a good base to start with.
That mod is available on FS-UK. Don't know the exact name, but shouldn't be hard to find.
