🎮 Addon part modding system ✨
Browse files Browse the repository at this point in the history 
STATUS: ALPHA! Glitchy, only adding a part works, the remove-button is dummy.

This adds a new mod type "addonpart" (file pattern *.addonpart) which works as a partial truck file - when selected, it adds additional elements to it. Currently supported features are: managedmaterials, props, flexbodies. The point is to automate what users had to do manually before: https://docs.rigsofrods.org/tools-tutorials/addons/

The addon parts receive all usual treatment from modcache: they can have preview images, name + description are always displayed, they can be searched for, the MainSelectorUI can be opened in mode 'LT_AddonPart' to show only addon parts. In addition, the search can be filtered by a vehicle GUID, much like with SkinZips. This is an example addonpart (port of https://forum.rigsofrods.org/resources/heavy-bumper-for-the-chevy-k3500.461/):

```
addonpart_name "Heavy Bumper for the Chevy K3500 (Prop, Black)"
addonpart_description "For use with GMT400 88-98 Chevy Truck Pack"

;addonpart_guid <guid>  ~ multiple GUIDs can be specified
addonpart_guid 057b21c8-cb54-496d-88ce-4855a8d6d43d
; * 1990 Chevy 454ss,  * 1990 Chevy k3500    * 1990 Chevy K3500HD
addonpart_guid 6a53ad83-255d-4d5e-bf14-ca0714e5228d
; * 1990 Chevy k2500 Blazer, -SAS, -Suburban

managedmaterials
    CHeavyBumper		mesh_standard		HeavyBumper.dds		HeavyBumper_s.dds

props
    39, 62, 34,    0.50,    0.32,     -0.5,   0,    180,    180, CHeavyBumper.mesh
```

There's a new menu in TopMenubarUI: "Tuning". It lists already installed addonparts and contains [add parts] button which opens MainSelectorUI in 'LT_AddonPart' mode, with GUID filtering for the current vehicle.

To remember what addonparts user selected, an additional mod type was added: "tuneup" (file pattern *.tuneup) - this works like ".skin for addonparts" and has intentionally similar syntax. There are 2 power tools:
* "use_addonpart <filename>" to install an addonpart on the vehicle (multiple can be used!)
* "remove_prop <meshname>" to strip an existing prop from the vehicle.

Note: An option to replace prop was intentionally not implemented because that would be a duplicate feature with addonparts. It's up to user to remove props if and only if they don't want them together with new parts.

When user uses addonpart with a vehicle for the first time, the game creates a .tuneup file for it  in {Documents\My Games\Rigs of Rods\projects\}. When spawning the vehicle next time, the .tuneup is loaded automatically. In the future the menu will be able to save custom tuneups. Here's an example:

```
Tuned 1990 Chevy 454ss
{
      use_addonpart = CHeavyBumperBlackProp.addonpart
	preview =
	description =
	author_name = ohlidalp
	author_id = -1
	category_id = 8100
	guid = 057b21c8-cb54-496d-88ce-4855a8d6d43d
}
```

Under the hood, applying the addonparts to the vehicle works entirely in system memory, no truck files are modified or written.
* "use_addonpart" works by literally introducing a fake 'section/end_section' to the truck file parsed in memory - see `class RigDef::File::Module` and function `ActorSpawner::ConfigureAddonParts()` for details.
* "remove_prop" works as last-minute check in `ActorSpawner::ProcessProp()`, skipping props which are blacklisted.
