lane connector should hide tracks that are not connected

[kianzarrin]

Depends on #782

Setting max turn angle is one way of disconnecting sharp tracks. But it limited to disconnecting by angles. More customizable way of doing this is using lane connector.

To do this we need to patch NetNode.RenderNode() NetNode.PupulateGroupData() and NetNode.CalculateGroupData() . specially around the check flags code.

Use the same version of Harmony as Hide TMPE crosswalks and NS2 to be compatible with those mods. (boformer told me NS2 is buggy and different versions of NS2 don't work with each other :( )

EDIT:

Tasks:

• Create a small test mod for fast testing.
• Write code to check if two tracks should draw connect texture/mesh ShouldDrawConnectTexture().
• import TranspilerUtil code from RM Crosswalks Mod
• Insert ShouldDrawConnectTexture() in every place where there is a check for direct connect inside NetNode.RenderNode() to support close camera.
• Test/Debug
• Optimise: create array/cache to store whether tracks are connected so that it does not have to recalculate every frame.
• harmony: Fix harmony compatibility with NS2. (I think its NS2 that needs to change it harmony)

PLAN: see #734 (comment)

This task needs to be divided into several steps:

1. exclude unconnected direct train connections one a per segment basis
2. exclude unconnected direct train connections one a per direction basis
3. support lod (die hards can use ULOD mod can be used until this is supported). PS: lane connector should post UpdateNode()
4. exclude unconnected direct train connections on a per lane basis for custom assets that have more than one pair of tracks.

The catch is you cannot disconnect all tracks using this mehtod but as long as we are fixing vast majority of problems then i say its an improvement.

This is close to hide TMPE crosswalks mod but much easier since it does not require any image processing.

This approach does not work for multi track

I'll close #647 as this 734 has better detail.

Image from #647:

Would be great if lane connector could toggle the tracks crossing that junction in the image above so that only connected tracks were shown.

Please elaborate.

@aubergine10 Please elaborate.

Now that I see that nice picture of yours I take it back!

I don' think anyone ever wants to do this. but lets say in this picture someone wants all tracks to be disconnected from one another (maybe he wants to paint the connections himself ? maybe he wants to create a funny clip ?) it is not possible to do so using lane connector. if there are no lane connection we fall back to the vanilla connection method.

progress note: my TranspilerUtil has very easy to use code to search for nodeDD, segmentID and instructions. This should be easy.
