Helper lines

[Dgzt]

I've created helper line option into editor.

It can be enabled in the Debug render options dialog:

Rectangle helper lines:

Hexagon helper lines:

If the user change the map with a tool it will affect the helper lines also.

I want to migrate my tiled based map into mundus based map and I think it is useful feature.

Renamed HelperLineObject to HelperLineShape. Maybe it is better name.

I've found that the not full hexagons not visible correctly at end of map. I've fixed it.

Before fix:

After fix:

Looks like you put alot into this one, it looks neat in the editor. How do you use this for your game though? Just as a visual aid to help place items on the terrain? Just trying to understand its function.

Side note: I do not see the wireframe shader any more when clicking on the terrain on this branch. Does this replace that?

It is just a visual aid to help in Editor to create hill, mountain, city, river and/or forest in a rectangle/hexagon tile. Like in Panzer Corps game just in 3D.

I'm developing a game what currently uses Tiled based 2D hexagon map and I'm migrating to Mundus based 3D map. While I'm creating mountains, hills, cities, etc on the map I must to know where are "tiles" on the map, where are end of tiles, because a tile contains only mountain or city or hill or something else.

I've already implemented that to show where is the mouse on the map, on which tile. It is visible next to the camera position on status bar:

But this PR is too big and I want to put another PR after this merged.

No, this branch was not up-to-date and didn't contain this fix. I updated with the latest master and now the wireframe shader works.

Sorry for the late input, but would it be a lot of work to draw the NORMAL vector for both rectangle and hex modes?

The normal vector can get retrieved from the existing getNormalAtWordCoordinate() in the Terrain class. It is just a matter of drawing it. If it is too late I can wait till the PR is merged and then add it later.

Sorry, but it is not clear for me how can I use normal vectors in this case when the width can be 2 or more.

[antzGames]

So usually the normal is drawn at the center of the cube/rectangle/triangle of the terrain mesh. Ignore this request as I can try to implement after this PR is merged.

I am not sure how useful this will be for most users but since it's only affecting the editor for debug drawing I approve it.
