World Editor: Vector Tool – Arma Reforger
Definitions
- Shape: a Polyline or a Spline, defined by points - the shape can be closed or not
- Polyline: a group of points linked by straight lines
- Spline: a group of points drawing a Bézier curve
Details
Polylines and Splines share the following properties:
Coords: position of the first-placed point
Angle X: rotation of the whole shape on the X-axis from the first-placed point
Angle Y: rotation of the whole shape on the Y-axis from the first-placed point
Angle Z: rotation of the whole shape on the Z-axis from the first-placed point
Scale: shape scale, e.g 0.5 being twice as small, 2 being twice as big
Is Closed: defines if the shape is closed or left open
Line Color: defines the line's colour in World Editor
Creation
New Shape
New Polyline / New Spline is used to create a new shape.
As reminded in the Vector Tool interface,
Ctrl + 
adds a point after the selected one, whereas
Alt + adds a point before the selected one.
Terrain Snapping
Snap to terrain
Checkbox: sets if newly-placed points are to snap to the terrain or to world's zero.
Snap to anchors
Checkbox: sets if dragged points get secured by neighbour points. Anchor snap distance value must be set to a value above zero.
Snap to terrain
Snaps selected points to terrain below them.
Reset elevation
Resets elevation of selected points to world's zero.
Point management
Split
This "cuts" the shape on the selected point and duplicates it: one for the "previous" shape, one for the "next" shape.
Merge
This merges the shapes of selected points that are part of different shapes.
Reverse
Reverses all the points of the selected shape.
Delete
Deletes selected point(s).
Subdivide
Adds an additional point mid-distance between the currently selected point and the next one, or the first one if the last is selected.
Select all
Selects all points of the shape.
Anchor snap distance
This defines the distance from which a dragged point will snap to a neighbouring one. This can be useful for e.g road connections.
Tangent mode
Defines the tangent's behaviour (for a Spline) Possible values:
- Mirror
- Same orientation
- Free
Gizmo mode
Defines if mouse drag and drop can move on all three axis or only flat 2D (X-Z).
Clone point data
Checkbox: when inserting a point with Ctrl + or Alt + , clones the highlighted point's data into the newly created point.
Only active layer
Selects the entities from within the active layer only.
Select entities in shapes
Selects all entities within the shape(s) surface.
Exclude children
When ticked, Select entities... actions will not include children (useful to e.g avoid trees from a Forest Generator)
Select entities near shapes
Expands the search surface - Select near distance must be defined.
Select near distance
Sets the Select entities near shapes additional distance, in meters.
Occlude shapes by geometry
Hides shapes behind terrain/objects.
Show far shapes
Shows distant shapes in the editor, however great their distance is from the camera.
Generators
A right-click on a Polyline's or Spline's ShapeEntity offers options allowing to create and use Arma Reforger/Modding/Official Tools/World Editor Generators.
