Vector3 Extensions

Installation

Copy the VectorExtensions directory to your Assets/Plugins folder.
Make the plugins folder if it doesn't exist.

Synopsis

Contains a variety of Vector3 extension methods.

ToGuiCoordinateSystem

var cameraScreenPoint = Camera.main.WorldToScreenPoint(transform.position);
guiPoint = cameraScreenPoint.ToGuiCoordinateSystem();
GUI.Label(new Rect(guiPoint.x, guiPoint.y, width, height), label);

The problem with Camera.WorldToScreenPoint is that the coordinate system returned cannot be used directly in GUI methods because the y-coordinate is flipped. This inverts the Y.

Mask

var a = new Vector3(1, 2, 3)
var mask = new Vector3(1, 0, 1)
a.Mask(mask)
# new Vector3(1, 0, 3)

Use to mask off certain properties in the vector. Useful for working with normals when aligned to a grid.

Abs

var a = new Vector3(-1, -2, 4)
a.Abs()
# new Vector3(1, 2, 4)

Returns the absolute value of the vector.

Inverse

var a = new Vector3(4, 5, 8)
a.Inverse();
# new Vector3(0.25f, 0.2f, 0.125f);

Returns the inverse of the vector.
