Position Pattern

Some of the features work with patterns. This is a set of points placed in space. The points are located relative to the starting point and the direction of the figure.
At the moment, the following features works with figures:

• MultiCast: placing new projectiles at points on the figure.
• Followers: following projectiles to points on the figure.

Following steps are performed.

1. The initial parameters are set.
2. The pattern center is either node position or initial center.
3. The pattern center is shifted by the specified offset.
4. The plane of pattern is determined. This is the plane with the calculated center and the specified normal.
   The normal is relative to the initial direction.
5. Points are placed according to the figure, positioned in the resulting plane.
6. The points are rotated along the normal to the plane at a given angle.

Pattern

This is an object with the following fields.

• origin: Center of the pattern is either a node (set its name in this property) or casting position/projectile position/caster position/etc (set "" for this) (default: ""). See 2.
• posOffset: an offset of the pattern center from the origin (default: [0,0,0]). See 3.
• normal: a normal of plane of pattern, relative to initial direction (default: [0,1,0], i.e. forward). See 4.
• xDepends: determines whether the vertical direction of the pattern affects the resulting plane. See 4.
• Figure: set the initial figure. Then it will be moved/rotated. See 5.
• planeRotate: an angle to rotate a figure along the resulting plane (default: 0). See 6.

Figure

This is an object with the following fields.

• shape: a method of placing points in the figure.
• count: number of points in the figure (default: 1).
• size: some figures have a custom size.

Figure Shape

The points can be located in the following patterns.

• Single (default): all points are in the center of the figure.
• Line: the points are on a straight line.
• Circle: the points are arranged in a ring.
• HalfCircle: the points are arranged in a semiring.
• FillSquare: the points are arranged in a square.
• FillCircle: the points are arranged in a circle.
• FillHalfCircle: the points are arranged in an upper half of a circle.
• Sphere: the points are located on a sphere.
• HalfSphere: the points are located on an upper half of a sphere.
• Cylinder: the points are located on a cylinder.
