Connections

A connection is a relationship between two or more Control Points. That relationship can be used for a variety of effects: having junctions for your railway game, synchronizing the position and/or rotation of Control Points, defining teleport points between two curves etc…

Select the Control Points you want to connect, and then click on the Connect button in the Toolbar. A Control Point can be part of only one connection, but a connection can have multiple Control Points.

Technically, connections are individual GameObjects with the CurvyConnection component attached. They are stored as children of the Curvy Global Manager GameObject and automatically managed using the Toolbar or corresponding API methods.

You can use a connection in different way: The most common one is to synchronize the position and/or orientation of connected Control Points. To do so, setup the parameters in the connection's inspector accordingly. More about that in the Reference section bellow. You can also make a Controller use connections by defining its Connections Handling. You can use the CurvyConnection class via the API to code your own connections related logic.

Suppose you have two open Catmull-Rom splines, A and B, connected so that A’s last Control Point (CP) is synchronized with B’s first CP. In this case, you have the option to provide data from B’s first CP to A’s last CP, enabling A to shape its final segment in a way that appears seamless, as if B’s control points were actually part of spline A. This option is referred to as Follow-Up. Specifically, B’s first CP is the Follow-Up of A’s last CP.

Follow-Ups are especially useful for spline types that consider the next Control Point when shaping a segment, such as Catmull-Rom or TCB.

Lists all Control Points belonging to a connection

Shows the name of the Control Point. You can select the Control Point or remove it from the connection through the available buttons.

Defines whether the connection's position is applied to this Control Point

Defines whether the connection's rotation is applied to this Control Point

Use the preset buttons to quickly set synchronization options on all the Control Points

List the connection's Control Points that are one of the ends of an open spline

The open spline which Follow-Up is being defining

The end of the spline which is concerned by the Follow-Up

The connected Control Point acting as a Follow-Up

Available only when a Follow-Up is defined

In which direction the Follow-Up should continue on. Available options are:

• To spline's start - The Follow-Up segment continues towards its spline's start
• Nowhere - head to spline's start
• To spline's end - The Follow-Up segment continues towards its spline's end
• Automatic - Automatically selects the best option, based on the position of the Follow-Up within its spline
