2d curved path movement project for Unity

Retroever.Path2d

2d curved path movement project for Unity

This solution will allow you to build a path from bezier curves, then create a client and move it along the path.

⭐ The project has an OOP architecture, which makes it easy to integrate.

How to start

1. Add an empty object to the scene. Add the "CurvedPath" script to it.
2. Create a curve using this component.
3. Create another object with the "ExamplePathClient" script. Specify in it the curve that you created before.
4. ???
5. Press play and have profit 😎

Installation

Make sure you have standalone Git installed first.

And paste this: https://github.com/YooPita/com.retrover.path2d.git

Or just copy the repository to your project files.

Instruction

Path

1. Create a List of Curve Points

var points = new List<CurvePoint>();

2. Fill it with dots

You need to specify only the right handle. The left handle is a reflection of the right handle.

CurvePoint(Vector2 position, Vector2 rightHandle)

3. Create a path

Path(List<CurvePoint> points, int precision, bool isLoop)

• precision - how many points will be set on the curve. The curve consists of segments in order to simplify the search.
• isLoop - is the path closed.

Client

1. Create a client

Create a class and inherit from an interface IPathClient.

In method UpdatePosition(PathPosition position), the client gets its position when it's updated. You need to use this position to transform your client.

PathPosition has get-fields:

• Vector2 Position - position in 2d space
• NormalizedVector2 Normal - forward direction
• float Length - length from the beginning of the path

2. Communication with the path

For convenient interaction with the path, use PathGrip. Create an instance of this object and put it in a variable of type IPathGrip.

PathGrip(IPathClient client, IPath path) - Give him yourself and the path on which you want to move.

• To attach your client to the path, use method Attach(Vector2 position)
• Once a client has been attached to a path, it can be moved. To move the client forward by 1 pixel, pass 1f to the following Move(float movement) method
