Operations

Operations provides a quick and efficient way to programmatically create animations and complex behavior trees in the Godot game engine. A large collection of built-in operations are provided, with custom operations being very easy to make. It is available in both C# and GDSCript.

For API usage and examples, see either the GDScript README or the C# README. The two APIs are essentially identical - with minor differences due to GDSCript language limitations. The only major difference is that operations are not pooled in GDScript.

Quick Example

Example usage for the death animation of a 2D character may look like this:

C#

using static Operations.Op;

Node character = ...;
Operation op =
    Sequence(
        NodeMove2D(new(0, 32), 2.0f),
        Parallel(
            NodeScale2D(new(2.0f, 2.0f), 1.0f),
            NodeRotate2D(90.0f, 1.0f)),
        NodeModulate(new(1, 0, 0, 0), 1.0f),
        Wait(1.0f),
        Free()
    ).SetTarget(character);

GDScript

var character = ...
var op =
    Op.sequence(
        Op.node_move2D(Vector2(0, 32), 2.0),
        Op.parallel(
            Op.node_scale2D(Vector2(2.0, 2.0), 1.0),
            Op.node_rotate2D(90.0, 1.0)),
        Op.node_modulate(Color(1, 0, 0, 0), 1.0),
        Op.wait(1.0),
        Op.free()
    ).set_target(character)

Installation

Copy either OperationsScript or OperationsSharp from the addons folder into the addons folder of your project. Read more about installing and enabling addons here. The C# version is alternatively available as a Nuget package. Note that to use the demo you will have to git clone the repo, since the artifact is setup for use with the Godot Asset Library.
