GDScript Tween - Python Introduction

In game development, animations and transitions play an important role in enhancing the gaming experience. Tearing down the complexity of transition animations, Godot game engine provides a useful module called Tween. Using Tween, developers can perform various animations and transitions such as fading, scaling, rotating and more.

This module is available in GDScript and Python for Godot game engine. In this article, we will explore GDScript Tween in Python and learn how to use it to create transition animations.

Installation

To use Tween in Python, you must have Godot game engine already installed. You can download it from the official website. Once you have installed the engine, you can create a new project and start coding.

Usage

To use Tween in your Python code, you must first import it by including the following line at the top of your code:

from godot import *

This will import all the necessary modules required to use Tween and other functions in your code.

Creating a Tween Instance

To create an instance of a Tween in Python, you can use the following code:

tween = Tween.new()

This code will create a new Tween instance that can be used to perform various transition animations.

Adding a Target to Tween

To make any transition animation, you must specify a target node. A target node is the node that you want to apply the animation on. To add a target node to your Tween, use the following code:

tween.interpolate_property(node, "property_name", from_val, to_val, duration, easing_type)

Here, node is the target node, property_name is the name of the property that you want to animate, from_val is the initial value of the property, to_val is the final value of the property, duration is the duration of the animation in seconds, and easing_type is the type of easing function to use.

Starting Tween

After adding targets to your Tween, you need to start it to perform the animation. To start Tween, use the following code:

tween.start()

This code will start animation on your target nodes.

Using Calls

Calls are used to chain different Tween animations and perform them one after the other. To use calls in your Tween, use the following code:

tween.interpolate_property(node1, "property_name", from_val1, to_val1, duration1, easing_type1)
tween.interpolate_property(node2, "property_name", from_val2, to_val2, duration2, easing_type2)

tween.interpolate_callback(node1, duration1, "method_name")
tween.start()

Here, node1 and node2 are two target nodes, property_name is the name of the property you want to animate, from_val and to_val are initial and final values of the property, duration is the duration of the animation in seconds, easing_type is the type of easing function to use, and method_name is the name of the method that will be called after the animation is complete.

Conclusion

Tween in Godot game engine is an essential module for creating transition animations. If you want to make your game more interactive with animations, Tween is your best option. If you are using Python in Godot, you can use the above-mentioned code snippets to create captivating transition animations.
