Second major update

We are excited to announce Quillscript latest update, featuring four major new enhancements designed to improve developers' quality of life. Among other things, we introduce the Variable Modifiers feature, the Checkpoint Directive, and the Sprite and TravelPass built-in commands.

Variable Modifiers let you execute a custom function before a variable value is retrieved, allowing you to modify a variable value or run a required code before the variable is used. Checkpoint offers enhanced flow control to stop the Script until a condition is met in Blueprints/C++ code. Additionally, Sprites is an experimental new feature that brings a dynamic new layer to our interface with customizable, animated icons that enhance user interaction and visual appeal.

Alongside these significant upgrades, this update also includes various minor enhancements, extra helper functions, and bug fixes to improve overall performance and usability.

Release Date: 2024-04-23

Engine Version: 5.4
