Thanks to everyone who tested out the first 4.2.0 beta! We managed to spot and fix a few of the major issues for 4.2.0 beta 2 available today.

You can download the latest beta right now at https://github.com/chrismaltby/gb-studio/releases/tag/v4.2.0-beta2

Wall jumping in Platformer scenes can now be enabled without causing builds to fail, and off-screen actors will no longer randomly appear on screen :-)

There’s also a few new features like keyboard shortcuts for copy pasting scripts and the ability to lock an actor’s direction during "Move To/Relative" events so you can have an actor move right while continuing to face left.

Hoping we’ve found most of the major issues in this version now and this can be officially released soon!

Thanks for your support,

Chris

Application changes since 4.2.0 beta1

• Add ability to lock actor direction when using "Actor Move To/Relative" events so the actor does not change direction during movement
• Add copy (Ctrl/Cmd+C), paste (Ctrl/Cmd+V), paste before (Ctrl/Cmd+Shift+V), comment (Ctrl/Cmd+/) keyboard shortcuts to script event editor can be used when hovering mouse cursor over script event’s title or when hoverring the "Add Event" button
