Major Ver. 2.6 Update Enables More Diverse Battle Experiences
Ver. 2.6 introduces a wide range of new features, including the new Auto Battle feature, enhanced video presentation capabilities and improved movement controls.
In particular, the newly added Auto Battle feature allows multiple battle AIs to be configured and switched according to the situation. This enables a wider range of game design possibilities, including games that make use of automated combat and battle systems where players can switch between different AIs depending on the situation.

RPG Developer Bakin Ver. 2.6 New Features Overview
■ Auto Battle
We have added an Auto Battle feature that allows casts to fight automatically according to preconfigured battle AI settings.
Multiple battle AIs can be created for each cast, allowing users to switch between them as desired or change which battle AI is applied based on specific conditions. Combined with the battle speed adjustment feature, this also makes it possible to create fast-paced Auto Battles
■ Expanded Video Capabilities
Movies can now be treated as image assets, allowing them to be moved, scaled, and rotated.
We have also added support for converting movies into 2D stamps. Once converted, they can be placed on maps or used as event graphics or subgraphics, providing a wide range of possibilities for incorporating video into games.
■ Fixed Movement Direction
We have added a feature that allows cast members to move based on the map’s directional axes, regardless of the camera angle.
This can be useful for creating games with a quarter-view perspective and other similar game designs.
This update also includes numerous feature improvements and bug fixes.
