Added custom code templatesThe code editor now supports custom template functionality:Click the More (three dots) button in the upper right corner → Script Templates – this opens the code template file. Edit and save it.Newly created code files will then apply this custom template.III. More keyboard shortcuts for card operationsThe following shortcuts have been added for operating card objects on the desktop:Ctrl+A – Select AllCtrl+C – CopyCtrl+V – PasteDelete – DeleteWhen multiple cards are selected via box-selection, the corresponding operations will be performed in batch.IV. Added custom default card back feature You can now add a custom default card back by placing a PNG file named Back.png in the CustomProjectDirectory/CardImages folder.Note: This serves as a fallback. The default card back will only be applied to a card if it does not have a custom back texture set.V. Added two new attributesTwo new attributes have been added to data entity classes, available for use when writing code:The Prefab attribute can be used to mark data entity classes that can be dragged from the Data Panel onto the desktop to generate corresponding game objects. The passed parameter is the storage path of the prefab. The path shown in the figure below is the default storage location for card prefabs. You can add more custom prefabs by importing asset packages.The Image attribute can be used to mark data entities that can display icons or illustrations in both the Data Panel and on the desktop.

I. New Custom Card Shader FeatureUsers can now add dynamic visual effects to cards using the custom card shader feature.How to UseOpen the Data panel (Window → Data), select the Card Table, and drag the desired card to the desktop.Right-click the card and select Edit Card Front.Adjust the dynamic effects in the Shader panel.Save.TexturesMain Texture refers to the card's front artwork. You can import your own custom illustration.Mask is an image used to separate the different layers of the main texture.The mask is painted across four layers, corresponding to the RGBA channels:R – Foreground layerG – Background layerB – Distortion layerA – Midground layerYou can use third-party tools that support per-channel painting (e.g., Photoshop) to process the main texture and create the mask.Workflow in Photoshop (overview):Import the main texture into Photoshop.Select the corresponding channel (e.g., R channel). Paint areas belonging to the foreground layer white, and areas not belonging to it black. (Varying shades of gray can be used for semi-transparent regions.)Paint the RGBA channels one by one, then save when done.Layer GuidelinesForeground layer – Usually has no objects in front, so it can be painted fully white. If there is something in front of it, paint that part black so that effects on the foreground layer are properly occluded.Other layers – Follow the same logic: paint parts that do not belong to the layer black, parts that belong to it white, and use gray tones for semi-transparent areas.Distortion layer – This layer behaves differently. Paint areas that should be distorted white, areas that should not be distorted black, and transitional areas gray to define the distortion intensity clearly.Examples of what can be achieved with the distortion layer: animal fur, clothing, water ripples, fire, flashes, distorted space portals, and more.Per-Layer Effect SettingsEach layer can be customized individually:Texture – Can be set to a single image or tiled.Color – Custom...Read full article on Community Announcements (卡牌游戏研究所)Patch NotesOfficial
