Spine safe area

PParimalDubewar · 21 мар 2024

I have been working on project where there are multiple different game objects with different animations.
In game we are triggering those game object animation one after another and disabling spine for game object after a loop is complete and triggering a static png asset of game object on same place. we are doing this approach to save memory and best user experience for all devices.
To be able to switch between static png and spine animation without any displacement. we are exporting static's from spine itself to match it 100%. But we have added a standard safe area in all game object animation, where there is a image 400x600 as a base in spine with 100% alpha so that we don't see safe area in exports. we have made all animation/movements of all game objects with in safe area to maintain placements.
Issue i am facing is most of the spine files are reading safe area in spine but in few of the spine file it is not reading safe are at all. what can be causing issues here. Please let me know.
And if you can suggest better way to approach manage placement in unity for multiple game object. Most welcome.
Thanks.

To address the issue of some Spine files not recognizing the safe area, it's important to ensure that the transparent image used as a safe area is consistently exported and recognized across all Spine files. This could involve several factors:

Export Settings: Ensure that the export settings are consistent across all Spine projects. This includes checking the "Maximal bounds" option during export to ensure that the safe area is considered in the exported files. Refer to the spine-unity Runtime Documentation for detailed export instructions.
Atlas Packing: If you're using texture atlases, make sure that the transparent image is included in the atlas and not discarded during the packing process. This might require adjusting the packing settings to prevent the removal of fully transparent images.
Unity Import Settings: In Unity, verify that the texture import settings for the atlas or individual images preserve the transparency and dimensions correctly. This includes ensuring that the "Alpha Is Transparency" option is enabled for the textures in Unity's Import Settings.

For managing placements in Unity more efficiently, consider the following approaches:

Anchor Points: Use Unity's UI system to anchor game objects at specific points within the canvas. This can help maintain consistent placement across different screen sizes and aspect ratios.
Scripted Placement: Write scripts to dynamically adjust the positions of game objects based on the screen size or other game objects' positions. This allows for more flexible and responsive layouts.
Custom Editor Tools: Create custom editor tools in Unity to automate the placement and alignment of game objects according to your project's specific requirements.

By ensuring consistent export settings and considering Unity's layout tools, you can achieve seamless switching between Spine animations and static PNG assets without displacement issues.

In case Spinebot's answer did not resolve your issue already: Could you please describe what you mean by the above sentence? Please always describe what you expect to see, and what you get instead, if possible with screenshots showing the difference. If the image shows a complete character or scene, please also describe or highlight (with a red rectangle) where we should look to see the difference.
