Hi,

I have posted a few times regarding usage of Bounding Boxes for frame by frame animation and already requested a few enhancements like having the runtime load the theirs colors.

I noticed now that while duplicating a skin, the duplicated bounding boxes use the default color and I need to manually set them again. This is small but I think this can be considered a bug as it's losing information any user would rather keep.

To reproduce, attach a bounding box to a skin, set a custom color to the bounding box. Duplicate the skin, notice the bounding box for the new skin has the default color.

I'm on version 3.8.99.

Thanks!

Ah makes sense, I was using the API wrong then,

computeWorldVertices

works fine. Thanks!

Hi,

Following my attempts at using Bounding Boxes for fighting game like boxes: More precise Bounding Box?

I'm setting colors for bounding boxes in Spine. Keeping attacks in red and defense in blue for example makes sense for me. The C++ runtime (if not all of them) doesn't read the color value for bounding boxes. I easily added the code myself to my local copy but would be nice to have for everyone.

Thanks!

Hi,

I'm extending a Godot's unofficial C++ runtime, following work on: More precise Bounding Box?

I managed to get a chosen Spine bounding box used the the physics shape and get all bounding boxes rendered for debugging purposes, being keyed and all. As one would for a fighting game.

The one thing missing is the 'deform' entries for bounding boxes. How should I interpret those? Is there any docs I can refer to?

"deform": {
   "default": {
      "defense": {
         "defense": [
            {},
            {
               "time": 0.1667,
               "offset": 4,
               "vertices": [ 25, 0, 25 ]
            },
            { "time": 0.4167 }
         ]
      }
   }
}

Then from C++ for slot->getDeform() I'm getting an array of [-25, 0, -25], not sure what to do with that info to modify the rectangle.

Thanks!

Sounds great, good to know about the libgdx runtime.

I got Spine Essential, re created what I had and tried export, manual fix, re-import, it works!

Re-importing into the same skeleton gets messed up, but re-importing as a new project worked perfect. Just saved over previous project after verifying everything is in place. Re-exported and verified nothing changed but the hash at the top so it seems perfectly stable.

Now to try getting this into Godot and making sense into a game!

Thank you very much!

I tried https://github.com/rayxuln/spine-runtime-for-godot and works fine but doesn't integrate Spine's Bounding boxes to Godot.

So with a bit of work I made the SpineSprite behave like a CollisionShape2D or CollisionPolygon2D

Here the PlayerAnimation being a KinematicBody2D needs a direct child to provide a shape:

With my small addition I can set a bounding box from Spine's skeleton to be set as collision shape so the warning is gone:

I made these two Spine icons btw:

For now the shape doesn't render but works fine when moving and colliding. Still need to update it on every frame too. Also need to make the bounding boxes easily accessible for attack collision checks but this proves that it mostly works.

Hi, thanks for the very quick and thorough reply. I can try that approach.

Leaving performance aside, for the platformer part, when doing collision against floor and ceiling it's easier with a rectangle, that's the main motivation to have AABB hitbox. For attack/damage purposes there is no way the user could tell so it's fine.

I'm on the trial version so I can't test it. Could I export, edit a text file manually and re-import without loss? That might be the simplest.

[EDIT] I mean drawing mostly rectangular shapes on the editor, and manually fix them in a text file.

Hi,

I'm trying to get started making a game with Godot, grabbed some graphics from Dustforce to try mocking up an action platformer game. Tried the animation in there and it is very awkward for layered frame by frame animation with keyframed collision boxes, as one would like for fighting game or an action platformer. I'm thinking I could try writing a plugin or improving the editor but feels like too much work...

I decided to give Spine a try! Take a look at the attached screenshot, I basically managed to do exactly what I needed to make the attack animation look right, have 2 animated layers and attack and defense bounding boxes.

The only problem is that the bounding boxes are free-form polygons. I couldn't find a way to edit the vertices of the polygon based on numbers. I would rather making the boxes as AABB rectangles for easier collision checks. Circles would also be nice.

Is there any way to achieve precise control of the Bounding Boxes as regular polygons?
