[Cocos2d-js] Unable to remove attachment

Mr-TWX

Hello,
I'm trying to remove an attachment from a slot by setting it as null :

this.skeleton.setAttachment("SlotName", null);

The code works fine when i run the app with a browser, but when i test it on an emulator (win32 or Android) i get the following error:

ERROR
         JS: C:/DevTools/cocos2d-js-v3.6.1/projects/Kaboodleoo_Mobile/runtime/win32/../../src/Avatar.js:42:Error: js_cocos2dx_spine_SkeletonRenderer_setAttachment : wrong number of arguments

I've already tried to set the attachment to 0 instead of null. That way I don't get the error but the attachment from the slot is not removed.

Does anyone know what am I doing wrong?

BinaryCats

are you setting skins?

Mr-TWX

At the moment my skeleton has no skin apart from the "default" one.
Do i need to have a specific skin set in order to be able to remove an attachment ?

BinaryCats

no, spine can crash sometimes when using a specific combination of skins/slots

Mr-TWX

After some further testing I've found that if try to access a slot by using the method

skeleton.findSlot(slotName)

the whole app crashes when running on an emulator, but it works fine within a browser.

I've found a temporary solution to my issue.
Instead of setting a node's attachment to null I'm setting it to a transparent attachment that I've previously created and added to the skeleton.json and skeleton.atlas files.
Now I can "remove" an attachment by simply setting it to the transparent one :

skeleton.setAttachment("SlotName", "transparentAttachmentName");

The only thing to keep in consideration is that the transparent attachment must be set in the skeleton.json file for every slot that may need it.
