well here is the tutorial:
1- apply the script to all objects you want to joint
2- the objects have to be close to each other
3- all objects that have the script, will have to have the same tag and you have to assign the tag variable of the script to the tag of your objects
if i didn’t explain well, then ask a question.
You can see how i did my buildings, by seeing and playing my game
So im not sure how this really works, or if im even using it properly… I just have some cubes n stuff here and that and made a tower out of them, put the script on each cube, and gave them all the same tags, added the tag in the script, ran it, it asked for the rigidbody, so i added that, then ran it, and it feels the exact same as adding a rigidbody, i see no difference with this script.
