Currently I am all in the spirit of trying out the recently added features on roblox. I want to make a script that attaches a part to a character and rotates with it like a weld. I wanted to try to use attachments because they are used to attach accessories, but I don't know which constraint to use. How would I use constraints? Or, is it better to just use welds?
Use an Accessory. Insert the part you want to attach to the R15 (or R6, this works either way) and name it "Handle". It is especially important that you do this. Then, insert an Attachment into the part with the same name as the Attachment that you want to connect it to; for example, if you wanted to create hair, you would name the Attachment "HairAttachment". Then, the "HairAttachment" inside the Head
of the humanoid will automatically connect with yours and create a weld between them. No scripting required!
