Yes, because the format is not the same, which is why I've told you to recreate the Bb Codes... Here are some float Bb Codes, but I won't help you anymore to create basic Bb Codes if you don't try first by yourself.
Here are the kind of options you had:
- use the "bimg" tag options 'fleft'/'fright' to make an img float [see example in addon presentation]
- use the "encadre" tag options 'flet'/fright' to make some text or any content float [see example in addon presentation]
- recreate some float Bb Codes
- continue to use the XenForo Bb Code Manager and create an "orphan button" (read the manual of the BBM addon to learn what is an "orphan" button - paragraph 10 of the FAQ) in the Bbm Bb Code manager.
Just take a few time to read the manual, to look how is working a Bb Code, then if you have still questions, don't hesitate, but read and try first.
