new TwitchCommands()

@wiiarctus I can confirm this behaviour. As soon as I install BTTV (alongside of FFZ) it stops working. From what I can see, all chat commands offered by FFZ stop working. Seeing as I use the same API as FFZ uses for their commands, there's not much I can do about this. I'd suggest only using FFZ. Is there a specific reason you're using both?

Okay now it is working again, thanks^^ Could you add it so that if I use /rainbow it will use my color that I had before (I had black and after the command a random one^^)?

@wiiarctus It should go back to the color you originally had (if you still have turbo). Twitch can be slow with updating the colors on your own chat (e.g. others will see the changes right away, your rainbow might look like it posts messages in the same color). After the rainbow is done it should show your own color again after a couple of messages (usually 2 or 3). Does it not do this at all? If not then I might have to add some debug code and we can test again.

Hi, I wanted to use multiple emote pyramids so I replaced line 98 of the script with this:

size = params[0]

for (let i = 1; i < params.length; i++) {
    emote += params[i];
    emote += ' ';
}

I don't think this has any adverse effects on regular use except it adds a trailing space which doesn't seem to make it through into the chat, either in between the emotes or after the message. You could get rid of the extra space in line 107 if you want to do this I guess. Thanks for the script!

Hey @BranDougherty , glad you're enjoying the script. I'll see if I might add that into the script, if I don't find any side effects I don't see why not.

Hey, It doesnt work for me i installed all like it stays there and reloadet twitch even restartet my browser

Was working fine, but then it just stopped. FFZ and TamperMonkey are still installed. I've tried reinstalling the script several times but it still doesn't work.

Now with legacy chat gone, any chance on getting an update for the new Twitch chat?

Hey @michaelowens do you have any plans on updating this script? It would be very neat to be able to use it again! :)

Hey @wiiarctus, I was actually thinking about this not too long ago. I might see if I can find some time to make this work for the current FFZ version in the near future.

updated the script here https://gist.github.com/Geczy/acbb9ca28c0d9a1c392474f2e59463b2

Followed the instructions to install, but when I try to type the commands in chat it will just say "unrecognized command".

this tool no longer works with the current version of FFZ.

Is there a tool like this available somewhere? I was looking for something that could do a pyramid primarily.

it doesen't work anymore
