Issues with TextChatService

[upbeat basin]

--throwing some lines in so this makes sense
events.chatMessage.OnClientEvent:Connect(function(runeName, rune, clampedRarity)
    local color = nil 
    local runeGui = script.Parent.Parent.runeGui[runeName].ScrollingFrame.runeFrame[rune]
    
    if runeGui:GetAttribute("gradient") then
        color = ColorSequence.new(runeGui.UIGradient.Color)
        --How can i apply a gradient?
    else
        color = runeGui.TextButton.TextColor3
        --this sends in an HTML format, how can i make it actually read the data and not just send it
        TextChatService.TextChannels.RBXGeneral:DisplaySystemMessage("`<font color='" .. color:ToHex() .. "'>{" .. rune .. "}</font>`")
    end
end)

you may want to start by using TextChatService.OnChatWindowAdded and TextChatService.OnIncomingMessage

and I don't think you aren't formatting it I don't think, at least not how I normally do it

[upbeat basin]

this is SENDING a message from the server

no chats are added until i add it myself

[frozen shell]

oh

[upbeat basin]

this is just the client side

of actually sending it

[frozen shell]

I found this https://devforum.roblox.com/t/how-do-i-enable-richtext-for-this-textchatservice-chatversion/2817916?utm_source=chatgpt.com

then you could prolly like
local gradient = Instance.new("UIGradient") gradient.Color = ColorSequence.new{ ColorSequenceKeypoint.new(0, Color3.fromRGB(255, 150, 50)), ColorSequenceKeypoint.new(1, Color3.fromRGB(255, 50, 150)), } then set the Parent to where ur text properties

bro 💀

[upbeat basin]

rich text aint the issue it would allow text if i changed how i was puting my hex color, but id like it to be a bit more efficient and not need to MANUALLY TYPE 100 COLORS LOL

oops

accidentally went into caps halfway

also with applying gradients, i already set the color i just need to apply it, i dont know hwo to appy to a text color in the textchat

[frozen shell]

bruh I'm trying, I actually don't know the problem I'm just reading documentation

[upbeat basin]

TextChatService.TextChannels.RBXGeneral:DisplaySystemMessage(`<font color='#00f00'>{" .. rune .. "}</font>`)

this is what it expects

[pale cave]

Color sequences don't have a :ToHex() method, rich text also doesn't have any sort of built in gradient support. My intuition says you should manually interpolate the color gradient and add a font color tag to every character but TextChatService might have support for adding UIGradient (idk)

[upbeat basin]

the gradient will have a different line

thats why i included asking for that

[pale cave]

different line
I don't know what you mean by this, can you explain exactly what you desired result is?

[upbeat basin]

see how its an else?

the first statement doesnt even send a message yet

thats the gradient one

[upbeat basin]

i specifically check if its a gradient so i can handle it differently

[pale cave]

The Color property is already a ColorSequence, you can just do color = runeGui.UIGradient.Color

ty

yk any of the other issues?

[pale cave]

:ToHex() seems to output the hex color without a pound symbol

[upbeat basin]

LOL

TY

I LOVE YOU

TY

TY

I KNEW ITD BE DUMB

i had that issue like 2 days ago

with chat tags

😭

[pale cave]

Also your string interpolation looks kinda wrong, your using both " and `
this is probably what you want

`<font color='#{color:ToHex()}'>{rune}</font>`

[upbeat basin]

youre amazing 🙏

now how do i set a gradient to a chat message?

[pale cave]

My thought is you could loop through every character of the message and give it its own font tag with a color based on the character's position in the string.

works in a text label pretty well
