So recently I was making a model keyboard, and it was going pretty standard, until I decided to label the keys.
Not so bad, but I unfortunately didn’t stop there, and as the first part of my name implies (Disco), I decided it would be a great idea to make it a gaming keyboard, where the text fades into different colors! (It was infact, not a great idea.)
Nonetheless I’m a bit stuck. There are multiple text labels that have to change colors, so I used a loop to specify all of them. I as well used color3 and math.random to generate a random color, of which said text labels will change its color to, which works fine.
Where I hit the roadblock is changing the colors smoothly (with tween service), often getting “Unable to cast to dictionary” errors.
while true do
wait(0.1)
local TweenService = game:GetService("TweenService")
local tweenInfo = TweenInfo.new(5)
local color = Color3.new(math.random(), math.random(), math.random())
for _, v in pairs (script.Parent:GetDescendants())do
if v.Name == 'TextLabel' then
local tween = TweenService:Create(v, tweenInfo, color)
wait()
tween:play()
end
end
end
I’m not exactly the most experienced scripter, so sorry if this is an eyesore to look at.
How would I go about fixing this? Thanks!
The issue occurs because of an incorrect argument type passed through the :Create() method of TweenService. The :Create() method consists of 3 parameters which are (Instance, TweenInfo, Dictionary). Where you went wrong was that you added a Color3 class value into the third argument which only supports a dictionary i.e. the property table.
Dictionaries can be written like this:
{Index = Value}
In this case though, it would be written like this:
{TextColor3 = color}
Now altogether, your code should look like this:
while true do
wait(0.1)
local TweenService = game:GetService("TweenService")
local tweenInfo = TweenInfo.new(5)
local color = Color3.new(math.random(), math.random(), math.random())
for _, v in pairs (script.Parent:GetDescendants())do
if v.Name == 'TextLabel' then
local tween = TweenService:Create(v, tweenInfo, {TextColor3 = color})
wait()
tween:play()
end
end
end
To avoid further issues like this, it would be a good idea to look at the information given through the autocomplete in the Script Editor: As you may see, it is clearly stated that the propertyTable/third parameter is a dictionary, aswell as some other helpful information.
