Typewriter effect... but backwards

[RobloxPlayer_9384 (somerandomperson)]

read until end

Hi! So, I made this game and in the main menu there is a section that displays tips. It uses a typewriter effect to type it out, but for some reason I can’t seem to make a typewriter effect that will untype it.

If you want me to clarify on the subject don’t hesitate to ask.

Any help is appreciated, thanks!

May you show your script doing the effects?

Here it is:

For some reason, the UnWrite function just freezes the text.

[bluebxrrybot (blueberry)]

local function typewrite(text)
    textLabel.Text = text
    for i = 1, #text do
        textLabel.MaxVisibleGraphemes = i
        task.wait(0.02)
    end
    textLabel.MaxVisibleGraphemes = -1
end

local function untypewrite()
    for i = #textLabel.Text, 0, -1 do
        textLabel.MaxVisibleGraphemes = i
        task.wait(0.02)
    end
    textLabel.MaxVisibleGraphemes = -1
    textLabel.Text = ""
end

I don’t know why you would need to untypewrite, but here.

Thanks! Btw, what does MaxVisibleGraphemes mean?

[bluebxrrybot (blueberry)]

It will only display x amount of characters from the start of the text. Everything else will pretend the text is still there.

Ok, unfortunately, I ran into an error. It still just disappears instead of typing itself backwards. I’m really sorry but I can’t mark your answer a solution due to that error.

@bluebxrrybot

for i = #textLabel.Text, 0 do

They may have forgotten to specify the step. Try this:
for i = #textLabel.Text, 0, -1 do

The -1 just makes it count backwards.
(Please still give the solution to @bluebxrrybot)

while the length of the text is < 0 ?

also yeah you should use the MaxVisibleGraphenes approach and try get it to work.

UPDATE:

I fixed it!! YAY!

@bluebxrrybot

local function typewrite(text)
    textLabel.Text = text
    for i = 1, #text do
        textLabel.MaxVisibleGraphemes = i
        task.wait(0.02)
    end
    textLabel.MaxVisibleGraphemes = -1
end

This worked perfectly fine.

@bluebxrrybot

local function untypewrite()
    for i = #textLabel.Text, 0 do
        textLabel.MaxVisibleGraphemes = i
        task.wait(0.02)
    end
    textLabel.MaxVisibleGraphemes = -1
    textLabel.Text = ""
end

This, however, must be replaced with:

local function untypewrite()
	for i = string.len(textLabel.Text), 0, -1 do
		textLabel.MaxVisibleGraphemes = i
		task.wait(0.05)
	end
	textLabel.MaxVisibleGraphemes = -1
	textLabel.Text = ""
end

Otherwise, the text just disappears after a few seconds.

@vicy98

while the length of the text is < 0 ?

Yes I admit that was pretty stupid.

[bluebxrrybot (blueberry)]

@RobloxPlayer_9384

string.len(textLabel.Text)

You should use the # operator. It returns the length of tables and strings. string.len is most likely deprecated, or at least not used anymore. Sorry for forgetting to set the for loop increment to -1, I almost never use for loops that go backwards.

[RobloxPlayer_9384 (somerandomperson)]

No probs. Thanks for letting me know about the deprication.

[Quwanterz]

Please don’t avoid it. It’s not a deprecated function. Hashtag before a string and string.len do the same thing. It’s just preference.

Could somebody please help me with this
