How can I make my tween code more accurate and efficient?

[robeatsdeath (AIRLINE_HOLDER)]

This is my current code and it really looks like a mess and I feel like I’m not scripting this correctly. Is there any way I could redo the code to make it more efficient and accurate?

task.wait(3)
Tween:Play()
task.wait(0.45)
Text.Visible = false
task.wait(0.5)
a = 1
animation.Visible = true
	while true do
	animation.Text = "."
	task.wait(0.3)
	animation.Text = ".."
	task.wait(0.3)
	animation.Text = "..."
	task.wait(0.3)
	a = a + 1
	if a == 4 then
		break
	end
end
Tween2:Play()
task.wait(0.5)
Tween3:Play()

You could reduce this code block:

    animation.Text = "."
	task.wait(0.3)
	animation.Text = ".."
	task.wait(0.3)
	animation.Text = "..."
	task.wait(0.3)

down to a simpler for loop:

animation.Text = ""
for i = 1, 3 do
	animation.Text = animation.Text .. "." -- the '..' concatenates the existing string with another period.
	task.wait(0.3)
end

Furthermore, you could also reduce the while true do loop into another for loop

for i = 1, 3 do
	animation.Text = ""
	for i = 1, 3 do
		animation.Text = animation.Text .. "."
		task.wait(0.3)
	end
end
-- this loops the previous code three times.

if your use of task.wait() waits for the current tween to finish, you could replace it with Tween.Completed:Wait(), this will wait for the current tween to end before continuing the code.

I made it invisible after 0.45 so it doesn’t look funny when scaling down. Overall, I can try to adapt my code to the resources you have shared. I always have problems learning for loops so I’ll have to look into it more, thanks!
