term.clearLine() EVOLVED

I'm clearly not experimented enough to make a function like this, so if anyone could help me make this I'll be happy.

Here's the idea: a function that clear only a specific part on a line.

I got an idea on how to make it, but not how to script it.

Thanks

Code:

local function clearLine(y)
   local tx,ty = term.getSize()
   local empty = ""
   for i=1,tx do empty = empty.." " end
   term.setCursorPos(1,y)
   term.setBackgroundColor(colors.black)
   term.setTextColor(colors.white)
   term.write(empty)
end

That just does what clearLine already does, except that you have to specify the line instead of it using the line you're currently on. His suggestion was a function that clears only part of a line.

Yeah it would simplify the clearing part of login or even information in a graphic. I've tried to make a function like that myself, but i don't know how to keep whats already written on a line and clear the part i don't want…to resume: i just don't know… :lol:/>

function clearPart(x1, x2, y)
    term.setCursorPos(x1, y)
    local xCur = x1
    repeat
	    write(" ")
	    xCur = xCur + 1
    until xCur == x2
end

Fairly simple. Specify the line ( y ) that you want to start on, the beginning x position ( x1 ), and ending x position ( x2 ).

There's a clearLine() function???
I didn't realize that was your suggestion however…

Thanks Cranium, can I use that function in a program that I'm gonna make public?

Thank you billysback, I appreciate the help you gave me.

Of course you can. Code that gets posted here is usually public anyway…

A slightly shorter version without loops:

local function clearPart(x1, x2, y)
  term.setCursorPos(x1, y)
  term.write(string.rep(" ", (x2 - x1) + 1))
end
