Hello,

I would like to understand how I can trigger an animation limited in time.

So the below code runs ok and shows a line that is going "down" but I would like to listen to a button press and be able to define  the amount of drop of the line (and actually see the animation).

-- title:  game title
-- author: game developer
-- desc:   short description
-- script: lua
local t=0
local x=96
local y=24
local x1=20
local y1=20
local x2=40 
local y2=40
local color=5
function UpdateLines()
    x1=x1+1
    y1=y1+1
    x2=x2+1 
    y2=y2+1
end
function Drawlines()
    line(x1,y1,x2,y2,color)
end
function TIC()
    cls()
    Drawlines()
    UpdateLines()
end

If I add something like

if btnp(4) then
for i=1,10,1
    UpdateLines()
    end
end

 it will directly go to the dropped stated and not show the animation of the line going down. How can I do this?
Thanks!
