let see, perhaps we can try getting the input, and instead of putting the variavle, we put "*"...

lets try somthin like:

code:

var input : string (1)      %%gets input
var user_pass : string := ""%%password

loop
    %%this will get your character
    getch (input)

    if input = (KEY_ENTER) then
        exit    %%leaves the loop
    end if

    put "*" ..                      %%So you cant see the pass
   
    %%and actually pass is getting stored here
    user_pass += input
end loop

put user_pass


Ofcoure you can get more specific, like take out backspaces: etc:

Ill let you try to figure it out though, if you need help just ask!

Programming is about thinking... See you have to plan how your programs going to work befor you make it...

So if you want a ball to bound off the wall, which lets say is the left wall, thats at the x chord 0 right?

now, we need the balls chords..

code:

var ballx: int
var bally: int
%x is for sideways, y is upand down


so now we can trace and draw the ball, useing its chords:

We need a speed variable which workds to "ADD" so much pixles to move the ball right / up, or +Minus+ them, to make it go left / down.

code:

%%using negitive 2 because adding a negitive number subtracts the number makeing it move left
var ballxspeed: int := -2
var ballyspeed: int := -2


Lets start that ball 100 frames away from the xwall (0) and move it left to bounce off... we would need to reverse the direction by making the xspeed from neg to positive, we do this my timesing it by -1

code:

View.Set ("offscreenonly") %%to use the update correctly

var ballx : int := 100    %%set it to 100
var ballxspeed : int := -2  %%set to go left

loop
    cls
    ballx += ballxspeed
    %%we wont use y chords
    if ballx <= 0 then  %%when ball hits left wall
        ballxspeed *= -1  %%this just makes the speed reverse, from pos to neg, vise versa
    end if

    %%draw your ball
    drawfilloval (ballx, 100, 10, 10, 7)
    View.Update
    delay (20)
end loop


Try to get it to bounce off the right side, top, and bottom
