hit a key to remove picture

[venue92]

Ok so i have objects (circles) falling down the screen, and i need it so that when i hit a specific key referring to a specific one of the circles, the circle disappears. i have no idea how to do this and any help will be greatly appreciated.

Turing:

setscreen ("graphics") var q : int % difficulty variable q:=0 procedure a     %first circle     var c : int     c := Rand.Int (1, 6)     for y : 10 .. 400         drawfilloval (20 + (c * maxx div 7), 400 - y, 20, 20, brightblue)         delay (q)         drawfilloval (20 + (c * maxx div 7), 400 - y, 20, 20, white)     end for end a procedure b     %second circle     var d : int     d := Rand.Int (1, 6)     for y : 10 .. 400         drawfilloval (20 + (d * maxx div 7), 400 - y, 20, 20, black)         delay (q)         drawfilloval (20 + (d * maxx div 7), 400 - y, 20, 20, white)     end for end b %third circle procedure c     var f : int     f := Rand.Int (1, 6)     for y : 10 .. 400         drawfilloval (20 + (f * maxx div 7), 400 - y, 20, 20, purple)         delay (q)         drawfilloval (20 + (f * maxx div 7), 400 - y, 20, 20, white)     end for end c %difficulty selection procedure gui     locatexy (110, 325)     put "Easy"     locatexy (110, 200)     put "Medium"     locatexy (110, 75)     put "Hard"     drawbox (50, 275, 175, 375, red)     drawbox (50, 150, 175, 250, red)     drawbox (50, 25, 175, 125, red) end gui var x, y, button : int gui loop     mousewhere (x, y, button)     if button = 1 and 50 <= x and x <= 175 and 275 <= y and y < 375 then         q := 5         cls         a         b         c     elsif button = 1 and 50 <= x and x <= 175 and 150 <= y and y <= 250 then         q := 3         cls         a         b         c     elsif button = 1 and 50 <= x and x <= 175 and 25 <= y and y <= 125 then         q := 1         cls         a         b         c end if end loop cls

lol I assume this is some form of guitar hero-esque game? Well an easy way to do this is to use Input.KeyDown, then check if a certain key is being pressed.

example

Turing:

var chars : array char of boolean loop Input.KeyDown if chars ("s") then cls end if end loop

should be fairly straightforward

The key is that you're not removing the picture, you're just not drawing it.

Starting from what saltpro15 has, it goes like this:

1. On every iteration through the loop, read all the input from the keyboard and determine which notes are still around and which aren't.
2. cls
3. Draw all of the notes that are still around and everything else for the game.
4. View.Update() to draw everything to the actual screen.

So in step 1, the note becomes inactive. In step 3, we draw without all inactive notes -> your note disappears!
