help need to disapear the rock from screen

[Anonymous]

Hi guys, this is my first time that I am posting here. I am making the asteroid game and I am almost done. I need help to disappear the rock from screen when I shoot with my gun, and also how can I do this by chance if rock hit my plane, then the plan crash and after2 second, new ship appear. Some one plz help cus this is my first and last assignment in Turing.

here are the codes of my game

View.Set ("graphics:800;600,offscreenonly")

var shipUpper : int := Pic.FileNew ("gun.jpg")
var bulletUpper : int := Pic.FileNew ("bullet.jpg")
var rock : int := Pic.FileNew ("rock.jpg")
Pic.SetTransparentColour (rock, black)
var shipDown : int := Pic.Rotate (shipUpper, 180, -1, -1) % Rotate for down arrow
var shipLeft : int := Pic.Rotate (shipUpper, 90, -1, -1) % Rotate for left arrow
var shipRight : int := Pic.Rotate (shipUpper, 270, -1, -1) % Rotate for right arrow
var bulletDown : int := Pic.Rotate (bulletUpper, 180, -1, -1)
var bulletLeft : int := Pic.Rotate (bulletUpper, 90, -1, -1)
var bulletRight : int := Pic.Rotate (bulletUpper, 270, -1, -1)

var x1, y1, x2, x3, y4, bulletX, bulletY, score, life, rockX, rockY : int := 0
var keys : array char of boolean % they key currently being pressed
var KEY_SPACEBAR : char := chr (32)
var UP_ARROW : char := chr (200)
var LEFT_ARROW : char := chr (203)
var RIGHT_ARROW : char := chr (205)
var DOWN_ARROW : char := chr (208)

life := 20
rockX := 20
rockY := 700
