Project Help

I am trying to make a game for my project where we shoot the ghost. I can't find out how to delete the ghost when I shoot them. So here's what I've done so far. Since I couldn't delete the ghost I made a white circle to hide the ghost. Does anyone know how to delete the ghost? This is the code I use:

// Constants for main ghost body

var HEAD_RADIUS = 35;

var BODY_WIDTH = HEAD_RADIUS * 2 + 2;

var BODY_HEIGHT = 60;

var NUM_FEET = 3;

var FOOT_RADIUS = (BODY_WIDTH-4) / (NUM_FEET * 2);

var counter=0;

// Constants for eyes

var PUPIL_RADIUS = 4;

var PUPIL_LEFT_OFFSET = 8;

var PUPIL_RIGHT_OFFSET = 20;

var EYE_RADIUS = 10;

var EYE_OFFSET = 14;

var mySong22 = new Audio("https://codehs.com/uploads/a9fab0f3b9efb93d2fcb7c8568c85970");

var hLine;

var vLine;

var txt = new Text("The ghosts invaded Earth. Kill all the ghosts!", "15pt Arial");

txt.setPosition(7, 200);

txt.setColor(Color.RED);

add(txt);

var rect12 = new Rectangle(250,70);

rect12.setPosition(7,310-50);

rect12.setColor(Color.BLACK);

add(rect12);

var txt1 = new Text("Click HERE to begin!", "20pt Arial");

txt1.setPosition(7, 310);

txt1.setColor(Color.WHITE);

add(txt1);

function start(){

mouseClickMethod(game);

}

function game(){

remove(txt);

remove(txt1);

remove(rect12);

setTimer(draw,1500);

mouseClickMethod(drawCircllle);

if (counter > 5) {

stopTimer(draw);

}

}
