Can't see the rocket

Question about the task

Resolved

When i try to run my game I don't see rocket. Just see white squares in first row left horizontal and top line. Is this normal or I did something wrong ?

Now we’ll declare several methods that we’ll need in the future.

The check method will check whether the rocket’s coordinates intersect with the landscape.
The win and gameOver methods will be responsible for winning and losing, respectively.
The isStopped method will check the "softness" of the landing. If the rocket hits the platform too hard (speedY is too large), the method returns false.

Requirements:

The MoonLanderGame class must have a private void check() method.
The MoonLanderGame class must have a private void win() method.
The MoonLanderGame class must have a private void gameOver() method.
The onTurn(int) method must call the check() method after the rocket moves and before the call to the drawScene() method.
The Rocket class must have a public boolean isStopped() method.
The isStopped() method must return true if speedY is less than 10*boost.
The isStopped() method must return false if speedY is greater than or equal to 10*boost.

package com.codegym.games.moonlander; public class Rocket extends GameObject { private double speedY = 0; private double boost = 0.05; private double speedX = 0; private double slowdown = boost/10; public Rocket (double x, double y) { super (x, y, ShapeMatrix.ROCKET); } public void move(boolean isUpPressed, boolean isLeftPressed, boolean isRightPressed){ boolean slowdownCondition = true; if (isUpPressed) { speedY -=boost; }else { speedY +=boost; } super.y +=speedY; if (isLeftPressed) { speedX -=boost; super.x += speedX; }else if (isRightPressed) { speedX += boost; super.x += speedX; }else if (!isLeftPressed && !isRightPressed && ((-1*slowdown <= speedX) && (speedX <= slowdown))) { speedX =0; super.x += speedX; }else if (!isLeftPressed && !isRightPressed && (speedX > slowdown)) { speedX -= slowdown; super.x += speedX; }else if (!isLeftPressed && !isRightPressed && (speedX < -1*slowdown)) { speedX += slowdown; super.x += speedX; } checkBorders(); } private void checkBorders() { if(super.x < 0) { super.x = 0; speedX = 0; } else if (x+width > MoonLanderGame.WIDTH) { x = MoonLanderGame.WIDTH - width; speedX = 0; } if (super.y < 0) { super.y = 0; speedY = 0; } } }

solution

ok I have found error. In MoonLanderGame class in line 38 should be like this:

super.setCellColor(x, y, color);
