Coding pacman in java

Source Code : Pacman Game with Java

pacman is the game to gather all the points in the labyrinth and avoid the spirits. The pacman is cartoon in two ways. His position in the labyrinth and his whole body. We animate his whole body with four pictures, based on the direction. The movement is used to create the impression of pacman buying and selling his mouth. The labyrinth includes 15 x 15 pieces. The framework of the labyrinth is based on a simple array of integers. Pacman has three lives. We also depend the score.

The Commons.java file has some common constants.

These numbers make up the maze. They provide information out of which we create the corners and the points. For example number 19 in the upper left corner means, that the square will have top and left borders and a point. (16 + 2 + 1)

The doAnim() counts the pacmananimpos variable, which determines what pacman image is drawn. There are four pacman images. There is also a pacanimdelay variable, which makes the animation a bit slower. Otherwise the pacman would open his mouth too fast.

boolean finished = true; while (i

This code is part of the checkMaze() method. It checks, if there are any points left for the Pacman to eat. Number 16 stands for a point. If all points are consumed, we move to the next level.

Next we will examine the moveGhosts() method. The ghosts move one square and then decide, if they change the direction.

if (ghostx[i] % blocksize == 0 && ghosty[i] % blocksize == 0) 
Continue only if you have finished moving one square.
pos = ghostx[i] / blocksize + nrofblocks * (int)(ghosty[i] / blocksize);
 
This line determines, where the ghost is situated. In which position/square. There are 225 theoretical positions. (A ghost cannot move over walls. )
 
if ((screendata[pos] & 1) == 0 && ghostdx[i] != 1)
 
If there is no obstacle on the left and the ghost is not already moving to the right, the ghost will move to the left. What does this code really mean? If the ghost enters a tunnel, he will continue in the same direction until he is out of the tunnel. Moving of ghosts is partly random. We do not apply this randomness inside long tunnels. The ghost might get stuck there.
 
if (pacmanx > (ghostx[i] - 12) && pacmanx < (ghostx[i] + 12) && pacmany >(ghosty[i] - 12) && pacmany
 
If there is a collision between ghosts and a pacman, the pacman dies.
 
Next we are going to examine the movePacman() method. The reqdx and reqdy variables are determined in the TAdapter inner class. These variables are controlled with cursor keys.
 
If the pacman moves to a position, where there is a point, we remove it from the maze and increase the score value.
 
if ((pacmandx == -1 && pacmandy == 0 && (ch & 1) != 0) || (pacmandx == 1 && pacmandy == 0 && (ch & 4) != 0) || (pacmandx == 0 && pacmandy == -1 && (ch & 2) != 0) || (pacmandx == 0 && pacmandy == 1 && (ch & 8) != 0))
 
If the pacman cannot move further it his current direction, there is a standstill.
 
public void drawPacMan(Graphics2D g2d)
 
There are four possible recommendations for a pacman. There are four images to all recommendations. The images are used to turn the pacman begin his mouth area shut.
 
The drawMaze () strategy draw a network out of numbers in the wide range screendata. Variety 1 is the staying boundary, 2 is the greater boundary, 4 is the real boundary, 8 and 16 is the decreased limit is the aspect. We just went through all 225 int box network. For example we have 9 in the wide range screendata. We had a bit first (1) and 4th items (8) locations. So we draw down and staying limitations in this particular rectangular shape.
 
if ((screendata[i] & 1) != 0) // draws left
 
Draw a left border if the first bit of a number is set this source code is for the pacman :
