Snakes N Ladders Game Java

The Code Below Shows How To Develop SnakesNLadder Game

Step1 : Create a directory to store your snakesnladder image

Step2 : Create a java file and place a main JPanel. In This JPanel Place SnakenLadder Image.

Step 3 : Now place a new JLayeredPane. JLayeredPane Helps you to place panel above a panel. This panel will be a player that will move when the dice is played.

Step 4 : Take maximum width and maximum height of the main panel. Use maximum width as maximum X valu and maximum height as Maximum Y value.Initially  keep the players  position at maximum height and minimum width. Eg X=450 Y=450 then player.x = 25 and player.y = 425

Step 5 : Make a button that gives the dice value. Use this value to move the player. Eg if dice gives value as 6 then add 25 to player.x value till it reaches maximum X value.

Step 6 : If player.x reaches the Maximum X value, reduce the player.y value(eg if player.x = 425 then player.y = 400) and start reducing the player.x value till reaches to the minimum X value
Step 7 : Repeat this procedure till the player.x and player.y value reaches to the 100 block

Note : Even thought the code has the login snake bite and climbing ladder still you should use some logic for snake bite and ladder climbing to improve your logics
