This problem is based on a 2D platform game called Mario, where Mario has to move from left to right, climbing up structures and jumping over gaps as needed.
In this problem we need to complete the createPyramid() method such that the method can draw a Pyramid composed of blocks, each block is exactly the same size as a single tile. The method should be able to draw pyramids of different sizes between one block high and 8 blocks high.
The example pyramid below is of size = 3, so has three blocks at the base, and is 3 blocks at its highest point. The two halves of the pyramid are separated by 2 tiles, so that Mario has to jump over the gap in the final game.
The screen is composed of 24 tiles across and 20 tiles down. Each tile can be positioned by how far across it is, and how far down it is. Thus the tile (0, 0) is in the top left hand corner, and the tile (23,19) is in the bottom right hand corner of the screen.
Each tile is 30 pixels across and 30 pixels down. The tiles that are used to create the pyramid are called Block. To add a new block to the screen uses code as shown below:-
Block Block = new Block();
addObject(Block, x, y);Where x is how many tiles across, and y is how many tiles down is wanted.
- The program should ask the user for the size of the pyramid as a number between 1 and 8.
- The program should ask again if a number less than 1 or more than 8 is entered
- The program should then draw a pyramid of the right size, and with a 2 block gap in the middle
You can use the Greenfoot ask() method to aks for a string whcih can then be converted to an integer.
String reply = Greenfoot.ask("Enter the pyramid height (1-8) > ");
int height = Integer.parseInt(reply);
