Bomberman Java Game Download

[Tisha]

Im writing a bomberman game in Java and I have already wrote the code for the map of the game (which contains tiles), the players (and their movement in the map) and now I am stuck in the code for the bomb explosion.

I have a Map class which contains a 2d array of Tiles, which can contain Players, Blocks and Bombs.The Player object have a method dropBomb who calls the method receiveBomb from the Map object (every Player has the reference of the Map object) with the position of the bomb and the bomb. When the Map method receiveBomb is called, the map put the bomb in the correct Tile.My problem is in the explosion of the bomb. Who should care about it? The bomb itself? If it is, should the bomb have the reference for the Tile that contains it? Until now my tile haven't need the Map reference.

One possibility that I thought is to have the Tile reference inside the Bomb object, so, when the bomb explodes (and the bomb knows when it should explode) it calls a method in the tile object for the explosion and the tile calls a method in the map. By the way, I don't know this is a good idea. What should I do?

I have always learned, and live by the rule "the table paints itself". The painter might choose the color and call the method, the floor might decide how the leaks and splatter is shown, but the table paints itself.

Now it's the tile that deals with distributing this force. Lets say you have several kinds of bombs, one power (lets say a number between 1 and 10), and two type (lets say normal, incendiary, freeze).

Now the tile comes in to play. Any tile that gets 'touched' by the force of an explosion needs to call it's "Exploded" function to do stuff. If it is also on fire, there is more to do in the "onFire" function

What tiles are 'exploded' comes from force. Normal tiles with force 4 will give the expotion off to all squares within a range of 4, but if it is a special tile (it knows that from itself), like a mountain tile, it might not be able to advance with that force.

Tile 1 explodes with 4 and gives it to adjacent tiles with force 3. One of those tiles might be a wall, so doens't do anything further. Another is a normal tile, and explodes, and continues giving it forward with force 2, etc. If it is a 'water' tile, the explosion is pushed ofrward, but the fire isn't, etc

In the end it might look like most of the work is done by the tiles, and this is probably even the case. but the first steps: the calculation of the force, type, and the first calls are from the bomb. The bomb explodes. And then the explosion has an effect on the tile. The tile handles that, and if needed propagates it.

Think of your design as a series of events, taken care of one by one in the game loop before eventually being drawn. When your bomb is dropped, it raises an event to the Map in the form of recieveBomb() with the Map being the event controller.

I would suggest having a queue in the Map, that contains all the bombs present. Also, your bombs should have a timer (i.e., CreationTime) so that as bombs get pushed into the queue, you check each bomb in the queue for how long they have been in there and if applicable "explode" them.
