Struggling with function drawing a rectangle in an array for battleships game

in Programming Questions • 1 year ago

Hey,

I am creating a battleships game at the moment and really struggling with one bit...

I need to draw the "ships" (just rect's atm) using an addShipAt function I will include the code I have as that probably makes more sense than my ramblings!

Main Battleships tab

void mousePressed()
{
println((mouseX/50)+0+","+((mouseY/50)+0));
int gridX = mouseX/50;
int gridY = mouseY/50;
myBoard.addShipAt(gridX,gridY,ships[currentShip]);
currentShip++;
}

Board Class

public void addShipAt(int gridX, int gridY, Battleships.ships[currentShip]) {
x = gridX;
x = gridY;
}

I just keep getting errors however I write it atm I am getting this:

TRIPLE_DOT, found '['

Any help would be much appreciated!

Thanks

Will

If your intent is to create a new ship at that position, you should't be passing a ship to the addShip() function, just the coordinates:

public void addShipAt(int gridX, int gridY) {

//etc

As jbum said... You don't use the ship variable, so don't pass it.
If someday you plan to do something with this variable, the correct signature of the function is:
public void addShipAt(int gridX, int gridY, Battleship ship) // You pass only one ship here
If you need to pass an array, the syntax is:
public void addShipAt(int gridX, int gridY, Battleship[] ships)
Note that I use plural in the name to denote an array (or another kind of collection). It is just a convention, but a useful one.
