I am working on a top down 2D grid based game, where as it is currently, units have a movement and an attack range. An example of this:

enter image description here

The blue squares are tiles the selected unit can move to, the red are tiles they can attack. Defining this is pretty easy, for the weapon/attack I just give it a minimum and a maximum range, and use that to figure out where they can attack. What I would like to do is create attacks that can attack multiple tiles. Something like a straight line would probably be pretty easy, but more complex patterns. Something like the following:

x-x

-x-

x-x

Or

--x--

-xxx-

xxxxx

Where the "x"s are the attackable tiles and the "-"s are not. An example illustration:

enter image description here

enter image description here

I am not sure how I should go about defining this data. I currently save the weapon/attack data in a CSV file, but am open to moving it to JSON as it gets more complicated. But right now I am just drawing a complete blank as to how I should approach this problem. Anyone have any ideas?

Thanks.

    \$\begingroup\$ I would probably give it first an identifier (so your drawing code knows if it expects a single attack or a pattern) and give your drawing an array of places that correspond to the selection. Your first pattern would get something like (-1/+1, +1/+1, 0/0, -1/-1, -1/+1). This will allow you to create any shape you want \$\endgroup\$ Commented Jul 2 at 6:49
