I have a function which generates a vector of coordinates in a square board. The result of running this function is something of the form
[{:x 1, :y 0} {:x 0, :y 1} {:x 2, y:3} {:x 3, :y 4}]
After running this function, I need to apply another function to the result above. Since I'd be mapping a function over a collection, I thought using the map function would be appropriate. As such, I wrote the following method:
(defn attack [x y] (map (fn [coord] (println (get coord :x))) [{:x 1, :y 0} {:x 0, :y 1}]))
(I've also tried the example above with get-in instead of get, to no avail)
This is not the final form of the method, and instead is just something I tried to see if I could at least see something printed to the terminal after running
clojure myscript.clj
However, nothing comes out of it and it doesn't seem to matter whether I return a value from the fn function or not. For example, this
(defn attack [x y] (map (fn [coord] coord) [{:x 1, :y 0} {:x 0, :y 1}]))
also returns nothing. Does anyone know how I could at least get access to the values inside the vector in my fn function?
Lastly, does it matter whether my vector is generated by a call to another function?
For example,
(defn attack [x y] (map (fn [coord] coord) (get-attack-coordinates x y)))
would this be a problem? I'm guessing not, but I thought it was a good idea to ask just in case. Thank you all for reading :)
