Hey,
I've been experimenting with newtonian, I love it, but I have a simple
question, because I'm stuck
after adding some emitters
[#newtonian.corporum.ParticleEmitter{:position #newtonian.utils.Vector2D{:x
23.0, :y 280.0}, :velocity #newtonian.utils.Vector2D{:x 0.0, :y 10.0},
:size 8, :life -1, :spread 0.09817477042468103, :emission-rate 4}
#newtonian.corporum.ParticleEmitter{:position #newtonian.utils.Vector2D{:x
200.0, :y 280.0}, :velocity #newtonian.utils.Vector2D{:x 0.0, :y 10.0},
:size 8, :life -1, :spread 0.09817477042468103, :emission-rate 4}]
I want to dynamically change them but this seems to be inaccessible as an
atom?
I can get to individual objects like
(get (nth @newt/emitters 0) :position) ==> #newtonian.utils.Vector2D{:x
23.0, :y 280.0}
but how can I swap the atom at Vector2D?
(swap! (get (nth @newt/emitters 0) :position) :x 200) ==> java.lang.
ClassCastException: newtonian.utils.Vector2D cannot be cast to clojure.lang.
Atom core.clj:2233 clojure.core/swap!
Thank
