<<-S
* INFO: Framerate Diagnostics
You can display these diagnostics using:
#+begin_src
def tick args
# ....
# IMPORTANT: Put this at the END of the ~tick~ method.
args.outputs.debug << args.gtk.framerate_diagnostics_primitives
end
#+end_src
** Draw Calls: ~<<~ Invocation Perf Counter
Here is how many times ~args.outputs.PRIMITIVE_ARRAY <<~ was called:
#{$perf_counter_outputs_push_count} times invoked.
If the number above is high, consider batching primitives so you can lower the invocation of ~<<~. For example.
Instead of:
#+begin_src
args.state.enemies.map do |e|
e.alpha = 128
args.outputs.sprites << e # <-- ~args.outputs.sprites <<~ is invoked a lot
end
#+end_src
Do this:
#+begin_src
args.outputs.sprites << args.state
.enemies
.map do |e| # <-- ~args.outputs.sprites <<~ is only invoked once.
e.alpha = 128
e
end
#+end_src
** Array Primitives
~Primitives~ represented as an ~Array~ (~Tuple~) are great for prototyping, but are not as performant as using a ~Hash~.
Here is the number of ~Array~ primitives that were encountered:
#{$perf_counter_primitive_is_array} Array Primitives.
If the number above is high, consider converting them to hashes. For example.
Instead of:
#+begin_src
args.outputs.sprites << [0, 0, 100, 100, 'sprites/enemy.png']
#+begin_end
Do this:
#+begin_src
args.outputs.sprites << { x: 0,
y: 0,
w: 100,
h: 100,
path: 'sprites/enemy.png' }
#+begin_end
** Primitive Counts
Here are the draw counts ordered by lowest to highest z order:
PRIMITIVE COUNT, STATIC COUNT
solids: #{@args.outputs.solids.length}, #{@args.outputs.static_solids.length}
sprites: #{@args.outputs.sprites.length}, #{@args.outputs.static_sprites.length}
primitives: #{@args.outputs.primitives.length}, #{@args.outputs.static_primitives.length}
labels: #{@args.outputs.labels.length}, #{@args.outputs.static_labels.length}
lines: #{@args.outputs.lines.length}, #{@args.outputs.static_lines.length}
borders: #{@args.outputs.borders.length}, #{@args.outputs.static_borders.length}
debug: #{@args.outputs.debug.length}, #{@args.outputs.static_debug.length}
reserved: #{@args.outputs.reserved.length}, #{@args.outputs.static_reserved.length}

<<-S
* WARNING:
Your average framerate dropped below 60 fps for two seconds.
The average FPS was #{current_framerate}.
** How To Disable Warning
If this warning is getting annoying put the following in your tick method:
#+begin_src
args.gtk.log_level = :off
#+end_src
#{framerate_get_diagnostics}
