GROT module for DragonRuby

A collection of useful things for DragonRuby.

A debbugging helper.

• toggle debug mode
• tick timer: shows the average time used per tick by the developers code
• watch: displays the results of expressions you provide

Put the GROT files in mygame/app. Add this line at the top of main.rb require 'app/grot.rb

To enable the debugger: GROT.debug(true)

To disable the debugger: GROT.debug(false)

To time ticks. Put this at the start of def tick: GROT.tick_start

and at the end: GROT.tick_end

To add an expression to watch: GROT.watch { expression }

require 'app/grot_debug.rb'

def prepare(args)
  args.state.prepared = true
  GROT.debug(true) # must be called ONCE before GROT.tick_start
  GROT.watch { format('Random number: %.3f', rand()) }
  GROT.watch { "It is #{Time.now}" }
end

def tick(args)
  prepare(args) unless args.state.prepared
  GROT.tick_start
  
  # your code
  
  GROT.tick_end
end

This will display the following information at the top of the DragonRuby screen:

• FPS (Default. DragonRuby's framerate calculation)
• DT (Default. The amount of time used by your code per tick)
• DS (Default. The number of seconds taken to perform 60 ticks - try to keep it from going over 1)
