Overview

Timer tick event.

Generated at regular intervals when the timer is enabled. Provides timing information for animations and game loops.

Example:

termisu.enable_timer(16.milliseconds) # ~60 FPS

loop do
  if event = termisu.poll_event(100)
    case event
    when Termisu::Event::Tick
      # Use delta for frame-rate independent animations
      position += velocity * event.delta.total_seconds
      puts "Frame #{event.frame}, elapsed: #{event.elapsed}"

      # Check for missed frames (SystemTimer only)
      if event.missed_ticks > 0
        puts "Warning: #{event.missed_ticks} frame(s) dropped"
      end
    when Termisu::Event::Key
      break if event.key.escape?
    end
  end
  termisu.render
end
