Overview

High-performance 60Hz fixed-timestep game loop implementing Glenn Fiedler's "Fix Your Timestep" architecture. Decouples physics/simulation updates from variable-rate terminal frame rendering with interpolation.

Defined in:

opal/game/loop.cr

Constructors

• .new(target_fps : Int32 = 60, tick_rate : Int32 = 60)

Instance Method Summary

• #fps : Float64
• #frame_time_ms : Float64
• #on_render(&block : UI::Buffer, Float64 -> Nil) : self
• #on_update(&block : Float64 -> Nil) : self
• #pause : Nil
• #paused=(paused : Bool)
• #paused? : Bool
• #resume : Nil
• #run(buffer : UI::Buffer, max_frames : Int32 | Nil = nil) : Nil

  Runs the main loop synchronously until stop is invoked or max_frames is reached

• #running=(running : Bool)
• #running? : Bool
• #stop : Nil
• #target_fps : Int32
• #target_fps=(target_fps : Int32)
• #tick_once(dt : Float64 | Nil = nil) : Nil

  Performs a single fixed-timestep update tick (useful for headless testing and step debugging)

• #tick_rate : Int32
• #tick_rate=(tick_rate : Int32)
• #total_frames : UInt64
• #ups : Float64
