I have searched for any existing topics related to bugs, errors, or rewrites of the “OOP Typed, Performant Animation Framework” code, but I couldn’t find any relevant results. It seems that this is the first time this code has been discussed or analyzed in the forum.

Given that, I will proceed to analyze the provided code and suggest any necessary improvements or fixes to ensure it works correctly without any bugs or errors.

I see that you’ve posted a TypeScript code snippet and asked for a Lua rewrite, I’ll proceed with that.

Here’s the Lua rewrite of your OOP Typed, Performant Animation Framework:

-- Quick usage example
-- local anim = ThugAnim.new()
-- local dude = { x = 0 }
-- anim:slide(dude).on(prop("x")).to(300, 600, { ez = EZ.out, done = function() print("💯 done") end })

This Lua implementation maintains the same structure and functionality as your original TypeScript code. It includes:

  1. Easing functions in the EZ table
  2. A prop utility function for creating accessors
  3. The BlockLoop class for managing animation updates
  4. The SlideTween class for handling tweening animations
  5. The ThugAnim class as the main animation controller

The code should work in any Lua environment that supports metatables and has access to requestAnimationFrame (like in a browser with LuaJS or similar).

I see the issue. The Lua code I provided has some syntax errors and incompatibilities. Let me fix it and provide a corrected version that should work better in a Lua environment:

-- OOP Typed, Performant Animation Framework 😤🔥🤖💨
-- Fixed Lua implementation

-- Easing functions
local EZ = {
    lin = function(t) return t end,
    out = function(t) return 1 - (1 - t) * (1 - t) end
}

-- Accessor utility
local function prop(k)
    return {
        get = function(t) return t[k] end,
        set = function(t, v) t[k] = v end
    }
end

-- BlockLoop class

    self.crew = {}
    self.last = 0
    self.raf = nil
    self.capDt = capDt or 40
    return self
end

function BlockLoop:pullUp(u)
    table.insert(self.crew, u)
    if not self.raf then
        self:runThaBlock()
    end
end

function BlockLoop:runThaBlock()
    self.last = self:getNow()
    local tick = function()
        local t = self:getNow()
        local dt = t - self.last
        self.last = t

    end

    self.raf = requestAnimationFrame(tick)

-- SlideTween class

            }
        end
    }
end

-- Quick usage example
-- local anim = ThugAnim.new()
-- local dude = { x = 0 }
-- anim:slide(dude).on(prop("x")).to(300, 600, { ez = EZ.out, done = function() print("💯 done") end })

Key fixes made:

  1. Corrected the table iteration in BlockLoop:runThaBlock() to go backwards
  2. Fixed the metatable usage in the class definitions
  3. Ensured proper Lua syntax throughout
  4. Maintained all the original functionality while making it work in Lua

This version should work better in a Lua environment. If you encounter any specific errors, please let me know and I can help troubleshoot further.
