Inspired by [LibGDX actions](https://github.com/libgdx/libgdx/wiki/Scene2d#actions). Represents a `monoid`. This approach also lends itself to manipulation by higher order functions (similar to parser combinators).\n\n## Example\n```lua\nlocal Actions = require \"actions\"\nlocal Timer = require \"hump.timer\"\n\nlocal objectA = {val = 0}, objectB = {val = 0}\nlocal action = Actions.Sequence(\n\tActions.Print(\"Started action...\"),\n\tActions.Wait(3),\n\tActions.Print(\"3 seconds passed...\"),\n\tActions.Parallel(\n\t\tActions.Tween(3.0, objectA, {val=10}, 'linear'),\n\t\tActions.Tween(2.0, objectB, {val=10}, 'linear')\n\t)\n)\n\n--[[ Play the action by calling it as a function.\nThe first argument is the Hump.Timer object used to run\nevents, and the second argument is a continuation to\nbe run on the completion of the action. ]]--\naction(Timer, function()\n\tprint(\"Continuation...\")\nend)\n```\n\n## Documentation\n### Action Primitives\nThese functions return actions that, when played, will do something.\n#### `Actions.Empty()`\nAn empty 'identity' action which does nothing.\n#### `Actions.Wait(duration)`\nAn action which waits for the provided amount of seconds.\n#### `Actions.Do(func)`\nAn action which invokes the provided function, then continues.\n#### `Actions.Print(func)`\nAn action which prints to the console.\n#### `Actions.Tween(duration, subject, target, method, ...)`\nTweens an object. See [Timer.tween](https://hump.readthedocs.org/en/latest/timer.html#Timer.tween) for more details.\n\n### Combinators\nCombinators take in actions, compose them, and return new actions that can be further composed.\n#### `Actions.Sequence(...)`\nTakes in a variable number of actions, and returns a new action which plays them all in sequence.\n#### `Actions.Parallel(...)`\nTakes in a variable number of actions, and returns a new action which plays them all in parallel. The continuation is invoked when\n\n### Creating a Custom Action Primitive\nPart of what makes this approach effective is that you can create your own Action primitives. Here are some examples.\n\n```lua\nfunction Actions.PlaySource(source)\n  return function(timer, cont)\n    love.audio.play(source)\n    cont()\n  end\nend\n\nfunction Actions.DestroyEntity(entity)\n  return function(timer, cont)\n    entity:destroy()\n    cont()\n  end\nend\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frameshvarun%2Fhump.timer.actions","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frameshvarun%2Fhump.timer.actions","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frameshvarun%2Fhump.timer.actions/lists"}
