Version 1.79 - A-star, sub-Objectives, and Templates

A sizeable update hopefully with something for everyone. Headline features:

A-star pathfinding

This has been available on the Downloads page for a while now, but I'm incorporating this into the official release in an effort to have it be more widely available. A-star 2D is an alternative pathfinding method to the default Polygon Collider, and ought to be a lot faster at handling more complex NavMeshes. If you've previously used the downloadable package, it'd be worth switching over to this as the algorithm has been tweaked further to be a little more natural and faster still.


Objectives can now be linked to one another to create dependencies, where a given Objective can be updated automatically when others are completed or failed. The workflow's a bit involved, though, so a new series of tutorials on this topic can be found here.


The Downloads page mentioned above is getting quite packed now with a lot of handy examples and add-ons, but they can be a bit cumbersome to incorporate into an existing project. To that end, Templates - where such add-ons can be installed with a single click - will begin to be rolled out. By way of example: the "Shop system" package previously required manually adding Inventory properties, categories, and Menus, but the updated package now provides a handy "Apply" button that will automate these changes for you. Templates can also provide example scenes, and custom prefabs for the Scene Manager.

Eventually, the Template system will be incorporated into AC proper, but for now it's in use by the following Download packages:

  • First Person player
  • 2D First Person
  • Click FX
  • Isometric Camera
  • Nine verbs interface
  • Mobile joystick
  • Save-game screenshots
  • Save-game retro
  • Conversation camera
  • Speech bubbble
  • Cinemachine integration
  • Shop system

  • Man, what an update. Not only the much needed feature for having custom names for addressables is in it, but I recently thought about asking for an Action that let's you check which camera is currently active and it's in there, too.
    And you have no idea how much the "Ignore presets" checkbox just saved my life. It's almost like you read my mind. Thank you very much for this one. Basically every AC update is a gift, but this one especially.

  • A few issues slipped through the cracks, a hotfix to address them:

    Version 1.79.1:

    • Fixed: "Object: Animate" Actions in ActionList asset files breaking the ActionList Editor window
    • Fixed: Error viewing save data in the Save-File Manager when "Compress save files?" is checked
    • Fixed: Incorrect character placement when the "Character: Move along path" Action is skipped
    • Fixed: NavMesh Agent Integration component causing a rotation issue
    • Fixed: "Sprites 2D Toolkit" remaining as an "Animation engine" option despite being deprecated
  • Thank you so much for the update! There are so many amazing new features, and I'm especially excited about the New Sub Objective feature.

  • Excellent work, Chris!

    The subobjectives look very interesting indeed, they seem simple enough on the surface but open up some quite interesting and complex behaviours.

    First things first, how do I make some free time between fighting to keep the lights on and sleep.
