1.2.1

AI Skills - Now you can use Claude Code or other AIs with or without Unity AI (MCP) to create, manage, and code with Projectile Factory. Skills include creating new behaviors and setting up new Projectiles from particles.

1. Install Claude Code or Cowork.

2. Run the bundled install.sh in your project.

3. Open your agent and ask it to build projectiles in plain English.
4. Verify step: Ask 'What can you do with Projectile Factory?' to confirm it's active"

1.2

IMPORTANT: If your own scripts live in an Assembly Definition, add a reference to

MagicPigGames.ProjectileFactory (and MagicPigGames.Shared). No changes needed if

you don't use asmdefs.

* Added Assembly Definitions for Projectile Factory, the demos, and the new MagicPig Shared folder.

* All components now derive from a new MagicPigMonoBehaviour base class, and the custom inspector only targets those.

* [Pooling] Big cleanup: fixed objects being returned to the pool twice, pooled projectiles respawning with the wrong rotation, stale Launched/target state on reuse, and several leaks where behavior, observer, and spawn modification instances weren't destroyed between shots.

* [Projectile Spawner] The pre-launch trajectory is now stored on the spawner instead of the projectile prefab. Two spawners sharing the same projectile no longer fight over it, and the prefab no longer gets dirtied in the editor.

* [Behaviors] Fixed homing turning speed (it was instant no matter the max angle), wave motion changing with frame rate, FindNewTarget destroying the projectile even after finding a target, bounce direction on CollisionSpawnObjectAndBounce, and a divide-by-zero when spawning a single projectile with spread angles set.

* [Editor] Undo works in the exposed-fields editor, enum fields display properly, asset scans now only run when needed (faster compile/play), and "Remove Colliders" edits prefabs safely with a confirmation dialog first.

* Removed a using directive that broke compilation on .NET Standard 2.1 (the Unity 6 default).

* Performance pass: non-allocating physics casts, cached materials and shader IDs, and removed Debug.Logs from hot paths.

* Fixed GetWorldPosition for projects set to the new Input System only.

* Updated deprecated FindObjectOfType calls for Unity 6.1+.

* Lots of smaller fixes and dead code cleanup across behaviors, observers, demos, and the inspectors.

1.1.4

* Updated to use new Input system

* Updated 6.3 version to default to URP for demo scene.

1.1.3

* Updated SpawnObjectOnTriggerOrCollision to add a Vector3 offset. The DirectionOfHit variant uses the value in relative space to the direction of hit.

1.1.2

* Minor fixes

1.1.1

* Minor updates to prefabs and scripts from yesterdays larger update.

1.1

* Added option to sendCollisionEvent to the hit objects when using the ProjectileRaycastHitDetector behavior, CollisionAtLineRendererEnd, and the instantHitForward behavior. See docs here.

* Updated to Unity 6.x

1.0.30

* Fixed a delay issue on some Scriptable Objects

1.0.29

* Fixed a prefab in the demo with missing components

1.0.28

* Removed some debug.logs that snuck into production.

1.0.27

* Fixed a bug where events on newly spawned projectiles were being overwritten by empty events after being copied.

1.0.26

* Put the LayerField property Attribute into the MagicPigGames namespace.

1.0.25

* Updated ProjectileUtilities to fix a bug in the SetLayer method.

1.0.24

* Updated Projectile.cs to fix an edit-time issue that kept the values of Projectile Data from being updated in the Inspector, even though they were being updated on the Scriptable Object.

1.0.23

* Moved the LayerAttributeDrawer script to the proper location (in Shared Files)

1.0.22

* Variety of updates to the shared files to support the latest Game Modules 4 updates.

1.0.21

* [Projectile] Fixed a bug where new projectile classes would cause an Inspector error.

1.0.20

IMPORTANT: The change below may require some code updates, if you're calling projectileData from your scripts! Call the property "ProjectileData" instead.

* [Projectile] Made the field projectileData private, and added a ProjectileData property that leads to an instance of the Projectile Data object assigned in the Inspector.

* Updated the SpawnBehavior Property to use an instance of the scriptable object. (No scripting changes should be required for this)

1.0.19

* [Scripts] Moved two scripts between the Demo folder and main, which were in the wrong place. Also updated the name of SpawnerIsActorDamageObserver to be SpawnerIsActorDamageObserverDemo

* Magic Time: Updated integration scripts

1.0.18

* Magic Time: Added integration for Magic Time - Local Time Scales!

* [Projectile Spawner] Added option (false by default) to set the layer of projectiles when they are launched. Useful if you need to separate out projectiles so they don't hit friendlies in your project.

* Added an option to ProjectileSpawner that, when true, forces projectile spawn point to turn toward the target at launch. It is false by default.

* [Pool Manager] Fixed a bug where some objects, if their parent were destroyed after starting the return to pool Coroutine, would throw an error.

1.0.17

[Game Modules 4 Integration] Scripting docs with walkthrough and video

- Projectile Factory and Game Modules 4 are easily integrated. Files required to enable this have been added to each package.

1.0.16

* Fixed TWO bugs where events were being replaced.

1.0.15

* Fixed a small bug in the ForwardWithSpeedCurve movement behavior that caused the change ramp to repeat when it wasn't meant to.

1.0.14

* Added a "Runtime Test" section to the Projectile Spawner inspector, with buttons to start/stop spawning and previous/next projectile.

1.0.13

* Fixed bug in ToggleTrailRendererObjectsDestroyAndLaunchObserverObject to ensure all objects in the list are toggled properly.

* Updated DestroyOrPoolObjectsWithFade to correctly handle gradients in the start color value of particles.

1.0.12

* Fixed a bug where some behaviors weren't being deleted (they were, but would show up again if you pressed "play" very quickly)

* Moved some files around, out of the demo folder

* Added a helper tool: Window/Projectile Factory/Helpers/Projectiles Quick Editor

- Select multiple projetiles. Any "Behavior" or "Spawn Behavior Modification" attached will show up in a list. You can remove each one from any of the selected Projectiles that have them, or select a new Behavior/Spawn Behavior Modification from a list and "Add to all". Or, for each one on the objects "Replace with" the object from the list. This makes it easy to batch-edit many many projectiles at once.

1.0.10

* Added more options for "Best Match" & fixed one bug with that feature.

1.0.9

* Added a "Best Match" feature when adding Behaviors & Spawn Behavior Modifications that will give a button to add the object that best matches the Projectile object name. With naming standards, this makes it a bit easier to add the unique Impact & Muzzle behaviors to the Projectiles. Helpful when converting Asset Store particle packs or setting up dozens of Projectiles at once.

1.0.8

* Added a "Helper" menu option to remove all colliders from the selected prefabs and their children. Useful when integrationg a Particle package from the Asset Store which has colliders on the objects, if you don't want to use colliders for collision detection. (I.e. when you plan on using a raycast check for the hit)

1.0.7

* Added a "Helper" menu option to turn off the "Auto Destruct" on trails of all selected objects. This is useful when integrating a Particle package from the Asset Store which has trails.

1.0.6

* Fixed a bug with pre-launch trajectories not getting the ProjectileSpawner set properly.

1.0.5

* Updated SpawnProjectile method to include an optional GameObject newProjectile -- if included, this projectile will be set and spawned instead of the current projectile. If it doesn't yet exist in the Projectiles list, it will be added.

* Updated ProjectileSpawner SetProjectile method to include an optional bool to add the Projectile (GameObject) if it isn't in the list. true by default.

1.0.4

* Update to InstantHit collision behavior to ensure the raycast comes from the just-used SpawnPosition in situations where there are multiple Spawn Positions.

* Updated LineRendererLength.cs so that if no hit is detected, the line reverts to the max distance, rather than the last cached distance

* Added LookAtLastCollisionPoint behavior, which will force a projectile to look at the last point of a collision. Useful for beams that are parented to the spawn point, and you don't want the hit point to move even if the spawn point moves.

* Added the concept of the SpawnerObserverObject which is similar ObserverObject but for the Projectile Spawner.

* Added SpawnerLifecycleActionsObserverObject to handle lifecycele events on the ProjectileSpawner, derived from SpawnerObserverObject

1.0.3

* Removed an unused declaration that caused some versions of Unity to not build.

* Made the "Toggle target motion" and "Speed" UI elements in the demo scene affect all targets, not just the ground target.

* Made an update to the SpawnBehavior addressing groups of projectiles shot at once to ensure they're shot from the same spawn point in certain conditions.

* Fixed an Inspector error when attempting to expand/inspect objets that are null.

* Updated the InstantHit Collision Behavior

1.0.2

* Added a helper method: Window/Projectile Factory/Helpers/Set Layer of all Projectiles which will allow you to quickly change the layer of ALL prefabs with a "Projectile" component to the layer you choose (probably the "Projectile" layer). This is useful since the "layer" setting for each Projectile is not shipped with the project, and layers must be set up by you (scripts can't do it). After importing the package or any integration, this option will set up ALL the projectile quickly.
