1.7.0 update :

- Editor : Fixed float fields so various editors no longer throw errors in Unity 6000.0.

- Scripting API : All BulletModules no longer inherit from UnityEngine.Object. This solves issues related to DontDestroyOnLoad for bullet persistence between scenes.

1.6.0 update :

- Overall : Ensured BulletPro is fully compliant to the latest changes up to Unity 2023.2 and 6000.0b.

- Gameplay : Improved GPU collision detection between two line-shaped colliders.

- Graphics : Fixed the way values from a TextureSheetAnimationModule are copied into a BulletVFX. Particle Systems can now safely have their animation module set to Sprite mode.

- Editor : Improved display of bullet hitboxes in the Inspector.

- Editor : Bullet sprite is now able to preview sprites when the graphics are picked from “List of possible values”. (Props to Kasei for finding out)

- Bugfix : Fixed shot layout recalculation when used with a dynamic parameter. (Props to JackLei for finding out)

1.5.1 patch :

- Docs : User manual and Quickstart Guides fully updated with up-to-date screenshots, thanks to Rick Elliott!

1.5.0 update :

- Overall : Ensured BulletPro is fully compliant to the latest changes up to Unity 2022.2 and 2023.1b.

- Bugfix : Collision system now correctly takes the absolute size of bullets attached to an external parent that has been scaled. (Props to Sirono for finding out)

- Scripting API : The BulletModulePatterns class now has a way to count totalShotsFired and totalBulletsEmitted, for ammunition-counting purposes. The totalShotsFiredRecursive and totalBulletsEmittedRecursive properties can also handle fired bullets that fire bullets.

- Scripting API : BulletModulePatterns.ShootBullets() now returns the number of emitted bullets. BulletModulePatterns.EmitSingleBullet() now returns the bullet.

- Scripting API : In Bullet Behaviours, the OnBulletShotAnotherBullet() callback now triggers right after the Shot has been fired, and not just before.

1.4.0 update :

- Graphics : A new "Color Filter" shader is available for bullets. It adds an extra tint to the bullet after the bullet's "native" color.

- Graphics : You can now set a bullet's Layer, for post-process purposes.

- Graphics : Particle Systems now unparent themselves from a bullet right after it dies.

- Gameplay : BulletBehaviours are now created last when a bullet gets fired, and processed first when the bullet dies. This way, all references to modules in user-made scripts are always valid.

- Editor : Use of PrefabUtility is now compliant with the latest API changes from Unity 2021.2.

- Editor : When a Shot cannot accurately calculate its potential number of bullets, you can now choose how many bullets should be shown in the preview.

- Bugfix : Fixed an issue where the number of bullets contained in a Shot could not be made equal to another dynamic parameter.

- Bugfix : Dynamic Parameters relative to a Pattern's state now behave properly when the same Emitter has two sibling Patterns.

- Bugfix : A bullet's local scale is now refreshed in the same frame it is fired. This solves artifacts that could happen with bullets fired by other bullets.

- Scripting API : Movement Module now has a public function for manually refreshing an object's scale.

1.3.1 patch :

- Gameplay : Patterns now have a base delay between each instruction. It can be freely disabled or modified at runtime, and it can exclude some instructions.

- Editor : All the recent Pattern features are now under an "Advanced Settings" foldout.

- Editor : Bullet, Emitter and Receiver default gizmo colors are now globally stored in your Project Settings (BulletProSettings). They can still be changed individually.

- Editor : Gave more accuracy to pool size adjustment buttons: +10, -10, +1, -1.

- Bugfix : Bullet Asset VFX module inspector no longer throws errors in old versions of Unity.

- Bugfix : Movement Module's LookAt function now properly behaves in all non-XY rotated planes.

1.3.0 update :

- Graphics : When a collision happens between a Circle Bullet and a Circle Receiver, impact point calculation now accounts for every offset and scale modifier.

- Gameplay : Patterns now have the "Compensate Small Waits" option. If enabled, it allows to account for time steps smaller than one frame.

- Gameplay : Patterns now have the "Delta Time Displacement" option. If enabled, it will offset the spawn position of their children bullets to achieve pixel-perfect layouts. This effectively cancels any loss of accuracy from short Wait durations.

- Gameplay : Four new Pattern Instructions now allow for full manipulation of Random Seed, most notably by freezing/unfreezing it at will. While frozen, a random seed will not auto-reroll itself, but can be manually rerolled at any time.

- Gameplay : Homing bullets are now able to switch to Predictive Mode, which aims at a specific point that is calculated from target's speed and direction. The old mode (directly aiming at current target position) is now called Standard Mode.

- Scripting API : Homing Module and Movement Module have new public functions to ease calculations for intercepting moving objects. (The same functions used in Predictive Mode)

- Scripting API : Demo scripts now have their own namespace, thus preventing conflicts with non-BulletPro scripts upon importing the package.

- Bugfix : Getting a Bullet Behaviour Prefab from its pool no longer fails if the prefab is part of the Addressable Asset system.

- Bugfix : BulletEmitter.PlayPatternTag() can now fail due to its root bullet being unavailable, and this can no longer yield a gameplay-breaking exception.

1.2.3 patch :

- Graphics : Particle Effects can now be attached to a bullet whose scale starts at zero, and behave normally afterwards.

- Gameplay : New Pattern Instructions now allow to change a bullet's Custom Parameters without the need of additional code.

- Scripting API : New MicroActions are available for changing parameters over time.

- Editor : Fixed the color of Bullet Module buttons in Light Theme.

- Editor : The BulletEmitter Component now has a proper Gizmo.

1.2.2 patch :

- Gameplay : The collision system now fully supports negative scale values on any Transform.

- Bugfix : Fixed a rare issue that could throw errors while opening the AsteroidSpawner sample asset.

1.2.1 patch :

- Bugfix : Fixed an issue where the Bounce() function had unwanted behaviours when a wall was at exactly 90 degrees.

- Editor : BulletReceiver gizmo is no longer showing if the component is disabled.

- Scripting API : BulletBehaviours now have their Awake() function marked as virtual, so it can be overridden in user-made scripts.

- Scripting API : BulletBehaviours now have a "Start Isolated From Bullet" boolean, which enables using behaviour prefabs without having to embed them into a bullet.

1.2 update :

The 1.2 version introduces many features that focus on VFX and Particle Systems. Every bullet can now be rendered as a Particle System, and every parameter from Shuriken can be linked to bullet data.

Extra gameplay features and QoL additions are also included.

Since the changelog is longer than usual, it can be found at this link.

1.1.4 patch :

- Bugfix : Bullet Sprite preview in the Collision module can no longer throw errors when the whole animation frame list gets deleted.

- Scripting API : BulletEmitter.cs no longer throws warnings when trying to call control functions (like Play, Pause or Stop) before its Start frame. Instead, those function calls get saved, delayed and applied right after Start.

1.1.3 patch :

- Bugfix : Creating a new EmitterProfile asset from the Project folder no longer throws errors in Unity 2020.3 and onwards.

- Bugfix : In EmitterProfile assets, deletion of BulletHierarchy elements no longer throws errors in 2021.1, and no longer triggers unwanted second deletions.

1.1.2 patch :

- Gameplay : BulletReceiver Component now properly supports advanced events in the form of OnHitByBulletEnter/Stay/Exit, with multiple bullets per frame.

- Editor : Advanced events are now accessible from the inspector of the BulletReceiver Component.

- Scripting API : BulletVFX.cs is now friendly to the Unity 2021 API changes to ParticleSystem.

1.1.1 patch :

- Bugfix : Functions related to Pattern Tags (like PlayPatternTag()) no longer throw an error when called at Start.

- Scripting API : Explicitly calling BulletEmitter.Play() during its Start frame is now possible. If another function (like Pause or Stop) cannot be called at Start, the console will output a clearer warning message.

- Editor : When a Dynamic Parameter is in the new "Equal to another parameter" mode, if it belongs to a Pattern, its Reroll Frequency can now be edited.

1.1 update :

- Bugfix : Dynamic Parameter Window no longer throws an error when closed by selecting another GameObject.

- Bugfix : In Unity 2020.2, 2D packages and 2D templates no longer prevent you from creating new EmitterProfile assets.

- Bugfix : When two Line Colliders intersect, the exact impact position is now correctly transmitted to the callback.

- Gameplay : Dynamic Parameters have a new mode called "Equal to another parameter", where they can directly follow any Custom Param or Global Param.

- Editor : During Play Mode, it is now possible to see an emitter's Root Bullet through its inspector.

- Scripting API : Added support for global parameters of type Gradient, through the GetGradient() and SetGradient() functions in BulletGlobalParamManager.

- Scripting API : The BulletEmitter component now has a direct access to its Root Bullet, see the following example:

Bullet b = GetComponent<BulletEmitter>().rootBullet;
