Callbacks

Callbacks are functions defined within settings that allow you to define custom behavior of a projectile when certain events occur

Each callback is marked with

• r for direct read permission
• w for direct write permission

There are currently 8 callbacks present

Callbacks

---

OnStep [rw]

Fires every time the projectile steps even if the velocity is 0

OnStep = function(projectile: Projectile, deltaTime: number): nil

---

OnPositionChange [rw]

Fires every time the projectile steps except when the velocity is 0

OnPositionChange = function(projectile: Projectile, newPosition: Vector3, oldPosition: Vector3): nil

---

OnDestroy [rw]

Fires when the projectile is destroyed

OnDestroy = function(projectile: Projectile, reason: string | "MaxTime" | "MaxDistance" | "Hit"): nil

---

OnHit [rw]

Fires when the projectile hits something

OnHit = function(projectile: Projectile, result: RaycastResult, hasPierced: boolean): nil

---

OnTargetLost [rw]

Fires when the projectile exceeds MaxTrackAngle

OnTargetLost = function(projectile: Projectile, target: Vector3 | BasePart): nil

Note

After OnTargetLost is fired, the target is set to nil

---

OnCheckpointReached [rw]

Fires when the checkpoint inside of trajectory is reached

OnCheckpointReached = function(projectile: Projectile, checkpoint: string): nil

Note

After OnCheckpointReached is fired, the checkpoint is set to nil

---

PostTransform [r]

Due to the way Motor6D.Transform works we made a PostTransform callback which is called right after .Transform is applied for the first time. Otherwise the CFrame of the cosmetic part will appear as origin

PostTransform = function(projectile: Projectile): nil

---

PostTransformSafe [r]

This is the 2nd PostTransform. Basically the second time .Transform is applied. This is helpful to safely toggle vfx on or make parts visible to hide the pre .Transform phase

PostTransformSafe = function(projectile: Projectile): nil
