fivem.shared.util.Quaternion

A rotation quaternion, layout-compatible with what GET_ENTITY_QUATERNION / SET_ENTITY_QUATERNION expect.

Most gameplay code should stay in Euler degrees (Entity.rotation), since that's what the game itself exposes. Reach for quaternions when you need interpolation that doesn't gimbal-lock — smooth camera swings, attached object alignment, or blending between two orientations over time.

Euler conversions here use the game's ZXY convention (pitch = X, roll = Y, yaw = Z), matching GET_ENTITY_ROTATION with rotation order 2.

Static variables

`staticread onlylength:Float`

Static methods

`staticinlineconjugate(this:QuaternionData):Quaternion`

The inverse rotation (valid for unit quaternions, which is all this class produces).

`staticinlinecopy(this:QuaternionData):Quaternion`

`staticinlinedot(this:QuaternionData, rhs:Quaternion):Float`

`staticfromAxisAngle(axis:Vector3, degrees:Float):Quaternion`

Builds a rotation around axis (which is normalized first) by degrees.

`staticfromEuler(rotation:Vector3):Quaternion`

Builds a rotation from Euler angles in degrees (pitch, roll, yaw), ZXY order.

`staticinlinefromHeading(degrees:Float):Quaternion`

A yaw-only rotation matching a game heading in degrees.

`staticinlinefromNative(value:Dynamic):Quaternion`

`staticinlineidentity():Quaternion`

The do-nothing rotation.

`@:op(A * B)staticmul(this:QuaternionData, rhs:Quaternion):Quaternion`

Composes two rotations: a * b applies b first, then a.

`staticinlinenormalized(this:QuaternionData):Quaternion`

`staticrotate(this:QuaternionData, point:Vector3):Vector3`

Rotates a vector by this quaternion.

`staticslerp(this:QuaternionData, target:Quaternion, t:Float):Quaternion`

Spherical interpolation towards target. Unlike lerping Euler angles, this always takes the shortest arc and keeps a constant angular speed.

`statictoEuler(this:QuaternionData):Vector3`

Converts back to Euler degrees (pitch, roll, yaw).

`staticinlinetoString(this:QuaternionData):String`
