|
|
// Euler needs to be kept separate because converting to Basis and back may result in a different vector (which is troublesome for users
|
|
// editing in the inspector, not only because of the numerical precision loss but because they expect these rotations to be consistent, or support
|
|
// "redundant" rotations for animation interpolation, like going from 0 to 720 degrees).
|
|
//
|
|
// As such, the system works in a way where if the local transform is set (via transform/basis/quaternion), the EULER rotation and scale becomes dirty.
|
|
// It will remain dirty until reading back is attempted (for performance reasons). Likewise, if the Euler rotation scale are set, the local transform
|
|
// will become dirty (and again, will not become valid again until read).

|

// All this is transparent from outside the Node3D API, which allows everything to works by calling these functions in exchange.

// (to scene, in order to keep the same values and avoid data loss on conversions). It has zero influence in the logic described above.
