Adds fixed timestep interpolation to the visual server. Switchable on and off with project setting. This version does not add new API for set_transform etc, when nodes have the interpolated flag set they will always use interpolation.

<description>
|
|
Most basic 3D game object, with a 3D [Transform] and visibility settings. All other 3D game objects inherit from Spatial. Use [Spatial] as a parent node to move, scale, rotate and show/hide children in a 3D project.
|
|
Affine operations (rotate, scale, translate) happen in parent's local coordinate system, unless the [Spatial] object is set as top-level. Affine operations in this coordinate system correspond to direct affine operations on the [Spatial]'s transform. The word local below refers to this coordinate system. The coordinate system that is attached to the [Spatial] object itself is referred to as object-local coordinate system.
|
|
[b]Note:[/b] Unless otherwise specified, all methods that have angle parameters must have angles specified as [i]radians[/i]. To convert degrees to radians, use [method @GDScript.deg2rad].

<method name="force_update_transform">
|
|
<return type="void" />
|
|
<description>
|
|
Forces the transform to update. Transform changes in physics are not instant for performance reasons. Transforms are accumulated and then set. Use this if you need an up-to-date transform when doing physics operations.

</method>
|
|
<method name="get_global_transform_interpolated">
|
|
<return type="Transform" />
|
|
<description>
|
|
When using physics interpolation, there will be circumstances in which you want to know the interpolated (displayed) transform of a node rather than the standard transform (which may only be accurate to the most recent physics tick).
|
|
This is particularly important for frame-based operations that take place in [method Node._process], rather than [method Node._physics_process]. Examples include [Camera]s focusing on a node, or finding where to fire lasers from on a frame rather than physics tick.

The [code]target[/code] position cannot be the same as the node's position, the [code]up[/code] vector cannot be zero, and the direction from the node's position to the [code]target[/code] vector cannot be parallel to the [code]up[/code] vector.

Rotation part of the local transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).

|
[b]Note:[/b] In the mathematical sense, rotation is a matrix and not a vector. The three Euler angles, which are the three independent parameters of the Euler-angle parametrization of the rotation matrix, are stored in a [Vector3] data structure not because the rotation is a vector, but only because [Vector3] exists as a convenient data-structure to store 3 floating-point numbers. Therefore, applying affine operations on the rotation "vector" is not meaningful.
