Exposes the "interpolated" flag on nodes via a property, physics_interpolation_mode.
Mode can be INHERIT, OFF and ON. This makes it easy to turn off interpolation for nodes in the editor, versus via code.
References to "idle time" are progressively being replaced by
"process time" throughout the engine to avoid confusion.
This also changes some debug prints to be printed only when verbose
mode is enabled (like in `master`).
This feature makes it possible to workaround problems such as:
- long baking time due to heavy synchronization when parsing geometry
from mesh instances
- crash when freeing `NavigationMeshInstance` while baking
- errors when actively baking node tree is being detached from the
scene tree
Leftover transforms from the physics tick were being flushed during idle, which was causing problems for physics interpolation.
This PR flushes the transforms at the end of the physics tick when physics interpolation is active.
This makes it possible to create more aesthetically pleasing
styleboxes for GUI theming, especially in games that have
a futuristic appearance (where skewed buttons and progress bars
are common).
The data flow to the VisualServer of current and previous transforms is essential for allowing correct interpolation. An optimization was present that disabled sending transforms when nodes were hidden, however this meant that when unhidden, nodes would interpolate incorrectly from the last transform received when hiding, rather than the up to date previous transform.
This PR disables the optimization and sends always sends transforms when a node is interpolated.
When switching emission on and off, processing was always being switched on and off using internal_process, which was incorrect for using physics interpolation (where physics_process is the relevant one).
This PR correctly updates the process mode according to whether physics interpolation is being used.
Zero or negative ratios are not valid, so the property hint prevents
choosing such values.
The property hint allows using 4 decimals so that common aspect ratios
like 16/9 can be specified with a good level of precision.
Bug problem:
No condition for when the first character of the label is a space character
Fix:
Added an IF condition for when the first character is a space character
The autowrap boundary treat this space character as another dummy word in the WordCache linked list and proceed to function normally, by detecting when line width is 0
