Fixes #66964
Bezier animations weren't being properly converted to from Godot 3.x to 4.x, raising errors such as
Condition "!d.has("handle_modes")" is true. Returning: false
. This seems to be because 4.x expected aHandle Mode
to be defined for each individual key, whereas in Godot 3.x seems to have the Handle Mode as an Editor setting. When Godot 4.x opened a Godot 3.x project, it looked forhandle_modes
that weren't there, and failed when it couldn't find them. To fix this, I've changed it so that ifhandle_modes
is not defined, they are all initialised to 0. (This corresponds toFree
is also the default when creating animations in the Editor)This fix should make it a lot easier to import Bezier animations from Godot 3.x to 4.x.
