Variants like dictionaries and arrays can have cyclic references, which
caused `encode_variant` to run an infinite recursion.
Instead of keeping a stack and looking for cyclic references which would
make serialization slower, this commit adds a `MAX_RECURSION_DEPTH`
constant to Variant, and have `encode_variant` keep track of the current
recursion depth, bailing when it's too high since this likely means a
cyclic reference has been encountered.
For the time being we don't support writing a description for those, preferring
having all details in the method's description.
Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.
Passing `0` to `enet_host_create` will allow the maximum amount of
channel supported by ENet. For some reasons, `connect_to_host` will
instead only create 1 channel when passed `0`.
This commit normalize the behaviour to always allocate the maximum
allowed channels when passing `0`.
When dragging and dropping a texture, mesh, or scene from the FileSystem into the
2D or 3D viewport, it will be added as a child of the current scene's root node.
* Simplified code a lot, bias based on normalized cascade size.
* Lets scale cascades, max distance, etc. without creating acne.
* Fixed normal biasing in directional shadows.
I removed normal biasing in both omni and spot shadows, since the technique can't be easily implemented there.
Will need to be replaced by something else.
This allows to generate the `VERSION_HASH` constant with the Git commit hash
even when building from a source tarball which is not a Git repository (and
without dependency on Git itself).
`VERSION_STATUS` is part of what constitutes the reference version for a given
Godot build, and is part of the version check for compatible export templates.
For dev snapshots (alpha, beta, RCs), we usually set the `VERSION_STATUS` to
a specific build number (e.g. `beta2`), but this change doesn't end up
committed to the Git repository as we don't want to keep changing `version.py`
for testing builds.
So this new environment override will be what can be used in official builds
and by users making custom builds for specific snapshots.
Used by ENetMultiplayerPeer and WebSocketServer to generate network IDs,
and exposed to the user for p2p networks (e.g. WebRTCMultiplayerPeer)
and custom MultiplayerPeer implementations.
