* Player attrs: permits to remove an attribute by setting value to nil
When doing player:set_attribute("attr", nil) remove attribute
Also remove a useless check on C++ API part (already done by checkplayer)
Fix#5709
Recent commit b6f4a9c7e1a4f0bac66fd6f6ff844425ac775975 removed a hardcoded
player collisionbox which resulted on falling back to an incorrect default.
This stopped players walking through 2-node high spaces and made the player
slightly wider.
Improve docs for custom player collisionbox feature and reformat nearby lines.
This unifies the settings APIs.
This also unifies the sync and async registration APIs, since the async
registration API did not support adding non-functions to the API table.
Default true.
Add 'm_clouds_enabled' bool to sky.h, set from new bool in 'set sky' API.
Make 'getCloudsVisible()' depend on 'm_clouds_enabled' instead of
'm_visible' (whether normal sky is visible).
* Optimize updateFastFaceRow processing by removing some TileSpec copy
It permit to decrease this function from 54% runtime to 45% and reduce copy from 14% runtime to 12.5%
getTileInfo also reduced from 27% to 23%
* makeFastFace should use a const ref too
this trigger a const pointer need in the underlying function
Also fix some code style and prevent calculating 4 times the same position at a point
* Reduce a comparison cost for lights in updateFastFaceRow
Instead of create fake events on the stack on each loop call (Game::run), verify is queue is empty or not and handle event directly if there is.
This prevents fake ClientEvent creation & memory allocations
Same fix is also applied on ClientEnvironment, & rename getClientEvent to getClientEnvEvent to match ClientEnvEvent object
Despite the split of TileSpec into TileDef and TileLayer, the
TileLayer struct is still 66 bytes large, and doesn't fit in
a single cacheline.
I'm moving the color member to cacheline 2, in the hope that it
is less used and the compiler loads all the hot members in a single
cacheline instead. Only color sits now in cacheline 2, all the
other members are in cacheline 1.
Note: is_color is probably rarely set, most nodes will likely
not use hardware coloring, but this may change in the future.
Ideally, this class is shrunk to 64 bytes.
