* Android: Replace movement buttons with joystick
Replace movement control buttons (arrows at bottom left screen) with virtual joystick.
Joystick has 8 directions (same as keyboard). Basically, just map it to keyboard input.
Joystick applies only on left 1/3 of screen.
Joystick's position can be fixed by enabling fixed_virtual_joystick setting.
Three new images:
(1) placeholder joystick,
(2) joystick container (background), and
(3) joystick cursor.
Remove unused images: movement control buttons (*_arrow.png).
New data type: touch_gui_joystick_move_id
Joystick's fixed position is spaced one button size from bottom and from left of screen.
Remove unused variable: m_joystick_downlocation
Necessary for placing the base cube of 'plantlike_rooted' drawtype in the
seabed instead of on it.
Useful for placing decorations sunk into, or buried in, the ground.
Add 'biome_zero_level' argument to 'generateBiomes()', 'deco_zero_level'
argument to 'placeAllDecos()' and 'ore_zero_level' to 'placeAllOres()'
to allow mapgens to vertically shift the registered biomes, decorations
and ores per-mapchunk.
Will also allow many realm possibilities in future mapgens.
• Prevents conflicts with custom subgames/mods that could have a different gui_formbg.png.
• This texture should not be used outside of the engine and minimal subgame to ensure backwards-compatibility.
• (Hopefully temporarily) switch to my minetest_game fork, that removes binoculars (it currently doesn't work with minetest-luk3yx-4 0.4.19), and fixes the player collisionbox offset.
This commit introduces Raycast, a Lua user object, which can be
used to perform a raycast on the map. The ray is continuable, so one can
also get hidden nodes (for example to see trough glass).
A useful function that applies 'core.is_protected()' to a 3D lattice of
points evenly spaced throughout a defined volume, with a parameter for
the maximum spacing of points.
• Implements https://github.com/minetest/minetest/pull/7099 in a backwards-compatible way.
• Formspec prepends are appended (I don't think prepending them works) to formspecs before sending them to clients. This way older clients will still be able to display formspec prepends.
* Do not always show every depends textfieds
When there are no dependencies, it does not longer show an empty list.
* Adjust the list height to avoid a scrollbar when possible
* change minimum height and no dependencies message
* Do not get depends for modpacks
The "what" parameter is being passed by value, most likely by
accident as the type is "const std::string". Convert it to a
reference by adding the missing "&".
