Since the second-player code was the first code I wrote, it was implemented
poorly. At that point, I didn't know the code base at all and the way it was
written would prevent anyone from ever adding to those parts.
The rewrite allows me to use the default geo.inc.c file for Mario, and removes
all of the geo2.inc.c files. I no longer do a bunch of bit shifting to figure
out which player is being drawn in the rendering code.
I'm also now able to remove tons of duplicate code that exists just for the
remote player. The main player code is generic enough to support both indices.
A side-effect of the rewrite is I was able to remove many assumptions in the
code where two-players is assumed, but many other parts of the code still
assume two players.
This is a fairly major change that, if all goes well, will be completely
unnoticed by the player. However, I do expect new bugs to pop up in strange
places. Time will tell.
Player life counters are separate.
When one player dies they lose a life and are turned into a bubble.
If the other player pops it, they are alive again.
If all players are bubbled, they get kicked out of the level.
If the bubbled player ran out of lives, they can not come back to life
until the level is over.
Whenever a level change happens, everyone's life count is set to a
minimum of two.
No game overs.
Took heavy inspiration from Kaze Emanuar
Players are now solid to each other and can push each other
Players can now attack each other (but they do not deal damage)
Players can bounce on top of each other, and they get squished
temporarily
Players are given slightly offset positions when they transition between
areas and levels, so they're no longer on top of one another.
Synchronized currentRoom per-player
Synchronized haunted bookshelf, and the bookshelf manager
Synchronized haunted chairs
Synchronized mad piano
Synchronized BBH's tilting trap, and made the physics multiple-player-aware
Synchronized scuttlebugs
Synchronized every variety of Boo
Synchronized elevators
Synchronized flamethrowers
Synchronized the various types of enemy books
Synchronized the book switches
Synchronized jumping box
Made coffins multiple-player-aware
Fixed everything that used gMarioState as an array instead of gMarioStates
Prevented some NPC-dialog softlocks
Prevented the remote player from messing up the local's camera settings
Possibly fixed the relatively rare chain chomp softlock
Possibly fixed the relatively rare chain hoot softlock
Fixed the first-person-camera softlock
Forced camera code to use the correct mario struct
Created functions to trivially translate an ID to a Behavior and vice
versa. Sent ID over packets instead of Behavior pointer. This should
allow Linux and Windows to play together.
Added Luigi model.
Renamed all previous references to 'Luigi' to 'Mario2' since player 1
isn't always mario, and player 2 isn't always luigi.
Now server is always mario and client is always Luigi.
Luigi model credits:
Original model by Cjes, converted by AloXado320, textures added/fixed by
SunlitSpace542.
Added maximum sync distance, special cases for infinite distance and
only synchronizing entity deaths.
Started mocking out reliable packets for entity deaths.
along with options to select backends for windowing, rendering, audio and controls in the Makefile
use RENDER_API=D3D11 or D3D12 for the D3D renderers, that will also automatically enable using DXGI for windowing; SDL2 will still be used for input and audio for the time being
also adds three-point filtering to the OpenGL backend and an option for it in the menu
Added a "super responsive controls" cheat. When enabled, Mario will look straight into the direction the user inputs when changing directions, with no interpolation at all. (you can still slide / side jump / etc )
The change is especially noticeable when playing with keyboard.
Enabled a cheat menu. It includes 4 cheats, and all of them rely on the global "Enable cheats" option so the user can quickly turn all the selected cheats off and back on.
