8 terminate after <n> frames
11 terminate after <t> milliseconds
13 if both n and t are given, terminate after n frames and
14 assume <t> milliseconds pass each frame
17 load assets from given path
18 default is application dir + "assets"
21 store and load saves at given path
22 default is whatever SDL thinks is good
23 (should be ~/.local/share/localhorst/blank/)
29 disable double buffering
32 set sample size to <num> (samples per pixel)
38 run as standalone (the default)
50 disable keyboard input handling
53 disable mouse input handling
56 disable HUD drawing (includes the selected block outline)
60 the audio device and sounds will still be allocated
61 it just stops the interface from queueing buffers
67 hostname to connect to in client mode
70 port number to connection to (client) or listen on (server)
76 use <seed> (unsigned integer) as the world seed
77 only used for newly created worlds
81 use given name for the world save
82 no checks are being done right now, so make sure it can be
83 used as a directory name
89 Move around with WSAD, shift, and space, look around with mouse motion.
90 Mouse button 1 deletes the block you're pointing at, button 2 selects it
91 as the active block, and button 3 places the active block next to the one
94 As an alternative to picking, you can also use the mousewheel up/down to
95 flip through available blocks.
97 Q changes the face of the active block (loops over up, down, right, left,
98 front, and back) and E changes the turn (none, left, around, and right).
100 Pressing B prints details about the block you're pointing at and P prints
101 info about the active block. L spits out the player position and light
102 level there. C dumps info about the chunk of the pointed at block.
104 Press N to toggle player/world collision.
106 F1 toggles UI rendering.
107 F3 toggles a display telling how long on average it takes to compute a frame.
110 Controls are interpreted by scancode, meaning you don't have to break your
111 fingers when you're on an AZERTY. WSAD will be ZSQD there and the above
112 description is just wrong.
114 Also I've added a plethora of alternate keys that can be used, like arrow
115 keys for movement, ins/del for placing/removing blocks, etc.
