Join your world and server already a beeg or a tiny by specifying your preference in your Client Config
Join servers as a beeg by setting preferablyBeeg to true. This will be the size of beeg players according to the world you are joining, so it is possible you will just be normal size among tinies if giants are disabled. The point is that you will be bigger than others where possible.
Similarly, join servers as a tiny by setting preferablySmol to true. This is the size of tinies according to the world, and you might just be a normal-sized player among giants if low scales are disabled. The point is that you will be smaller than others if possible.
Configure your choices in your Client Config:
actuallysize-client.toml
# You will join servers as a beeg
preferablyBeeg = true
# You will NOT join servers as a beeg
preferablyBeeg = false
You can enable both, but being beeg takes precedence. You'd only be a smol if the server has beegs disabled.
# You will join servers as a smol
preferablySmol = true
# You will NOT join servers as a smol
preferablySmol = false
If you really want to you can change your preferred scale to a specific number. Choosing any number other than 1 will enable this, and it takes precedence over the two options before for servers that have it enabled.
# You will join servers as a 4 blocks tall minigiant
preferredScale = 2
# You will join servers as a speck A HUNDRED TIMES SMALLER than normal people
preferredScale = 0.01
Players can choose if they are big or smol, but the actual scale is chosen in your Server Config:
actuallysize-server.toml
# The default value, beegs are 8X the size of normal players
beegSize = 8
# This disables this feature and players will not join as beegs
beegSize = 1
# The default value, tinies are roughly two pixels tall ~ 1/8 of the normal size
tinySize = 0.13
# This disables this feature and players will not join as tinies
tinySize = 1
It is easiest to have specific beeg or tiny sizes, and having people choose their own size is often cahotic.
# Allow players to join any size they want
allowFreeSize = true
# Do not allow players to use the "preferred scale" config option.
# But beeg and smol options still work, they can just use those.
allowFreeSize = false
