Im using command block on a multiplayer map I am creating. Is there any data value that goes up/down when a player looks in the direction of another player? If not, are you able to count how many players that are on a specific team in a set radius and then say that number through /tellraw?
Yes! There is!
If you're looking to teleport somebody, you can determine the direction that they're looking at with this syntax of the
/tp @p [x] [y] [z] [x-look] [y-look]
If you're looking to select somebody looking in a certain direction, you can use the
rym selector arguments.
For each selector, a float is required as the value to look for. The
rx arguments look for a player with a rotation lower than the given value, while the
rym arguments look for a player with a rotation greater than the given value.
rxmarguments test for the player's horizontal rotation.
-90.0 being that he/she is looking straight down and 90.0 for straight up.
rymarguments test for the player's vertical rotation; whether they are looking North, South, East or West.
This system branches from the South direction (0d) and moves into negative/positive; East (-90d)/West (90d) and North (180d/-180d).
It also allows for in-betweens of multiples of 90 degrees, allowing freedom in testing for certain rotations, for example: 45d is South West.
For example, if I would like to test for a player that is looking North West, and straight ahead (at ground level), I would test for a
rxm of 0 (directly ahead) and a
rym of somewhere between North (180d) and West (90d); 135 degrees.
/testfor @a[rx=0,rxm=0,ry=135,rym=135] ...
Just note, that this command tests for exact rotation, which can be really hard to reach. It'd be better to give leeway either side, for example: 5 degrees.
/testfor @a[rx=5,rxm=-5,ry=140,rym=130] ...
If not, are you able to count how many players that are on a specific team in a set radius and then say that number through /tellraw?
This is also achievable. This time, add the
team selector to your command, and to count, get each player to
/execute @a[...] ~ ~ ~ scoreboard players add dummy count 1, assuming that you have a
dummy player to take the count, have the score set to 0 and your counting scoreboard is
