How to get the side position of a player

[LC Creations]

I want to get the side position of a player. I know how to get the position in front of them by this calculation...

Code: Select all

local pos = player:get_pos()
local look_dir = player:get_look_dir()
local distance_away = 5

local pos_in_front = {x=pos.x+(look_dir.x*distance),y=pos.y+(look_dir.y*distance),z=pos.z+(look_dir.z*distance)

....But, I want to get the position to the right (x=positive number) or left (x=negative number) of the player 'x' nodes away... NOT in front of the player, but to the side of the player. Im not good at math so I do not know what to do.

you need to swap the X,Y and Z variables from distance ...
like

Code: Select all

{x=pos.x+(look_dir.z*distance),y=pos.y,z=pos.z+(look_dir.x*distance)

try also to replace some "+" with some "-"

hint: to transform a vextor by a angle x ... you need to use +/-sin() and +/-cos() ... but if x = 90 ... you only need to swap variables because +/-sin() and +/-cos() are -1, 0 or 1 ... i hope ;)

Lets Try&Error xD

ATTENTION: this works only with 2D !!!
this is the reason why Y stay untouched ... but i hope you dont need to transform Y ... because its only you height
