Vectors
%vectors% rotated around (x|y|z)-axis by %number%
%vectors% rotated around %vector% by %number%
Locations
%locations% rotated around (x|y|z)-axis at %location% by %number%
%locations% rotated around %vector% at %location% by %number%
Rotates a list of locations or vectors around an axis by an angle in degree.
Effect of the axis vector on the rotation
| Rotation | Direction Vector |
|---|---|
| clockwise rotation around x-axis | 1, 0, 0 |
| clockwise rotation around y-axis | 0, 1, 0 |
| clockwise rotation around z-axis | 0, 0, 0 |
| anti-clockwise rotation around x-axis | -1, 0, 0 |
| anti-clockwise rotation around y-axis | 0, -1, 0 |
| anti-clockwise rotation around z-axis | 0, 0, -1 |
Obligatory example:
set {_line::*} to line with length 1 and density 5
set {_rotated::*} to {_line::*} rotated around y-axis by 180
With locations:
set {_line::*} to line from player to location 1 in front of player with density 5
set {_rotated::*} to {_line::*} rotated around y-axis at player by 180
Rotates the line around the y-axis by 180 degrees as shown in the image (green particles = original, flame particles = rotated):
Note that the rotation goes clockwise. If you want an anti-clockwise rotation you have to use a negative angle. If you want to rotate around another axis than the x-, y- or z-axis you have to get a vector along that axis.
Example:
set {_line::*} to line with length 1 and density 5
set {_rotated::*} to {_line::*} rotated around vector 1, 1, 1 by 180
Note that this is not the same as:
set {_line::*} to line with length 1 and density 5
set {_rotated::*} to {_line::*} rotated around x-axis by 180
set {_rotated::*} to {_line::*} rotated around y-axis by 180
set {_rotated::*} to {_line::*} rotated around z-axis by 180
