@Name ( " Location Scale " )
@Description ( " Scales locations from a center by a scaling factor. The direction parameter adds an additional scaling along the x-, y- and z-axis. " )
@Examples ( { " set {_circle::*} to circle at player with radius 1 and density 5 " ,
" set {_bigcircle::*} to {_circle::*} scaled at player by 2 " ,
" #Makes the circle 2 times bigger. " ,
" set {_ellipse::*} to {_circle::*} scaled at player by 1 in direction vector 1, 1, 2 " ,
" #Makes the circle 2 times bigger in the z-direction but does not change the x- and y-coordinates. This creates an ellipse. " ,
" show happy villager at {_circle::*} " ,
" show happy villager at {_bigcircle::*} " ,
" show happy villager at {_ellipse::*} " } )
