Description
I found a few formatting errors in the PVector tutorial (https://processing.org/tutorials/pvector):
“SPEED: xspeed and yspeed In a more advanced sketch, we could imagine this ball and world having many more properties:”
Should be something like (with a period and line-break):
SPEED: xspeed and yspeed.
In a more advanced sketch, we could imagine this ball and world having many more properties:
Moving onto multiplication, we have to think a little bit differently. When we talk about multiplying a vector what we usually mean is scaling a vector. Maybe we want a vector to be twice its size or one-third its size, etc. In this case, we are saying “Multiply a vector by 2” or “Multiply a vector by 1/3&rquo;. Note we are multiplying a vector by a scalar, a single number, not another vector.
&rquo; should be: ”
The associative rule: (nm)v = n(mv) The distributive rule, 2 scalars, 1 vector: (n + m)v = nv + mv The distributive rule, 2 vectors, 1 scalar : (u +v)n = nu + nv
Line-breaks are missing.
In the (http://processing.org/reference/PVector.html)[**PVector**] class, we therefore write our normalization function as follows:
Link is broken.
