Unity Tutorial: Everything you need to know about Vectors
In this video I tried to cover as much useful information about Vectors in Unity as possible. We start by discussing what Vectors are, what useful properties they have then we go through most useful methods and at the end of the video I am giving 2 examples of solutions that require vectors.
This was until now the most challanging video to make. I hope you find it useful and enjoyable.
IMPORTANT NOTE:
Part about .Dot product contains an error - the .Dot returns value between -1 and 1 for NORMALIZED vectors. It can return other values than that if the we use vectors other than normalized.
