Hello fantastic people! If you're into game development, understanding vectors is a must. This video explains the concept of vectors, focusing on how to use vectors in Unity for both 2D and 3D applications.
We cover important vector properties and core vector methods, making it a perfect unity tutorial for any gamedev looking to enhance their projects with unity vector2 and unity vector3 functionality.
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.
