Sliding Something Along a Line in Godot (Dot Product Math)
49Today we learn how to use the dot product to clamp something along a line :)
Maxdot product explanation:
The maxdot variable is to find the end of the line, essentially the value we want to clamp to, if you try the code out locally, and change what values you use for maxdot, smaller values will have the follower move a small distance, while larger values have the follower moving wayyyy past the end of the line
