Drag the dots around to change the vector and the comparison point. See inside for some comments explaining dot products more Dot products are a cool math thingy that shows you how far away a vector is from the line that is perpendicular to another vector. The formula is this, where x1 is the x value of the first vector, and so on: x1*x2+y1*y2. It is very simple, but remember that the vectors have to be the same length(in other words, normalize them), and their origin point has to be the same. Dot products are very useful in things like physics and math. It can be used find the angle between two vectors, find out how similar two vectors are, if they are perpendicular or opposite to each other, and can also help a lot in making a physics engine, like the ones that come built-in when you use game engines like Godot or Unity. anyway they're cool bye
