In this video we determine an equation for the shortest distance between some point C, and the line passing through points A and B.
The equation is: dst = abs((C.x-A.x) * (-B.y+A.y) + (C.y-A.y) * (B.x-A.x)) / sqrt((-B.y+A.y)^2 + (B.x-A.x)^2)
We also see how this equation can be modified to determine if two points lie on the same side of a line.
C# code for the equations can be found here: github.com/SebLague/Gamedev-Maths/blob/master/DistanceToLine.cs

Object pooling is an optimisation technique which is extremely helpful for boosting the performance of mobile games. The basic idea is to recycle a pool of objects, rather than continually instantiating and destroying new ones.
UPDATE:
At ~15:16 in the video, the lines copied should preferably be pasted BEFORE the call to OnObjectReuse(), so that when that method is called, the object will already have its correct position/rotation values. This could be important when resetting certain things, for example the velocity of a projectile based on its initial rotation.
