I want to learn how to make enemy bullets aim like in low-res Galaxy but I'm a little confused

The idea is to calculate the "normal":
At first you just calculate the the distances for both X and Y between the two objects. This gives you already the vector of the direction, but it's too long. You need to calculate the length of it, and then divide both X and Y by the length. This is the "normal" vector, which can be used to move a sprite step by step.
