Scalars and vectors – a section review

In this section, we discussed the important differences between the values of vectors and scalars, their definitions in the case of real-world mathematical quantities and in the realm of Unreal Engine 4. In addition, we looked at some in-engine examples of how to use scalars and vectors in materials and blueprints. We also looked at how to incorporate scalars and vectors so that it can dynamically change the color of a material. With a base understanding of scalars and vectors in our pockets, we can now discuss Newton's laws of physics.
