Hi. I have watched some tutorials, and I have some questions related to vectors.

- How is a vector defined in UE4. A vector variable is just x,y and z coordinates or it also contains direction and length.
- In this video:

By multiplying a vector by 2, you get a higher velocity. In UE4, does multiplying a vector increase its length or velocity ?

- Why in this video, the dev divides the vector length by 50 ? What vector length actually means in ue4 ? I imagine a vector as an arrow in the direction deducted from coordinates. By dividing the vector, the pillar spawns further or nearer to the vector point ? (the movable one)

By multiplying the vector by 100, it increases its length so the projectile is spawned further (the end of the arrow/vector is further, because it’s longer) ?
