So, i have learned direction, unit and magnitude, i wanna ask some questions, whats the direction used for, Could You Give me some example?
For Raycasts and not only
One example i could give you is raycasting.
Say i want to make a gun, i click and it shoots. Raycast has a param that has direction. You get the vector3 from the mouse and extract the direction of it and insert it into the raycast.
This isnt limited only to raycast,you can also use it to point something, like let’s say a arrow that shows the player the nearest button to buy (in a tycoon)
