How to implement a 2D machine?

Question

C++ / C#

Hello! How can I implement car control (top view) in C++ using SDL or SFML (because they are similar)?
I need to make the machine move in the direction with the UP key, and the LEFT and RIGHT keys change the direction, but how can I implement this programmatically?

Answer 1

Use movement direction vector:
UP - moves the "car" a certain distance along the vector.
LEFT/RIGHT - rotate the direction vector by a certain angle.
The specific implementation is at your own discretion (working with a vector in an elementary form is easily implemented even with standard C ++ tools, using SDL to implement control is easy to find on the Internet).
