How do I make the player move like in an RPG.

I am creating an RPG game in which the character can move in a 2D space. To do so, I put an "8-direction", would you have a better solution? With this behavior, the player undergoes unwanted acceleration and deceleration. Something simple if possible.

Just use super huge values, like 10000, for acceleration and deceleration and it will fix this.

It works perfectly, thank you very much !
