Well,I don't know how exactly to explain this , but I saw it in entidad and tough it would be possible in RF too.In the games made in RF when you start walking the player starts walking immediately,but in entidad when you start walinkg the waling speed starts to encrease till the player reaches his full walking speed and when you stop walking the walinkg speed starts to decrease till the player stops.Is this possible to make in RF or not if you haven't understood me I can upload a video of that .
