[1.16.4] Make LivingEntity move in the Direction it's facing

[FenrisFox86]

So I'm creating a mod that adds a bunch of new tool- and weapon types. One of them should make the player dash forward when they charged it.

I was able to use some of the bow's code to make the charging work but neither do I know how to get the Horizontal Direction that the player's facing as a 3dVector, nor do I know how to accelerate a LivingEntity in a given direction. 

So how can I make a player dash in the horizontal direction they're facing?

you can get it via Entity#getViewVector, use as the float parameter 1 else the value will be lerp with the current view vector, the last view vector and the parameter you given

not sure but try to scale the vector

Solved: 

I made the stupid mistake to handle movement server-side first. That's why the movement never worked. The method Entity#getLookVector returns the correct vector and I simply had to pass it to the Entity#setMotion method.

you can handle it on server-side just set after handling (Server)PlayerEntity#hurtMarked to true this will update the player and also the movement

Just something important for people trying to do a similar thing: normalize the vector and then multiply it by a factor you need. Otherways the vector's going to be as long as the player's distance to the block they're facing so the dash won't have a consistent length. 

Vector3d vector = player.getLookVec().normalize().mul(factor, factor, factor);
player.setMotion(vector);
