How to make the player move to the left and right

[tlro]

I've absolutly no clue how to make this and i was wondering if I could get any help regarding this, im new to coding in java i have some experience in c++ other wise none.
I would be super glad if anyone would help me giving me hints but not completly giving the code, i want to find out by my self, i just need a starting point. I've read a little bit in the documentation and til now i have no idea where to start. I have the project ready. 

MC Version: 1.16.5
Forge Version: 36.2.39

Not entirely sure how 1.16 works (not supported anymore), but do you want to teleport or set velocity?

[tlro]

set velocity i belive

[Choccy Biscuit]

In 1.19, you can use lerpMotion, not sure what to do for 1.16

entity.lerpMotion(0.5F,0,0);

This will apply some velocity on the X axis, and can be changed easily (probably a bit high still).

Also, should be player and not entity.

I can change the project to 1.19 no problem with that if it makes it easier for you to explain

[Choccy Biscuit]

You should probably do that, since forums only support 1.19 and 1.20 currently.

why is it causing this crash? if its a private void it also gives me a crash.
