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

current code it crashes.

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

set velocity i belive

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

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.

never mind, the code works!
