setMoveTo function always moves entity at same speed

[razakma15]

The function getMoveHelper().setMoveTo always moves my flying entity at the same speed regardless of the speedIn value I use.

 

The version is 1.12.2 but i'll be porting it to 1.14 so i'll need this fix anyway.

 

If the function doesnt apply for flying entities can anyone recommend me a similar function.

 

- Thanks in advance.
