[Solved] How to get an entity to move to another entity's position w/out attempting to path find?

Hi all,

So currently, I am trying to make bats hunt silverfish. I cannot use the pathfinding function to do this as bat's movements are too sporadic. So I figured, what if the bats instead do a homing attack every 5 seconds?

So: Get the position of the silverfish and the position of the bat and define a vector with these two points. This vector specifies the difference in x, y, and z coords between the two mobs. To get x, y, and z velocities out of this vector, we need a time to divide each coord by a time. In my case, I want the move to be made in 1 second, so the magnitude of the velocity for each coord is just equal to the direction for each coord. Makes sense, right?

Look at the code: https://imgur.com/a/mcreator-code-7-22-2024-7Y9E0om
 

Can anyone tell me why this doesn't work? The bats seem to have more velocity than I expect, and often move away from the silverfish rather than toward. Sometimes they even disappear (I think they are moving underground). I have tried to define the vector going from silverfish to bat (the code as shown is going from bat to silverfish), and that has not worked either.

Thank you.

Edit: This has now been solved, the code works but it wasn't working either because of updating my MCreator version or my Minecraft and Forge version while updating the mod. The fix was to delete and recreate the procedure as written. Not really an elegant solution since I am not sure how it broke in the first place, but oh well.
