Movement System

Hello, I’m new here!
I found your website amazing, I read a lot of the tutorials and all about the isometry. I was trying to make a movement system in isometry. The movememnt would happen on mouse click only. Something like the Dofus movement (character is moved in the center of the tile).

Well the main problem is diagonal moving, I found a way doing it with easing, but I don’t like using it for moving, as it accelerates too much if it’s moved from 1 part of screen to another (if you lower the speed then the slowing down in the end is so sloooow).

I would be really glad for some pointers and short examples. I want to learn what I’m doing so I don’t want the soulution.

Thanks in advance,
