Click, walk to mousex/y

Hi, im currently making a game with basicly looks like a char in de middle of the screen and an landscape around it.
Now i want the player to click on anywhere on the background, and the char to walk towards that point.
It’s easy to make the char mc jump right to that point, but i want it to walk (play a walking mc) and move there in a certain speed. So it looks like the char is smoothly walking to that location.

I know about _xmouse/_ymouse etc. and about the walking movement and direction/sideview of the char that has to be shown for where it walks (click lower than current location will show the front of the char, left will show left side etc.). But can’t figure out how to move the char in certain speed between the current point and the new location.
