Looking back at your code, it could be that because your car is moving in increments of .9 that it may never be meeting the distance requirment of .2 . If that is the case, it will keep flickering as it moves a little then points back at the destination. Try increasing
if d#<0.2
des=0
endif
to 1.8 (twice the distance the car would move in one iteration) and see if that helps. Then slowly reduce or increase the value until the car continues to respond 100% of the time.

Hello,
Well one thing I noticed in the first snippet
`points the charachter to it's destination and moves it
if des=1 then point object 4,desx#,0,desy#:move object 4,0.9
`if the mouse is clicked, then the destination is set
if mouseclick() = 1 then desx#=x#:desy#=y#:des=1
`if the charachter object reaches its destination, then it stops
dx#=desx#-object position x(4)
dz#=desy#-object position z(4)
d#=sqrt((dx#*dx#)+(dz#*dz#))
if d#<0.2
des=0
endif
this line:
point object 4,desx#,0,desy#
I don't know if the variable desy# is meant to be a z direction or a y direction but you have desy# in the z parameter for the POINT OBJECT command. If it is meant to be a z position, then just for clarity, maybe all occurences of the variable desy# should be changed to desz# - unless there is some reason to keep it named desy#. Because later, you are interchanging z# variables with it. Just seems a bit confusing...
Also, if the y value is set to 0, the object will be pointing down if it is above 0 and up if it is below 0 - probably not what you intend.
In general, when using the POINT OBJECT command, it's a good idea to know which plain you want the object that is pointing to be on. What I mean is, if you are driving a car and it is pointing somewhere in 3d space, the actual direction you point the car in will be an x and z direction. The y value of the car won't change unless you are going over a cliff, splashing into a lake, driving up a ramp, etc.
So, if you are on flat land, you want to maintain the cars y position and point to some world x and z so the command might look like:
rem assume the variable car is assigned 4 indicating it is
rem object number 4
rem now point the car towards a world position at desx and desz
cary#=OBJECT POSITION Y(car)
POINT OBJECT car desx#,cary#,desz#
Now if you actually have to point the car up or down, then the y value might be in terms of world coordinates as well instead of the cars own y position.
Here is an example of moving a cone through waypoints. Once it reaches one, it points in the direction of the next one. Maybe it will help.
rem cone through waypoints
