I got the basic, by editing the mover class  (but i use
movingThing :D )

public void pmove(double distance)
    {
        double angle = Math.toRadians( getRotation() );
        int x = (int) Math.round(getX() + Math.cos(angle) * distance);
        int y = (int) Math.round(getY() + Math.sin(angle) * distance);

        List p = getWorld().getObjectsAt(x, y, Wall.class);
        Iterator i = p.iterator();
        while(i.hasNext())
            {
            while(i.hasNext())   <<< i want to loop by decreasing the
speed, but no work :(
            {
                  angle = Math.toRadians( getRotation() );
                  x = (int) Math.round(getX() + Math.cos(angle) *
(distance - w) );
                  y = (int) Math.round(getY() + Math.sin(angle) *
(distance - w) );
                  w++;
                  break;
            }
            }

            if(!i.hasNext())
            {
                w=0;
                setLocation(x, y);
            }

    }

That code will check if there is a wall.class at the target position,
if there, i want to decrease the speed, so it will be smoother but it
did not work.

I want to create more smooth movement, like if the object is at world
edge.
help me pleasee ^_^

Creating one while loop inside another isn't the way to go about
decreasing the speed smoothly - if it did decrease it noticeably at
all, then all it'd do was make the game run more jerkily!

Personally, I wouldn't edit the mover class at all to do this, I'd
create a subclass and put all your code there. If I've understood you
correctly, then you just want something to slow down before it hits
something else? Just because it's christmas (almost), here's a demo
with source. Have a look at it and you should be able to work out what
it's doing :)

nooo, not like that
like...

you create an object, maybe.. it called car, in the subclass of mover

you move it, to the world edge, the car stoped
and then you turn slowly, and the car move along the edge

thats what i want to do, but not at the world edge, but at wall.

hmm... aha, think like the world edge is an object :)

Sorry, I'm still not entirely sure what you mean - do you want the car
to turn gradually when it comes close to a wall then head off in
another direction?

no problem !!!  :-)

hmm, nope, i want the car stop ! :D, stop like at the world edge.

stop, for i while, i handle if car, get collision with other object,
turn(-180); so its move back.
but i want to.. like at the world edge ^_^

i think i will put all the source
...
i think again i will upload it to the gallery ^_^"

make it check if its intersecting the wall object and if it is then turn it

not turning, stop
btw, i already uploaded the scenario : ) take a look please : )
http://www.greenfootgallery.org/scenarios/522

In what way does that scenario not do what you want it to do? The
apple hits the wall, and stops...

yes, but if you slowly turn (press up too), then the apple just 'jumping'
compare it with if the apple go to world edge
if you go to world edge, the apple stop. but if you turn slowly, the apple
move slowly.

I see what you mean now - I think. Have a look at http://greenfootgallery.org/scenarios/524

thanks !
that is what i looking for :-)

thanks !
