I have a map in a game. I need to make a list with all visible objects for a
player
So, any building and any unit offer a range of visibility over the map.
Now VB question:
How can I store the references of that visible objects in a collection, to
make sure I added one object only once...?
Moreover ..how to determine if a certain object belong to the visible
list...
I could have a GraphicsPath from all regions visible to the the Player and
iterate through all other players's objects, and check out if it is inside
the visible GraphicsPath, but I noticed that GraphicsPath.Is Visible is very
slow even with 2 circles added to the path...
Any thoughts?

I am sorry I am not good at English.
But I can still guess what you want to express.
I can't express my thoughts clearly in English,so I try to
use some Example.
You can make a table of that map your have infered.
This table have a X,Y location.An array can eailsy store
it, A(640,480) restores an map's information which size
is 640*480.If you have a unit Called marine ,it's vision
sight is 10,and this marine's position is (400,300).Then
for i=400-10 to 400+10
for j=300-10 to 300+10
If a(i,j)=0 then
A(i,j)=1
End if
next
next
If another Marine come to nearbY, you can do same
operation too.
Wish this can help you .
Best Regards Menu Chen
And I only have to ckeck for each other object if it's location is 0 or 1 in
that array... good ideea
This way, no need for GraphPath
Say around, I may have some other q for you and seems you are up to date on
this issues :)
Thanks

You can add them to a 'Hashtable'.

Oh,I see.
I know now my solution is slow.
Have you ever played a game by Blizzard called
starcraft.Do you mean to make the effects like what it
have done? I think ther original map is all visible for
player.And when you place the black fog on it ,it will
seem as if there is a vision for each unit.I mean there
were be two layers on your program.One is covered by
another. So ,you didn't have to check the array every
time. Just place the fog one time and give the attention
to each change. for example ,if a marine move , his vision
will change withe him .And this time ,what you have to do
all is change the array and modify the the upper layer.You
don't have to redraw all the map now .In ohter words ,the
fog Layer can be seen as a picture paint on black.And when
you want to show the vision of a unit,just make modify the
picture's by pixels.
Say Sorry for my poor English again.
Wish this help.

In fact, My goal for this question was how to filter objects on the map from
