Map size and lag issue

Well...

1) What map size means. I mean when I have map size 64 x 64, what it means in w3 length units (ranges etc) 64 x 64 = 64000 x 64000 ?? (hope you understand what I mean)

2) I wonder if that would lag if I had like 10000 (w00t) units without model. I know that models lag mostly but units take place in memory too. So?

I think each 1x1 cell is 128x128 in size. Meaning if you get a units attack range to 128 it will be able to only attack from the distance of one cell.

Well... I have another question that gives me trouble... why if I change unit model to "none.mdl", unit is no longer selectable?

I'm not really sure about this one. I think that when a unit doesn't have a model it's like a error and the unit cant be made. If your looking for a blank model thats selectable try either using the ability model "Abilities\Spells\Human\Invisibility\InvisibilityTarget.mdl" or use the dummy.mdl from Vex's ability map.

Because you select a unit by clicking on its model. With no model, you can't click on it (you can stil drag select it I think).

yah what he said ^^

It can't be drag selected, thats funny. I think it has got something with Min and MaxExtents in model. Oh and Zandose, congratulations, your first rep

I believe that is incorrect, i have frequently used " " in the model path field and never had an issue.

In the editor, there are 3 sizes of grid:
Small - (32 Value)
Medium - 4 smalls in a medium (128 Value)
Large - 4 medium, or 16 small in one large (512 value)

If you can't drag-select the model, you did something wrong (or you're talking about a unit with 'aloc' ability in-game, which is supposed to be unselectable). A unit with an invalid model should work in every way like a unit with a normal model, except you can't click-select it.

Inside a model file, each group of triangles (what models are built from) is marked as selectable or nunselectable. You click-select a unit by clicking on a part of it's model marked as selectable.

If you want to be able to click-select a unit without it having a model, it's possible to just make invisible triangles and mark them as selectable.

Yes, and the pathing maps are accurate to 64 units. A single pixel in a pathing map is 32 units, but the editor only lets you place buildings on a grid that is 64 units wide so pathing maps should have everything done in a grid of 2 pixels.
The terrain itself is done in a medium grid (128 units), and for comparison that is the width of the default scout tower.

Thats strange... I didn't added Locust, of course, but can't even drag select... maybe it has something that it has Worker classification?

Click on the Idle Worker icon in the left corner - Does it then select the modelless unit?

Yes... it selects it, I can also when I select that unit and griffin I can attack the unit. Can it be something that I have like >2000 of these units?

EDIT: Found something in old threads:
