How would I go about creating unit sprites for multiple players that can walk through other units? Can these be detected by location? Thanks in advance

Check the flag "Active / Disabled (?)" in the sprite properties (assuming you use SCMDraft 2; also, make sure you click the sprite unit in the properties list, as it isn't automatically selected when the properties window comes up). Then enable the doodad state of the unit with triggers. This removes the collision but allows the unit to move around as normal. I forget if it sets the unit to an illegal frame, but it probably does, so after you enable it, order it to move somewhere (also make sure the player can't see this process happen, or else the player may crash from the game).

Here's the steps in a more organized fashion:

1) Place a Unit Sprite in an area players won't see it
2) Open the Sprite Properties (right-click -> Properties) and select the Unit Sprite
3) Check the "Active / Disabled (?)" flag
4) Make a trigger enabling doodad state for the Unit Sprite
5) Also have the trigger order the Unit Sprite to move

Keep in mind this does not work for some units. Unit Sprites can be detected using locations; they're just like regular units as far as triggers are concerned.

How do you make an area not visible to players who own units there?

Edit: I followed your instructions exactly and it still will not walk through units.

Yeah, I'm pretty sure that a unit without bounding boxes cannot walk through other units, but other units can walk through/over it (if that makes sense). This makes it of rather limited utility.

Lanthanide is correct; the unit can be walked through, but it itself cannot walk through things that still have collision.

Make the unit owned by a computer and don't give it to a player until the process is complete.
