How would you make a unit walk the bottom of the ocean.

Basically, I want a unit to traverse water, but I don't want it to float, I want it to ignore the water and walk along the terrain beneath the water furface "plane", on the ground.

I recently realized, when triggering a missile, that movement type "none" caused the missile to move on the bottom of the water. Using fly, it moved above the water.
I don't know if that helps you, because movement type "none" does not allow movement (I used SetUnitX/Y).
If you would somehow trigger movement, that would be an option. Apart from that maybe using flying height and GetLocationZ could work too.

SetUnitFlyHeight to a negative number?

 

[The_Silent]

The idea is that it walks along the ground, I assume negative fly height will lock it to a static height beneath the water plane instead of letting it follow the z coordinate of the ground beneath.

GetLocationZ does return the max(terrainheight, waterheight), so you cannot get the height of the water ground.

Using "none" as movement type works apparently, but it ignores all kind of pathing.
