Check Terrain at Position of Unit

[mikey4555]

Is it at all possible to check the type of terrain at a position of a unit?

I've been trying to create a projectile collision system for quite some time now, and specific to my game, I would need a 'check terrain at position of *' condition.

Is this at all possible in Star Craft 2? If so, please inform me.

If this isn't possible, could someone please give me insight to what I could use as an alternative?

It is impossible outside of creep/not creep. This is because terrain is made by mixing multiple textures together so there is no clear cut texture type.

You could make regions for different terain types and test if the unit is in them.

Yeah, I was debating to use regions - but it would be very inefficient and tedious for my map.

Although, I do have another question, come to think of it. Would it be possible to check if a unit is in range of a doodad, actor or model?

Oh man.. I just found it out. For anyone who wants to know how to check custom pathing, look below. It uses the built in 'pathing' layer, whereas in my system you place "no pathing" in the areas you want your projectiles to stop.
The condition is labelled as "Points Connected By Pathing"

The condition includes:

I do not think it is a very fast opperation. Be careful you do not cause performance problems.

There is a "Point is passable" function, that works only for one point, which would be the right choice for your condition, and much more efficient.
