[General] Pathability for Dummies [Jass]

[maxodors]

I am looking for an efficient way to detect if there are decorations in the area or unit type structure. Ideally, I am looking for a system. I want my certain projectiles to go through high ground (level 1) and low ground (level 1), but not go through trees, towers and decorations (walls). I attached a screen to show what I mean by high ground and low ground. Note, I don't want them to go through above level 1.

There's a condition to check the Cliff Level at a Point and you can use Pick Every Destructable to find nearby Trees/Walls (if the Walls are destructables). For Towers, you can use Pick Every Unit to find nearby units.

And as far as I know there is no high/low ground (level 1), I'm pretty sure the cliff levels start at 0 and works their way up to 14. You'll want to figure out what you set your maps starting cliff level to so you can figure out the -1/+1 values of it. You should really only need to know the level of the "high ground" since your Condition will probably be something like "If Cliff Level at missile point > high ground level then destroy missile".
