[Solved] How can I detect the walkable areas?

[Marsal]

I just restarted my old fun map project and I've noticed something wrong. There is a Jump ability but with it you can jump out of the playable map area. So for example you can jump into the water or into a decoration and you can only get out by jumping in the correct direction. How can I detect if an area is walk able? In the ability there is a variable that can config the maximum jump distance and I want to detect the farthest possible landing area.
I've only got one solution in my mind and I'm not even sure that it works and so I can't try it right now :/
So that is the idea:

• TempPoint = XYZ(loc 'n stuff)
• Create 1 Foot unit at XYZ
• TempPoint2 = Position of Foot unit
• If position of foot unit equal to TempPoint then allow jump there.

Will it work? If not, how can I make it?

• (Terrain pathing at (Center of (Playable map area)) of type Walkability is off) Equal to False

• ((Playable map area) contains (Center of (Playable map area))) Equal to True

EDIT: The first one doesn't seem to be working with trees at least.
