Spell4 > Custom Entangle - Problem with unit collision?

Ive been trying to make a varient of an entangling roots spell.
Similiar to Bone Prison - the Necromancer skill in d2.

It creates roots in an area, that trap units, the roots however can be smashed/broken.

It works fine except units can always just walk through the roots?
Ive set the collision size very high, is there something im missing?

thx

Make sure roots aren't flying unit... btw isn't it easier to make this spell based off that spell Archimonde has, summoning daemons and just make it summon roots??

Yup there not flying. :-)

Yea but I need to make the units in a circle?
With gaps inbetween

Any abilities, such as locust? What was the base unit?

You could make local pathing blockers for each root, if the root dies remove the specified blocker.

Most probally Pathing Blocker - Large

Ah think I found it>

Setting movement type - None
Makes them walk throughable

Interesting...
