Mounting

A) It is wrong idea

B) It is better, but not such good idea. Even if you can check mount is inside obstacle, what you suppose to do?

you stop him from going inside it in the first place. you also set the type on the guy on the mount ( or the mount ) to Walkable.

Interesting...is there some trigger/jass function to add/remove Walkable to unit?

Do you mean Turn Unit Pathing On/Off

huh? Where is Turn Unit Pathing On/Off? I know only Collision

The Turn Pathing On/Of is the same thing as the collision

( srry im thinking JASS names )

If is that same thing, then it is useless, because turn collisions off make unit ignore obstacles but it is still treated as obstacle and that is my problem!!!

then make one of the two units ( the mount ) a locust. it is not considered for pathing purposes

dont make me mad...

? locusts I KNOW are not considered for pathing, otherwise dummies would interfere with Gameplay.

ofc, but I need mount to be controled and targeted and this is imposible for loctus. So, problem lasts...

you control the rider, the mounts thru triggers

why dont you make the rider a locust, so you can control the mount, so the rider can attack while the mount is moveing and all you have to add is an trigger that makes the rider attack an target if the mount is ordered to attack one

Im sure youd rather see the rider's face

Just change the mounts portrait model to its face.
