Charge Spell Movement

[lnfernal]

I made a charge spell and I got problem with the periodic movement trigger which I used. When the caster targets a unit who is behind a doodad or a wall, the caster gets stuck on the wall. I know why this happens but not how to solve it. What I want is that the caster will acts like he got an attack orde so he'll turn around the doodad instead of keep walking into the doodad, but at the same time I want to use the periodic thing so he'll walk faster.
Could u guys find a solution?
(I don't want to use the collision thing)

Well here's the trigger Periodic Movement trigger.
Don't think u need the casting trigger, but if u need it I'll post it too.
Thanks in advance
