how to cast and spell at the same time？

I want to write a script, but I found a problem, casting a spell and can not move at the same time, how to achieve both at the same time

 

Well, you can't cast spells and move at the same time in WoW, how would HB make that possible?

 

I think you mean spells that you can cast and move with but HB doesn't move when casting?

 

yes,for example: i am a warlock,cast Hellfire and move at the same time，this is no contradiction
