Changing Unit's movement Type by trigger(without replacing/not fly type)

[Nike2000]

Hey, I've been trying to change the Unit's movement type into Amphibious, but i can't use replacement because it gives me some errors. If there's any ablility/item that can help please tell me, I really need it. Thanks.
Any trigger/custom value/jass will be much appreciated.

I guess you would want to change the unit's movement type to "fly" or, what is it called "hover"? I am very sure this can't be done with normal triggers. You will probably have to ask in the JASS forum

Not fly, amphibious
