hi i'm making rts style game , having problem getting selecting , highlighting vehicles. here errors im having. help appreciated.

assets/scripts/unit2.cs(19,51): error cs0120: object reference required access non-static fellow member `cameraoperator.invertmousey(float)'

here script.

you have not operator on vector. guessing want on entire evaluation, move ! outside of parentheses.

if(!(movetodest == vector3.zero) && !(transform.position == movetodest)) {

or alter operator utilize != operator:

if((movetodest != vector3.zero) && (transform.position != movetodest)) {
