hey layzer
well first make the object(s) that u want to rotate and make an origion brush where u want ur object to rotate around. the origion brush will act like the axis of ur object but it will be invisable in the game. now select ur object(s) AND the origion brush and make it a func_rotating entitie. if u want it to rotate around the z axis ur done if u want it to rotate around the y or x axis u need to check off the y-axis or x-axis spanflag. i know u dont know the basics of mapping, and i know u shouldnt start mapping but so i dont confuse u layzer the x axis goes up and down so ur object(s) will be rotating like a rotating door. x and y axis are side ways.
sorry i havent been on xfire to help u but my cpu crashed and my xfire wont run.
