Im trying to rotate an object X degrees, nut i want that when the rotation happends it isent all suden, i want that you can see the object spining all the way to the X degree. (im try ing to me more clear) (I'm pretty new at this so please be patient with me)

            switch (enemywalk)
            {
        case 1:
            colx = enemy.y;
            enemy.y -= 115;
            if ( enemy.hitTestObject (pared1) || enemy.hitTestObject (pared2) )
            {
             enemy.y = colx;
            }
            enemy.rotation = enemyrotate; //random generated number
            break;
            }
