c# - Game can't recognize enemy rectangle inside platform rectangle -


so tried make so; if enemies left side position more platforms right side, enemy turns other way, , vice versa. problem game can't recognize it. enemy jumps in air @ same time, made check x values. (right , left sides of rectangles)
here code:
these checks if it's inside of platform...

static class rectanglehelper {     public static bool isinsideof(this rectangle r1, rectangle r2)     {         return (r1.right >= r2.left &&             r1.left <= r2.right);     } } if (!chompball.rectangle.isinsideof(platform.rectangle)) {     if (chompball.movingright == true && chompball.canchangedirection == true)         chompball.movingright = false;     else if (chompball.movingright == false && chompball.canchangedirection == true)         chompball.movingright = true;     chompball.canchangedirection = false; }

i have tried change lot of things, removed ! see if worked, no. have no idea! funny thing works when it's touching ground(my other enemies), x coordinate matters, doesn't.
please help!
-edit:
split logic? mean doing this?: 

            if (!chompball.rectangle.isinsideof(platform.rectangle) && chompball.movingright == true)                 chompball.movingright = false;             else if (!chompball.rectangle.isinsideof(platform.rectangle) && chompball.movingright == false)                 chompball.movingright = true;

-edit 2: oh think know mean. make on rectanglehelper checks if it's right, , vice versa. still doesn't work, result same:

            if (chompball.rectangle.isrightof(platform.rectangle) && chompball.movingright == true)                 chompball.movingright = false;             else if (chompball.rectangle.isleftof(platform.rectangle) && chompball.movingright == false)                 chompball.movingright = true;

edit 3, enemy movements. can see, here "canchangedirection bool used. it's ment do; when enemy reached end of platforms, turns , can't turn again until 100ms. used doesn't stuck @ corner:

            if (movingright == true)             {                 position.x += 2;                 rotation += 0.05f;             }             else if (movingright == false)             {                 position.x -= 2;                 rotation -= 0.05f;             }              if (canchangedirection == false)             {                 timer += (float)gametime.elapsedgametime.totalmilliseconds;                 if (timer >= 100)                 {                     canchangedirection = true;                     timer = 0;                 }             }
