I got the hm 06 rock smash after win gym badge of mauville but i use it to break any how do make it?

It sounds like you're trying to use the HM06 Rock Smash to break rocks, but you're having trouble. Here's how you can use it:

* Make sure you have the HM06 equipped: Go to your Bag and select "HMs". You should see Rock Smash there. Select it and choose "Equip".

* Find a rock you can break: Rock Smash is used to break specific rocks that are gray in color. Look for these around the map, especially near paths or areas you need to explore.

* Use Rock Smash in battle: Once you find a rock you want to break, approach it and interact with it. Your Pokémon will automatically enter battle against the rock. Use Rock Smash as your move to shatter it.

Here are some common reasons why Rock Smash might not be working:

* You're not using it on the correct rock: Make sure you're trying to break a gray rock. Other rocks might be unbreakable.

* You haven't learned Rock Smash yet: You can only learn HMs after you earn the corresponding Gym Badge. If you haven't earned the badge yet, you won't be able to use the HM.

* You haven't equipped Rock Smash: Make sure you've equipped Rock Smash from your Bag.

Let me know if you're still having trouble, and I'll try to help further!
