Well, you have what appears to be the corrected code in the act method. But, you also have something twice in the hit method. That would cause problems.
The other one is if a bullet hits me should i make a seperate method for it?
You should not need a separate method for the bullet; but, you should not have Heartless collision checking twice in you class (once in the act method and again in the hit method). I suggest removing the Heartless check in the act method and replacing the check in the hit method with the code removed.
it works but when my actor touches the enemy it's been removed even tho the hp isn't empty yet
It looks like you have code in your Heartless class where if it is touching the player when it fires a Heartlessblast, annihilate causes game over.
can i also have the code for the random jumping i don't quite get it
Where is the class code? Show what you have attempted? Explain what it is doing as opposed to what it should be doing. To start off, you will need to assign some values (other than zero) to the acceleration and JumpChance fields.

}but it's not jumping
Line 72 restricts jumping until the 'OnGround' field is set to 'true'. I do not see anywhere where that could possibly happen in this class as it is. That, and you are over-complicating things by adding redundancies ('CanJump', 'OnGround', 'isOnGround()'). You really only need one of them. 'OnGround' is synonymous with 'CanJump'; and 'isOnGround()' would return a more current state than 'OnGround' might contain.
I tried it like this now it jumps but it only jumps little by little until it goes to the top it doesn't jump like how my main character jumps and it doesn't fall as well
