You would have a PlayerDamageEvent and check if the player was damaged by Fall damage, if so, cancel the event.
To prevent it from always happening, set up something like for when they jump, add them to a list, and remove them when they are damaged.

 

Should use a hashset instead of an arraylist, in the interest of performance

 

@Scimiguy ehst do you mean,tried so much so far and nothing workss,you maybe have an example of what you mean

 

@PeterXonwiiXx
Cancel the PlayerDamageEvent like Creeper suggested
