Player Interact with a Block Help

Hey guys I am making a Parkour coins system for my network and I want to know how to Give coins on completing parkour when player interact with a Block which is NetherBrick in my case! I put a code but it came up with errors!

Here's a empty Event, tell me what to add!

Code:

   @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event){
        Player player = event.getPlayer();
        giveCoins(player, 100) //My coin system give coin system!
}

Thanks in Advance!

@AdityaTD don't bump in periods less than 24 hours.
To do it, get block under player, get its type and if it is nether brick do The coin system stuff

 

Solved?

If so let's change the title

Second, if you edited the code, just post it so we can help!

Third, did you:
1. Register the handler
2. Use event's getBlockClicked() method, and check the material.

Good luck!

 

@AdityaTD Get the player who clicked it (event#getWhoClicked()), check if it was a right click, add the coins.
