Help with explosive pickaxe

Hello i have been working on a plugin for a couple of days and ive got this far without a problem, but of course i stumbled upon one today. The problem is that players are bouncing away when they mine a block since the pickaxe, causes a explosion. Here is my code, if anyone could tell me the code to stop the bouncing away. Since i have no clue how or what way to stop it, also if you could tell me where to put it that would be great. Thanks. Here is the code!
This is the explosive pickaxe class:

This is the Commands class:

This is the EventListener Class:

Thanks and have a good day!

 

you could try canceling the PlayerVelocityEvent, if that's triggered on explosions. Also, just a tiny thing I noticed: your getInstance() really isn't useful for getting your main class instance because it isn't static. Just a tiny thing.

You can't use a 'this' reference in a static context

Code:java

createExplosion (double x, double y, double z, float power)

Try to set the power to 0

 

Unica That doesn't mean that you can't use a variable xD
What's the point of a getInstance() that you can't use without instantiating the class into another object ?

 

Abs0rbed

You're right about that. I would rather just use an constructor. But I just wanted to point out that he cannot make it static

 

Unica Just out of curiosity, if the power is 0, won't it nullify damage to blocks? Kinda skimmed the pastebin, can't remember if andrewginn wanted blocks broken or not.
Edit: Saw that he's breaking the blocks with his code, not the explosion. Setting it to 0 should work fine

 

I want the explosions but not to deal player damage or pushing them back Abs0rbed
Also i have got the java for dummies book and my friend helped me with most of this coding.
After reading the book will i become experienced in java or not?
Also can you tell me how you learnt java since i need to learn it quick and how long did it take you to learn? Unica

 

andrewginn I'm self taught, using some pretty gigantic books. I used Java: A Beginner's Guide by Herbert Schildt, along with reading oracle docs, then I moved up through higher level stuff. Just out of curiosity, why do you need to learn so quickly?

 

andrewginn

Setting the power to 0 will remove the damage (right?). I assume without the damage there is also no knockback.
Concerning your question, I used the internet. But I started off with alot of bad practise, therefor I think books are probably better.
thenewboston also makes pretty good tutorials for alot of programming languages. And learning takes time, but if you do your best, it will be worth it

 

andrewginn Unica thenewboston's tutorials are really good, but I think books are better (mainly because I can read them in class when I'm supposed to be paying attention xD) It should remove the damage, as power 4 is tnt

Regarding your main class

• You should only register the command explosivepickaxe, and set ep as it's alias (this also means that you only need to check cmd.getName().equals("explosivepickaxe")).
• Instead of using \ or / in file paths, use File.separator. Even better would be using the second constructor of File, File(directory, filename).
• Don't use the Minecraft Logger, use the Logger object you get by extending JavaPlugin.
• Instead of using a List<ItemStack> to check if an ItemStack is a pickaxe, use an EnumSet<Material>:
  • Sets are better for contains() operations since they don't require you to check every element in the List (and yes, that's what it does ).
  • EnumSets are optimised for enums.

Regarding EventListener

• Be aware of null ItemStacks (afaik player.getItemInHand() could return null.
• Check if the ItemMeta has lore before getting the first element of the lore.
