I have a hashMap that uses BlockPos as a key.

 

CODE

 

 

public static HashMap<BlockPos, Boolean> currentRespawnLocs = new HashMap<BlockPos, Boolean(1000);

 

 

 

However, I would like to use the "get(object) function to obtain the Boolean that is inside, within my event handler...

 

The only way I know how to obtain a BlockPos is like so..

 

 

new BlockPos(0,0,0);

or, BlockPos currentPos = event.pos;//inside my event handler

 

 

 

When using new, BlockPos is now consider an entirely new object and inside my hashMap, it doesn't exist.

 

Example:

 

 

currentRespawnLocs.put(new BlockPos(0,0,0), true);

currentRespawnLocs.get(new BlockPos(0,0,0));//this returns null;

 

 

 

Does anyone know any work arounds or even a better way to implement this?

Thanks:)

You can create your own class that wraps around BlockPos. Override the equals and hashCode methods to return the proper values when the x, y, and z are the same.

Have you tried:

 

BlockPos pos = new BlockPos(0, 0, 0);

currentRespawnLocs.put(pos, true);

currentRespawnLocs.get(pos);

Long story short: BlockPos does not override Equals and HashCode, so it isn't (usefully) hashtableable.

 

Have you tried:

 

BlockPos pos = new BlockPos(0, 0, 0);

currentRespawnLocs.put(pos, true);

currentRespawnLocs.get(pos);

 

While this will return a value, this is not useful, because this fails:

 

BlockPos pos = new BlockPos(0, 0, 0);
currentRespawnLocs.put(pos, true);
pos = new BlockPos(0, 0, 0);
currentRespawnLocs.get(pos);

Have you tried:

 

BlockPos pos = new BlockPos(0, 0, 0);

currentRespawnLocs.put(pos, true);

currentRespawnLocs.get(pos);

 

This does work.  However, I acquire the blockPos position in the event.  In my main code, I declare the locations that I want to have as either a true or false output.

 

 

 

//similar to this

//In my initialization method

currentRespawnLocs.put(new BlockPos(0,0,0), true);

 

//In my event handler

BlockPos currentLoc = event.pos;//the BlockPos x, y, and z are all equal to 0

currentRespawnLocs.get(currentLoc);//returns a null.

 

I may use an array of ints in the first method instead of blockPos.  Should work.

 

 

Override the equals and hashCode methods to return the proper values when the x, y, and z are the same.

 

What do you mean by returning proper values?

 

I will have different x y and z values.  Hundreds actually.

Proper values as-in: hashCode returns the same int if BlockPos's x, y and z are the same and equals returns true if the x, y and z are all equal.

 

So basically, he wants you to create a hash-able wrapper around your BlockPos that you can then store on that hash map of yours.

This is not true. Check Vec3i.

 

Sorry, I was basing off the fact that it didn't work (implying that BlockPos was not overriding those functions).
