[1.9.4] onEntityCollidedWithBlock not working as planned.

[oneofthem999]

So I was trying to test out the idea of using blocks that checks whether or not a custom potion effect is active on the player when the player steps on the block.  The KillBlock in this scenario should kill the player when the player steps on the block, if the player does not have a custom potion effect.  The NeutralizationBlock should remove all potion effects the player has when stepped on.  The Aura Potion is a generic potion that just add a speed 2 potion effect.  Really, its just filler, since the idea was to learn how to create a custom potion.  I wanted to be able to access the potion in one of the creative mode tabs, so I created a food item that grants the potion effect.

 

However, the KillBlock and NeutralizationBlock does not work as expected.  When stepped on, no effect takes place.  A session of debugging determined that the onEntityCollidedWithBlock method didn't trigger at all, leading me to think that the method does not do what I originally thought it did.

 

How do I improve the code such that the KillBlock and NeutralizationBlock will trigger when stepped on?

 

Here's the NeutralizationBlock code:

And the KillBlock code:

The AuraPotionEventHook code:

The AuraPotion code:

And finally, the Main code:

Thank you in advance.

Entities can only collide with your block if it has a collision bounding box smaller than a full cube.

Block#onEntityCollidedWithBlock

will never be called if your block has the default bounding box.

 

Either give your blocks a bounding box with a maximum y coordinate slightly less than 1 (look at

BlockSoulSand

for an example) or override

Block#onEntityWalking

instead. Note that flying or sneaking players don't trigger walking.

onEntityWalking also is not guaranteed to trigger for every block the player steps on.

The blocks work as expected now.  Thank you very much everyone!
