[1.9] Modify Vanilla Block Behaviour

[DARKHAWX]

So I want to make small modifications base vanilla block behaviour, specifically make rose bushes prick (damage) the player when walking through them. I'm not sure how I could do this, and I don't want to go around experimenting with stuff as that will probably break everything.

 

How would I go about doing this? For my specific case is their an easy and simple way of adding functionality to blocks/items?

How you add functionality depends on the functionality you're adding.

 

In this case, there's no event for block collisions so you'll need to subscribe to either

PlayerTickEvent

(fired only for players, make sure you check the event's

Phase

before running your code) or

LivingUpdateEvent

(fired for all living entities). In your event handler, iterate through all blocks inside the entity's bounding box (see

Entity#doBlockCollisions

) and check if each one is a rose bush before damaging the entity.

Ty so much. I ended up getting it working, although the check to see if its a rose and not another type of flower is a bit messy, but it works!

You might also look at how cactus does its damage. There might be something to learn there.

Cactus uses the onCollide method, which not all blocks override.
