[1.9] Particle Effect Stream | Damage Player Touching Side/Infront of Block

[DARKHAWX]

I have three questions for today:

[*]So currently have a block that will make a flame thrower like particle effect when activated with redstone. The problem is that I have put this code in renderUpdateTick and as such it does not activate nearly fast enough to make a steady steam of particles. Is there some way I can make it tick faster or should I be doing something else to get it to output a stream of particles?

[*]I want to make a block that only damages players if they are colliding with it from a certain side (whichever side the block is facing), is there an easy way to do this? Or should I simply just add a check in onEntityCollidedWithBlock()?

[*]My last question builds on from the last question. I want to make a block that damages the player if they are within three blocks in the direction the block was faced. I don't really know how I would go about this, any suggestions?

1) spawn more particles per tick with horizontal offsets from each other.

2) make the block less than a full block on that side.

3) step 1: get the facing direction step 2: multiply that direction by 3 step 3: make an AABB from the block to this new position

1) Works perfectly, thanks!

3) So this works mostly. The actual collision box of the block is now 2 blocks in the direction the block is facing (I'm meant to actually just collide with the block, but take damage when within 3 blocks of the block. I just kinda collide with the air), but the bounding box is shown to be 4 blocks in the direction (which is correct). Also the onEntityCollideWithBlock() method never gets called even when I'm touching the block

No no no, leave the collision box alone.  You want to getEntitiesWithinAABB(thing I said)

[DARKHAWX]

Oh, I didn't get that you meant getEntitiesWithinAABB, I kind a just read it as BB and thought I needed to change the bounding box.

 

So I'm meant to call worldIn.getEntitiesWithinAABB() and then damage all entities. But what method do I put that in?

 

It wouldn't be onEntityCollidedWithBlock, because that never gets called.

[Draco18s]

because that never gets called

 

It gets called if the player is inside the 1x1x1 standard volume of the block (your block would need a bounding box smaller than 1x1x1 for this to occur).

 

You would need to either:

a) schedule tick updates (say, every 10 ticks) and check in updateTick (and reschedule the update)

b) not schedule ticks and rely on random ticks (about once a minute)

c) use a tile entity and check every tick

 

A is the best solution.

Ah okay. Thanks!
