[1.10]Spawn a rotated cube particle

TominoCZ · August 14, 2016

Now it crashes in the cust particle class... It must be because of the parameters I passed it when I created a new instance of it..

this is the piece of code where I replace the particle:

queue.forEach(particle -> {
		queue.remove(particle);
		queue.add(new FBPParticleDigging(Minecraft.getMinecraft().theWorld, interpPosX, interpPosY, interpPosZ, motionX, motionY, motionZ, bs));
	});

I'm not sure why it's crashing, but it looks like it it because of the world instance.. or the BlockState..

WAIT I realized something.. I'm basically replacing every particle in the world

TominoCZ · August 14, 2016

Looks like it's because of the world instance. It says it's null. I hope I'm right..

now.. it crashes when the method onUpdate is called(because I check if the queue is not empty)...

					queue.add(new FBPParticleDigging(worldObj, interpPosX, interpPosY,

				}
			});

			ParticleManager particleManager = new ParticleManager(Minecraft.getMinecraft().theWorld, null);

			Class<?> c = particleManager.getClass();

			Field f;

			if (Main.isDev() == true)
				f = c.getDeclaredField("queueEntityFX");

Do a != null check aswell as a isEmpty check

TominoCZ · August 14, 2016

Sure. I was about to say this(below), when you answered..

Wait... If you think about it... you can't get the particles when you join the world, because there aren't any and also it scans for them once, once you've joined the world... so the Queue<Particle> is empty.. that means we'd have to somehow use TickHandler...

*Testing with using a classic for()*

EDIT: Well shit that doesn't work either.

TominoCZ · August 14, 2016

Alrigh. Did that. Trying it now.

TominoCZ · August 14, 2016

Well I can get the particles removed, I tested that, but I'd need to use ListIterator to add the particles.. but how do you make one out of a Queue? I'm so close to finally finish this!

TominoCZ · August 14, 2016

well then how am I going to replace ALL of them I want if I can't modify the queue in a loop?

TominoCZ · August 14, 2016

That clever AF

TominoCZ · August 14, 2016

no matter if it's in a loop or not, it says te exact same:

I don't know how you'd read private final fields without making a new instance of the previous particle class..

show me what it should look like.

No, you got the instance from the Iterator, you used it like 10 lines above.....

If you mean itr.next().getClass(), then no. I tried that.

I tried itr.next().getClass().newInstance() aswell.

Animefan8888 · August 14, 2016

No, you got the instance from the Iterator, you used it like 10 lines above.....

If you mean itr.next().getClass(), then no. I tried that.

I believe he wants you to create a field of itr.next() and use that instead of calling itr.next()

TominoCZ · August 14, 2016

already have that there

Class c = itr.next().getClass();

Draco18s · August 14, 2016

For fuck's sake.

Object o = it.next();

Stop calling

.getClass()

on everything.

Also, don't use Object. I put "

Object

" because I don't know the correct type (nor do I care). You're supposed to change it to match what you're doing.

TominoCZ · August 15, 2016

Alright, got it working, i'm now spawning the 3D particles, but the only problem is, that they go only one direction.. and spawning in the block actually under the block....

because when I call this:

new FBPParticleDigging(Minecraft.getMinecraft().theWorld, prevSourcePos.getX(), prevSourcePos.getY(), prevSourcePos.getZ(), 1, 1, 1, prevSourceState)

The parameters 1, 1, 1 are the X, Y and Z speed of the particle... so all the particles go sideways... pretty odd.. what it does.. I'll upload a video.. here's the link: -pointless-

EDIT: well that was pointless... fixed that....

TominoCZ · August 15, 2016

How often do I need to say this for you to listen to me?
You are still accessing prevSourcePos, etc. from
this
, which is completely meaningless here. You need to get them from the particle you remove from the queue.

just FYI:

public class FBPParticleEmitter extends ParticleEmitter 
{
Field SourcePos;
Field SourceState;

Queue<Particle> queue;

BlockPos prevSourcePos;
IBlockState prevSourceState;

public FBPParticleEmitter(Queue<Particle> q) {...
