[1.10]Spawn a rotated cube particle

TominoCZ · August 11, 2016

this is a mod I made for forge MC 1.7.10(I rendered the cube faces using vertexes with UV): http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/2724621-1-7-10-fancy-block-particles-3d-break-particles

now I need to draw the same cube, but randomly rotated when it spawns.

since it's a coremod, I need to change the code of the file ParticleDigging.class, but I don't know how to set a random rotation to the cube in 1.10...(doesn't need to keep rotating while falling).

Every vertex has it's own position. I need to edit those positions so the the faces, the whole cube is rotated.

Every cube face is 4 vertexes - points that make the face. there's 24 points/vertexes in total(6 faces * 4 points/vertexes each) that I need to rotate(change their position).

in this method:

public void renderParticle(VertexBuffer worldRendererIn, Entity entityIn, float partialTicks, float rotationX, float rotationZ, float rotationYZ, float rotationXY, float rotationXZ)
    {
        float f = ((float)this.particleTextureIndexX + this.particleTextureJitterX / 4.0F) / 16.0F;
        float f1 = f + 0.015609375F;
        float f2 = ((float)this.particleTextureIndexY + this.particleTextureJitterY / 4.0F) / 16.0F;
        float f3 = f2 + 0.015609375F;
        float f4 = 0.1F * this.particleScale;

        if (this.particleTexture != null)
        {
            f = this.particleTexture.getInterpolatedU((double)(this.particleTextureJitterX / 4.0F * 16.0F));
            f1 = this.particleTexture.getInterpolatedU((double)((this.particleTextureJitterX + 1.0F) / 4.0F * 16.0F));
            f2 = this.particleTexture.getInterpolatedV((double)(this.particleTextureJitterY / 4.0F * 16.0F));
            f3 = this.particleTexture.getInterpolatedV((double)((this.particleTextureJitterY + 1.0F) / 4.0F * 16.0F));
        }

        float f5 = (float)(this.prevPosX + (this.posX - this.prevPosX) * (double)partialTicks - interpPosX);
        float f6 = (float)(this.prevPosY + (this.posY - this.prevPosY) * (double)partialTicks - interpPosY);
        float f7 = (float)(this.prevPosZ + (this.posZ - this.prevPosZ) * (double)partialTicks - interpPosZ);
        int i = this.getBrightnessForRender(partialTicks);
        int j = i >> 16 & 65535;
        int k = i & 65535;

So how do I draw such a cube?

TominoCZ · August 11, 2016

well of course it doesn't have to be a coremod when you're just spawning particles using an emitter block..

The mod I've done for 1.7.10 is a coremod, I dd not find ANY way to make it not a coremod and still replace the original minecraft particle rendering.

If there is a way to do it using events, tell me how because I have no idea which even I could use.

TominoCZ · August 11, 2016

Yes, I tried to do that once but with the wrong method and also if you have your own EventHandler you can't override a method from a different class, because if the eventhandler class was extending that class, it would throw errors because of that. that's why I couldn't do it.

How do you override a method of a different class in your EventHandler then?

TominoCZ · August 11, 2016

well there is no method/constructor called isAlive in that class.....

TominoCZ · August 11, 2016

Why don't you show me what it's supposed to look like then

TominoCZ · August 11, 2016

OH I know what you meant by super... I'm sorry I'm tired I was looking at it the whole time

TominoCZ · August 11, 2016

When I remove the line super(arg0, arg1,...) it wants me to write that back in. It says the constructor has to explicitly invoke a method or something...

TominoCZ · August 11, 2016

Alright .. what constructor parameter should I initialize the Queue with....?

All I can pretty much do is initialize it like so: pq = null;..

I could add a Queue parameter to the constructor but then I would have to do another Queue field in the EventHandler...

TominoCZ · August 11, 2016

how do you replace the objects or how do you scan a Queue in general?

			Queue<Particle> qp = (Queue)f1.get(ParticleManager.class);

			Field f2 = ParticleManager.class.getDeclaredField("particleEmitters");
			Queue<ParticleEmitter> qe = (Queue)f2.get(ParticleManager.class);
			qe.add(new IParticleManager(e.getWorld(), null, qp));

			Minecraft.getMinecraft().effectRenderer.addEffect(new IParticleManager(e.getWorld(), null, qp));

TominoCZ · August 11, 2016

well then what the hell I did what you said how about you be more specific and actually help?!

This isn't even nescessary. All I wanted to know how to do is spawning a rotated cube not how to make it a normal mod.

So just stop that and rather tell me how to do what I actually came here for and be more specific this time because like this just telling me what I did wrong and not telling me what exactly to do, this not going anywhere.

Coud you please??

Thanks.

TominoCZ · August 11, 2016

I already did that. I now want to rotate them. i just dont know the math to calculate the positions of points of the vertexes. This task is just about math. As you see in the post, there's the code for rendering the cube and above the edited vertex rendering part, there is a piece of code commented out. That is what the code used to look like before.

TominoCZ · August 11, 2016

I know they're not.

Just be more specific with the explanation. You can sometimes post the corrected parts of the code.

and the "I" in the names are there because there is already a file called that without the "I". Not that that would matter, it's for better importing without a mistake when I hit Ctrl + O.

and the "I" in the names are there because there is already a file called that without the "I".

In standard nomenclature, the "I" denotes an interface.

TominoCZ · August 13, 2016

Alright, now the field changing actually works.

But whenever I create a new instance of IParticleManager(the new emittor) it says this(because I call super(null, null, null)):

TominoCZ · August 13, 2016

Well why don't you tell me how to do it then?

TominoCZ · August 13, 2016

grab Minecraft::effectRenderer and add a new instance of your ParticleEmitter class to ParticleManager::particleEmitters

That.

What do you mean by that?

what do I do with the effect renderer how do I add the particleemitter class to the particleEmitters with it? I don't get it.

TominoCZ · August 14, 2016

I know what that stuff is, what I don't understand is how minecraft effect renderer has anything to do with the queue just explain what I quoted some more with the effect renderer because you said:

grab Minecraft::effectRenderer and add a new instance of your ParticleEmitter class to ParticleManager::particleEmitters

How does that effectRenderer make any sense in there. What am I supposed to do with it.

Also I already posted the code that was adding the emitter you told me to create to the particleEmitters Queue and told you what error I'm getting.

TominoCZ · August 14, 2016

Well if you say that I never set any fields here, then how am I supposed to add anything to the queue?

MCenderdragon · August 14, 2016

by calling add. This is a normal Collection

TominoCZ · August 14, 2016

I know how to add stuff to collections / queues obviously

How about you finally post the part of the code

Is this what you wanted me to do?

ParticleManager particleManager = Minecraft.getMinecraft().effectRenderer;

or anything else?

Just post the correct code finally!

TominoCZ · August 14, 2016

so this should be right then:

@SideOnly(Side.CLIENT)
@SubscribeEvent
public void onEvent(EntityJoinWorldEvent e) {
	if (e.getEntity() == Minecraft.getMinecraft().thePlayer) {
		ParticleManager particleManager = Minecraft.getMinecraft().effectRenderer;

		try {
			Field field1, field2;

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

			System.out.println("[" + Main.name + "]: Getting fields..");

			if (Main.isDev() == true) {
				field1 = c.getDeclaredField("particleEmitters");
				field2 = c.getDeclaredField("queueEntityFX");
			} else {
				field1 = c.getDeclaredField("field_178933_d");
				field2 = c.getDeclaredField("field_187241_h");
			}
			field1.setAccessible(true);
			field2.setAccessible(true);

			Queue<ParticleEmitter> particleEmitters = (Queue<ParticleEmitter>) field1.get(particleManager);
			particleEmitters.add(new FBPParticleEmitter((Queue<Particle>) field2.get(particleManager)));
		} catch (Exception x) {
			System.out.println("[" + Main.name + "]: An error occured at onEvent(EntityJoinWorldEvent e):");
			x.printStackTrace();
		}
	}
}
