[1.7.10]How do I make a block suck in entities?

Recommended Posts

I have recently been trying to make a black hole but I cannot find code for it ANYWHERE! I tried " double radius = 5;

        List<EntityItem> items = world.getEntitiesWithinAABB(EntityItem.class, ep.boundingBox.expand(32, 32, 32)); //The area to pull items from (change 32 to any number)

        for(EntityItem it : items){

            double distX = ep.posX - it.posX; //Move those items!

            double distZ = ep.posZ - it.posZ;

            double distY = it.posY+1.5D - ep.posY;

            double dir = Math.atan2(distZ, distX);

            double speed = 1F / it.getDistanceToEntity(ep) * 15; //Adjust the speed here (change 15)

 

            if (distY<0)

            {

                it.motionY += speed;

            }

 

            it.motionX = Math.cos(dir) * speed;

            it.motionZ = Math.sin(dir) * speed;

        }

}"

but that just gives me a ton of errors saying it cant find distx,y and z.

I really need some help! any kind is appreciated.

do you think you could supply me with the code for the sucking entities and killing them thing? I would really appreciate it! If you want, I could give you a link to a custom model of Sonic the Hedgehog and Tails, all ready to be animated and put in-game in return of the code.

Not how it really works around here, would be nice, but if that was the case not many would learn.

 

You can post the class in

[code] {/code]

 

Seems like you have a rough idea on how to do this, just some error troubles.

  • 1 year later...

from my experience it is wise to avoid using sin/cos at all costs if possible as they are heavy on processing, you might wanna read up some on linear algebra to help you aswell

I know this post is over a year old but to be honest, I tried to take that from the Vacuum Hopper in Open Blocks. I feel kind stupid but I really need this code for a Black Hole. I have all the textures ready as well as the custom model.

 

Also, someone PLEASE supply me with the code. Of course, I'll give proper credit too.

I have tried to create a blackhole myself some time ago. Even though the code i used to "suck" entities inside it worked i never got it's rendering to work properly. I can supply you with the code of my blackhole but you have to work through the rendering process yourself.

 

Code:

 

public class blackHoleTE extends TileEntity implements IUpdatePlayerListBox{

private int Mass;

@Override
public void update() {

	List<Entity> EntitiesAround = this.worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.fromBounds
			(this.getPos().getX() - 10 - Mass / 10, this.getPos().getY() - 10 - Mass / 10, this.getPos().getZ() - 10 - Mass / 10,
			this.getPos().getX() + 10 + Mass / 10 + 1, this.getPos().getY() + 10 + Mass / 10 + 1, this.getPos().getZ() + 10 + Mass / 10 + 1));

	for(Entity e : EntitiesAround){
		double motionX = this.getPos().getX() - (e.posX + 0.5);
		double motionY = this.getPos().getY() - (e.posY + 0.5);
		double motionZ = this.getPos().getZ() - (e.posZ + 0.5);

		e.motionX = motionX * 0.1F;
		e.motionY = motionY * 0.1F;
		e.motionZ = motionZ * 0.1F;

	}

	List<Entity> ToClose = this.worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.fromBounds
			(this.getPos().getX() - 1 , this.getPos().getY() - 1 , this.getPos().getZ() - 1,
			this.getPos().getX() + 2, this.getPos().getY() + 2, this.getPos().getZ() + 2));

	for(Entity e : ToClose){
		if(e instanceof EntityItem){
			Mass++;
			e.attackEntityFrom(DamageSource.cactus, 7.5F);
		}else{
			e.attackEntityFrom(DamageSource.cactus, 7.5F);
		}
	}

	if(Mass >= 500){
		if(!worldObj.isRemote){
		worldObj.destroyBlock(this.pos, false);
		worldObj.createExplosion(null, this.getPos().getX(), this.getPos().getY(),
				this.getPos().getZ(), 100F, true);
		}
	}
}

@Override
public void writeToNBT(NBTTagCompound compound) {
	compound.setInteger("Mass", Mass);
	super.writeToNBT(compound);
}

@Override
public void readFromNBT(NBTTagCompound compound) {
	compound.getInteger("Mass");
	super.readFromNBT(compound);
}

}

 

 

My blackhole is made so it adds an explosion after it takes up to much entities inside it. Remove the parts of code that do that.

Alert: supplied code is 1.8ish.  1.7.10 does not require IUpdatePlayerListBox and all

pos

and

Blockpos

objects should be some variant of

x

,

posx

, or

xCoord

.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

How do xp orbs get drawn toward a player? Even if the movement is calculated by each orb itself, you should see useful examples of vector math and entity search there that you can adapt to your tile entity.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

    • Hello. I've been having a problem when launching minecraft forge. It just doesn't open the game, and leaves me with this "(exit code 1)" error. Both regular and optifine versions of minecraft launch just fine, tried both with 1.18.2 and 1.20.1. I can assure that my drivers are updated so that can't be it, and i've tried using Java 17, 18 and 21 to no avail. Even with no mods installed, the thing won't launch. I'll leave the log here, although it's in spanish: https://jmp.sh/s/FPqGBSi30fzKJDt2M1gc My specs are this: Ryzen 3 4100 || Radeon R9 280x || 16gb ram || Windows 10 I'd appreciate any help, thank you in advance.
    • Hey, Me and my friends decided to start up a Server with "a few" mods, the last few days everything went well we used all the items we wanted. Now our Game crashes the moment we touch a Lava Bucket inside our Inventory. It just instantly closes and gives me an "Alc Cleanup"  Crash screen (Using GDLauncher). I honestly dont have a clue how to resolve this error. If anyone could help id really appreciate it, I speak German and Englisch so you can choose whatever you speak more fluently. Thanks in Advance. Plus I dont know how to link my Crash Report help for that would be nice too whoops
    • I hosted a minecraft server and I modded it, and there is always an error on the console which closes the server. If someone knows how to repair it, it would be amazing. Thank you.
