[1.7.2] Motion and AABB

[TLHPoE]

I'm making a block that acts like a fan, and uses meta data to orientate itself.

package fans.tileentity;

import java.util.List;

import net.minecraft.entity.Entity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.AxisAlignedBB;
import fans.block.BlockFan;

public class TileEntityFan extends TileEntity {
@Override
public void updateEntity() {
	if(BlockFan.isPowered(worldObj, xCoord, yCoord, zCoord)) {
		int current = worldObj.getBlockMetadata(xCoord, yCoord, zCoord);
		switch(current) {
		case (0): {
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 1, zCoord + );
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionZ += ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
		}
		case (1): {
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 8, yCoord + 1, zCoord - 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionX += ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
		}
		case (2): {
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 1, zCoord - );
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionZ -= ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
		}
		case (3): {
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord - 8, yCoord + 1, zCoord - 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionX -= ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
		}
		case (4): {
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 8, zCoord + 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionY += ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
		}
		case (5): {
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord - 8, zCoord + 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionY -= ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
		}
		}
	}
}
}

 

For some reason, when its oriented in a horizontal position and I'm standing on top of it, it slows me down. Also, when I jump, I get launched as if the fan oriented upwards.

Hi

 

If you're intending for your metadata to match minecraft's "side", you've got them mixed up.

Oh, I just used my own meta data. It orientates itself properly.

[TLHPoE]

Here's some updated code:

package fans.tileentity;

import java.util.List;

import net.minecraft.entity.Entity;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.AxisAlignedBB;
import fans.block.BlockFan;

public class TileEntityFan extends TileEntity {
@Override
public void updateEntity() {
	if(BlockFan.isPowered(worldObj, xCoord, yCoord, zCoord)) {
		int current = worldObj.getBlockMetadata(xCoord, yCoord, zCoord);
		switch(current) {
		case (0): { //Front
			System.err.println("CURRENT: " + current);
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 1, zCoord + 9));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionZ += ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
			break;
		}
		case (1): { //Right
			System.err.println("CURRENT: " + current);
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 9, yCoord + 1, zCoord + 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionX += ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
			break;
		}
		case (2): { //Back
			System.err.println("CURRENT: " + current);
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 1, zCoord - );
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionZ -= ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
			break;
		}
		case (3): { //Left
			System.err.println("CURRENT: " + current);
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord - 8, yCoord + 1, zCoord + 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionX -= ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
			break;
		}
		case (4): { //Top
			System.err.println("CURRENT: " + current);
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord + 9, zCoord + 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionY += ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
			break;
		}
		case (5): { //Bottom
			System.err.println("CURRENT: " + current);
			List entities = worldObj.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(xCoord, yCoord, zCoord, xCoord + 1, yCoord - 8, zCoord + 1));
			if(!entities.isEmpty()) {
				for(Object obj : entities) {
					if(obj instanceof Entity && !((Entity) obj).isSneaking()) {
						((Entity) obj).motionY -= ((BlockFan) this.getBlockType()).getPower();
					}
				}
			}
			break;
		}
		}
	}
}
}

 

I got the bug fixed, I forgot to add breaks in the cases.

 

My new problem is that the front, right, and top code work, but not he back, left, and bottom code.

[TLHPoE]

Fixed it, I don't know exactly what was wrong, but my friend suggested moving the x/y/z coord changes in the nonworking sides to the minimum coords.
