checking if entity on position


seppitm

Recommended Posts

i have the following problem:

public static boolean setBlock(EntityPlayer player, int x, int y, int z, int id, int meta)
{
	boolean rv = false;
	if(player.worldObj.isAirBlock(x, y, z) && player.canPlayerEdit(x, y, z))
	{
	player.worldObj.setBlockAndMetadataWithNotify(x,y,z,id,meta);
	return true;
	}
	return rv;
}

 

it checks if the block is air but i cant check if an entity stands on the block. how can i check this?

well you can get close to it by checking if the distance to block is less or equal to one.

 

public boolean collectItem(EntityItem targetItem)
{
 if(targetItem == null)
    {
	    targetItem = findClosestItem(this.posX, this.posY, this.posZ,30);
    }
    else
    {
    	if(!targetItem.isEntityAlive())
	    {
	    	targetItem = null;		    	
	    }	
    }
    if(targetItem != null)
    {
    	
    	PathEntity PathToItem = this.worldObj.getPathEntityToEntity(this, targetItem, 30, true, false, false, true);
	    if(hasPath()){
		    this.setPathToEntity(PathToItem);
		    this.moveSpeed = 1.0F;
		    [b]if(targetItem.getDistanceSq(this.posX,this.posY,this.posZ) < 2)[/b]
		    {
			 targetItem.setDead();
			 //TODO add item to inventory
			 targetItem = null;
		    }				 
	    }
	    else
	    {
	    	this.moveSpeed = 0.23F;
	    }
    }
	return false;
}

this is the code i use for collecting items. It has cod for checking distance to target.

i dont have any entity... i have only X, Y & Z Coordinates and i whant to find out if there is a entity in this "block"

oh so you want to find if its just above the block.

//your'll have to fiddle with the bound box size to find only items above
AxisAlignedBB bounds = AxisAlignedBB.getBoundingBox(x,y+1,z, x+1,y+2,z+1);
//change EntityItem too the entity you want to find
List<EntityItem> items = par1World.getEntitiesWithinAABB(EntityItem.class, bounds);
if(items.size > 0)
{
//there is something above block
}

 

there is more likely an easier bit of code that just checks of the spot you want to place is clear, or else placing normal block would cause issues. Check line 3461 in World.class and the ItemBlock.class

    • It depends on the data you want to save, but generally speaking you should use some custom Player Capabilities, attach to the Player and use them to store/retrieve any kind of data you want. You can find how to make them work for 1.20.x in the documentation here: https://docs.minecraftforge.net/en/latest/datastorage/capabilities/
