[1.7.10]Testing which way the player is looking

[ryancpexpert]

I am working on a Zelda mod, and I am trying to add a item that will allow the player to create a block using it. I am currently using entities to determine where it should place the block, however, I am trying to make it not depend on the entity, and only on the item, as I only want the player to be able to spawn the block 1 block in front of them. How would I go about testing which way the player is facing so I can determine how to set the block in the code?

If you have an item class that you are using, override 'onItemUse' - it gives you the coordinates of the block clicked, the side that was clicked, and even more precise float coordinates for the exact position if needed.

You can also access the player entity's rotation.

[coolAlias]

That facing method will fail (or at least not give expected results) if the player is looking up or down, though - if the item works at a distance greater than that of block-clicking, then you ought to use ray tracing to find the block hit by the player's look vector.

[coolAlias]

Yes, and it will probably be exactly what is needed - just thought I'd point out that depending on the requirements (up/down possibilities), it may not be enough

i solve this making something complicated

 

meta return 0 when looking up

meta return 1 when looking down

meta return 2 when looking south

meta return 3 when looking north

meta return 4 when looking east

meta return 5 when looking west

 

meta return 6 when error

 

 

first get the block xyz coordinates  sum  steve xyz coordinates and whit results set face of block steve is looking at

 

 

mi methods starts like

 

 

//block class

public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase steve, ItemStack p_149689_6_){

int meta=util.meta(world, steve);

System.out.println("util.meta(world, steve)="+meta);

 

}

 

//##################################################

//class util

 

public static int meta(World world, EntityLivingBase steve){

                          // Position de steve , pocision del blocke

ArrayList<Integer> lia = new ArrayList<Integer>();

ArrayList<Integer> lib = new ArrayList<Integer>();

lia.clear();

lib.clear();

 

lib=util.coordenadaDeBlockeEnFocol(world, 10);

lia.add((int) steve.posX);

lia.add((int) steve.posY);

lia.add((int) steve.posZ);

 

 

int x=lib.get(0)-lia.get(0);

int y=lib.get(1)-lia.get(1)-1;

int z=lib.get(2)-lia.get(2);

 

System.out.println("x="+x+" y="+y+" z="+z);

 

if ((x>0)&&(z<0)){return 4;}//return 10;}

if ((x<0)&&(z<0)){return 3;}//return 9;}

 

if ((x<0)&&(z>0)){return 5;}//return 8;}

if ((x>0)&&(z>0)){return 2;}//return 7;}

 

if ((x<0)&&(z==0)){return 5;}

if ((x>0)&&(z==0)){return 4;}

 

if ((x==0)&&(z<0)){return 3;}

if ((x==0)&&(z>0)){return 2;}

 

if ((y<0)){return 1;}

if ((y>0)){return 0;}

 

return 6;

 

}

public static ArrayList<Integer> coordenadaDeBlockeEnFocol(World world,int distancia){

//System.out.println("###coordenadaDeBlockeEnFocoL");

 

ArrayList<Integer> lin =new ArrayList<Integer>();

 

//      x          y          z

//lin.add(0);lin.add(0);lin.add(0);

 

 

MovingObjectPosition mop = Minecraft.getMinecraft().renderViewEntity.rayTrace(distancia, 1.0F);

//System.out.println("###mop="+mop);

if(mop != null)

{

    int blockHitSide = mop.sideHit;

    lin.add(2,fz);

}

//

// int x=lin.get(0);

// int y=lin.get(1);

// int z=lin.get(2);

// if (world.isAirBlock(x,y,z)) {System.out.println(">>>>>### el blocke x="+x+" y="+y+" z="+z+" es aire");}

 

//  System.out.println("x="+lin.get(0)+" y="+lin.get(1)+" z="+lin.get(2));
