So from a line code of location below, it defines a location: Code (Text): Location loc = new Location(world, x, y, z); Location clone = loc.clone(); However I was wondering how to correctly obtain the block of player head, feet and the block player is standing on. I have tried the following code, but it seems always getting the wrong block: Code (Text): Block head= w.getBlockAt(cloc.add(0,1,0)); Block feet = w.getBlockAt(cloc.subtract(0,1,0)); Block under = w.getBlockAt(cloc.subtract(0,2,0)); What it gives was a wrong result Code (Text): loc: x#0, y#140, z#0 head: x#0, y#141, z#0, [email protected] feet: x#0, y#140, z#0, [email protected] under: x#0, y#138, z#0, [email protected] Could anyone give some suggestion on this?
Code (Java): BlockFace down = BlockFace.DOWN; for (int i = 0; i < 3; i++) { Block block = location.getBlock().getRelative(down); location = block.getLocation(); } you could do something like this
As you can see, your under location is one block too far on the y axis. Just substract one less block for this location and you will be good (probably)
Thanks, however I prefer using less loops to keep the server not heavily loaded. Ah, I misread the subtraction, thanks for pointing out for that
Location is a mutable object, meaning its values it contains can be modified. Something like Location#subtract is mutating those values and returning itself (not a new object). Code (Java): Location location = new Location(world, 0, 140, 0); Location head = location.add(0,1,0); Location feet = location.subtract(0,1,0); Location under = location.subtract(0,2,0); All 4 of these variables are now referencing the same object, and that object has a Y value of 138. So checking Y on any of those variables will yield 138. Code (Java): Location location = new Location(world, 0, 140, 0); Location head = location.clone().add(0,1,0); Location feet = location.clone(); Location under = location.clone().subtract(0,1,0); Now there are 4 different objects with different Y values (other than feet being the same Y value as the original location). Changing the values of any of these objects will not effect any of the others. head has Y of 141, feet has Y of 140, and under has Y of 139.
