When you stand on a block and look down at it, if you move the coordinate changes half way through the block.
Even when you have four blocks around the one block, the coordinates still change.
my slime pads are 18 x 18 because of this.
when i've been building I have got my measurements wrong because of this also haha.
Does anyone know how to tell what the x and z coordinates of a block are?
Blocks aren't on coordinates, they are in between them. That's why it seems to change in the middle. When you are standing ON a block you are actually between coordinates.
For making your slime pads, look at where the lines between the blocks are and count the blocks between the lines.
For example, one block would be between coordinates 1 and 2.
the coordinates on the map aren't very accurate, i cant tell if the x and z coordinates are on the block below me or next to me, in a four block space, the coordinates are all the same in some spots, have a look, this is on the xbox360 edition

What he said, think of the lines on the edge of each block as a grid. X and Z are the coordinates of each line, not the block. I'm sure you've seen a real map with coordinates before, they don't start the coordinates half a meter from each border. Why would they in Minecraft, let alone any game?
Yeah. What you want to do is get your map, and you will have to move around while looking at it.
Say if you start around 0, move back and forth in two directions and find the line where it switches between 0 and 1. The block on one side is in the 1 coordinate, and the one on the other side of the line is in the 0 coordinate. Do this for the other two directions to find your block to be the first corner of your pad.
Then go down each side. You'll have a block that is between 1 and 2, one between 2 and 3, one between 3 and 4... etc. all the way up to a block between 15 and 16, which is where you stop and go the other direction until you have a square.
Regarding the Y coordinate: we had some extensive discussions in other threads, and determined that the Y coordinate showing in the map corresponds to the block directly above the player's head (due to a rounding error acknowledged by 4J). This is in sharp contrast to the PC version, where the Y coordinate shows the fractional height of the player's eyes. To find the layer of the block you are standing on, subtract 3 from the Y coordinate.
So standing on the ocean shore, the map shows Y=66. That makes your head at layer 65, your legs at layer 64, and the top block of the ocean layer 63 (which matches the ocean layer of PC version 1.6. Sea level changed to 62 in a later PC release).
Similarly, standing on the edge of the below-ground lava lakes, the map shows Y=13. This puts the top layer of lava at layer 10, which matches the PC version.
One other difference to be aware of is the bedrock layers: the XBox has 2 fewer bedrock layers (layers 0, 1, and 2) than the PC version (layers 0 through 4). This means you have to be cautious about people telling you that something is "x layers above bedrock" based on the PC. If they are talking about the bottom bedrock layer, this is accurate. If they are talking about the top bedrock layer, you have to adjust by 2. (Curiously, the tutorial map looks like it must have been created on the PC, since it appears to have more bedrock layers than Xbox-generated worlds.)
haha i didn't think of it being the lines between the blocks thanks
that's the key, once you understand that, correlating blocks to map coordinates becomes much easier. But it sure would've made more sense to have each block be a integer coordinate (for the players, perhaps not for the programmers).

Map doesn't show the coordination. Pressing F3 will show where you are
X
Y
Z
is the order.
no you are on the 360 forum not pc no f3 on 360

Retired StaffWhat he said, think of the lines on the edge of each block as a grid. X and Z are the coordinates of each line, not the block.

Best way to see this is to dig a 1x1 hole and jump in. Pull out the map and move corner to corner.
Being a block or two off will not hurt your slime pad.

The block on one side is in the 1 coordinate, and the one on the other side of the line is in the 0 coordinate.
