Solved Trouble setting Y value for a new location

Ok, se here's a snippet of my code:

Code:java

 Block block1 = new Location(loc.getWorld(), blockX, (double) 256, blockZ).getBlock();
Block block2 = new Location(loc.getWorld(), blockX, (double) 256, (blockZ + maxZ)).getBlock();
Block block3 = new Location(loc.getWorld(), (blockX+maxX), (double) 256, blockZ).getBlock();
Block block4 = new Location(loc.getWorld(), (blockX+maxX), (double) 256, (blockZ + maxZ)).getBlock();
 
CSPlugin.Log("block1 " + block1.getLocation());
CSPlugin.Log("block2 " + block2.getLocation());
CSPlugin.Log("block3 " + block3.getLocation());
CSPlugin.Log("block4 " + block4.getLocation());

• blockX is the base X value
• blockZ is the base Z value
• maxX is an added X value
• maxZ is an added Z value

essentially, i'm creating four locations in a square, all locations should have a height of 256. Only problem? All of the values are being entered properly into the location, but the Y value (256) is saving as 0...
Here's what's printed to the console immediately after I create the location:

Code:

block1 Location{world=CraftWorld{name=world}, x=-400.00, y=0.0, z=-137.0, pitch=0.0, yaw=0.0}
block2 Location{world=CraftWorld{name=world}, x=-400.00, y=0.0, z=-115.0, pitch=0.0, yaw=0.0}
block1 Location{world=CraftWorld{name=world}, x=-381.00, y=0.0, z=-137.0, pitch=0.0, yaw=0.0}
block1 Location{world=CraftWorld{name=world}, x=-381.00, y=0.0, z=-115.0, pitch=0.0, yaw=0.0}

It's printing that Y is 0, even though I'm setting it to 256 immediately before... Any ideas?

Edit: I also tried assigning 256 to a variable, and plugging that in instead (to match the X and Z), and that did not work either.

0-255, not 1-256. Got it. Works with 255.
