Commands/testforblocks

Tests whether the blocks in two regions match.


 * Syntax


 * Java Edition


 * Pocket Edition


 * Color added to make reading easier.


 * Arguments


 * x1 y1 z1 and x2 y2 z2 (PE:  and  )
 * Specifies two opposing corners of the region to use as the pattern to test for (the "source region"). x1, z1, x2, and z2 must all be between -30,000,000 and 30,000,000 (inclusive, without the commas), and y1 and y2 must be between 0 and 255 (inclusive). May use tilde notation to specify coordinates relative to the command's position. The number of blocks in the source region must not exceed 524,288.


 * x y z (PE: destination: x y z )
 * Specifies the lower northwestern corner (the corner with the most-negative values) of the region to be checked (the "destination region"). x and z must both be between -30,000,000 and 30,000,000 (inclusive, without the commas), and y must be between 0 and 255 (inclusive). May use tilde notation to specify coordinates relative to the command's position. Source and destination regions may overlap.


 * mode (PE: mode: string) (optional)
 * Specifies how to match blocks. Must be one of:
 * — every block in the source and destination regions must match exactly.
 * — air blocks in the source region will match any block in the destination region.
 * If not specified, defaults to.


 * Result


 * Fails if the arguments are not specified correctly, or if the source and destination regions do not match.


 * On success, returns the number of matching blocks (the total number of blocks in  mode, or the number of source region non-air blocks in   mode).
