Grid updated

Updated Grid by gbl. The original mod is end of life and I got request to update this mod...
if u find a bug/ crash, report to my discord/ github.

original discription

Sometimes you want to place blocks in a regular pattern, so you need to count blocks, and if you mess up once, the error propagates to all subsequent blocks.

This mod displays a grid-like overlay over the world, with configurable spacing, so the blocks you're interested in get highlighted automatically.

For example, you're building a railroad and want to place a powered rail ever 20th block. Type /grid 20, walk to the first powered rail, type /grid here (or press the c button, can be configured), and the mod will highlight every 20th block from where you're standing.

Or, if you want to place torches in an area to prevent spawns, type /grid 5 - this highlights every 5th block; placing torches on each of them will light everything up enough.

You can switch between block mode (to highlight blocks to place stuff on) or line mode (to display borders; for example /grid chunks followed by grid lines will turn Grid into a chunk border highlighter), have the y-coordinate of the display floating with the player or fixed, and choose different X and Z spacings if you want that.

commands

/grid show and /grid hide: show/hide the grid, bound to the B key.

/grid here: set the origin of the grid to where the player is standing. Bound to C (for center)

/grid blocks: set Block mode: show blue squares above marked blocks

/grid lines: set Line mode: show yellow lines to the N/W of marked blocks

/grid chunks: set X and Y spacing to 16 and the origin to chunk borders. Use together with /grid lines to get a chunk border display that's less intrusive than F3-G

/grid : and are numbers; set the grid spacing to n in X direction and m in Y direction

/grid : set the grid spacing to n in both horizontal directions

/grid fixy: toggle between floating the y coordinate of the grid with the player, or fixing it to where the player stands when you use the command. Bound to the Y key.

/grid spawns: show possible mob spawn locations

/grid circles: shows circle overlays. In line mode, this shows regular circles; in block mode, it tries to find and mark the blocks you should build on to get a circle. Obviously, this can't work well with very small diameters, for example, trying to mark a 3x3 circle will give you a square.

/grid distance : sets the range in blocks, that the grid is rendered around you. If you use very large spacings/circle diameters, you need to adjust this too. Be careful though, high values for distance absolutely kill your framerate when you turn spawn locations on.

/grid biome : draw a marker on all blocks in a certain biome. For example, /grid biome river helps when you want to build a drowned or squid farm. (Only with Grid version 1.5+).

/grid hex: Draw a hex grid. In block mode, you get the corners of each hex; in line mode, you get lines around the hexes. (Only with Grid version 1.6+)

All keys can be reconfigured using the standard Controls UI.
