Bow HUD with rangefinder

// You need the FarHit module for the range finder to work
// http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/mods-discussion/1405026-macro-keybind-mod-modules
// To install a module, drag the .jar file into .minecraft/macros/modules

// You need to create a label for this to work.

// Go to Macro Mod keybind editor menu
// Click the icon on the very top left corner of the screen, then "Gui Editor".
// Double-click on "ingame" in the left menu. http://i.imgur.com/Cq2bL7p.png
// On the bottom left, click "Button panel commands", then select "Adjust grid".
// Click on the far left column in the grid, then change the grid settings to Rows: 22, Columns: 15, Column Width: 48.
// This is for a 1440x900 monitor. You will need to tweak this to fit your monitor. FOV effects this greatly as well; it's calibrated for 90 FOV.
// In button panel commands, select "Add label", then click 2 cells below the center cell.
// Set Control Name to "archerprogress", leave label text and binding blank. Click on Foreground colour, and set the opacity to 0 (drag the slider to the bottom). Do the same for background colour.
// Set text align to "top centre", and uncheck shadow.
// Press OK, then click and drag the bottom of the cell to make it 3 cells high. http://i.imgur.com/qkDFLVN.png

// Bind this macro to the onjoingame event, and it will run in the background, only displaying the HUD when you have a bow selected.
