| | I play on Achaea and I'm trying to make a fairly simple but tedious alias. I have two triggers that set variables for "Full health" and "Current health" what I need to do now is figure out a way to set a variable for the difference of the two. My scripting is in Lua, but I'm not sure if this would be a Lua or MUSHclient command. Any help would be great, thanks! | | Top |

| | I looked through that a little bit. But what I need is something like Print (5 - 4) --> 1 except I need 1 to be set as the variable content, and I'm not sure how to do that. | | Top |

| local crh = tonumber(GetVariable("crh"))
local health = tonumber(GetVariable("health"))
local diffh = health - crh
This is what I have so far, I need another line that can either change the diffh variable into a MUSH variable so I can retrieve the number. Or a line that could send the number directly to the game, but not as a print or note. | | Top |

| I think I figured out that I need to serialize the variable? But I'm not totally sure how I do that. I looked at this post http://www.gammon.com.au/forum/?id=4960, which probably is obvious to anyone who knows much about coding, heh. I'm just not sure what all I need to do to serialize this one variable?
Or if there's an easier/more obvious way to do this, I'll take that suggestion too! | | Top |

| It isn't as complicated as all that. Lua knows that if you try to subtract two things they must be numbers, so you don't need "tonumber". First, look at this:
print (GetVariable ("crh") - GetVariable ("health"))
That prints the difference.
You can also use the "var" module to make a pseudo-table that lets you access MUSHclient variables easily:
require "var"
print (var.crh - var.health)

You don't really need that unless you want it for some reason, but this is how you could do it:
require "var"
diffh = var.crh - var.health -- Lua variable diffh
var.diffh = diffh -- MUSHclient variable diffh

Just use "Send", like this:
require "var"
Send ("say My health has changed by " .. var.crh - var.health)
