TalkAction /up and /down with parameter

[Relicz]

Another default script edit I thought I'd share. It's pretty inconsequential, but I think it's a nice quality of life tweak
I wanted to do things like "/up 2" to go up 2 floors rather than do the command twice, so I wrote a quick edit. Of course, it still works without a parameter, and just takes you up/down 1 floor as it did previously.

First, since we're adding a parameter, make sure you add a separator to the commands in your talkactions.xml for it to work

<talkaction words="/up" separator=" " script="up.lua" />
<talkaction words="/down" separator=" " script="down.lua" />

Nice! So now, let's update our up.lua and down.lua scripts

up.lua

function onSay(player, words, param)
    if not player:getGroup():getAccess() then
        return true
    end

    local position = player:getPosition()
    
    -- if we have a number param, use that. if not, just go up by 1
    local value = tonumber(param)
    if not value then
        position.z = position.z - 1
    else
        position.z = position.z - value
    end
        
    player:teleportTo(position)
    return false
end

down.lua

function onSay(player, words, param)
    if not player:getGroup():getAccess() then
        return true
    end

    local position = player:getPosition()
    
    -- if we have a number param, use that. if not, just go down by 1
    local value = tonumber(param)
    if not value then
        position.z = position.z + 1
    else
        position.z = position.z + value
    end
    
    player:teleportTo(position)
    return false
end

Enjoy!
