Question for a "nil value"[solved]

PostPosted: Thu Apr 14, 2016 14:57
by azekill_DIABLO
i'm actually doing a mod:

on_rightclick = function(self, clicker)

-- talk to the player
minetest.chat_send('BLABLABLAblaBLObla');
-- by right-clicking owner can switch Mob between follow and stand

if self.owner and self.owner == clicker:get_player_name() then


if self.order == "follow" then
self.order = "stand"
else
self.order = "follow"
end
end
end,})

i have problems with the underlined part?

In other words how to make talk a NPC on right-click?

Chat part:
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
local_chat(clicker:getpos(),"Sam: Let's go kick some Mob butt!",3)


Add this to api:
Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
         --Reese chat
         local_chat = function(pos,text,radius)
            if radius == nil then
               radius = 25
            end
            if pos ~= nil then
               local oir = minetest.get_objects_inside_radius(pos, radius)
               for _,p in pairs(oir) do
                  if p:is_player() then
                     minetest.chat_send_player(p:get_player_name(),text)
                  end
               end
            end
         end

I would need to see full init to figure that one out. maybe your follow code is missing something, or even a misplaced comma.

agg, you need to put the "reese chat" part in the api, not the init/

now i have the same error for the api.lua!THE SAME!

you have :
--Reese chat
local_chat = function(pos,text,radius)
if radius == nil then
radius = 25
end
if pos ~= nil then <this line need to change out ~ with =

at least I THINK that may be what is throwing the error, I could be completely wrong. If I am then full apologies

There's nothing wrong with "~=". It's the opposite of "==".

You should indent your code properly, right now it's unreadable. At the top of the file, you should start with an indent of 0. Every time you open a function, if statement, for/while loop, or some other code block you should indent in once. Also indent in for def tables.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.
Code: Select all
mob.register("name", {
    one = "two",
    three = "four",
    on_foo = function(player, pos)
        local pos2 = {x = pos.x, y = pos.y + 1, z = pos.z}
        minetest.chat_send_player(player:get_player_name(), "Hello!")
    end
})

function something(one, two, three)
    print(one .. " is " .. two .. " and " .. three)
end

that was super easy i solved it in 5 min without api.lua :)

just by adding this little function:

minetest.chat_send_player(clicker:get_player_name(), "MSG to the player")

Unfortunately, I was mistaken. I probably should not have offered any advice as I am just learning Lua myself. I figured I would at least try to help because I know what it is like to keep getting an error and going nuts going back and forth over the code to see what is missing or misplaced, (usually has to do with a comma haha)
Anyway, glad to see you figured it out
Cheers
