All mods seem to have no effect, or cause PZ to crash on load

[Damienknight]

(I posted this under the Tutorial thread, but thought it might fit better here).

 

I cannot get any .lua based mods to work.

 

Specifically I tried the dry towels mod, and couple attempts at modding myself.

 

Here is the simple intro mod (that for me does nothing):

 

function sayHello()

playerlog = getSpecificPlayer(0);

playerlog.Say("Hello");

end

 

Events.EveryTenMinutes.Add(sayHello);

 

 

I placed this inside of my mods folder %%Zomboid\mods\helloworld\media\lua

 

I setup the mod.info and poster.png in the helloworld root folder.

 

The mod info file:

 

name=Hello World (1.0.0)

poster=poster.png

description=Test where player 0 says Hello World every 10 in game minutes

id=helloworld

url=www.google.com

 

 

When booting, the mod appears in the mod list, with poster working.  I double click to activate (checkmark appears).

 

I start a Beginner survival game.  I would expect to have my character say 'Hello' every 10 minute in game interval.

 

Any advice?

What is playerlog?

What is playerlog?

A variable i am creating, which points to a player, whom I want to force to Say things.

There's a subtle error in your script.

You need to use "player:Say("Hello");" instead of "player.Say("Hello");".

The difference is a colon ( instead of a dot (.) between player and Say.

This is why I shouldn't post after waking up, BlindCoder. Totally missed it.

So when calling Events Add, I should use a period but when calling the Say function I should use a Colon?  What is the rule for when to use a colon and when to use a period?

 

Events.EveryTenMinutes.Add(sayHello);  <-- Use a Period for the ADD method?

 

player:Say("Hello");  <-- Use a Colon for the Say method?

You use a colon when you are calling a method of an instantiated object (something that has a "self" reference).

You use a dot when you use a function stored in a table.

 

I agree that it is not always obvious, and i'm honestly not sure why the Events.*.Add don't have a colon :/
