Hello everyone, recently I've been receiving a few DM's about how to learn scripting etc..., so I decided to open this topic to maybe provide help to those who are willing to learn Lua and maybe push those who are just thinking about it and hesitating.
Part 1:
First of all, I can't explain better than those links, so you should read them
carefully before reading the next part of this topic:
1-
https://wiki.multitheftauto.com/wiki/Scripting_Introduction 2-
https://www.lua.org/manual/5.1/3-
https://forum.mtasa.com/topic/34453-lua-tutorials-manuals/After reading those links carefully, you should now know what 'debugging' is. Infact, debugging may help you fix the errors yourself 99% of the time, here is a link to know what debugging is:
-
https://wiki.multitheftauto.com/wiki/DebuggingNow you can go ahead and save this link in your browser:
https://wiki.multitheftauto.com/wiki/Main_PageThe last link is the most important of all, it's where you'll be looking every time you are making something(a script).
-------------------------------------------
Part 2: (Only read this if you totally understood/read Part 1)
Now, you should have a general idea about scripting/Lua, so we'll be making a couple scripts to get you started with.
We are gonna make a script which outputs "blabla logged in" whenever a player logs in, and another for when a player logs out.
First things first, we are gonna go here(
https://wiki.multitheftauto.com/wiki/Server_Scripting_Events) and look for an event that triggers when a player logs in, which is gonna be "onPlayerLogin". Let's go:
function playerLogin() -- function name should always be camel case(this is only for Lua)
local playerName = getPlayerName(source) -- get the name of the player who logged in with "getPlayerName"
outputChatBox("JOINQUIT: "..playerName.." has logged in!", root) -- We output a text to everyone online using "outputChatBox"
end
addEventHandler("onPlayerLogin", root, playerLogin) -- Our event handler which will trigger this function every time a player logs inFor when a player logs out, we will need an event for that, we go to wiki and we will find "onPlayerLogout", let's go:
function playerLogout() -- function name should always be camel case(this is only for Lua)
local playerName = getPlayerName(source) -- Here we are getting the name of the player who logged out with "getPlayerName"
outputChatBox("JOINQUIT: "..playerName.." has logged out!", root) -- We output a text to everyone onine using "outputChatBox"
end
addEventHandler("onPlayerLogout", root, playerLogout) -- Our event which will trigger this function every time a player logs outNow let's make a script which will give a random player 50,000$ everytime you type /giverandomcash and output a message to the random player to inform him about the money.
We go to the wiki(as always) and we search for a function to get a random player, which will be
https://wiki.multitheftauto.com/wiki/GetRandomPlayer, and a function to give the player money, which will be
https://wiki.multitheftauto.com/wiki/GivePlayerMoney, finally to inform we will use outputChatBox which we have seen earlier. Let's go!
function giveRandomMoney(thePlayer, command)
local randomPlayer = getRandomPlayer() -- we get a random player
givePlayerMoney(randomPlayer, 50000) -- we give the money
outputChatBox("You got lucky and won 50,000$", randomPlayer, 0, 255, 0) -- we output a text to the player to inform him about the money
end
addCommandHandler("giverandomcash", giveRandomMoney) -- Our function will trigger once this you type this command--------------------------------------
Part 3:
Here are two tasks for you to test yourself!
Task1:
- Make a script which removes the player's head once he executes the command '/head', and give it back again when he executes the same command.
Task 2:
- Create a pickup and make it that when a player enters the pickup, he will get 1,000$
You can then post your work here, same if you face any errors/questions, and someone(or me) will hopefully answer you
