Ok, so today we will go over a very simple script piece by piece. It's probably one of the most used scripts on Roblox, but I think it's great instructional material for beginners. So, here we go. Post complaints, criticisms, and other stuff if you like.

-------------------------------------------------

Right, today we will be disecting a basic killing script. Many people use this to simulate lava in games so we will assume we are going to do the same. Now for your lava brick. To start off we need to define your function. A function name can be anything because it is a variable. So for now we will just name it "LavaBrick".

Code:

function LavaBrick(Hit)

Now you also put parenthesis's after functions, because they take function arguments or parameters. Now we need to tell your script what to look for so it can kill it. The function argument here is "Hit". This will later be defined as what hit the brick. So..

Code:

function LavaBrick(Hit)
LavaTarget = Hit.Parent:findFirstChild("Humanoid")

Right, so LavaTarget is a variable representing what hit the brick. In it is your function argument "Hit". So, if a Robloxian hit the brick, it would touch their legs. "Hit.Parent" Is in this case the parent of the legs which would be everything in the player model. So now we have the method ":findFirstChild()". Methods like this start with a ":" and also have parenthesis for arguments. So in the parenthesis we have "Humanoid". This would go to what hit the brick, find its parent, then search through the model for the first thing named Humanoid. Now the script knows what it is and has it tagged and saved as a variable.

Code:

function LavaBrick(Hit)
LavaTarget = Hit.Parent:findFirstChild("Humanoid")
if (LavaTarget ~= nil) then

So basically it's just checking to see if the Humanoid is not nil. By the way, nil means nothing or zero.

Code:

function LavaBrick(Hit)
LavaTarget = Hit.Parent:findFirstChild("Humanoid")
if (LavaTarget ~= nil) then
LavaTarget.Health = 0

Now inside the Humanoid their is a property called Health. This represents how much health your character currently has. So here, we are going inside the Humanoid and setting its health to zero.

Code:

function LavaBrick(Hit)
LavaTarget = Hit.Parent:findFirstChild("Humanoid")
if (LavaTarget ~= nil) then
LavaTarget.Health = 0
end
end
script.Parent.Touched:connect(LavaBrick)

Now, we have two ends here for a reason. The only things that need ends are functions, if's, and do's. We have one "function" and one "if" so we need two ends. Get it? Now the very last bit is the connection line. It's finding your script, then its parent which would be the brick. Now it uses the "Touched" event. When you see functions with the variable "Touch" or "Touched" it does not mean that is an event. The Touched event is for any type of brick being touched. So it finds the scripts parent, which is the brick, and connects the Touched function. Then there is ":connect(LavaBrick)". This does exactly what it says, it connects the function to the connection line so the script can run. Without a connection line, scripts won't run. I hope you learn from this and the last section of coding is the actual working script. You have to put it in a brick, then copy the brick and step on it. Learn more about scripting for special effects.

nice tut bro! :)

Thanks. :)

k I will then XD

tl:dr

Well, I'm now a wiki writer so I'm replacing the old lava tutorial with this.

awesome!
