mahshidConditions and events
Games react to players: when someone touches a part, something happens. For that you need events and if checks.
What you’ll learn
- react to touches with Touched
- check with if whether a player touched it
- use else for the other case
Events: “when this happens, then …”
Touched fires as soon as something touches the part. With :Connect you say which function should run then.
if, then, else
Not only players touch parts – other blocks do too. With if you check whether the touching part belongs to something with a Humanoid (every character has one):
local part = workspace.MyPart
part.Touched:Connect(function(hit)
local humanoid = hit.Parent:FindFirstChild("Humanoid")
if humanoid then
part.BrickColor = BrickColor.new("Lime green")
else
part.BrickColor = BrickColor.new("Really red")
end
end)Just like in the code adventure
Remember ❓ If front is clear … else …? That is exactly the same idea: the program checks and then decides.
🛠️ Try it
Build a platform that turns green when a player stands on it. Bonus: make it turn grey again after 2 seconds (task.wait(2)).
🧠 Mini quiz
How do you know a player touched the part?
Every character has a Humanoid – other blocks don’t.
When does the else part run?
else is the “otherwise” case – just like in the code adventure.
