Hello, I am a newbie to Lua and I've been trying to fix this script for about a while and I can't figure it out. Basically I made a button that will make something transparent and turn on a point light when it's clicked, but I don't know how to turn the light off and restore the transparency when I click the button again, how would I do this? Here's my code.
function clicked(playerWhoClicked) Workspace.Shadows1.Transparency = 1 Workspace.shadowlight.PointLight.Brightness = 5 end script.Parent.ClickDetector.MouseClick:connect(clicked)
'if' and 'else' statements are wonderful things. It lets the program knows if a thing is in this condition, do these set of actions.
You can simply have your function laid out like this:
Boolean = true function ExampleFunc() if Boolean == true then Boolean = false elseif Boolean == false then Boolean = true end end
You can then shorthand the 'if'/'else' statement to save time and become more efficient (very important, and you will understand why).
if Boolean then Boolean = false elseif not Boolean then Boolean = true end
not is equivalent to false or nil*. Consequently, the absence of
not will make it true*.
not actually means the opposite of a boolean value. Remember in math: if you multiply a negative number with another negative number, you will yield a positive number. So
not true == false
not false == true
Since the datatype we're manipulating is a boolean value, you can shorten the
elseif statement into an
else Boolean = true end
Because originally, the if statement says if the Boolean is true. Elsewise, it will be false.
To implement that knowledge into your script, you can have a static boolean variable and the set of ifs and elseifs.
On = false -- Where your function starts if On == false then On = true Workspace.Shadows1.Transparency = 0 Workspace.shadowlight.PointLight.Enable = true -- You can preset your PointLight's brightness. else On = false Workspace.Shadows1.Transparency = 1 Workspace.shadowlight.PointLight.Enable = false end
