A Nice Health Pad

Guest

Code:: local heal = 20 --How much it heals
local waiting = 2 --How long before can be used again

local debo = false

function onTouch(hit)
if hit.Parent.Humanoid ~= nil and debo == false then
debo = true
hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health + heal
--script.Parent:Remove() --Remove the '--' at the start of the line for one use only
wait(waiting)
debo = false
end
end

script.Parent.Touched:connect(onTouch)

I think he copied it....

Guest

But, he added a script to the resources. I never really look at the script anyways xD

Let's make it more efficent, though.

Code:: script.Parent.Touched:connect(function(hit)
wait()
hit.Parent.Humanoid:takeDamage(-20)
script.Parent:Remove()
end)

Its all very good, but what if I program a brick to go over the pad containing the script, it will brake. Just at this into the script to make it a little better.
local hum = hit.Parent:findFirstChild("Humanoid")
if hum~=nil then

Code:: script.Parent.Touched:connect(function(hit)
wait()
if hit.Parent:findFirstChild("Humanoid") then
hit.Parent.Humanoid:takeDamage(-20)
script.Parent:Remove()
end
end

Code:: script.Parent.Touched:connect(function(hit)
if hit.Parent:findFirstChild("Humanoid") then
hit.Parent.Humanoid:takeDamage(-20)
script.Parent:Remove()
end
end

forgot to put ) at the end of the function
and why do you need a wait() for? its blank

ugh

Sometimes roblox would glitch this. A better way to prevent that would be to add debounce.

Expert Scripter Posts : 393 Join date : 2011-01-17

Code:: script.Parent.Touched:connect(function(hit)
local deb = false
if deb = false then
deb = true
if hit.Parent:findFirstChild("Humanoid") then
hit.Parent.Humanoid:takeDamage(-20)
script.Parent:Remove()
end
deb = false
end)

i dont know why you would need it in this case anyway, your heal pad would just be removed

Administrator Posts : 878 Join date : 2010-07-30

Ah. didn't see that. But you broke the script BTW ;)

Code:: if deb == true then

You need two ='s.

Expert Scripter Posts : 393 Join date : 2011-01-17

nooooo. oh well. we all make mistakes.

Expert Scripter Posts : 393 Join date : 2011-01-17

Code:: script.Parent.Touched:connect(function(hit)
local deb = false
if deb == false then
deb == true
if hit.Parent:findFirstChild("Humanoid") then
hit.Parent.Humanoid:takeDamage(-20)
end
wait(60)
deb = false
end)

i removed :Remove(), debounce would be useless if this wasn't done. also added wait(60)

that's better. i think.

Last I remember, local isn't needed in RBX.lua.

Expert Scripter Posts : 393 Join date : 2011-01-17

ah... but this time i have a trick. local is used for optimization (enhancing speed), it is said in lua that you should use local variables as much as possible. it saves more memory usage than using global variables. proof is in the simple script of the widely-used LinkedSword, first made by the admins of roblox. they know more about optimization than me.

Code:
script.Parent.Touched:connect(function(hit)
pcall(hit.Parent.Humanoid:takeDamage(-20)
script.Parent:Remove())
end)

Administrator Posts : 878 Join date : 2010-07-30

Well, local doesn't determine a variables *** in RBX.lua for some reason. They removed it apparently.

Expert Scripter Posts : 393 Join date : 2011-01-17

say again? oh and what is pcall()

Administrator Posts : 1081 Join date : 2010-12-09 Age : 26

pcall runs a function in protected mode so it won't crash the script if there is an error in the function.

Expert Scripter Posts : 393 Join date : 2011-01-17

how does it work? and does it limit the flexibility of the script?

Administrator Posts : 1081 Join date : 2010-12-09 Age : 26

you can not use waits in pcall or xpcall.

Novice Scripter Posts : 38 Join date : 2011-03-07 Age : 27

wait() is not blank silly :D

its 0.035009250178941

NOTE: i did not know there was a second page :P

It doesn't matter if it is RBX.Lua or Lua, local can be needed. If not needed, it is suggested. Local variables integrate themselves into the environment, making indexing them much faster.

Administrator Posts : 878 Join date : 2010-07-30

More typing = faster script

Confusing, much? Oh well, I'll start using local's again and see if I see a difference.

oysi ran a test and said that local variables were vaster than normal. ever since i've used local variables many times. XD
