I've been developing a reactor core game, and I have a temperature system used with intValue, I've tried to trigger a script for a meltdown when the temp value reaches 6500, but it doesn't trigger, what is the error I made?
if game.Workspace.Temp >= 6500 then
script.Parent.Meltdown.Disabled = false
end
I've also tried using while true do, but it didn't help.
You are probably getting error that you are trying to compare number and Instance, if [Temp] is an "IntValue", you need to get it's value by indexing it with [.Value]:
if workspace.Temp.Value >= 6500 then
script.Parent.Meltdown.Disabled = false
end
This however as you know would only check it once, you could use the while loop as you did however it's not efficient, GetPropertyChangedSignal will return a signal which will fire when property of the Instance changes.
local Meltdown = script.Parent.Meltdown
local Temp = workspace.Temp
local function OnValueChangedAsync()
if Temp.Value >= 6500 then
if Meltdown.Disabled then
Meltdown.Disabled = false
end
end
end
Temp:GetPropertyChangedSignal("Value"):Connect(OnValueChangedAsync)
I also added a check that will check if [Meltdown] is not disabled, this is not neccessary but prevents changing variable's value to same value, that would not cause an issue but yes.
game.Workspace.Temp is the userdata, which is your IntValue in this case. The problem is that you're comparing said userdata to 6500, which is a number. You should be getting an error telling you exactly this, if you bothered to look at the output of your script. IntValues have a property called Value, which refers to the value assigned to the value Instance. In the case of an IntValue, the value assigned must be a 64-bit integer no greater than 9.22e+18 and no less than 9.22e-18. (Being an integer, of course, it can't be a floating point number.)
In simple words, use the Value property of your IntValue.

It gives in the output: "attempt to call a nil value" in red.
It must be coming from other scripts you have, not from this one.
is "Disabled" the script property or a BoolValue?
Oh yeah, thank you :) it worked! Thank you very much!
