Cheat Engine

[ptvb1990]

I don't know if this is the right section for this. I need some help.

I have a pointer with a value that starts at 45 and keeps decreasing until it reaches zero.
I need a script to make a 'jump' and speed the process. Let me explain.
So, repeating.... the value starts at 45 and will then decrease. What I need is that, once it reaches 20, CE would set the value to 0.

I tried this (pretty sure the syntax is wrong)

myult = getAddressList().getMemoryRecordByDescription("MyUlt")
value1 = 20
if myult[value1] then
myult.Value = 0
end

Nothing seems to happen when i execute it. I'm using the Lua script.
I have no idea how to use this with auto assemble and compile it. If anyone could send me a beginner friendly tutorial I would appreciate it.

Please keep in mind I'm a complete beginner with cheat engine
