metatable question

[dawn zephyr]

i was planning on getting into metatables but i wanted to ask: can i make it fire a function whenever a specific value in the table is changed? and how would i write this?

[agile bison]

Yes, __newindex is good for this

that just detects new indexes tho

suspicious link🥶

[manic sail]

you would want to do a proxy table

[agile bison]

You can make it update and detect any accesses as shown in the second link

dw i can just check the documentation

[agile bison]

Lua’s official website btw

what suspicious it's literally the documentation of the language

[dawn zephyr]

no embed = suspicious🗣️

[agile bison]

[dawn zephyr]

[agile bison]

I'd not recommend you do this if you need to calculate/cache a result or especially if you yield there
Just make a get method like getSmth/getSmthAsync
This way you for sure won't mess up inheritance and will make it more readable and you will be able to pass arguments to the function

And it's just a more common approach in general

[keen bane]

proxy table is rarely seen

newproxy?
