Oh I see, can you give some examples? Thanks!
A specific example of a valid pcall that does not use a web call is
ComputeAsync(), which is used for pathfinding. An error is thrown if the navigation mesh has no vertices to reference to pathfind through.
This is the most expensive non-webcall method I’ve come across; but this isn’t surprising considering how much it is doing! Most programmers elect to limit the amount of times
ComputeAsync() is called by using raycasting or distance/position checks; never call this every frame.
Removed the part about the wording of an asynchronous name since the wording is chosen to relay what is expected when it is called.
i dont get it. How can i use it? Is it a call or fire event or naming it? why . insted of : ?
they retrieve a method that datastore (
DataStore:GetAsync() in this case) has and then pass explicit
self into that method.
pcall(DataStore.GetAsync, DataStore, "key") is same as protected
DataStore.GetAsync(DataStore, "key"), which is same as
DataStore:GetAsync("key") (and also protected aswell because its all in
you could of course use a dumbed down version and use a wrapper function provided below
local success, result = pcall(function() return DataStore:GetAsync("key") end)
or just write the result into a pre-defined local as mentioned before.
. is used instead of
: because we need to obtain a method to use
pcall on and then explicitly pass the object itself to imitate a method call.
i get it now, bassicaly it works like a module or function. But thx i already know it
