Actually is it good to work constantly with decimals in general? or is it better to work with math.floor or math.ceiling? (although they are slow to...) thank god that bar...

Re: Code Optimizing & Performance trics

There is no way when this happens exactly unless you call the garbage collector explicitly, and even then you can only be sure it is collected afterwards , the GC just collects whenever it detects your program is not doing anything time-critical. so it's not like that the collector is run automatic...

Re: Code Optimizing & Performance trics

Some questions If you have a loop running through a table. for i, item in pairs( itemtable ) do if condition = true then itemtable[i] = nil end end So this should make some items in the table nil. - I heard the garbage collector picks them out and removes them from the table at some point? is this c...

do you mean loop through a table using pairs or table?

Things you should bear in mind when making your game a fast as possible. Like how to handle variables, loops, tables, garbage collection... These are things I've fo...

Re: what is this code doing?

wel self.button is actually a metatable existing out of keys and values n = key and b = value (this example a button) the code itself is a for loop, iterating through every key of the table (in this example every button added to the table) b:update(dt) <-- this will update the button Someone correct...
