Intermediate C++ Game Programming Tutorial 6
From Chilipedia
This tutorial is epoch-making, DO NOT SKIP IT. The ostensive main topic for this video is destructors, but that is not where its soul lies. After learning about dtors, we are ready to discuss a matter that is at the heart of C++: RAII. This will form the bridge between low-level memory management, and high level smart objects. We also discuss the important concept of deep copying and the Rule of 3, and related to this, we review the 4 original special member functions. AND there are discussion of a bunch of other random bullshit, like converting construction for example. It's a big video is what I'm tryin' to say here.
Topics Covered
- RAII (Resource Allocation Is Initialization)
- Deep Copy vs. Shallow Copy
- Rule of 3 / Rule of 0
- Destructors
- Special Member Functions
- Converting Constructors
-
explicitKeyword for Constructors - Copy Construction with Assignment operator
= - Constructing with
()vs. with{} - Deleting Special Member Functions with
= delete - Conditions when Special Members Cannot be Generated by Compiler
