What is a node struct? A node struct is used to represent an element, in our case, a brick, within a list.

An example of a structure for a node is as follows:

struct BrickNode
{
    bool Active;
    int X, Y;          // Position on screen
    int Width, Height; // Size of hitbox for brick
    BrickNode* next;   // Pointer to the next brick node
};

What is meant by malloc a node? while it is when you dynamically allocate memory create a new node in a list.

here is an example of what it could possible look like:

// Creates a new node for each brick
BrickNode* newBrick = (BrickNode*)malloc(sizeof(BrickNode));
</code?
=====LINKING NODES TOGETHER=====
Format for linking nodes together:
<code C>
newBrick->next = BrickList;

This line of code is linking the new brick node into the list. here's how it works:

newBrick

which is a node for each brick, is set to point to the current head of the list essentially putting a new node at the beginning of the list. This is done with

->next = BrickList
