Level Data (Objects) |
Super Mario Bros. 1 |
A buffer for rendering horizontally extendable objects. The buffer is represented as a stack that starts at $7E1304 and ends at $7E1300. A value of #$FF means there is no object to render. A value greater than or equal to zero means this object should render at the current X-coordinate.
Each byte represents the remaining width of the object to render. The area data parser renders the level an X-coordinate at a time. The renderer pauses until the player moves forward and more tile data needs to be read (this strategy to load area data is why you can't scroll backwards in SMB1).
How the buffer works is, when an object is at the X-coordinate as the area data renderer (the coordinate it is currently rendering) it will do the render logic for that coordinate, decrement the buffer value, and move on. Once the buffer value gets to $FF, this buffer value is free to use for another object. It will save the 16-bit index of this object relative to the area data address at $7E1305,x, and the 8-bit width of the object at $7E1300,x.
If there is already an object at the current buffer stack, the object will be saved to the next buffer location. If all five buffers are filled, the render will not render anymore objects until it gets to the next screen and the buffer is reset. This places a limit of 5 objects per X-coordinate in SMB1. |

$7E1305
|
10 bytes |
Level Data (Objects) |
Super Mario Bros. 1 |
A buffer that saves the index of the area data object in the respective buffer of $7E1300.
Once an object is ready to be rendered at its X-coordinate, the width of the object is saved to $7E1300,x and the index of this object in the area object data is saved at $7E1305,x. The X register for $7E1300,x is 8-bit, but for $7E1305,x it's 16-bit. |
|
$7E130F
|
5 bytes |
Level Data (Objects) |
Super Mario Bros. 1 |
A flag for the current buffer object at $7E1300. If that object is a green tree platform, then this flag is set when it's rendering the left base of the tree (the stem), and then cleared once it reaches the right base.
This flag is used to determine when to start and stop rendering the stem green tree platform. |
|
$7E1314
|
5 bytes |
Level Data (Objects) |
Super Mario Bros. 1 |
A value used for the current buffer object at $7E1300,x.
If that object is an orange mushroom platform, then this value is set to half the width of the platform and is used to determine where to draw the stem of the mushroom. |
