Nethraz: Objects introduction + Offset tables

2016-02-22T16:26:31Z

Objects introduction + Offset tables

New page

The game uses objects to store runtime information about sprites and scripts,
e.g. size and position of a sprite, or the current script address.
Each object has a handle in range 0x1000...0x1F80, in steps of 0x40, allowing for a maximum of 63 objects.
Object data is stored in chunks of 0x1000 bytes at various places in RAM.
Objects are created by declaration in the [[Map Object Header]] or by script command.

=== Object Data ===

Offsets must be added to the object handle to get the memory address.
