Notion of pivot point now for rotating, i.e. the anchor point at which
rotations are applied. Rotating the reticule is done by using inverse
trigonometry, namely atan2f.
Mobs battle in real-time with the hero when in range. Start encapsulating
logic into entityStateSwitch() to organise entity properties changing
between different states.
Introduce basic concept of memory management in MemoryArena. Begin passing
around a memory object to track memory usage and eventually delegate
memory allocations through. Remove the old memory tracker in the debug
object and incorporate into engine primarily.
Add a debug console for logging information and events to the screen in
a console-like fashion. Debug is now initialised after the game, this is
so that you can pass the game's memory arena and font file to the debug
services. Debug services now properly initialise debug element positions
from this information and not through the update routine.
The main debug drawing elements have been moved to debug.c to avoid
cluttering up the main game file. The downside is that thus far the debug
values only track values post-update.
We have a notion of begin attack and end attack to allow code to drive the
animation system and apply effects after an attack animation has
completed.
Separate notion of rendering a static string, i.e. for debug display that
is absolutely positioned, and rendering of a regular string that moves
with the game camera.
