For each engine:
- Make a new folder detection
- Move detection-related files inside the folder
- Add a new module "enginename/detection"
- Add DETECT_OBJS here
- Adjust the normal engine module to remove detect_objs
- Adjust every file for the new changes.
Eden game object now contains a graphics object with which to
delegate graphics operations and store states of the graphics.
Much of the video playing is done in the graphics class
so I have moved a lot of the video state into there.
Some graphics related variables were moved out of eden and into
graphics, but many are still in eden.
Since they are still coupled there are lots of getters and setters.
For example both eden_graphics and eden share a handle to the same
video object.
I have made a few more things public than desirable.
I changed graphics to eden_graphics since it is specialized to eden
and not just cryo.
- Add missing default switch cases
- Specify packing for structs with pointers to complex objects
- Change literal suffixes to uppercase
- Replace uses of malloc() with new []
These occurred while compiling in Raspberry Pi Raspbian latest and
appear to be due to char being interpreted as unsigned by default,
rather than signed in two data structures. Have replaced with explicit
types to avoid this issue.
Some of the debug statements in the engine compute values or sizes of
various items by pointer subtraction (which is probably not recommended;
I am not sure if this is why some of the structs were previous packed as
noted and removed by snover).
In any case, the subtractions should result in relatively small integer
values, but using these into debug() calls with printf style format
strings can cause warnings from the compiler with the format specifier
depending on the underlying pointer sizes.
To avoid these, have recast these to int. If this does cause any issues,
they should be limited to debug() value changes and thus not a
functional issue with the engine, which can be corrected by the engine
developers.
