RecastNavigationDelphi

Port of Recast Navigation into Delphi

Source code location: https://github.com/memononen/recastnavigation

Source code version: Around 01 Nov 2014

Porting guidelines:

RecastNavigationDelphi is a straight clone of RecastNavigation with as little changes as possible, to allow to keep projects synced in the future.
Any changes/improvements to the lib functionality should be first included into C++ master to avoid separation.
RND follows RN structure very closely, except for GUI stuff, which is VCL for simplicity instead of imGUI RN solution.
All file names are the same, but with an "RN_" prefix.
Some units were split to avoid circular dependencies, they are called RN_UnitNameHelper.

Hints about the code:

Multi-condition "for" loops and loops where iterator gets changed inside the loop, were converted to while/repeat loops. Loop code needs to be repeated before any "continue".
Move method first two arguments (Src, Dst) need to be swapped in Delphi.
Delphi needs to wrap overflowing manipulations with a {$O} directive to supress errors.
Delphi needs manual disposal of objects created within record , as they dont have built-in destructor support in them.
To simplify the pointer trickery, {$POINTERMATH ON} had to be enabled almost in every unit.
Typed @ operator setting is great help, but sadly it does not work sometimes.

Common pitfalls during porting:

Passing argument @SomePointer instead of SomePointer. Typed @ helps to catch those, but not always.
Calling Move/FillChar methods without swapping arguments places.
Writing for .. to .. do loop instead of for .. downto .. do in rare cases.
