* Refactor GetRotaryDistance to use Point instead of int x/y params
* Refactor HSExists to use Point instead of int x/y params
* Refactor IsPathBlocked to take typed params (Point, Direction)
The caller was already passing in a Direction value so this matches usage better. I also pulled the Direction to Point helper function up so it is available as a static class member, this allows replacing the use of the Offset array in plrctrls.cpp.
When adding a Direction to a point (and not scaling it first) I avoid explicitly creating a Point object since the operator+ overload will do that conversion implicitly.
* Replace Offsets array with Point::fromDirection
* Refactor GetDistanceRanged to use Point
I've added ExactDistance as a member function of Point to match ApproxDistance instead of only having it defined in GetDistanceRanged, it seemed more appropriate to be part of the class. Also removed temporary variables from callers of GetDistanceRanged as they were mainly used as a convenience for avoiding repetition when passing values into this function.
* Refactor GetDistance to use Point
This mostly change player to be by reference instead of by index.
But additionally it does stript checks for gold in the belt, move some
value types to the initialization and short circute a few functiongs.
- controller: Move inventory coordinates logic to outside of the method to ease visibility and changes; Fix cursor offset when holding items on the inventory; Move cursor between edges of the inventory to ease movement inside.
- Renamed InvGetCoord to InvGetSlotCoord.
- adding more SLOTXY_xxx options to improve controls code
- changed inventory slots comment to improve legibility
- fixing bugs and centering sprite on the slot
- fix belt item movement
- slots 9 and 10 move to belt 8 when moving down using a controller
- creating function to return correct mousePos slot to remove code duplication
- create BeltGetSlotCoord to get coords for belts and remove duplicates; code cleanup.
- adding INV_ROW_SLOT_SIZE to hold the amount of slots on an inv row
- improve code for moving item to the belt when it's the last 2 slots.
- fix bug that would not update the cursor position when going up on certain conditions.
- equip equipment when pressing [use] on the controller
- moving items in the inventory as a single instance, and blocking them from moving accordingly.
- move item to belt when clicking the spell button (Y)
- resetting the cursor takes into consideration if the current slot has an item that is bigger than 1x1
- change whitespace to tabs on inv.h changes
- fixing plrctrls.cpp formatting
