Descriptive Problem Summary:
I was trying to implement a fluidic movement system but it does not seem to work out well because I think/believe that BYOND has an extra affinity to some specific direction keys.

Currently the studies shows that BYOND has special affinity for

1. the SOUTH and EAST Directions (when using the arrow keys on the Keyboard)
2. the WEST (when using the Numpad) [the diagonal keys are unbiased]


Numbered Steps to Reproduce Problem:
1.Download the Project(The Project does not contain anything related to the fluidic movement, it just shows the core problem)

2.Compile and Run, the instructions are given inside it also.

3.Using the arrow keys, hold North and South (both) at the same time.
4.Now without leaving the held buttons press East(arrow key) and observe.
[You will observe that East is considered as an input from the Player]

5.Leave all the keys and repeat step 3.
6.Now without leaving the held buttons press West(arrow key) and observe.
[You will observe that West is not considered as input from the Player when both North and South is already held whereas East is considered as an input in the same conditions]

7.Using the arrow keys, hold East and West(both) at the same time.
8.Now without leaving the held buttons press South(arrow key) and observe.
[You will observe that South is considered as an input from the Player]
9.Now without leaving the held buttons press North(arrow key) and observe.
[You will observe that North is not considered as input from the Player when both East and West is already held, whereas South is considered as an input in the same conditions]

10.Try similar steps using the Numpad keys and observe.

Expected Results:
1.Wanted the East and West keys to be considered as an input when both North and South is held.

2.Wanted the North and South keys to be considered as an input when both East and West is held.

Actual Results:
1.Only East is considered as an input.(conditions applied)
2.Only South is considered as an input.(conditions applied)
