[ARRAY] - Moving all values to the left

Ok so I got a 1D array which looks like this

[ ][ ][ ][N]

For every X seconds I want the N to move one to the left and when it comes "off" the edge it is gone from the array.

So it would look like this:

[ ][ ][ ][N]

[ ][ ][N][ ]

[ ][N][ ][ ]

[N][ ][ ][ ]

[ ][ ][ ][ ]

[ ][ ][ ][ ]...

Anyone got an idea on how to do this? I would be very happy for any help.

Set each value in the array to the value to the right.

Array: For each X element:

---- Array: set value at self.CurX to self.At(self.CurX+1)

Thank you! I will test this out.

Anyone that knows why this won't work? Did try R0J0hound's example but it won't work either.

(It is in sub-events while I am debugging)

*It got fixed by removing all the inverted conditions*
