Diagonal walking on special zone

[MEHRDAD]

Hi

I have a character with 32X32 pixel and moving is with mouse point and click.I haven't problem with left,right,up and down.But for diagonal move i can't write exactly code for a special zone.

code for Up-right:
X"Character" < X"destination mouse"
Y"Character" > Y"destination mouse"

But i want when player click on a special zone , character move diagonal to Up-right.This is special zone:
Please draw a diagonal line (for instance 45 degree ) from character head to Up- right and draw another diagonal line from bottom character to up-right.my zone is between this two lines.how can i optimize codes or any formula?
Appreciate for any help

Edit : As my character is 32X32 i think two lines are Y = X + 16 and Y = X - 16
