Screen Shake Modified To Work With View Following Player
in my original code I set view[0] to be shifted around by the value of the calculated variable ‘xp’.   If you have a view following the player then you have to set the position of the view so that the player will be centered in the view and then apply this shift of ‘xp’.   You could modify the line

view_xview[0] = xp      and change it to
view_xview[0] = oPlayer.x – view_wview[0]/2.0 + xp

Do similar to y axis but use   view-hview[0]/2.0 + yp.  Assuming player object is called oPlayer.  Note this will only work when the player object exists so you should do a quick check before to make sure it does…
