<p>
|

|
|
overlay.pic does the same thing as <a href="draw_pic.html">draw.pic</a>, except that the visual and priority screens are not cleared. This means that picture vA is drawn on top of the existing picture. Note that
|
||
|
|
because fills only work on white surfaces, fills in picture vA which are not on a white part of the existing picture wont work. It's generally best not to use fills in pictures that you intend to
|
||
|
|
overlay.
|
||
|
|
<p>
|
||
|
|
Remember to use <a href="show_pic.html">show.pic</a> to update the screen once the picture has been overlayed.<p>
|
||
|
|
Make sure the picture is loaded into memory before overlaying it.<p>
