Replacing the background image is actually a lot more complex than you might imagine. Once you use the
|
||
below code, it can be done without any problem. But you need to do it this way, or it just goofs up in
|
||
a number of small ways.
|
||
You need to tell the sprite controller that you are replacing the background image,
|
||
and you need to change the image to that image as well.Because the Images are actually
|
||
pointers to memory where the image sets, changes to one image will affect the other image.This goofs
|
||
things up, so what we do is duplicate the image twice, and tell the sprite controller to use one of the
|
||
copies and then set the background to be the other one of the two copies.Finally, we tell the picturebox
|
||
to invalidate itself.That does everything that is needed.
