Hallo!
I have the following (basic) GEM problem (and some ascii-art ;) :
I have 2 movies running with pix_film which are rendered on rectangles
with the same size over the whole screen and I want to see only a part
of each movie (see illustration):
from movie A:
-------------------------------
| |
| |
| |
| |-------| |
| | partA | |
| | | |
| |-------| |
-------------------------------
from movie B:
-------------------------------
| |--------| |
| | partB | |
| | | |
| |--------| |
| |
| |
| |
-------------------------------
together:
-------------------------------
| |--------| |
| | partB | |
| |(movieB)| |
| |-------| |--------| |
| | partA | |
| |(movieA| |
| |-------| |
-------------------------------
So I tried to lay black rectangles over the movies and let free
partA,partB so that one can only see these parts. But this does not work
for multiple movies, because then I only see the movie with the highest
gemhead priority (and also with alpha blending it was not possible) ...
So my question: is this possible without additional pix_* commands ?
(e.g. texturing only a part of the movie onto a rectangle ... ?)
If yes has someone an idea how ?
Thanks for any hint,
LG
Georg
PS: if this is too confusing I can send an example patch ;)
