I wanted to make a mirror effect and that's what I did:
1) I made a fully white image using a paint programme ,then saved it as .pcx
2) I put the sprite in the level using WED ,then attached it to an action
3) In the code, before the sprite action, I defined a view with with pos_x ,pos_y = 0 and size_x ,size_y equal the same size of the sprite that is smaller than that of the screen resolution and with SHOW and CULL_CW flag set
4) In the action attached to the sprite, I set its pan angle to 360 to be oriented, then set x, y, z, pan, tilt and roll of the view equal to those of the sprite (my). After that, I added that line
mirror_view.bmap = bmap_for_entity(my,0);
The problem is that the view is rendered over the screen instead of the sprite texture bitmap
Thank you for reading and any help will be appreciated

Have you compared your work to the unanswered question in AUM 94? bmap_for_entity() might be returning NULL;

I don't want to disappoint you ,but the problem still exists. The view is rendered over the screen instead of being rendered over the sprite Here's my code:
VIEW* mirror_view;
ENTITY* mirror_sprite;
function startup_mirror()
{
mirror_view = view_create(10);
wait(2);
mirror_view.size_x = 192;
mirror_view.size_y = 230;
set(mirror_view,SHOW);
mirror_view.bmap = bmap_for_entity(my,0);
mirror_view.x = my.x;
mirror_view.y = my.y;
mirror_view.z = my.z;
mirror_view.pan = my.pan;
mirror_view.tilt = my.tilt;
mirror_view.roll = my.roll;
}
action mirror_act()
{
mirror_sprite = my;
set(my,PASSABLE | DECAL);
startup_mirror();
}
Peace!

Works just like it should... Um your code doesn't but the AUM 94 code does... Look up _startup in functions.
VIEW* mirror_view;
ENTITY* mirror_sprite;
function mirror_startup()
{
while(!mirror_sprite)
wait(1);
mirror_view = view_create(10);
wait(2);
set(mirror_view,SHOW);
mirror_view.size_x = 192;
mirror_view.size_y = 230;
mirror_view.bmap = bmap_for_entity(mirror_sprite,0);
mirror_view.x =mirror_sprite.x;
mirror_view.y = mirror_sprite.y;
mirror_view.z = mirror_sprite.z;
mirror_view.pan = mirror_sprite.pan;
mirror_view.tilt = mirror_sprite.tilt;
mirror_view.roll = mirror_sprite.roll;
}
action mirror_act()
{
mirror_sprite = my;
set(my,PASSABLE | DECAL);
}
It is clear by your problem and the AUM code that passing the my-pointer is getting you a NULL return by bmap_for_entity. It is also possible that the my-pointer is being set to the newly created view, but I'm not going to test to find out as the code above is working.

If you used the exact code from above and had a problem. Then check the file format of the sprite. Possibly try changing it to a windows bitmap .bmp in 24-bit mode.. It is not possible that this code runs on my system and not yours, if there was an error in the code. The code is fine, so your error could be machine or file format. Also make sure you have the latest version of the engine but this is most likely not the problem.

Sorry but the code I post above is working perfectly. And it is not a file format issue. I can tell to do this....
/// the mirror code ends here
while(1)
{
DEBUG_VAR(mirror_view.bmap,10);
DEBUG_VAR(bmap_for_entity(mirror_sprite),20);
wait(1);
}
If the first debug is 0 or not matching the second debug or both are 0. Then bmap_for_entity() is failing. This can happen if you leave out -
while(!mirror_sprite){wait(1);}
- I don't know the free versions limits, so can't give you any more help with this. Sorry Mal

You not wasting my time. I simple don't know what more to tell you. It could be your graphics card or it could be the engine version. If no one else can answer in 24 hours you might try asking in the "Ask the developers" section, but before you do see if you can find a list of the feature for the Free version to rule that out. Also 'if you can' download the trail version of the full engine and test the code. If the problem still exist with the full engine then you can rule-out engine version as the source. The code is fine George doesn't publish broken code and I wouldn't lie about my test results. So maybe it's a bug or graphics card problem.
I wish you luck and I sorry I didn't have a solution for your problem.
