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
