Change object perspective?

[matredman]

To solve a puzzle my character must use different posters(objects) with a series of walls. The right combination sort of thing.

Anyhows, the walls are at different angles. So what the character needs to be able to do is try different posters with different wall spaces so he can see it. And each time a poster is used on a different wall, the character puts it up and so forth. I need to have the posters alter their perspective to suit each wall space.

The only solution I can think of is to re-draw the walls as flat/straight and have a universal perspective for the objects.

Or you could draw the posters as if they were on each wall, have an object on each wall where the poster should be, and use:
ObjectOn(x);
SetObjectGraphic(x, y);
when the player uses a poster on a wall.
x = wall object number
y = sprite number for poster used on wall x

Ahh! Thankyou for the insta-help earlier-it seemed working well, but now its gone glitchy on me.

One thing, it wont recognise the sprites I tell it to(I've made the correct angle sprites to correlate with wall perspective). It keeps using the wrong image. And I've tried changing the sprite number and even lined them up in a row but it just won't listen.
Another issue is being able to pick up the object again after its been applied.
