Graphics / Re: Converting from world to screen coordinates

« on: September 20, 2012, 08:53:15 pm »

Damn, I was trying to avoid having to do that, but I guess there is no other choice.

Maybe I can get it to work with sf::RenderWindow::convertCoords()...from my understanding, it converts mouse coordinates to world coordinates by passing in your world view...so if I pass in a view with a view made from the inverse of the world view, it should convert world coordinates to screen coordinates...

maybe.

e: that convertCoords() idea I had definitely didn't work.

Graphics / Converting from world to screen coordinates

« on: September 20, 2012, 01:15:04 am »

I am using a view to zoom + translate a tile map and it works fine. The problem is, I have light position's in world coordinates and am using a light attenuation shader to draw the light - I need to convert the light's position in world coordinates to screen coordinates. I have tried using view.getInverseTransform().transformPoint but it gives odd results.
