Graphics / Re: SF::Text memory access bug on draw()

« on: January 05, 2013, 11:38:39 am »

I built SFML with cmake, I think it's a couple weeks old (not sure where to find the exact build#).

I fixed (circumnavigated) the issue by making it a vector of pointers to the objects, rather than a vector of objects.  I still don't know why this would cause an issue - as you saw, the sprites drew just fine.

Also if you actually try to draw a text on top of the door rectangle, then you can't draw the text first and then the rectangle, otherwise the rectangle will cover up the text.

I realize that: the doors are supposed to cover the text.

I'll post a minimal example tomorrow, gotta hit the sack for now.

I've got a strange problem with drawing text, I made a video describing it and walking through the debugger:

EDIT:

I got it working by making my vector of doors a vector of pointers to doors.  Don't know why that was necessary, but there you go.

Thanks, it's the RC.

What exactly do you mean "alive"?

Graphics / SFML2 Textures being overridden

« on: December 29, 2012, 03:35:28 am »

Hi, I'm drawing textures and shapes on my render window, and occasionally when I draw shapes, certain textures won't show up (black box in place of the image).  I'm having trouble isolating the problem, but I'm wondering if it might have something to do with the order in which things are drawn?  Whether it's relevant or not, how does sfml decide what's in front/behind?  Is it purely the order in which they're drawn?  Thanks!

I notice it tends to happen when I set a nonzero outline on my shapes.
