General / Make some sfml objects as static

« on: December 01, 2010, 12:31:38 am »

Always post error messages, "i get some erros" is not very helpful.
I'm assuming you're getting linker errors.
I think you want something like this:

Code: [Select]


//GameObjects.hpp
class GameObjects
{

private:
  static sf::RenderWindow myApp;
};
//GameObjects.cpp
sf::RenderWindow GameObjects::myApp(sf::VideoMode(800, 600, 32), "SFML Graphics");

Graphics / C++ writing out pictures from an array

:chuckles:
I can see how he could get confused though.
I always though sf::String should be sf::Text or something so it wouldn't be confused with a std::string like object.

Anyways, I believe what you're looking for Jamie is sf::String, not std::string.

I just thought I'd add another alternative in case anyone needs one:

General / 1st Demo Using SFML - Only Get Console Window - HELP

Oh yeah. I wasn't very awake when I wrote all that...

Window / Re: Multiple keys pressed

« on: January 21, 2009, 01:18:53 pm »

Post more of the code if you can.
If I had to guess I'd say you're making a simple logic mistake.
Step through with a debugger if you can.

I don't see anything really wrong with your code.
Although, I'm not sure this is doing what you think it is:

Code: [Select]


     // Start the game loop
     while (App.IsOpened())


See here
I think IsOpened will only return false when the window has not been created.
I would recommend something like this:

Code: [Select]


bool Done = false;
while (!Done)
{
    //Render...
}


Code: [Select]

This is what concerns me.
I've never seen these auto-import messages.
I'm wondering if you're using SFML DLLs and not defining SFML_DYNAMIC.
Is that it?

Graphics / Image::CopyScreen

Ah I see it.
Seems like it wasn't there last time I checked.
Oh well.

Graphics / Image::CopyScreen

« on: January 12, 2009, 06:56:56 pm »

Image::CopyScreen appears to still be flipped in SFML 1.4.

I only tested by saving to a png.

I'm using RenderWindow::Capture now instead.

Graphics / Image::Copy

« on: January 03, 2009, 10:41:20 pm »

I can't seem to produce a working example outside of some sfttf code.

I'll have to investigate it a little more.
I'm tired of it today, so maybe tomorrow.

Graphics / Image::Copy

« on: January 03, 2009, 04:36:11 pm »

Using sf::Image::Copy (or LoadFromPixels w/GetPixelsPtr) I keep getting a single white pixel in the bottom-right corner of the destination image.

Code: [Select]


sf::Image sourceImage;
... (load image, etc)
sf::Image destImage;
destImage.Create(sourceImage.GetWidth(), sourceImage.GetHeight());
destImage.Copy(sourceImage, 0, 0);

So here destImage would look just like sourceImage, except it would have a white pixel in the bottom-right corner.

This doesn't seem to happen every time, but often it does.
I'm using the latest SVN.
I can post more info later if needed.

SFML projects / sfttf - truetype scalable fonts in SFML

« on: January 02, 2009, 11:35:46 pm »

They are drawn separately.
The filled layer is drawn on the bottom, the outline on top.

What if you reverse the order?

You'd get pretty much the same results, I already tested it.

How is it drawn on screen? is the fill color and outline color drawn at the same time or are they like separate "layers"?

I don't know much of this nor the terms used

They are drawn separately.
The filled layer is drawn on the bottom, the outline on top.

I'm thinking maybe I can use the filled character to create the outline character and xor it so it is only on the 'outside'.

SFML projects / sfttf - truetype scalable fonts in SFML

« on: January 02, 2009, 03:24:59 pm »

It's looking like outlines need a minimum size of around 30-34 with the fonts I tested.
The ftview freetype demo program is the same way.

I don't think there's really an easy way around this.

It seems the outline is rendered more in the 'middle' than the outside.

SFML projects / sfttf - truetype scalable fonts in SFML

« on: January 02, 2009, 02:04:42 pm »

Thanks a lot!

However in order to compile the source I had to do the following:

Move this to Glyph.hpp from Glyph.cpp:

Code: [Select]

#include <SFML/Graphics/RenderWindow.hpp>

Thanks, not sure why my compiler didn't complain about that.  :oops:

...and change row 301 in Font.cpp from:

Code: [Select]

if (0 != FT_Stroker_New(myFreeType, &myStroker))
to:

Code: [Select]

if (0 != FT_Stroker_New(reinterpret_cast<FT_Memory>(myFreeType), &myStroker))

Sorry! I forgot about this!
I posted a feature request here:
http://www.sfml-dev.org/forum/viewtopic.php?t=841
I'm using a newer version of FreeType.
I'll switch it back to the older version and add the reinterpret_cast.

This also made me realize I wasn't calling FT_Stroker_Done too.
So thanks!

Also, is the outline drawn on the inside of the character? because using small font sizes the only thing you can see is the outline color. I tried using font size 20 and outline size 1 and the only thing I could see was the white outline.

Yes, this could be a problem.
This is something I'll be looking into.
I'm not really sure how to do this right now.
The whole stroker/outline API in FreeType is a bit confusing to me unfortunately.
