Making a shape with textures, how?
« on: April 04, 2011, 11:39:26 am »
Hi

I want to make a sf::Shape that can have like 4 different textures.. After a bit of research I realized that couldn't be done straight out of the box.

So I was thinking of doing like I did when I made my DBPro map edtior.
Have 4 textuers and a shader. Then the polygon is painted with four different colors. Each colors represents a texture.

ex:
255, 000, 000 - Grass
000, 255, 000 - Stone
000, 000, 255 - Blood
255, 255, 255 - Gravel

Then the shader would do its magic. But as far is I know this neither is doable with SFML because it only takes whole-fcking-screen shaders, right?

Sooo.. any help?

SFML 2 has shaders that can be applied to individual drawables.

Okey, two questions then..

1. How do I compile SFML 2?

2. How can I add my own classes?
At the moment I'm using version 1.6 and tried to add my own class, but when I recompiled it, it still didn't show up..


Edit..

Don't know who or what cmake is, but it seems to fail cause of a user-input. >_>

To SFML? Why would you do that?

You must install FreeType ;)
And all other libraries SFML depends on, if you don't have them.

You must install libglew and libsndfile.

By the way, when you install libxxx-dev you automatically get libxxx, no need to install it manually.

You must install libxrandr.

By the way, the list is in the tutorial

Did you compile SFML statically (BUILD_SHARE_LIBS=FALSE)?

I was not telling you to do so, I was just waiting for an answer, and eventually tell you *not* to build SFML statically under Linux.

Did you install libxrandr-dev?

Oh, my mistake. Yes, I've installed libxrandr-dev and just changed back the libs.

Okey, tried to include /usr/include/X11 - didnt work, then I tried /usr/include/ which didnt work netiher.. Tried to reinstall some packages. Rebooted.

Still not working.

Edit: Don't know what I just did; but now Im getting
