intbuffer.put problem

[pandur]

Hi,

i had some troubles using gldrawbuffers, but it works now.

but please can enlighten me what is wrong?

this works:

IntBuffer ib=BufferUtils.createIntBuffer(2);
ib.put(0, EXTFramebufferObject.GL_COLOR_ATTACHMENT0_EXT);
ib.put(1, EXTFramebufferObject.GL_COLOR_ATTACHMENT1_EXT);
GL20.glDrawBuffers(ib);

   
this does not work:

GL20.glDrawBuffers(BufferUtils.createIntBuffer(2).put(new int[]{EXTFramebufferObject.GL_COLOR_ATTACHMENT0_EXT,	EXTFramebufferObject.GL_COLOR_ATTACHMENT1_EXT}));

i think it should give the same result...

thanks

the latter doesn't work, because the put moves the internal pointer in the buffer. You need to call rewind on it.
