VBOs not working for no reason I can see

[poo2thegeek]

Quite simple, I'm trying to draw some stuff with a vbo. Here is the code that creates the vbos:

sides_[ABOVE][0] = glGenBuffers();
		sides_[ABOVE][1] = glGenBuffers();

		float[] top_ = {-r,r,r,    r,r,r,     r,r,-r,    -r,r,-r};
		float[] toptex_ = {0,0,    64*pix,0,    64*pix,1,    0,1};
		
		FloatBuffer top_buff = BufferTools.asFlippedFloatBuffer(top_);
		FloatBuffer toptext_buff = BufferTools.asFlippedFloatBuffer(toptex_);
		System.out.println(sides_[0][1]);
		glEnableClientState(GL_VERTEX_ARRAY);
		glEnableClientState(GL_TEXTURE_COORD_ARRAY);
		
		glBindBuffer(GL_ARRAY_BUFFER,sides_[0][0]);
		glBufferData(GL_ARRAY_BUFFER,top_buff,GL_STATIC_DRAW);
		glBindBuffer(GL_ARRAY_BUFFER,0);

		glBindBuffer(GL_ARRAY_BUFFER,sides_[ABOVE][1]);
		glBufferData(GL_ARRAY_BUFFER,toptext_buff,GL_STATIC_DRAW);
		glBindBuffer(GL_ARRAY_BUFFER,0);

The 'BufferTools.asFlippedFloatBuffer(..);' leads to this method:

public static FloatBuffer asFlippedFloatBuffer(float... values) {
        FloatBuffer buffer = BufferUtils.createFloatBuffer(values.length);
        buffer.put(values);
        buffer.flip();
        return buffer;
    }

All of this should work as far as I can see.
I then draw the vbos at a later date in this method:

glBindBuffer(GL_ARRAY_BUFFER,sides_[0][0]);
		glVertexPointer(3,GL_FLOAT,0,0);
		glBindBuffer(GL_ARRAY_BUFFER,sides_[0][1]);
		glTexCoordPointer(2, GL_FLOAT, 0, 0);
		glEnableClientState(GL_VERTEX_ARRAY);
		glEnableClientState(GL_TEXTURE_COORD_ARRAY);
		glDrawArrays(GL_QUADS,0,3);

This should work, but for some reason it doesn't. Any help is useful!
Thanks in advance.

Well the final call you make is glDrawArrays(GL_QUADS, 0, 3); When I was in school (and that is right now) there were 4 vertices in a quad.

The thing with VBOs is that there are so many stupid mistakes to make, that when you make one you always manage to consistently miss it.

Damn... I always thought that the final parameter was similar to that used in glVertexPointer, where the number is the amount of floats for each bit.
Thanks very much!!!!

Glad to help. And as it turns out I actually taught you something new. Great.
