Quick question, how do you properly texture a GL_QUAD_STRIP glBegin(GL_QUAD_STRIP) ; glTexCoord2f(0.0f, 1.0f) ; glVertex3f(xPos, yPos, zPos) ; glTexCoord2f(1.0f, 1.0f) ; glVertex3f((xPos + playerW), yPos, zPos) ; glTexCoord2f(1.0f, 0.0f) ; glTexCoord2f(1.0f, 1.0f) ; glVertex3f((xPos + playerW), (yPos - playerH), zPos) ; glTexCoord2f(0.0f, 0.0f) ; glTexCoord2f(0.0f, 1.0f) ; glVertex3f(xPos, (yPos - playerH), zPos) ; glTexCoord2f(0.0f, 0.0f) ; glTexCoord2f(0.0f, 1.0f) ; glVertex3f(xPos, (yPos - playerH), (zPos - playerD)) ; glTexCoord2f(1.0f, 0.0f) ; glTexCoord2f(1.0f, 1.0f) ; glVertex3f((xPos + playerW), (yPos - playerH), (zPos - playerD)) ; glTexCoord2f(0.0f, 0.0f) ; glTexCoord2f(0.0f, 1.0f) ; glVertex3f (xPos, yPos, (zPos - playerD)) ; glTexCoord2f(1.0f, 0.0f) ; glTexCoord2f(1.0f, 1.0f) ; glVertex3f((xPos + playerW), yPos, (zPos - playerD)) ; glTexCoord2f(0.0f, 0.0f) ; glTexCoord2f(0.0f, 1.0f) ; glVertex3f(xPos, yPos, zPos) ; glTexCoord2f(1.0f, 0.0f) ; glTexCoord2f(1.0f, 1.0f) ; glVertex3f((xPos + playerW), yPos, zPos) ; glEnd() ; As above, i tried to specify to texcoords for each vertex, but that didn''t really tetxure it properly (the texture kind of flickers and move''s when the polygons change position). It''s probably a simple fix (i hope , but i don''t know it. Any help would be great. Thanks. MelvinElvin

Um... why are you calling the glTexCoord2f() function twice before drawing each vertex?

You''re supposed to go something like:

glTexCoord2f(0,0); glVertex3f(0,0,0);
glTexCoord2f(1,0); glVertex3f(1,0,0);
glTexCoord2f(1,1); glVertex3f(1,1,0);
glTexCoord2f(0,1); glVertex3f(0,1,0);

thanks wavarian, but it''s in a strip, so in the code the 2 specified vertices match up with the last two to draw the quad. Therefore, when i specify each vertex it will have to tex coords, one for the first quad it connects with and one for the other..... that''s why i''ve got 2 texcoords per vertex.

unless i''m missing something.

thanks anyway, MelvinElvin

First things first,

You only need to specify 1 texture coordinate per vertex. A single vertex cannot have two different texture coordinates associated with it.

With that said what you need to do is use texture coordinates greater than 0 and 1, such as 2,3,4,5...etc.

Imagine 4 square quads in a strip like this:

####

now for the first quad the texture coordinates will be:

bottom left (0,0)
top left (0,1)
top right (1,1)
bottom right (1,0)

for the second quad the texture coordinates will be:

bottom left (1,0)
top left (1,1)
top right (2,1)
bottom right (2,0)


for the third quad the texture coordinates will be:

bottom left (2,0)
top left (2,1)
top right (3,1)
bottom right (3,0)



and etc...


Draw this out on a piece of paper and itll make sense. (I hope) =)

You''re correct for this situation, but with multitexturing you can have more than one texture coordinate per vertex .

Bah, picky picky! =)

Yes in the case of multitexturing you could have more than one texture coordinate per vertex.

Yeah, I agree . If I didn''t say it, someone else would though, heh.
