java - LWJGL random lines inbenween shapes

Question

I have random lines inbetween my quads in my game which I would like to remove:

as you can see, there appear to be lines inbetween the cubes. Does anyone know how to remove them? I am using openGL.

Edit: What I mean is is there any OpenGL functions such as glEnable to fix this?

Answer 1

I'm guessing you have all of your textures on on image?

Near the edge of the block, OpenGL is sampling nearby pixels to make it smooth, so on the edge of your dirt block you can see it slightly fading into a stone block

try the lwjgl version of this:

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST) glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST)

(the above is in in c++)

This will give you the pixelated effect like minecraft
