hello, I am attempting to render lines in a GUI. This will not be possible to achieve with textures. I have attempted to use the methods documented in this for unbatched environments but the methods do not seem to exist this is the documentation https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e.

I further tried to do this using GL11. I have successfully rendered a line but I was unable to change the colour of the line.

This is what I tried in the render method:

GL11.glPushMatrix();
        GL11.glPushAttrib(GL11.GL_COLOR_MATERIAL);
        GL11.glEnable(GL11.GL_BLEND);
        GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);
        GL11.glLineWidth(6.0f);
        GL11.glColor3ub((byte)255,(byte)0,(byte)0);
        GL11.glBegin(GL11.GL_LINES);
        GL11.glVertex3d(1, 1, 0);
        GL11.glVertex3d(100, 100, 0);
        GL11.glEnd();
        GL11.glPopMatrix();
        GL11.glPopAttrib();

Having messed with this in the past:

1) Do not use GL11 directly, use the wrappers

2) GL11.GL_LINES does not work the way you want or expect (I don't know why and don't care).

Thanks, I will experiment with other GL modes. I resorted to using GL11 directly because I did not even manage to render it with the wrapper.

Edit: And the line strip works. now to just get it working with the wrappers
