Here''s the code: //global GLuint laser; // GLvoid BuildList() { laser=glGenLists(1); glNewList(laser,GL_COMPILE); glLineWidth(1); glColor3f(1.0f,0.0f,0.0f); glBindTexture(GL_TEXTURE_2D, texture[4]); glBegin(GL_LINES); glVertex3f(0.0f,0.0f,0.0f); glVertex3f(0.0f,0.25f,0.0f); glEnd(); glEndList(); } void lasers(){ glLoadIdentity(); glTranslatef(rightlaserx,rightlasery,yourshipz); glCallList(laser); } int DrawGLScene(GLvoid) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); lasers(); return TRUE; } The laser doesn''t show up. Any ideas? Thanks!

Hmm, no, that''s not the problem. It works fine when I take away the display list and just have this:

glLoadIdentity();
glTranslatef(rightlaserx,rightlasery,yourshipz);
glLineWidth(1);
glColor3f(1.0f,0.0f,0.0f);
glBindTexture(GL_TEXTURE_2D, texture[4]);
glBegin(GL_LINES);
glVertex3f(0.0f,0.0f,0.0f);
glVertex3f(0.0f,0.25f,0.0f);
glEnd();
