I did a lil map with lesson 23, and i would like to put objects into this map. These objects are display lists of a ball. I would like the ball to move back and forth (i have a goodidea how this will work) but my problem is, how do i put in a display list into lesson 23. For example, if i want a display list of the ball in front of some sector triangle in the map. How would i modify the code for this. for example, if i have a display list, GLuint BallDisplayList. The following is a cut and paste of the lesson23 drawing code. for (int loop_m = 0; loop_m < numtriangles; loop_m++) { glBindTexture(GL_TEXTURE_2D, texture[sector1.triangle[loop_m].texture]); // ( Modified ) glBegin(GL_TRIANGLES); glNormal3f( 0.0f, 0.0f, 1.0f); x_m = sector1.triangle[loop_m].vertex[0].x; y_m = sector1.triangle[loop_m].vertex[0].y; z_m = sector1.triangle[loop_m].vertex[0].z; u_m = sector1.triangle[loop_m].vertex[0].u; v_m = sector1.triangle[loop_m].vertex[0].v; glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m); x_m = sector1.triangle[loop_m].vertex[1].x; y_m = sector1.triangle[loop_m].vertex[1].y; z_m = sector1.triangle[loop_m].vertex[1].z; u_m = sector1.triangle[loop_m].vertex[1].u; v_m = sector1.triangle[loop_m].vertex[1].v; glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m); x_m = sector1.triangle[loop_m].vertex[2].x; y_m = sector1.triangle[loop_m].vertex[2].y; z_m = sector1.triangle[loop_m].vertex[2].z; u_m = sector1.triangle[loop_m].vertex[2].u; v_m = sector1.triangle[loop_m].vertex[2].v; glTexCoord2f(u_m,v_m); glVertex3f(x_m,y_m,z_m); glEnd(); } How can i print the display list of the ball in the above drawing code? Or is there an easier way to do this? -NPC
