well I am working on a simpler game called tic tac toe, my question is how do I get the mouse click to draw an X on the board. when I click the mouse nothing happens. #include <freeglut.h> #include <iostream> using namespace std; void drawBoard() { glPushMatrix(); glColor3f(1.0f, 0.0f, 0.0f); glBegin(GL_LINE_STRIP); glVertex3f(-18.75f, 6.25f, 0.0f); glVertex3f(18.75f, 6.25f, 0.0f); glEnd(); glBegin(GL_LINE_STRIP); glVertex3f(-18.75f, -6.25f, 0.0f); glVertex3f(18.75f, -6.25f, 0.0f); glEnd(); glBegin(GL_LINE_STRIP); glVertex3f(-6.25f, 18.75f, 0.0f); glVertex3f(-6.25f, -18.75f, 0.0f); glEnd(); glBegin(GL_LINE_STRIP); glVertex3f(6.25f, 18.75f, 0.0f); glVertex3f(6.25f, -18.75f, 0.0f); glEnd(); glPopMatrix(); } void drawText() { glColor3f(0.0f, 1.0f, 1.0f); glRasterPos2f(10.0f, 10.0f); glutBitmapCharacter(GLUT_BITMAP_TIMES_ROMAN_24, 'X'); } void renderScene() { glClear(GL_COLOR_BUFFER_BIT); drawBoard(); glutSwapBuffers(); } void ChangeSize(GLsizei w, GLsizei h) { GLfloat aspectRatio; if (h == 0) h = 1; glViewport(0, 0, w, h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); aspectRatio = (GLfloat)w / (GLfloat)h; if (w <= h) glOrtho(-100.0, 100.0, -100.0 / aspectRatio, 100.0 / aspectRatio, 1.0, -1.0); else glOrtho(-100.0*aspectRatio, 100.0*aspectRatio, -100.0, 100.0, 1.0, -1.0); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); } void mouseClicks(int button, int state, int x, int y) { if (button == GLUT_LEFT_BUTTON && state == GLUT_DOWN) { drawText(); } } int main(int argc, char**argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE); glutInitWindowPosition(600, 400); glutInitWindowSize(800, 600); glutCreateWindow("Tic Tac Toe"); glutDisplayFunc(renderScene); glutReshapeFunc(ChangeSize); glutMouseFunc(mouseClicks); glutMainLoop(); }

I am still working on my AI for my game.

I see that there is a 0 displaying for a rating. That means that an equal amount of people have liked and disliked the comment. While it's obvious why this comment gets a dislike, I wonder if the person liking the comment is just neutralizing anothers vote. (actually I don't wonder at all, it's fairly obvious) I believe that this is an abuse of the user moderation system of likes/dislikes in that liking a awful comment just to knock off a dislike is an abuse of the system.

So I must ask the person that liked that comment, what did you like about it?

BTW, It wasn't me that disliked the comment.
