/* This code lets you play Tic-Tac-Toe against yourself! If you wish you may have your friend play against you, the bottom-line is that this version is NOT on the network and both players get to use the same DISPLAY.. I hope you enjoy playing this game and please, please send your comments to Solai, e-mail: solaiapp@ucunix.san.uc.edu Looking forward to hear some favourable comments and the due modifications for a next version. Thanks. -solaii P.S : Developed solely using Xlib. */ #include #include #include Display *mydisplay; Window mywindow; GC mygc; unsigned long myfore,myback; XImage *myimage; int myscreen; int I,J,s[3][3],IS; int IW,TN; Font font; main(argc,argv) int argc; char **argv; { XEvent myevent; KeySym mykey; XSizeHints myhint; char text[10]; char *b[5]; int done,done1; int i,j,x,y; XColor color; printf("\nxtic (Tic-Tac-Toe) 1993\n"); printf("developed by Solaiappan, O @ Comp.Sc/U.C\n"); mydisplay = XOpenDisplay(""); myscreen = DefaultScreen(mydisplay); b[0] = " PLAYER O WON "; b[1] = " PLAYER + WON "; b[2] = " PLAY IS DRAW "; b[3] = "PRESS ANY KEY TO EXIT"; b[4] = "PRESS BUTTON TO CONTINUE"; /* Default Pixel Values */ /* Default Program-Specified Window Position and Size */ myhint.x=200; myhint.y=300; myhint.width=440; myhint.height=440; myhint.flags = PPosition | PSize; IS = 0; /* Window Creation */ mywindow = XCreateSimpleWindow(mydisplay,DefaultRootWindow(mydisplay), myhint.x,myhint.y,myhint.width,myhint.height,5, myfore,myback); XSetStandardProperties(mydisplay,mywindow,"Tic-Tac-Toe","ttt",None,argv, argc,&myhint); /* GC Creation and Initialization */ mygc = XCreateGC(mydisplay,mywindow,0,0); myback = WhitePixel(mydisplay,myscreen); myfore = BlackPixel(mydisplay,myscreen); XSetForeground(mydisplay,mygc,myfore); for(i=0;i<=2;++i) for(j=0;j<=2;++j) s[i][j] = -1; XSetForeground(mydisplay,mygc,myback); /* Input Event Selection */ XSelectInput(mydisplay,mywindow, ButtonPressMask | ExposureMask | KeyPressMask); /* Window Mapping */ XMapRaised(mydisplay,mywindow); font = XLoadFont(mydisplay,"10x20"); XSetFont(mydisplay,mygc,font); /* Main Event-Reading Loop */ done1 = 0; while(done1 == 0) { done = 0; while(done == 0) { /* Read the Next Event */ XNextEvent(mydisplay, &myevent); switch(myevent.type) { /* Repaint the Window on Expose Events */ case Expose: do_set_up(); break; /* Process Mouse Button Presses */ case ButtonPress: x = myevent.xbutton.x; y = myevent.xbutton.y; I = -1; J = -1; if(x >= 20 && x <= 140) I = 0; if(x >=160 && x <= 280) I = 1; if(x >= 300 && x <= 420) I = 2; if(y >= 20 && y <= 140) J = 0; if(y >= 160 && y <= 280) J = 1; if(y >= 300 && y <= 420) J = 2; if(I >= 0 && J >= 0 && s[I][J] == -1) symbol(); check(); if(IW >= 0) done = 1; if(TN == 9) done = 1; break; case KeyPress : exit(1); } } XSetForeground(mydisplay,mygc,myfore); XFillRectangle(mydisplay,mywindow,mygc,70,175,300,90); XSetForeground(mydisplay,mygc,myback); XFillRectangle(mydisplay,mywindow,mygc,80,185,280,70); XSetForeground(mydisplay,mygc,myfore); XSetBackground(mydisplay,mygc,myback); if(TN == 9) XDrawImageString(mydisplay,mywindow,mygc,150,205,b[2],15); if(IW >= 0) XDrawImageString(mydisplay,mywindow,mygc,140,208,b[IW],15); XDrawImageString(mydisplay,mywindow,mygc,100,228,b[4],24); XDrawImageString(mydisplay,mywindow,mygc,115,248,b[3],21); XNextEvent(mydisplay,&myevent); switch (myevent.type) { case ButtonPress : done = 0; for(i=0;i<=2;++i) for(j=0;j<=2;++j) s[i][j] = -1; do_set_up(); TN = 0; IS = 0; break; case KeyPress : done1 = 1; break; } } } /* This function sets up game workspace. */ do_set_up() { int i,j; int x,y; XSetForeground(mydisplay,mygc,myfore); XFillRectangle(mydisplay,mywindow,mygc,0,0,480,480); XSetForeground(mydisplay,mygc,myback); for(i=0;i<=2;++i) for(j=0;j<=2;++j) { x = 20 +140*i; y = 20 +140*j; XFillRectangle(mydisplay,mywindow,mygc,x,y,120,120); } for(i=0;i<=2;++i) for(j=0;j<=2;++j)Symbol(i,j,s[i][j]); } /* This function draws symbols one after another. */ symbol() { int x,y; XSetForeground(mydisplay,mygc,myfore); TN = TN + 1; s[I][J] = IS; x = 20 + 140*I; y = 20 + 140*J; if(IS == 0) { x = x + 20; y = y + 20; XFillArc(mydisplay,mywindow,mygc,x,y,80,80,0,360*64); XSetForeground(mydisplay,mygc,myback); x = x + 15; y = y + 15; XFillArc(mydisplay,mywindow,mygc,x,y,50,50,0,360*64); } if(IS == 1) { x = x + 50; y = y + 20; XFillRectangle(mydisplay,mywindow,mygc,x,y,20,80); x = x - 30; y = y + 30; XFillRectangle(mydisplay,mywindow,mygc,x,y,80,20); } IS = IS + 1; IS = IS % 2; } Symbol(II,JJ,V) int II,JJ,V; { int x,y; XSetForeground(mydisplay,mygc,myfore); x = 20 + 140*II; y = 20 + 140*JJ; if(V == 0) { x = x +20; y = y + 20; XFillArc(mydisplay,mywindow,mygc,x,y,80,80,0,360*64); XSetForeground(mydisplay,mygc,myback); x = x + 15; y = y + 15; XFillArc(mydisplay,mywindow,mygc,x,y,50,50,0,360*64); } if (V == 1) { x = x + 50; y = y + 20; XFillRectangle(mydisplay,mywindow,mygc,x,y,20,80); x = x - 30; y = y + 30; XFillRectangle(mydisplay,mywindow,mygc,x,y,80,20); } } check() { int i,j,k; IW = -1; for(k=0;k<=1;++k) { for(i=0;i<=2;++i){ j = 0; while(j<=2) { if(k != s[i][j]) break; j = j + 1; } j = j - 1; if(j == 2 && k == s[i][j]) IW = k; j = 0; while(j<=2) {if(k != s[j][i]) break; j = j + 1; } j = j - 1; if(j == 2 && k == s[j][i]) IW = k; } if(s[0][0] == k && s[1][1] == k && s[2][2] == k) IW = k; if(s[0][2] == k && s[1][1] == k && s[2][0] == k) IW = k; } }
