Professor Fiendish's GRUB SQUISH game! 6t5232
Click around in "The Fiendish Bugs" square to stamp on my bugs, and I'll stamp on yours. It's healthy, fun and educational! We start with exactly 13 bugs each, so see if you can squish all mine before I squish all yours! <!-- Original: Jason Hotchkiss ([email protected]) --> <!-- Web Site: http://www..home.com/jasonhotchkiss --> <!-- This script and many more are available free online at --> <!-- The JavaScript Source!! http://javascript.internet.com --> <!-- Begin /* Information used to draw the ships */ var ship = [[[1,5], [1,2,5], [1,2,3,5], [1,2,3,4,5]], [[6,10], [6,7,10], [6,7,8,10], [6,7,8,9,10]]]; /* Information used to draw sunk ships */ var dead = [[[201,203], [201,202,203], [201,202,202,203], [201,202,202,202,203]], [[204,206], [204,205,206], [204,205,205,206], [204,205,205,205,206]]]; /* Information used to describe ships */ var shiptypes = [["Nosemite",2,4],["Bottigrub",3,4],[ "Navelbug",4,2],[ "Pitworm",5,3]]; var gridx = 16, gridy = 16; var player = [], computer = [], playersships = [], computersships = []; var playerlives = 0, computerlives = 0, playflag=true, statusmsg=""; /* Function to preload all the images, to prevent delays during play */ var preloaded = []; function imagePreload() { var i,ids = [1,2,3,4,5,6,7,8,9,10,100,101,102,103,201,202,203,204,205,206]; window.status = "Preloading images...please wait"; for (i=0;i<ids.length;++i) { var img = new Image, name = "BATT"+ids[i]+".gif"; img.src = name; preloaded[i] = img; } window.status = ""; } /* Function to place the ships in the grid */ function setupPlayer(ispc) { var y,x; grid = []; for (y=0;y<gridx;++y) { grid[y] = []; for (x=0;x<gridx;++x) grid[y][x] = [100,-1,0]; } var shipno = 0; var s; for (s=shiptypes.length-1;s>=0;--s) { var i; for (i=0;i<shiptypes[s][2];++i) { var d = Math.floor(Math.random()*2); var len = shiptypes[s][1], lx=gridx, ly=gridy, dx=0, dy=0; if ( d==0) { lx = gridx-len; dx=1; } else { ly = gridy-len; dy=1; } var x,y,ok; do { y = Math.floor(Math.random()*ly); x = Math.floor(Math.random()*lx); var j,cx=x,cy=y; ok = true; for (j=0;j<len;++j) { if (grid[cy][cx][0] < 100) { ok=false; break; } cx+=dx; cy+=dy; } } while(!ok); var j,cx=x,cy=y; for (j=0;j<len;++j) { grid[cy][cx][0] = ship[d][s][j]; grid[cy][cx][1] = shipno; grid[cy][cx][2] = dead[d][s][j]; cx+=dx; cy+=dy; } if (ispc) { computersships[shipno] = [s,shiptypes[s][1]]; computerlives++; } else { playersships[shipno] = [s,shiptypes[s][1]]; playerlives++; } shipno++; } } return grid; } /* Function to change an image shown on a grid */ function setImage(y,x,id,ispc) { if ( ispc ) { computer[y][x][0] = id; document.images["pc"+y+"_"+x].src = "BATT"+id+".gif"; } else { player[y][x][0] = id; document.images["ply"+y+"_"+x].src = "BATT"+id+".gif"; } } /* Function to insert HTML source for a grid */ function showGrid(ispc) { var y,x; for (y=0;y<gridy;++y) { for (x=0;x<gridx;++x) { if ( ispc ) document.write ('<a href="javascript:gridClick('+y+','+x+');"><img name="pc'+y+'_'+x+'" src="BATT100.gif" width=16 height=16>'); else document.write ('<a href="javascript:void(0);"><img name="ply'+y+'_'+x+'" src="BATT'+player[y][x][0]+'.gif" width=16 height=16>'); } document.write('<br>'); } } /* Handler for clicking on the grid */ function gridClick(y,x) { if ( playflag ) { if (computer[y][x][0] < 100) { setImage(y,x,103,true); var shipno = computer[y][x][1]; if ( --computersships[shipno][1] == 0 ) { sinkShip(computer,shipno,true); alert("You squished my "+shiptypes[computersships[shipno][0]][0]+"!"); updateStatus(); if ( --computerlives == 0 ) { alert("Bah - you win! \n"+ "Hit START A NEW GAME button to play again."); playflag = false; } } if ( playflag ) computerMove(); } else if (computer[y][x][0] == 100) { setImage(y,x,102,true); computerMove(); } } } /* Function to make the computers move.
