canvas动画效果..高手指点
已经在canvas画布上画出了类似九宫格的形状:
现在想这九个小方块按照设定的轨迹移动最后定格。轨迹没有写 我想知道是怎么样的步骤。。。
贴出代码:
function getCursorPosition(e){ var x; var y; if (e.pageX != undefined && e.pageY != undefined) { x = e.pageX; y = e.pageY; }else{ //the position relativeto the docment x = e.clientX + document.body.scrollLeft + document.documentElement.scrollLeft; y = e.clientY + document.body.scrollTop + document.documentElement.scrollTop; } //coordiantes to the canvas var c = document.getElementById("logo"); x -= c.offsetLeft; y -= c.offsetTop; //if the mouse position if(x>=368 && x<=400 && y>=10 && y<=50){ c_context = c.getContext("2d"); //there have a block box to discovery the text "H" c_context.fillStyle = "#323232"; c_context.beginPath(); c_context.moveTo(368,10); c_context.lineTo(400,10); c_context.lineTo(400,50); c_context.lineTo(368,50); c_context.fill(); //there have nine orange box instead if the text "H" c_context.fillStyle = "#f99405"; for(i = 370 ;i<411; i+=14){ for(j=10; j<51;j+=14){ c_context.beginPath(); c_context.moveTo(i,j); c_context.lineTo(i+13,j); c_context.lineTo(i+13,j+13); c_context.lineTo(i,j+13); c_context.fill(); //the boxes move to anywhere they want //这里是想加的代码 但不知道怎么写。(每画出一个小方块就按照预定的轨迹移动) } } }}
