AS画图篇(1)
使用方法：把代码拷到帧中就可看到效果
用鼠标任意画线
效果：可按住鼠标任意画线，可作简单的涂鸭工具
代码：
createEmptyMovieClip("xian",1);
with (xian) {
_root.onMouseMove = function() {
if (draw) {
_root.lineStyle(0,0x000000, 100);
_root.lineTo(_root._xmouse,_root._ymouse);
}
};
_root.onMouseDown = function() {
draw = true;
_root.moveTo(_root._xmouse,_root._ymouse);
};
_root.onMouseUp = function() {
draw = false;
};
}
用鼠标任意画直线
效果：类似flash中的直线工具
代码：
createEmptyMovieClip("line", n);
with (line) {
lineStyle(1, 0x000000, 100);
moveTo(0, 0);
lineTo(100, 100);
line._visible = 0;
}
_root.onMouseDown = function() {
qidian_x = _root._xmouse;
qidian_y = _root._ymouse;
with (line) {
_x = qidian_x;
_y = qidian_y;
_xscale = 0;
_yscale = 0;
_visible = 1;
}
};
_root.onMouseMove = function() {
endX = _root._xmouse;
endY = _root._ymouse;
if (_root.line != "_root.line" && key.isdown(16)){
if (Math.abs(endX-qidian_x)>Math.abs(endY-qidian_y)){
setProperty(_root.line, _xscale, endX-qidian_x);
setProperty(_root.line,_yscale, endX-qidian_x);
} else {
setProperty(_root.line, _xscale, endY-qidian_y);
setProperty(_root.line, _yscale, endY-qidian_y);
}
} else {
setProperty(_root.line, _xscale,endX-qidian_x);
setProperty(_root.line, _yscale,endY-qidian_y);
}
};
_root.onMouseUp = function() {
if (_root._xmouse-qidian_x != 0) {
i++;
Objectx = "Copy" add i;
duplicateMovieClip(_root.line, Objectx, i);
setProperty(Objectx, _x, qidian_x);
setProperty(Objectx, _y, qidian_y);
_root.i = i;
}
setProperty(_root.line, _visible, 0);
};
用鼠标任意画矩形
效果：类似flash中的矩形工具
代码：
createEmptyMovieClip("line", n);
with (line) {
lineStyle(0.1, 0x000000, 100);
moveTo(0, 0);
lineTo(100, 0);
lineTo(100, 100);
lineTo(0, 100);
lineTo(0,0);
line._visible = 0;
}
_root.onMouseDown = function() {
qidian_x = _root._xmouse;
qidian_y = _root._ymouse;
with (line) {
_x = qidian_x;
_y = qidian_y;
_xscale = 0;
_yscale = 0;
_visible = 1;
}
};
_root.onMouseMove = function() {
endX = _root._xmouse;
endY = _root._ymouse;
if (_root.line != "_root.line" && key.isdown(16)){
if (Math.abs(endX-qidian_x)>Math.abs(endY-qidian_y)){
setProperty(_root.line,_xscale, endX-qidian_x);
setProperty(_root.line, _yscale, endX-qidian_x);
} else {
setProperty(_root.line,_xscale, endY-qidian_y);
setProperty(_root.line,_yscale, endY-qidian_y);
}
} else {
setProperty(_root.line, _xscale,endX-qidian_x);
setProperty(_root.line, _yscale,endY-qidian_y);
}
};
_root.onMouseUp = function() {
if (_root._xmouse-qidian_x != 0) {
i++;
Objectx = "Copy" add i;
duplicateMovieClip(_root.line,Objectx, i);
setProperty(Objectx, _x, qidian_x);
setProperty(Objectx, _y, qidian_y);
_root.i = i;
}
setProperty(_root.line, _visible, 0);
};
用鼠标任意画圆、椭圆
效果：类似flash中的工具
代码：
createEmptyMovieClip("line", n);
with (line) {
for (n=1; n<400; n++) {
a = 50*Math.cos(n*Math.PI/180);
b = 50*Math.sin(n*Math.PI/180);
c = 50*Math.cos((n+1)*Math.PI/180);
d = 50*Math.sin((n+1)*Math.PI/180);
lineStyle(0.01, 0x000000, 50);
moveTo(a+50, b+50);
lineTo(c+50, d+50);

setProperty(Objectx, _x, qidian_x);
setProperty(Objectx, _y, qidian_y);
_root.i = i;
}
setProperty(_root.line, _visible, 0);

两定点画虚线
代码：
MovieClip.prototype.dashTo = function(startPoint, destPoint, dashLength, spaceLength) {
var x = destPoint.x-startPoint.x;
var y = destPoint.y-startPoint.y;
var hyp = Math.sqrt((x)*(x)+(y)*(y));
var units = hyp/(dashLength+spaceLength);
var dashSpaceRatio = dashLength/(dashLength+spaceLength);
var dashX = (x/units)*dashSpaceRatio;
var spaceX = (x/units)-dashX;
var dashY = (y/units)*dashSpaceRatio;
var spaceY = (y/units)-dashY;
this.moveTo(startPoint.x, startPoint.y);
while (hyp>0) {
startPoint.x += dashX;
startPoint.y += dashY;
hyp -= dashLength;
if (hyp<0) {
startPoint.x = destPoint.x;
startPoint.y = destPoint.y;
}
this.lineTo(startPoint.x,startPoint.y);
startPoint.x += spaceX;
startPoint.y += spaceY;
this.moveTo(startPoint.x,startPoint.y);
hyp -= spaceLength;
}
this.moveTo(destPoint.x, destPoint.y);
};
createEmptyMovieClip("DrawingSpace", 1);
with (DrawingSpace) {
lineStyle(0, 0x000000, 100);
dashTo({x:300, y:0}, {x:0, y:400}, 3, 10);
}
从一点到另一点画虚线
代码：
function DrawDottedLine(targetMC, linewidth, fromX, fromY, toX, toY) {
// targetMC: 目标MovieClip德InstanceName;
// linewidth: 线宽;
// fromX, fromY: 从(fromX, fromY)处开始画;
// toX, toY: 画到(toX, toY)处;
var x, y;
eval(targetMC).lineStyle(lineWidth, 0x000000, 100);
// 线的颜色是黑色(0x000000)
eval(targetMC).moveTo(fromX, fromY);
x = fromX;
y = fromY;
while (x<toX) {
x = x+4/(Math.sqrt((toY-fromY)*(toY-fromY)+(toX-fromX)*(toX-fromX)))*(toX-fromX);
y = y+4/(Math.sqrt((toY-fromY)*(toY-fromY)+(toX-fromX)*(toX-fromX)))*(toY-fromY);
eval(targetMC).lineTo(x, y);
x = x+4/(Math.sqrt((toY-fromY)*(toY-fromY)+(toX-fromX)*(toX-fromX)))*(toX-fromX);
y = y+4/(Math.sqrt((toY-fromY)*(toY-fromY)+(toX-fromX)*(toX-fromX)))*(toY-fromY);
eval(targetMC).moveTo(x, y);
}
}
createEmptyMovieClip("obj",1);//建一空影片
DrawDottedLine("_root.obj", 1, 10, 10, 200, 300);//调用函数
从场景的左上角到鼠标画虚线
代码：
x = 0;
y = 0;//场景左上角的坐标
l = 0;
mx = _root._xmouse;
my = _root._ymouse;//鼠标的坐标
ml = Math.sqrt(mx*mx+my*my);//三角形的斜边长
_root.moveto(0, 0);//画线的起点为场景左上角的坐标
_root.linestyle(0.1, 0x000000, 100);
// 下面用三角函数求出每一段虚线的端点坐标，然后用循环重复画一条短线和空格。直到线的终点位置。
while (l<ml) {
l += 5;
// 短线的长
x = l*mx/ml;
y = l*my/ml;
_root.lineto(x, y);
// 将绘图点移动到相当于短线长的，且与短线在同一直线的位置。即一个空格
l += 5;
x = l*mx/ml;
y = l*my/ml;
_root.moveto(x, y);
}
不错的画线函数，自定义点、线的样式、填充
function Shape() {
this.points = [];
this.lines = false;
tthis.filled = false;
tthis.lineStyle = null;
this.t = eval(_target);
}
Shape.prototype.addPoint = function(x, y) {
this.points[this.points.length] = {x:x, y:y};
};
Shape.prototype.removePoint = function() {
this.points.pop();
};
Shape.prototype.draw = function(w, c, a) {
if (this.points.length>1) {
this.lineStyle = {w:w, c:c,a:a};
this.t.lineStyle(w, c, a);var i = 0;
var l = this.points.length;
while (i<l) {
this.t.lineTo(this.points[i].x,this.points[i].y);
++i;
}
this.lines = true;
}
};
Shape.prototype.fill = function(c, a) {
if (this.points.length>1) {
if (this.lines) {
this.clear();
this.t.lineStyle(this.lineStyle.w,this.lineStyle.c, this.lineStyle.a);
} else {
this.t.lineStyle(0,0xFFFFFF, 0);
if (this.filled){
this.clear();
}
}
this.t.beginFill(c, a);
var i = 0;
var l = this.points.length;
while (i<l) {
this.t.lineTo(this.points[i].x,this.points[i].y);
++i;
}
this.t.endFill();
this.filled = true;
}
};
Shape.prototype.getX = function() {
if (this.points.length) {
return this.points[this.points.length-1].x;
}
};
Shape.prototype.getY = function() {
if (this.points.length) {
return this.points[this.points.length-1].y;
}
};
g = new Shape();
g.addPoint(0, 100);
g.addPoint(100, 100);
g.addPoint(100, 0);
g.addPoint(0, 0);
g.fill(0x339900, 100);
g.draw(5, 0x000000, 100);
