推薦：Flash實例“蝶戀花”制作過程深入剖析
通過這個蝴蝶在花叢中翻飛的實例我們可以學(xué)習(xí)Flash圖層、引導(dǎo)線運動、幀與補間動畫等技術(shù)。主要使用工具：箭頭工具(選擇工具)、任意變形工具、鉛筆工具。請大

　　主要是利用Flash Actionscript一步一步學(xué)習(xí)Flash高射炮簡單游戲的制作過程，最終效果只是一個簡單的演示，假如你有愛好可以繼續(xù)深入學(xué)習(xí)！

　　開篇前，先把所有的演示動畫的源程序提供給大家：

　　點擊這里下載本教程中所有演示動畫的源文件(解壓密碼：www.zhaotila.cn)

　　第一步：首先簡單的制作一個鼠標(biāo)動畫，繪制一個鼠標(biāo)的圖，自己定。然后選擇第一幀輸入下面代碼：

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};

　　效果如下：

　　第二步：繪制一個坦克，分成兩部分，如下面：

　　把下面的命名實例名為tank

　　代碼如下：

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle = 180;
}
if (mousex>=0 && mousey<0) {
angle = 360;
}
this.cannon._rotation = angle*-1;
};

　　效果（無角度限制）：

　　第三步：我這里設(shè)置轉(zhuǎn)動的一定的角度。

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle = 180;
}
if (mousex>=0 && mousey<0) {
angle = 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
this.cannon._rotation = angle*-1;
};

　　效果如下：

　　然后是計算開火的目標(biāo)：

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle = 180;
}
if (mousex>=0 && mousey<0) {
angle = 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
firepower = Math.sqrt(mousex*mousex mousey*mousey);
if (firepower>200) {
firepower = 200;
}
this.cannon._rotation = angle*-1;
};

　　開火的制作：

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle = 180;
}
if (mousex>=0 && mousey<0) {
angle = 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
firepower = Math.sqrt(mousex*mousex mousey*mousey);
if (firepower>200) {
firepower = 200;
}
this.cannon._rotation = angle*-1;
};
function onMouseDown() {
angle = tank.cannon._rotation-1
start_ball_x = tank._x 48*Math.cos(angle*Math.PI/180);
start_ball_y = tank._y 48*Math.sin(angle*Math.PI/180);
attachMovie("cannonball", "cannonball", 3, {_x:start_ball_x, _y:start_ball_y});
}

　　效果如下：

　　開火出來炮彈：

Mouse.hide();
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle = 180;
}
if (mousex>=0 && mousey<0) {
angle = 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
firepower = Math.sqrt(mousex*mousex mousey*mousey);
if (firepower>200) {
firepower = 200;
}
this.cannon._rotation = angle*-1;
};
function onMouseDown() {
angle = tank.cannon._rotation-1;
start_ball_x = tank._x 48*Math.cos(angle*Math.PI/180);
start_ball_y = tank._y 48*Math.sin(angle*Math.PI/180);
cannonball_fired = attachMovie("cannonball", "cannonball_" _root.getNextHighestDepth(), _root.getNextHighestDepth(), {_x:start_ball_x, _y:start_ball_y});
cannonball_fired.dirx = Math.cos(angle*Math.PI/180)*firepower;
cannonball_fired.diry = Math.sin(angle*Math.PI/180)*firepower;
cannonball_fired.onEnterFrame = function() {
this._x = this.dirx/50;
this._y = this.diry/50;
};
}

　　效果如下：

　　最后再加以具體的限制一下炮彈：

Mouse.hide();
gravity = 2;
attachMovie("crosshair", "crosshair", 1);
attachMovie("tank", "tank", 2, {_x:230, _y:350});
crosshair.onEnterFrame = function() {
this._x = _xmouse;
this._y = _ymouse;
};
tank.onEnterFrame = function() {
mousex = _xmouse-this._x;
mousey = (_ymouse-this._y)*-1;
angle = Math.atan(mousey/mousex)/(Math.PI/180);
if (mousex<0) {
angle = 180;
}
if (mousex>=0 && mousey<0) {
angle = 360;
}
if (angle>160) {
angle = 160;
}
if (angle<20) {
angle = 20;
}
firepower = Math.sqrt(mousex*mousex mousey*mousey);
if (firepower>200) {
firepower = 200;
}
this.cannon._rotation = angle*-1;
};
function onMouseDown() {
angle = tank.cannon._rotation-1;
start_ball_x = tank._x 48*Math.cos(angle*Math.PI/180);
start_ball_y = tank._y 48*Math.sin(angle*Math.PI/180);
cannonball_fired = attachMovie("cannonball", "cannonball_" _root.getNextHighestDepth(), _root.getNextHighestDepth(), {_x:start_ball_x, _y:start_ball_y});
cannonball_fired.dirx = Math.cos(angle*Math.PI/180)*firepower;
cannonball_fired.diry = Math.sin(angle*Math.PI/180)*firepower;
cannonball_fired.onEnterFrame = function() {
this.diry = gravity;
this._x = this.dirx/50;
this._y = this.diry/50;
};
}

　　效果如下：
