图片flash动态缓冲图片导航制作详解

flash动态缓冲图片导航制作详解

The buffer formula is very useful in making special effects.The famous Samsung navigation menu uses this formula. Manywebsites are now in the limelight, and buffer navigation is oneof the highlights. This article takes the navigation of aGermanwebsite as an example to explain the manufacture of buffernavigation. This effect is done by me and the solvent. Heprovides the coordinate algorithm, and I provide the scalingalgorithm.

This example demonstrates the effect

The part of the mouse across the picture will become largerProduction ideas

Picture zoom control

Using the buffer formula to set the zoom ratio of the picture,if the mouse glides through a picture, zoom in 1.8 times. Ifthe serial number of the other picture is 1 different from thatof the picture, the picture on both sides of the picture ismagnified 1.4 times, and the other is of the original size.Picture coordinate control

When a picture is enlarged, the coordinates of the adjacentpictures are equal to the coordinates of the image, plus halfof the width of the two pictures, so that the pictures arearranged without distance.

Line and text control

Lines are implemented using line drawing functions, and thecoordinates and scale of text are the same as those of thecorresponding pictures.

Making process

1, startFlash, create anewmovie, set the size of 600px*200px.Get ready, like the material in the picture. The actual namesof the pictures are zjs0 to zjs4, and the literal names of thetext are Z0 to z4.

The intermediate image coordinates set (300130) , select all thepictures, arranged according to CTRLK panel set to top out, makethe same picture, y coordinates, X coordinate picturecontrolled by AS. In the same way that y coordinates the samecharacters, and adjust the spacing of text and pictures.2, add the following code on the first frame in the main sceneX / / get intermediate image coordinates

For (VaR = I = 0; i<5; i++) {

This["ZJS", +i] .n = i;

Each picture / / MC define a variable

This["ZJS", +i] .onRollOver = function () {

Control = true;

Mouse over the picture is true / /

} ;

This["ZJS", +i] .onRollOut = function () {

Control = false;

The picture is false when the mouse out of /

} ;

}

OnEnterFrame = function () {

For (VaR = k = 0; k<5; k++) {

This["Z", +k] ._x = this[, "ZJS", +k] ._x;

X/text should be equal to the X coordinate coordinate pictureThis["Z", +k] ._xscale = this[, "ZJS", +k] ._xscale;

This["Z", +k] ._yscale = this[, "ZJS", +k] ._yscale;

/ / text and pictures the same zoom ratio

}

If (control) {

Mouse_in () ;

} else {

Mouse_out () ;

}

/ / call the function condition of true or false when} ;

/ / coordinate setting function

Function, setX () {

For (VaR k = -2; k<3; k++) {

This["ZJS" + (k+2) ] ._x = myx+this["ZJS" +2] ._width*k;In the middle picture is / / no distance arrangement

}

For (VaR k = Number (temp 1) +1; k<5; k++) {

//temp1 is the variable value under the maximum scaled picture

this was mc1 = ["zjs' + k] ;this was mc2 = ["zjs' + (k - 1) ] ;

/ /此图片右边的其它图片mc1. _x = mc2. _x + (mc2. _width + mc1. _ width) / 2 - 1;/ /设置这些图片的x坐标, 1为消除图片间的空隙

}for (where k = number (temp1) - 1; k > 1; k) {this was mc1 = ["zjs' + k] ;this was mc2 = ["zjs' + (k + 1) ] ;mc1. _x = mc2. _x - (mc2. _width + mc1. _ width) / 2 + 1;}

/ /缩放比例最大的图片的左边的图片的x坐标设置myline () ;

/ /图片下方的线条

}

/ /比例缩放函数function move _ scale (x, obj) {speed = (x - obj. _ xscale) *.65 + speed * 0.6;obj. _ xscale + = speed;obj. _ yscale + = speed;

/ /缓冲公式, x为图片的缩放比例, obj为mc}

/ /鼠标滑过图片时, 图片的缩放、 x坐标设置函数function mouse _ () {for (i = 0; i < 5; i + +) {where mc = this ["zjs" +] ;

/ /如果鼠标位于图片的上方, 图片放大1.8倍t emp 1 = mc.n;

} else if (math.abs (mc.n-temp1) = = 1) {move _ scale (140, mc) ;

/ /两侧的图片比例放大1.4倍

} else {move _ scale (100, mc) ;

/ /其它的图片为原始大小

}

}setx () ;

/ /设置图片的x坐标

}

/ /鼠标移出图片时, 图片的缩放、 x坐标设置函数function mouse _ out () {for (i = 0; i < 5; i + +) {

}setx () ;

/ /坐标复原

}

/ /线条函数function myline () {createemptymovieclip ("line", 1) ;

/ /创建一个空影片with (line) {linestyle (0. 1, 0xff9933, 100) ;moveto (zjs0. _ x - zjs0. _ width / 2, zjs0. _y + 10) ;lineto (zjs4. _ x + zjs4. _ width / 2, zjs4. _ y + 10) ;/ /图片下方水平的直线moveto (zjs0. _ x - zjs0. _ width / 2, zjs0. _y + 5) ;

}

}

按ctrl + enter测试,本例制作完成.掌握原理后,加上好的创意,相信你能做出更好的特效.
