Cocos2d-X lua 学习笔记之划屏拖尾特效

这里会不断更新记录我的Cocos2d-X lua学习笔记

1、触碰或滑动屏幕，产生星星例子特效

第一步：生成粒子特效plist文件，命名为touch.plist。用记事本打开，代码如下：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>angle</key>

    <key>angleVariance</key>

    <key>minRadiusVariance</key>
    <real>10</real>
    <key>particleLifespan</key>
    <real>0.5</real>
    <key>particleLifespanVariance</key>
    <real>0</real>
    <key>radialAccelVariance</key>
    <real>0</real>
    <key>radialAcceleration</key>
    <real>100</real>
    <key>rotatePerSecond</key>
    <real>0</real>
    <key>rotatePerSecondVariance</key>
    <real>0</real>
    <key>sourcePositionVariancex</key>
    <real>0</real>
    <key>sourcePositionVariancey</key>
    <real>0</real>
    <key>sourcePositionx</key>
    <real>0</real>
    <key>sourcePositiony</key>
    <real>0</real>
    <key>speed</key>
    <real>20</real>
    <key>speedVariance</key>
    <real>0</real>
    <key>startColorAlpha</key>
    <real>0</real>
    <key>startColorBlue</key>
    <real>1</real>
    <key>startColorGreen</key>
    <real>1</real>
    <key>startColorRed</key>
    <real>1</real>
    <key>startColorVarianceAlpha</key>
    <real>1</real>
    <key>startColorVarianceBlue</key>
    <real>0</real>
    <key>startColorVarianceGreen</key>
    <real>0</real>
    <key>startColorVarianceRed</key>
    <real>0</real>
    <key>startParticleSize</key>
    <real>0</real>
    <key>startParticleSizeVariance</key>
    <real>8</real>
    <key>tangentialAccelVariance</key>
    <real>10</real>
    <key>tangentialAcceleration</key>
    <real>0</real>
    <key>textureFileName</key>
    <string>star.jpg</string>
  </dict>
</plist>>

第二步：在触碰事件相应函数中，添加代码

emitter = cc.ParticleSystemQuad:create("touch.plist")
emitter:setAnchorPoint(0,0)
emitter:setPosition(px,py)
