运行一段时间Crash

谁帮我看看这个log
多个Sprite在运行多个Action（包括Sequnece， Spawn等等）之后会产生crash

第一种

顺便再指导一下小弟如何看这样的Log吧。

#2

1.什么问题？

看贴出的函数堆栈可以初步确定的是对Action的控制不够，这种情况一般是出现在混用多种运动，但是却没注意调用者的生命周期。

建议贴出代码。或者逐步缩小代码规模调试。

2.如何看？

版主大神，版主大哥，下面的帖子我看了，但是您说的『对Action的控制不够』，这个有什么好的建议么？ 我有在runAction之前stopAllActions啊。能否再指点一二呢？

主要是以下的代码，并且会频繁调用。

void PetSprite::animateToPose(std::string &poseName, float duration)
{
ValueMap& poseMap = mPosesValueMap.asValueMap();
if(poseMap.size() > 0){
bool firstObj = true;

std::string partName = modelPart->first;
auto partSprite = modelPart->second;
int tag = partSprite->getTag();
if(tag == PART_OBJ_ANIMATION_TAG || tag == PART_OBJ_ANIMATION_TAG2){
//describe the part position and anim informations
ValueMap posePartMap;
//if part name in pose, use pose anim, others use standy pose
if(poseMap.count(partName) > 0){
posePartMap = poseMap.asValueMap();
}else{
posePartMap = mPosesValueMap"standby"].asValueMap().asValueMap();
}

            //set up frames
            ValueVector partFrameArray = posePartMap"frames"].asValueVector();
            bool singleFrame = partFrameArray.size() > 1 ? false : true;

『对Action的控制不够』，这个有什么好的建议么？

你要能清楚的知道引擎的在每一帧，你创建的对象的状态（比如每一帧他是在做什么运动，要不要停止，到了触发回调的时候了吗，要不要切换动作，而不是等逻辑一复杂了就stopAllActions）。特别是调用者的生命周期。这是游戏逻辑层的东西了。你的代码很多变量我都不知道是干嘛的，建议注释掉部分代码进行排查。

只能说C++不适合初学者使用，还是用lua吧

#7

我也是被赶鸭子上架的，我是做java的。。。。。对C++仅仅停留在阅读的层面。。这些代码是我硬着头皮写的。。。

#8

谢谢版主的耐心解答。:5:
只有一个界面，所有的Sprite我没有进行release，给Sprite run一个新的action的时候，我就调用了一个stopAllActions。。。。

#9

版主大神，我stopAllAction是为了给这个Sprite重新run一个action啊。我这边好多出错，但是都是报在cocos2dx的libcocos2dcpp.so中
比如这一种Log

这些都不是必现，就是在之前的动作在运行的时候，要换一个Action，这个时候我才调用stopAllAction然后在create响应的Action，执行runaction。

#10

有办法给我一个简单重现的例子吗？

#11

网事版主大神，我这两天终于做了一个demo能够重现问题了，请问如何将代码给你呢？

我用你给的那个ndk_stack的连接试了，每次log都不一样，但是主要就集中在ActionManager 、Ref release、Spawn update等这几个方面。

#12

网事大神，请问我怎么把重现例子的代码给你呢？

#13

网事大神你好，重现代码如下
Java层触发JNI 代码执行cocos2dx方法：
Java代码为：
public static native void test();

JNI代码为：
extern “C” void Java_org_cocos2dx_cpp_AppActivity_test()
{
log("//////////////////////////////");
HelloWorld * helloWorld = static_cast<HelloWorld *>(scene->getChildByTag(1));
helloWorld->click();
}

cocos2dx中的代码为：

void HelloWorld::click()
{
for (int i = 0 ; i < 1000; i++) {
auto rotate = RotateTo::create(1, 180);
auto scale = ScaleTo::create(1, 0.1f);
auto rotate1 = RotateTo::create(1, 0);
auto scale1 = ScaleTo::create(1, 1.f);
auto spawn = Spawn::create(rotate, scale, NULL);
auto spawn1 = Spawn::create(rotate1, scale1, NULL);
auto sequence = Sequence::create(spawn, spawn1, NULL);
_Demosprite->stopAllActions();
_Demosprite->runAction(sequence);
}
}

因为Java层没有触发的地方，我将test（）的调用写在@Override
public void onBackPressed() {
//super.onBackPressed();
test();
}

运行成功，然后按back键，则无响应，稍等一会就退出应用而不产生crash dialog。
每次出现的log都不相同

#14

1.和for循环有关系么？（应该是没有关系的）

2.直接在c++层调用click()有问题吗？（应该是没有问题的）

3.如果上面两点确认了，原因应该是不可以在UI线程调用openGL线程的Cocos2d-x相关函数，这样会导致各种各样的crash。

#15

版主大人，

1.for循环没有关系，之所以用for循环是为了让该问题更好的重现

2.直接在C++代码中调用是没有问题的

3.for循环次数比较少的话，则不会crash。 那么我应该如何改进呢？ 用类似timer的定时或者设置布尔类型的flag，让update方法去调用，这样不会有问题吧。我尝试了设置布尔参数，不会crash。

谢谢版主耐心给我解答。

#16

转到主线程中去调用，先调用一个全局函数，然后这个全局函数调用performFunctionInCocosThread，在这个的lanbam中去做主线程的操作
