Hello,
I need to access the “this” pointer in an AsyncTask. In order to do so, I tried to implement the first solution described here Non-static AsyncTask.
Unfortunately I have an issue with one of the instance variable which is initialized to nullptr in the constructor but, if I try to access it using the pointer passed to the task, I get a non-null pointer:
THE CONSTRUCTOR
//...
this->currFocus=nullptr;//the variable I m trying to access from the task
AsyncTaskManager *task_mgr = AsyncTaskManager::get_global_ptr();
PT(GenericAsyncTask) task;
task = new GenericAsyncTask("cameraTask", &cameraTask, this);
task_mgr->add(task);
//...
//THE TASK
AsyncTask::DoneStatus MyClass::cameraTask(GenericAsyncTask *task, void *data) {
//Here I try to use the technique described in the other thread
MyClass * cs = (MyClass*)data;
/*here, I expect the following command to print "0" but it prints
a valid memory address*/
std::cout << cs->getCurrFocus() << std::endl;
return AsyncTask::DS_cont;
}
for instance, the method getCurrFocus is just a plain getter:
NodePathWrapper * MyClass::getCurrFocus(){
return this->currFocus;
}
am I missing something?
