Access violation on sprite

cocos2d-x C++
#1

So I have the following function

void Game::drill(Brick *brick, PhysicsBody *body)
{
    ...
    CallFunc *deletion = CallFunc::create([&]()
	{
		brick->setOpacity(0);
		body->setCollisionBitmask(7);
		body->setContactTestBitmask(true);
		brick->setPhysicsBody(body);
	});
    ...
}

When I call the deletion callfunc, I receive an access violation: Access violation executing location 0x00000000.

Why?

#2

must be out of scope. Place a break point and step through your code and check in the debugger that it is in scope at that time.

#3

Exactly what slackmoehrle pointed out. You need to pass by value, not by reference, so use ‘=’ instead of ‘&’, like the following:

CallFunc *deletion = CallFunc::create([=]()
{ 
....

Thanks a lot, now it works. I’ve been struggling with this issue for 3 days now :grinning:
