Putting Time Between Spawns

cocos2d-x C++
#2

Either:
a. Schedule a function call to create the sprites, or
b. Run a Sequence action that contains a DelayTime action followed by a CallFunc action.

I’m trying to write a code that creates a sprite repeatedly forever.But I don’t know how can i put time between the creations.Can you help me ?

#5

How can I write a valid CallFunc code makes that :
this->addChild(bowser);

#6

I’m not sure what you mean. You want an action that includes a CallFunc action that calls this->addChild(bowser);?

Something like:

this->runAction(Sequence::create(
    DelayTime::create(5.f),
    CallFunc::create([=](){
        this->addChild(bowser);
    }),
    nullptr));
#7

Yeah I mentioned it.But when I use the code you wrote there is no error at compiling but when I run it on my phone it stops working after the delay.

#3

I do something like this sometimes:

// use a sequence of calls to display instructions to user
    // and then start the game
    cocos2d::CallFunc* _purpleKernel = cocos2d::CallFunc::create([=]() {
        this->purpleKernelTimer();
    });
    cocos2d::CallFunc* _ready = cocos2d::CallFunc::create([=]() {
        this->readyTimer();
    });
    cocos2d::CallFunc* _set = cocos2d::CallFunc::create([=]() {
        this->setTimer();
    });
    cocos2d::CallFunc* _pop = cocos2d::CallFunc::create([=]() {
        this->popTimer();
    });
    cocos2d::CallFunc* _game = cocos2d::CallFunc::create([=]() {
        this->gameTimer();
    });
    cocos2d::DelayTime* _delay = cocos2d::DelayTime::create(1);

    runAction(cocos2d::Sequence::create(_purpleKernel, _delay,_delay, _ready, 
        _delay, _set, _delay, _pop, _delay, _game, NULL));

    schedule(schedule_selector(GameScene::purpleKernel), 10);

What do you mean by “stops working”? Does it crash? Are there any error messages in the logs?

#9

Did you see the code that I posted below? It works.

#10

Yeah it crashes and gives this error:

#11

Saw and tried it but I want to know how can I use CallFunc.

#12

I tried a cocos new ... and this code and it works for me on iOS and Android.

Have you tried in a cocos new project?

#13

I tried but I still get error.I re-downloaded even the engine but It’s still the same.Can you upload the working class files ?

#14

Its weird, I don’t get these errors. @grimfate do you?

#15

Your code works for me. The error message is a seg fault, which usually means a null (or possibly uninitialised or freed) object is being used. What code are you using @Staletto? Any possibility you are creating objects and not adding them to the scene or retaining them?

#16

I solved it.But can you tell me how can I use RepeatForever with CallFunc ?
