I have iOS exported game project from cocos creator as the game opens in full screen so placing banner ad view as subview of game view makes banner ad overlay on the game canvas.
I want that banner ad appears separately below the game canvas like shown in following game.

Hi,
I was using v3.17 but Apple will not allow contains UIWebKit from April, 2020 for new app. So, I want to start new project with new version. I downloaded v4 from website. I created new project.
cocos new Test -l cpp -p com.Kemal.Test
After, I run cmake command according to docs (https://github.com/cocos2d/cocos2d-x/blob/v4/cmake/README.md#generate-macos-project).
I opened xcodeproj in ios-build folder. I fix bundle identifier and certificate for device running. It built. Here, I don’t have any problem.Later, I created new header file and called “Definitions.h”. I include this file to HelloWorldScene.cpp (#include “Definitions.h”). And, ‘Definitions.h’ file not found. I don’t know that how to work cmake system but I added to list for cross-platforms.
list(APPEND GAME_HEADER
Classes/AppDelegate.h
Classes/HelloWorldScene.h
Definitions.h
)In this time, Xcode build always cancelled. Also, I removed “Definitions.h” from list, but I can’t build. I checked signing and this values is removed. I fixed this values but this values is removed when I rebuild project. On the other hand, I’m trying to build for simulator and still cancelled.
How can I add new file to project?
Thanks.

Hi, there, Happy new year
I’m using cocos js for some time, now i got a problem is that if i create a new gamemodel included a particle effect from a json file, the particle works very well, but if i reuse that object. the particle effect does not work any more, so how do I do to reuse a game model with particle effect? I’m using cocos 3.10 right now, cocos js version I believe is es5

Hi. I am working on learning Cocos2d-x (v3.17.2) by programming the classic artillery game (2 cannons fire shells in hyperbolic arc at given angle and force - simple but covers basics of IO, sprites, etc.).
When my falling sprite’s edge (gravity physics) hits edge I placed on view, program aborts in source ccPhysicsBody.cpp L376:
…
void PhysicsBody::setPosition(float positionX, float positionY)
{
cpVect tt;tt.x = positionX + _positionOffset.x; tt.y = positionY + _positionOffset.y; cpBodySetPosition(_cpBody, tt); // <--ABORT HERE}
…Based on test cpp and internet I have:
- Created scene and a sprite
- Added physic and gravity to scene and sprite - which now convincingly start falling and accelerating.
- Added an edge box to view like test cpp, and edge box to sprite
- Enabled debugging for physics and edges - I see box around sprite and view as expected.
- When sprite hits view edge, the sprite edge box goes a few pixels across view edge, and I get a program abort in void PhysicsBody::setPosition(float positionX, float positionY)
Can anyone offer suggestions to why collision leads to abort in physics code? What I missed / should change?
Note, if I remove the edge from sprite physics body it falls off screen as expected without crash, so I think problem is about physics and edges, not going off-screen.My Code in scene init (some removed for clarity):
…
initWithPhysics();
getPhysicsWorld()->setGravity(Vec2(0, -980));//Create edge around view
auto node = Node::create();
node->addComponent(PhysicsBody::createEdgeBox(VisibleRect::getVisibleRect().size));
node->setPosition(VisibleRect::center());
this->addChild(node);getPhysicsWorld()->setDebugDrawMask(PhysicsWorld::DEBUGDRAW_ALL); //show collision boxes
//add cannon class’ sprite to scene
this->addChild(_cannon1.Sprite(), 2);//add physics to sprite
auto pb = PhysicsBody::create();
pb->addShape(PhysicsShapeEdgeBox::create(_cannon1.Sprite()->getContentSize()));
_cannon1.Sprite()->setPhysicsBody(pb); //need edge or cannon falls through ground - if not here no crash//place in center to fall
_cannon1.Sprite()->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y));this->scheduleUpdate();
return true;

I want to check my physicsbody sprite is resting or not but I want it with best approach to performance reason.
Instead manually checking sprite isResting, sprite should emit resting event.
Does sprites can emit events?

I am using TableView in two different areas in my app. The behaviour is strangely different while I think the code is similar. The desired behaviour is as in the video below. When I pull down it snaps back to the top. When I pull up, the cells are truncated at the top and it snaps back. The cells do not go pass the top. The code for this follows:
pagesTableView = TableView::create(this, Size(panelWidth, contentHeight));
pagesTableView->setAnchorPoint(Vec2::ANCHOR_BOTTOM_LEFT);
pagesTableView->setPosition(Vec2(xp,yp));
pagesTableView->setVerticalFillOrder(TableView::VerticalFillOrder::TOP_DOWN);
pagesTableView->setDelegate(this);The next table view does not clip off the top. The cells go pass the top position, and do not snap back.
itemsTableView = TableView::create(this, Size(contentWidth, contentHeight));
itemsTableView->setAnchorPoint(Vec2::ANCHOR_BOTTOM_LEFT);
itemsTableView->setPosition(Vec2(xLeft, yBottom));
itemsTableView->setVerticalFillOrder(TableView::VerticalFillOrder::TOP_DOWN);
itemsTableView->setDelegate(this);I am not sure what I’m missing. Perhaps there is some undetermined default that I am not setting.
Any help appreciated. Thank you.

Suppose I have sprite and i set its position randomly, how can determine sprite is visible on screen or not and if visible get relative location on screen.
I am asking this to make mario style follow.
Follower shouldn’t follow sprite when its on screen center-200 between screen center+200I tried Follow::createWithOffset looks like doesnt work intended or I missing something.
for example
Follow::createWithOffset(sprite3, 200, 0, Rect(0,-3200, 4000, 800));this works intended follows sprite at xOffset 200, if I only move player right to left its still follow player at same xOffset 200 point.
any suggestion about usage of createWithOffset?

Hello!
I’m still a bit confused on how to reuse a clip on AudioEngine library, but it is not necessary for my game to use it, so i can switch back to SimpleAudioEngine…
I have downloaded v4.0 since i will work for iOS too…
Will you deprecate the SimpleAudioEngine library in the future?.. can i use it securely?.Thanks!

Hi,
I’am facing a issue in taking new iOS build in Cocos2d-x-4.0, where i’am using CMake(3.16.2) also.
Xcode(10.1) is the code editor.Usually we used to take debug build in the Xcode interface itself, now am not even getting list of simulators when I started to use Cocos2d-x-4.0
Please do come up solutions, So thanks in ADVANCE.
