How to pass each other By PhysicsWorld

[anon36805592]

please tell me.
In the code I wrote, the ball hits in the middle and stops.
I want to make rolling balls pass each other.
Thanks.

auto blueBall = Sprite::create(“s.png”);
blueBall->setPosition(Vec2((visibleSize.width/2 + origin.x) -200, (visibleSize.height/2 + origin.y) +300));
auto blueBallBody = PhysicsBody::createCircle((blueBall->getContentSize().width / 2), PhysicsMaterial(1.0f, 0.0f, 0.5f));
blueBallBody->setDynamic(true);
blueBallBody->setRotationEnable(true);
blueBall->setPhysicsBody(blueBallBody);
addChild(blueBall, 2);

auto redBall = Sprite::create("ss.png");
redBall->setPosition(Vec2((visibleSize.width/2 + origin.x) +200, (visibleSize.height/2 + origin.y) +300));
auto redBallBody = PhysicsBody::createCircle((redBall->getContentSize().width / 2), PhysicsMaterial(1.0f, 0.0f, 0.5f));
redBallBody->setDynamic(true);
redBallBody->setRotationEnable(true);
redBall->setPhysicsBody(redBallBody);
addChild(redBall, 3);

auto InclinationLeft = Sprite::create("sss.png");
InclinationLeft->setAnchorPoint(Vec2::ANCHOR_MIDDLE_RIGHT);
InclinationLeft->setPosition(Vec2((visibleSize.width/2 + origin.x) +0 *deviceScale, (visibleSize.height/2 + origin.y) -550 *deviceScale));
InclinationLeft->setScale(deviceScale);
auto InclinationLeftBody = PhysicsBody::createBox(InclinationLeft->getContentSize(), PhysicsMaterial(1.0f, 0.0f, 1.0f));
InclinationLeftBody->setDynamic(false);
InclinationLeft->setPhysicsBody(InclinationLeftBody);
InclinationLeft->setRotation(20);
this->addChild(InclinationLeft, 1);

auto InclinationRight = Sprite::create("sss.png");
InclinationRight->setAnchorPoint(Vec2::ANCHOR_MIDDLE_LEFT);
InclinationRight->setPosition(Vec2((visibleSize.width/2 + origin.x) +0 *deviceScale, (visibleSize.height/2 + origin.y) -550 *deviceScale));
InclinationRight->setScale(deviceScale);
auto InclinationRightBody = PhysicsBody::createBox(InclinationRight->getContentSize(), PhysicsMaterial(1.0f, 0.0f, 1.0f));
InclinationRightBody->setDynamic(false);
InclinationRight->setPhysicsBody(InclinationRightBody);
InclinationRight->setRotation(-20);
this->addChild(InclinationRight, 1);

Please read this thread…

[SOLVED] Can someone please point out what i did wrong in my code for detecting collision in cocos2dx?

I think people need to understand this to use it properly. Whenever you create any physics body these three must need to be set setCategoryBitmask, setCollisionBitmask, setContactTestBitmask, if any one is missing without initialize then it will not give you desire outout. please dont use 'true', 'false' or '0' '1', it will make you difficult to understand. Also dont set different collision mask for CATEGORY & COLLISION, use single mask per object, like below. #define COL_MASK_BLANK 0x00000…

Thank you. I did it😊

@smitpatel88 You are correct as always, my friend. I was going to reply check bitmasks until I saw your reply

You are correct as always, my friend.

Thanks .
