Cocos2d 3.0 + Chipmunk + CCAnimation：将animation物体移动到物体上。 怎么样？

我有一艘附有物理机构的船。 这艘船是静态的物理机构。 船从CCAnimateMoveTo移动从左到右。 当我点击屏幕时，我的angular色掉下来了。 我发现碰撞很好。 但是我想在碰撞后我的angular色就​​会落在船上，并继续前进。 人物是dynamic的身体。 链接到示例video： 示例video

我在这里创造一条船：

- (void)createBoat { currentBoat = [CCSprite spriteWithImageNamed:@"Boat.png"]; currentBoat.position = ccp(0 - currentBoat.boundingBox.size.width, winSize.height * 0.2); // currentBoat.physicsBody = [CCPhysicsBody bodyWithRect:(CGRect){0, 0, currentBoat.contentSize.width, currentBoat.contentSize.height * 0.5} cornerRadius:0]; CGPoint shape[6]; shape[0] = ccp(0, 30); shape[1] = ccp(64, 10); shape[2] = ccp(128, 30); shape[3] = ccp(128, 0); shape[4] = ccp(0, 0); shape[5] = ccp(0, 30); currentBoat.physicsBody = [CCPhysicsBody bodyWithPolylineFromPoints:shape count:6 cornerRadius:0 looped:NO]; currentBoat.physicsBody.type = CCPhysicsBodyTypeStatic; currentBoat.physicsBody.collisionGroup = @"BoatGroup"; currentBoat.physicsBody.collisionType = @"BoatCollision"; [physicsWorld addChild:currentBoat z:PHYSICS_Z+3]; id actionMoveBoat = [[CCActionMoveTo alloc] initWithDuration:5.0f position:ccp(winSize.width + currentBoat.boundingBox.size.width, currentBoat.position.y)]; id actionMethod = [CCActionCallFunc actionWithTarget:self selector:@selector(createBoat)]; [currentBoat runAction:[CCActionSequence actions:actionMoveBoat, [[CCActionRemove alloc] init], actionMethod, nil]]; } 

angular色创作：

 - (void)createCharacter { if (needCharacter) { CCSprite *newCharacter = [CCSprite spriteWithImageNamed:@"Character.png"]; newCharacter.opacity = 0; newCharacter.position = ccp(winSize.width * 0.5, winSize.height * 0.76); newCharacter.physicsBody = [CCPhysicsBody bodyWithRect:(CGRect){CGPointZero, newCharacter.contentSize} cornerRadius:0]; newCharacter.physicsBody.affectedByGravity = NO; newCharacter.physicsBody.allowsRotation = YES; newCharacter.physicsBody.collisionGroup = @"playerGroup"; newCharacter.physicsBody.collisionType = @"playerCollision"; [physicsWorld addChild:newCharacter z:PHYSICS_Z+4]; id actionFadeIn = [[CCActionFadeIn alloc] initWithDuration:0.5]; [newCharacter runAction:actionFadeIn]; [allCharacters addObject:newCharacter]; needCharacter = false; touchDone = false; } } 

然后检测触摸和碰撞：

 - (void)touchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CCNode *lastCharacter = [allCharacters lastObject]; if (!touchDone) { [lastCharacter.physicsBody applyImpulse:ccp(0, 300)]; lastCharacter.physicsBody.type = CCPhysicsBodyTypeDynamic; lastCharacter.physicsBody.affectedByGravity = YES; touchDone = true; } } - (BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair playerCollision:(CCNode *)currentCharacterC BoatCollision:(CCNode *)currentBoatC { currentCharacterC.physicsBody.collisionType = @"tmpCollision"; CCLOG(@"score++"); if ([allCharacters containsObject:currentCharacterC]) { score++; [scores setString:[NSString stringWithFormat:@"%d", score]]; [allCharacters removeAllObjects]; if (lives != 0) { needCharacter = true; [self createCharacter]; } } CCLOG(@"allCharacters = %@", allCharacters); return YES; } 

Answer 1

以及我也面临同样的问题，试图增加摩擦/表面速度等，它并没有真正的工作。 最后必须以我自己的方式来解决它，每当玩家登陆任何一个身体时，你都会保持一个指向该玩家对象_bodyUnderFeet的指针。 现在，在更新循环中，将_bodyUnderFeet的速度添加到玩家计算的速度。 请参阅zeroVel_x的使用

示例代码在这里：

 void Player::update(float dt) { float zeroVel_x = 0; if(_bodyUnderFeet != NULL) { zeroVel_x = _bodyUnderFeet->vx; } cpBody *bd = getCPBody(); assert(bd); //log("Body angle %f", bd->a); //check forward backward or at rest float accel = _accelGround; if(_onGroundBoost < UP_BOOST) { accel = _accelAir; } if(_touchPressedB) { if(!isFlippedX()) { setFlippedX(true); } //cpBodySetVel(bd, cpv(cpBodyGetVel(bd).x - accel*0.25, 0)); cpVect bdv = cpBodyGetVel(bd); bdv.x = bdv.x - zeroVel_x; if(bdv.x > 0) bdv.x = 0; if(bdv.x > -_maxVelocity.x) cpBodySetVel(bd, cpv(zeroVel_x + bdv.x - accel*0.25, bdv.y)); } else if(_touchPressedF) { if(isFlippedX()) { setFlippedX(false); } //cpBodySetVel(bd, cpv(cpBodyGetVel(bd).x + accel*0.25, 0)); cpVect bdv = cpBodyGetVel(bd); bdv.x = bdv.x - zeroVel_x; if(bdv.x < 0) bdv.x = 0; if(bdv.x < _maxVelocity.x) cpBodySetVel(bd, cpv(zeroVel_x+bdv.x + accel*0.25, bdv.y)); } else { cpFloat bd_x = cpBodyGetVel(bd).x; bd_x = bd_x - zeroVel_x; if(bd_x>0) { if(bd_x > accel*0.25) { cpBodySetVel(bd, cpv(zeroVel_x+bd_x - accel*0.25, cpBodyGetVel(bd).y)); } else { cpBodySetVel(bd, cpv(zeroVel_x+0, cpBodyGetVel(bd).y)); } } else if(bd_x < 0) { if(bd_x < accel*0.25) { cpBodySetVel(bd, cpv(zeroVel_x+bd_x + accel*0.25, cpBodyGetVel(bd).y)); } else { cpBodySetVel(bd, cpv(zeroVel_x+0, cpBodyGetVel(bd).y)); } } } //check jump if(_touchPressedJ) { if(_onGroundBoost) { cpVect bdv = cpBodyGetVel(bd); if(bdv.y < 0) bdv.y = 0; if((bdv.y + _accelUp) < _maxVelocity.y) { cpBodySetVel(bd, cpv(bdv.x, bdv.y + _accelUp)); --_onGroundBoost; } else { cpBodySetVel(bd, cpv(bdv.x, _maxVelocity.y)); _onGroundBoost = 0; } } } //check shots if(_touchPressedS) { if(!_bulletFired) { } } //check home if(_touchPressedH) { } boundRotation(bd); }

我想，你可以在倒下之后增加人与船之间的摩擦。 并减less弹性。 那么船就可以把这个男人带走

只是一个伎俩。
