[英]How can I prevent two types of SpriteKit nodes from colliding with each other?
I'm writing a small game using Apple Sprite Kit. 我正在使用Apple Sprite Kit编写一款小游戏。
I'm having trouble with the collisions. 我遇到了碰撞问题。 Sometimes I dont want two skSpriteNodes with physicsBodys to interact. 有时我不想让两个带有physicsBodys的skSpriteNodes进行交互。
as an example I have the HERO , ENEMYS and SHOTS and I want the SHOTS only to interact with the ENEMYS. 作为一个例子,我有HERO,ENEMYS和SHOTS,我希望SHOTS只与ENEMYS交互。
But when 2 shots collide together then they change their position.! 但是当两个镜头碰撞在一起时,它们会改变它们的位置。
the code for the shot is 镜头的代码是
shot.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:shot.size];
shot.physicsBody.dynamic = YES;
shot.physicsBody.allowsRotation = FALSE;
shot.physicsBody.categoryBitMask = playerShotCategory;
shot.physicsBody.contactTestBitMask = enemyCategory;
and the code for the enemy is 并且敌人的代码是
activeGameObject.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:activeGameObject.size];
activeGameObject.physicsBody.dynamic = YES;
activeGameObject.physicsBody.categoryBitMask = enemyCategory;
activeGameObject.physicsBody.contactTestBitMask = playerCategory | playerShotCategory;
activeGameObject.physicsBody.allowsRotation = FALSE;
If you only want shots to interact with enemies, you'll need to add this code: 如果你只想让镜头与敌人交互,你需要添加以下代码:
shot.physicsBody.collisionBitMask = enemyCategory;
activeGameObject.physicsBody.collisionBitMask = playerShotCategory|playerCategory;
See the documentation for collisionBitMask for more information. 有关更多信息,请参阅collisionBitMask的文档 。 You may need to tinker with the collisionBitMask if you have other categories that you want involved in the collisions. 如果您想要在碰撞中涉及其他类别,则可能需要修改collisionBitMask。
