Question

抱歉重新打开这个标题，但这个问题的标题都没有给我带来太多帮助。在我的游戏中你是一艘太空飞船，你试图逃离传入的小行星。当你的船接触到一颗小行星时，你就会爆炸。我的代码就像这些;

static const uint32_t asteroidCategory = 1;
static const uint32_t playerCategory = 2;
static const uint32_t laserCategory = 3;

player.physicsBody.categoryBitMask = playerCategory;
player.physicsBody.contactTestBitMask = asteroidCategory;
player.physicsBody.collisionBitMask = 0; 

asteroid.physicsBody.categoryBitMask=asteroidCategory;
asteroid.physicsBody.contactTestBitMask=playerCategory;
asteroid.physicsBody.collisionBitMask=0;

但我不知道我应该在'didBeginContact'方法做什么。请帮帮我，谢谢...

尝试从

开始

-(void)didBeginContact:(SKPhysicsContact *)contact
{
SKPhysicsBody *firstBody, *secondBody;

if (contact.bodyA.categoryBitMask < contact.bodyB.categoryBitMask)
{
    firstBody = contact.bodyA;
    secondBody = contact.bodyB;
}
else
{
    firstBody = contact.bodyB;
    secondBody = contact.bodyA;
}
if ((firstBody.categoryBitMask & playerCategory) != 0 &&
    (secondBody.categoryBitMask & astroidCategory) != 0)
{
    [self player:(SKSpriteNode *) firstBody.node didCollideWithAstroid:(SKSpriteNode *) secondBody.node];
}

你还需要为'didCollideWithAstroid'

制作一个方法
