                  问题描述

                  我想检测一个精灵与另一个精灵的碰撞.但我想检查精灵是否与其他精灵的左侧部分接触或与精灵的右侧部分接触.我正在使用下面的代码来检测碰撞.但这会检测整体碰撞(精灵在其他精灵的任何点接触).但是如果精灵被触摸到其他精灵的正面,则要算作碰撞.

                  i want to detect collision of a sprite with another sprite. but i want to check whether the sprite is touched with left part of other sprite or touched with right part of sprite. i am using below code for detecting collision. but this detect the overall collision(sprite touched to at any point of other sprite). but want to count is as collision if the sprite is touched to front side of other sprite.

                  if (CGRectIntersectsRect(sprite1.boundingBox, sprite2.boundingBox)) {
                              NSLog(@"sprite1 to delete");
                   }
                  

                  有人知道怎么做吗?

                  推荐答案

                  你能比较一下碰撞时精灵的位置吗?

                  Would you be able to compare the positions of the sprites at the time of collision?

                  假设 sprite1.anchorpoint, sprite2.anchorpoint = ccp(0,0).检测到碰撞时:

                  Assume sprite1.anchorpoint, sprite2.anchorpoint = ccp(0,0). At time when collision is detected:

                  // left part of sprite 1 touched right part of sprite 2
                  if (sprite1.position.x == sprite2.position.x + sprite2.contentSize.width.x) {
                  
                  }
                  // right part of sprite 1 touched left part of sprite 2
                  else if (sprite1.position.x + sprite1.contentSize.width.x == sprite2.position.x) {
                  
                  }
