是有可能检测一个碰撞上只有特定颜色？ AS3 [英] Is it possible to detect a collision on only a specific colour? AS3

问题描述

我工作的一个游戏，一个边框围绕一个球绘制。

I am working on a game and a border is drawn around a ball.

边框尺寸取自一个XML文件中。

The border dimensions are taken from an XML file.

边框的边缘都使用由：

    lineThick = Number(xmlContent.rec[i].look.strokethick);

    lineColor = int(xmlContent.rec[i].look.strokehex);

    drawings.graphics.lineStyle(lineThick, lineColor);

    drawings.graphics.beginFill(fillColor);

在一个创建绘图功能

现在我想知道的是如何检测的时候，我的球（即移动在屏幕上）已经打到了边？

Now what I want to know is how can I detect when my ball (that is moving around the screen) has hit the edge?

我想过要把它检测到它撞色黑色，因为这是所有的线的颜色。

I thought about trying to make it detect when it hits the colour black because that is the colour of all the lines.

有没有更好的办法？是否有可能检测出黑色，使球反弹回来？

Is there a better way? is it possible to detect the colour black and make the ball bounce back?

推荐答案

在codeI用于游戏的这一部分，你可能需要稍微改变它自己的需求： 函数testCollisions（）：无效{      对于（VAR我：INT = enemies.length -1; I＆GT; = 0;我 - ）{            tempEnemy =敌人[I]           如果（tempEnemy.hitTestObject（播放器））{           //这是部分放$ C $下反弹回球           }       }     }

This a part of the code i use for gaming, you might have to change it slightly to your own need: function testCollisions():void { for (var i:int = enemies.length -1;i >= 0;i--) { tempEnemy = enemies[i]; if (tempEnemy.hitTestObject(player)) { //this is the part to put the code for bouncing the ball back } } }

下面我测试的球员碰撞的tempEnemy。我把所有的敌人阵列我tempEnemy对象。这可能不是最有效的，但它的工作原理。

Here i am testing collision of player on tempEnemy. i have all of my tempEnemy objects in the enemies array. this might not be the most efficient but it works.
