问题描述
伙计们，所以我用这段代码创建了一个迷宫，我想对墙进行击打测试，但是当我尝试按if(mc.hitTestObject(tile))进行操作时，它什么也没做.我不确定为什么，这是代码:
Hey guys so I created a maze with this code and I want to hitTest the walls but when i try something along the lines of if (mc.hitTestObject(tile)) it doesn't do anything. And I'm not sure why, here's the code :
package
{
import flash.display.MovieClip;
import flash.events.KeyboardEvent;
import flash.events.Event;
import flash.display.DisplayObject;
public class Main extends MovieClip
{
private var mc:hero = new hero;
private var tile:tile1 = new tile1;
private var mcSpeed:uint = 5;
private var lab1Array:Array = new Array;
private const TILE_WIDTH:uint = 25;
private const TILE_HEIGHT:uint = 25;
private const STAGE_WIDTH:uint = 550;
private const STAGE_HEIGHT:uint = 400;
private var horizontalBlocks = STAGE_WIDTH / TILE_WIDTH;
private var verticalBlocks = STAGE_HEIGHT / TILE_HEIGHT;
private var hitBlock:DisplayObject;
private var leftDown: Boolean = false;
private var rightDown: Boolean = false;
private var botDown: Boolean = false;
private var upDown: Boolean = false;
public function Main()
{
mc.x = 160;
mc.y = 385;
addChild(mc);
for (var i:uint = 0 ; i < verticalBlocks ; i++)
{
lab1Array[i] = new Array;
for (var j:uint=0; j < horizontalBlocks; j++)
{
lab1Array[i].push(0);
}
}
lab1Array = [
[1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],
[1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1],

stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeysDown);
stage.addEventListener(KeyboardEvent.KEY_UP, checkKeysUp);

}
function checkKeysDown (event:KeyboardEvent):void
{
if (event.keyCode == 37 || event.keyCode == 65)
{

}
if (event.keyCode == 38 || event.keyCode == 87)

}

}

}
if (rightDown)
{
mc.x += mcSpeed;
}
if (upDown)
{
mc.y -= mcSpeed;
}
if (botDown)
{
mc.y += mcSpeed;
}
}
function createLab():void
{
for (var i = 0; i < lab1Array.length ; i++)
{
for (var j = 0; j < lab1Array[i].length ; j++)
{
if (lab1Array[i][j] == 1)
{
tile= new tile1;
tile.x = TILE_WIDTH*(j+0.5);
tile.y = TILE_HEIGHT*(i+0.5);
addChild(tile);
}
}
}
}
}
}
推荐答案
您可以使用图块对播放器进行测试 这是通过使用tile类中的更新功能而不是当前使用的更新功能来完成的.这样就完成了 mc.hittestobject(this);
You could use the tile to hit test for the player This is done by using an update function in the tile class, instead of the one you are currently using. This is done like so mc.hittestobject(this);
