Question

我正在制作简单的Flash游戏。想法：当点击空格按钮字符必须跳跃时，通过单击（左/右箭头）在地面上行走的绿色角色。现在角色留在地上，走路，但没有与墙壁碰撞（穿过墙壁）。在这部分代码中，我试图与ground3墙碰撞，但它不起作用，角色穿过墙壁，如果我跳到地面3（停留在顶部）我无法向右移动，因为它触及地面3 。我需要做的是，如果角色与墙右侧接触，则将速度设置为0。

以下是代码的一部分（向右移动）：

 if(right){

            Hero.x_speed = walkspeed;
            setDirection(0);
            trace("right");

/////////////////////SOMETHING WRONG HERE//////////////////////////////
            if (ground3.hitTestPoint((centrasXright), centrasY, true)){
                trace("HIT THE WALL/GROUND with RIGHT"); //always get this message when stay on the ground 3
                Hero.x_speed = 0;
            }
            else {
                trace("Do not touch anything");

            }

以下是我的变数：

private var gravity:Number = 0.01;
private const max_speed:int = 8;

private const walkspeed:int = 4;
private const jumpspeed:int = 10;

private const start_x:int = 50;
private const start_y:int = 300;

private var left:Boolean;
private var up:Boolean;
private var right:Boolean;
private var space:Boolean;

private var ground:Ground = new Ground;
private var Hero:hero = new hero;

以下是我的代码的一部分：

private function create_hero(){
            addChild(Hero);
            Hero.x = start_x;
            Hero.y = ground.y-30;
            Hero.x_speed = 0;
            Hero.y_speed = 0;


        }
        private function setDirection(param) {
    if (param == 0) {
        Hero.scaleX = 1;
    } else {
        Hero.scaleX = -1;
    }
}

        private function update_hero(){
            Hero.y_speed += gravity;

            if(left){
                Hero.x_speed = -walkspeed;
                setDirection(1);
            }
                var test:MovieClip = new MovieClip;
                test.x = Hero.x;
                test.y = Hero.y;
                var centrasXright:Number = test.x + (Hero.width/2);
                var centrasXleft:Number = test.x - (Hero.width/2);
                var centrasY:Number = test.y + (Hero.height/2);
            if(right){

                Hero.x_speed = walkspeed;
                setDirection(0);
                trace("right");

                if (ground3.hitTestPoint((centrasXright), centrasY, true)){
                    trace("HIT THE WALL/GROUND with RIGHT");
                    Hero.x_speed = 0;
                }
                else {
                    trace("Do not touch anything");

                }


            }
            if(up && Hero_col.can_jump){
                Hero.y_speed = -jumpspeed;


            }

            if(Hero.y_speed > max_speed){
                Hero.y_speed = max_speed;
            }
            ///////////////////////////////////////////////////////////////////
            ////////////////HERE IS COLLISION WITH THE TOP OF GROUND///////////
                        ///////////////////////////////////////////////////////////////////
            if(Hero.y_speed>0 && Hero.hitTestObject(ground) || Hero.hitTestObject(ground3) ){
                        Hero.y_speed=0;

                if(space){
                trace("Clicked SPACE");
                Hero.y_speed += gravity;
                Hero.y -= 80;
                }
                else {

                }


 }

            forecast_y = Hero.y + Hero.y_speed;
            forecast_x = Hero.x + Hero.x_speed;

            Hero_col.solve_all(forecast_x, forecast_y);


            Hero.x_speed = 0;
        }

动作脚本3.使角色正确跳跃并添加与对象的碰撞
