Android 使用AndEngine和Box2D制作英雄跳跃
我不熟悉汽车和发动机。目前我想让我的游戏英雄跳跃使用安引擎和Box2D。我已经尝试了很多方法来做到这一点。但是没有成功 下面是我的代码,让角色在触摸屏幕上显示的左右箭头时左右行走。现在我想让它跳上润色箭头。 这是我的密码Android 使用AndEngine和Box2D制作英雄跳跃,android,box2d,andengine,Android,Box2d,Andengine,我不熟悉汽车和发动机。目前我想让我的游戏英雄跳跃使用安引擎和Box2D。我已经尝试了很多方法来做到这一点。但是没有成功 下面是我的代码,让角色在触摸屏幕上显示的左右箭头时左右行走。现在我想让它跳上润色箭头。 这是我的密码 public jump(int pLayerCount, final BaseGameActivity game) { super(pLayerCount); this.game=game; gravity=new Vector2(0,SensorMa

特别是看看安德林的样品 从本质上讲,要跳跃,需要设置物理体的线速度
Vector2 velocity = new Vector2(0, -50); //experiment with the numbers!!
body.setLinearVelocity(velocity);
Animatedsprite yas = new Animatedsprite(XPosition,YPosition, (ITiledTextureRegion) this.yourspriteregion, this.getVertexBufferObjectManager());
Body yasbody;
this.physicsworld.registerPhysicsConnector(new PhysicsConnector(yas, yasbody, true, true));
yasbody.setLinearVelocity(velocity);

运动员跳跃:
playerBody.setLinearVelocity(new Vector2(playerBody.getLinearVelocity().x+1,-10f));
playerBody.setLinearVelocity(new Vector2(2,playerBody.getLinearVelocity().y));
玩家移动:
playerBody.setLinearVelocity((int)5, 400);

首先创建精灵,然后将其添加到物理体中
Vector2 velocity = new Vector2(0, -50); //experiment with the numbers!!
body.setLinearVelocity(velocity);

您需要为正确跳跃设置实际速度x。 例如:
playerBody.setLinearVelocity(new Vector2(playerBody.getLinearVelocity().x,-jump_speed));

我已经试过了,但角色并没有停止接触,而是继续跳跃。所以有没有办法让它停止接触地面。一点也不停止?还是经常反弹?如果是后者,请使用“恢复”设置以降低碰撞的弹性。还有人会说,你应该使用线性脉冲而不是速度,因为它更符合真实世界的物理,但速度会起作用。我尝试过这个方法,但角色不会停止触碰,而是继续跳跃。那么有没有办法让它停止触碰地面。一点也不停止?还是经常反弹?如果是后者,请使用“恢复”设置以降低碰撞的弹性。也有人会说,你应该应用线性脉冲而不是速度,因为这更符合真实世界的物理,但速度会起作用。
