朝一个方向移动 cocos2d-iphone+box2d 男孩
请有人就此给我建议。
我有一个 cocos2d-iphone +box2d 主体，我希望仅使用加速计控件和视差滚动在一个方向上移动（仅从 iphone 屏幕的左到右移动）。请问我该怎么做，因为一旦设备倾斜，身体就会向左和向右移动。我不想使用力量或冲动，因为我将不会启用触摸控制。 这是我的加速度计代码：
- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration
*)acceleration {
float32 accelerationFraction = acceleration.y * 6;
if (accelerationFraction < -1) {
accelerationFraction = -1;
} else if (accelerationFraction > 1) {
accelerationFraction = 1;
b2Vec2 gravity(-acceleration.y *10, acceleration.x *10);
world->SetGravity( gravity );
}
提前感谢您的帮助。
Please can someone advice me on this.
I have a cocos2d-iphone +box2d body I wish to move only in one direction(movement only from left to right of the iphone screen) using only the accelerometer controls and parallax scrolling. Please how do I do this as at the moment the body moves both to the left and right once the device is tilted. I do not want to use forces or impulse since I will NOT be enabling touch controls.
This is my accelerometer code :
- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration
*)acceleration {
float32 accelerationFraction = acceleration.y * 6;
if (accelerationFraction < -1) {
accelerationFraction = -1;
} else if (accelerationFraction > 1) {
accelerationFraction = 1;
b2Vec2 gravity(-acceleration.y *10, acceleration.x *10);
world->SetGravity( gravity );
}
Thanks in advance for your help .

您应该使用 mouseJoints。看看这个 教程。在那里他准确地解释了你想要实现的目标。
