Box2D Forums

I am using a kinematic body for my moving platform on x-axis, so I set the linear velocity to b2vec2(5,0).

When the player jump on the platform, it works like it is suppose to. But the thing is that my platform is on the obstacle layer and I am moving it with the parallax layer.

So if I setTransform the kinematic platform to follow the obstacle layer than it's physics will not work and the player will slip-off the platform.

I'm developing for iOS and using cocos2d api. Anyway around this?

Calculate the layer offset difference then minus it from the velocity and apply it to the setLinearVelocity rather than the setTransform method. Cheers.
