I want to turn gravity off for specific entity w/o manipulating with the mass because of colliding of entities

How to do this?

thanks

Hi vladest,

we will add a new property “gravityScale” to our colliders to target exactly this behavior. It will be available within the next daily build for pro-customers.

 

A possible workaround, could be applying a linear impulse with the same force but in the opposite direction of the gravity. This must be done in the same rate as the update rate of the PhysicsWorld, possibly with a Timer with a matching interval. Though I’m not sure if you can achieve perfect results this way.

An example of applying a linear impulse can be found here, right at the bottom of the code:

And another approach:

BoxCollider {    
  ...
  body.force: Qt.point(0,1.002)
}

Worked for me with a gravity.y of 1.

The force property is applied every update, just like we need. I needed to play around a little bit with the exact value as you can see (1.002), but you could achieve quite good results this way, if you don’t want to wait for our daily build.

 

Cheers

Will try this

Thanks!
