Hello,

 

I don’t understand why no rotation neither torque is applied. The Entity keep still, only linear impulses make it move. Tryed with applying an angularImpulse later, with applying a force to the top (not the center) and with different values.

Here the simpliest version of my code:

 

import Felgo 3.0
import QtQuick 2.0
import "entities"


GameWindow {
    id: gameWindow
    activeScene: scene
    width: 960
    height: 640

    Scene {
        id: scene

        EntityManager {id:entityManager; entityContainer: scene}

        PhysicsWorld {
            id: world
            updatesPerSecondForPhysics:60
            gravity.y: 1
        }

        width: 480
        height: 320

        Rectangle {
            id: rectangle
            anchors.fill: parent

            Sample {
                x: 200
                y: -150
            }
        }

    }
}

 

 

 

EntityBase {
    id: entity

    Rectangle{
        id: boxImage
        height: 80
        width: 40
    }

    BoxCollider{
        id: boxCollider
        width: boxImage.width
        height: boxImage.height

        rotation: 25
        torque: 200
    }
}

Hi Benoit!

The effect of the torque setting strongly depends on the weight of the body. The density property specifies the weight of a body in kg/pixels^2 and should be set to an appropriate setting.

For example, with these values you should see some effect when applying a torque to the body:

EntityBase {
  id: entity

  Rectangle{
      id: boxImage
      height: 80
      width: 40
  }

  BoxCollider{
      id: boxCollider
      anchors.centerIn: parent
      width: boxImage.width
      height: boxImage.height

      density: 0.001
      torque: 1000
  }
}

Best,
Günther

Thanks it works
