    Hi,

     

    I am making a basic shooter game where I need to create bullet on mouse click and shoot it. To create the bullets during runtime I’m using

    entityManager.createEntityFromUrlWithProperties()

     

    But when I trigger the rotation and linear impulse (tried with onBeginContact and a function in the entity) nothing happens. When I use the same code on an entity already loaded on the scene it works just fine, but not on the entity created at runtime. Is this a bug or am I doing something wrong here?

    boxCollider.body.rotation = 90;
    entity.rotation = 90;
    var localForwardVector = boxCollider.body.getWorldVector(Qt.point(1500,0));
    boxCollider.body.applyLinearImpulse(localForwardVector, boxCollider.body.getWorldCenter());

    HI,

    did you have a look at the source code of the CarChallenge demo game, in the Demo folder of the V-PlaySDK?

    There we are doing something similar. Are you maybe applying the impulse before the component is loaded completely? In our demo we apply the impulse like this:

    // this code is part of Rocket.qml
    Component.onCompleted: {
      applyForwardImpulse();
    }
    
    function applyForwardImpulse() {
      var localForward = boxCollider.body.getWorldVector(Qt.point(1500,0));
      boxCollider.body.applyLinearImpulse(localForward, boxCollider.body.getWorldCenter());
    }

    Can you maybe post some more code so i can try to recreate your problem?

    Cheers,
    Alex
