applyForce on kinematic object ...

Getting Started Newbie Questions
#1

I tried various applyForce, applyLinearImpulse on object with no success when set to “kinematic” object.
Things begin to move when I set to “dynamic” (with setGravity to 0,0).

physics.addBody( ball, "dynamic", { density = 1, friction = 0.3 } ) ball:applyLinearImpulse( math.random(-20,20), math.random(-20,20), ball.x, ball.y) … and the ball moves

physics.addBody( ball, "kinematic", { density = 1, friction = 0.3 } ) ball:applyLinearImpulse( math.random(-20,20), math.random(-20,20), ball.x, ball.y) … and the ball doesn’t move

I thought kinematic object were subjects to forces … [import]uid: 9328 topic_id: 4784 reply_id: 304784[/import]

BTW, is there a way to set an “attraction point” on the screen ? A kind of setGravityPoint feature ?

Did you ever figure this out? I’m having the same problem. [import]uid: 52127 topic_id: 4784 reply_id: 38839[/import]

You mean “attraction point” : no.
