How to make a coin actor toss and spin to drop on the floor?

I'm trying to make my enemy spawn a coin upon killed and then it will toss, bounce just like in real life.

However, when I use the 'rotate' behaviour my coin will always fly out of the screen.

I didn't set any gravity.

Can somebody explain to me why is it like this?

    Set the rotation to relative to scene rather than relative to actor.

    Post a screenshot of your rules and maybe we can spot something that isn't right.

    I thought 'Rotate' could help me create a coin tossing effect, turn out my understanding of the behaviour is wrong. It is use to make the actor move in a circular direction in the scene and not "Rotate" it at it's origin.

    Rotate rotates the coin about its origin, the reason it is moving in a circular path is that you have another rules (a rule you are not showing us) that is also effecting the coin's movement.

    It's likely you have a Move/Move To/Accelerate behaviour with the 'Relative To:' part set to 'Actor' ?

    Like @tatiang says, if you post your rules then someone might be able to help you out, without at least a screenshot of the rules controlling the coin it'll just be a long and dreary guessing game. Lol :smiley:

    Alright, I got a bit lazy preparing the screenshot but here it is.

    Yes Socks, I removed the other movement behaviour and 'Rotate' indeed rotates actor in it's origin. And I do have 'Accelerate' and increase velocity behaviour to create the jump and fall effect.

    The moment when I add in 'Rotate' it will just fly outside the screen.

    IT'S WORKING!!!

    Thank you Socks and Tatiang.

    You could also just use an animation instead of wasting processing power on physics for an actor that really doesn't need physics.
