how to trow a object to a image point?

The mouse isn't setting the angle, it's setting the target (or the location to arc to).

To target a different object just replace "mousex" and "mousey" with the object's x and y.

This worked with your newest example, but for some reason it won't respond in the physics example you posted.

It works with the latest if you also get lucid's physics fix (in the same thread) and uncheck and check "Use old units".

You can also do it with just events:

That's it, I didn't uncheck the Use old units box. I used the ball behavior eventually, but it could be useful somewhere else and I can see what I've made wrong when I tried to made it myself, thanks for the example.

Could fake the throw arc with cosine or cubic interpolation?
