How do I Create a throwing sytem?

Hey,

I'm having a hard time figuring out how to create a system where my main character grabs an object, aims and then throws said object.

Ideally an arc would appear on screen showing the trajectory.

Thanks in advance for any help!

The bullet behavior with gravity should be sufficient.

Showing the trajectory is more complicated. You can use the drawing canvas to draw it out, or perhaps make a dotted line with sprites at set intervals.
