Physic mode with a cannon attached to a ship that moves

[Daniel Pers]

How can a cannonball be thrown into physic mode by a pirate cannon attached to a ship that moves?

Hi Daniel, 

You can try the coding that I have included. This seems to work quite well, but is also quite basic, so I'm sure you could improve on it. 

You need to attach a "muzzle" to the end of the cannon and reduce its opacity to zero, this basically works as a loading area. Then group a "target" to the pirate ship and place it in the position that you would like the cannon ball to shoot. 

This is the space I quickly built so you can see how it works.

you'll also need to unparent / unattach the cannonball and put it somewhere in the scene where it’s not seen :)

Thank you Ben for your help, but I can not keep the cannonball in a loading area.

Hey Daniel, 

The physical ball, the first object that just rolls away can be hidden somewhere - either in the scene or by setting its physical position underground at start of scene. 

Then the coding should work fine and the cannonballs will appear/fire when the action is clicked. 

I hope this helps. 

Thanks
