Is slicing possible?

Hello everyone,

Just got a quick question, is slicing possible? Because its able in box2d.

By slicing, do you mean cutting an actor in half with a gesture with a finger, like fruit ninja or cut the rope?

If so, I think this is possible. Try:
Always
Create actor "Blade segment" at x of touch, y of touch.

And a behavior for the Blade segment actor:
When created
Do After .2 seconds
Kill Self

Finally, a behavior for the actor to be sliced:
When this collides with something else
Switch animation to sliced
[do other things you want the actor to do when sliced] .

Hello PrunePlum,

Thanks for the tips I will take a look at it tommorow.

@PrunePlum games, that will only change the actor's animation to a "sliced" version, which isn't very versatile. I think what he means would be what Fruit Ninja actually features, which is dynamic slicing which creates two separate entities.

There's probably something being done with the Box2D collision shapes where two new shapes are made using the existing shape and the intersection of the line. I'd suggest checking around online (maybe on Box2D forums?) to see what other people have suggested doing - I've no doubt that other people have asked the same question there and the style of game is popular.

Here is a nice example/tutorial, but it requires a lot of code of course:
