Explosion with physics ?

[SergioAndre]

Hi all!

I'm trying to make an explosion and when it explodes, all nearby objects move.

I have something done and it works great, but is not very efficient because I use loops and I think it is not the best way ("As many know, the loops are the nemesis of the android exporter"). Apart from this, it is not the cleanest way to do.

Example: https://dl.dropboxusercontent.com/u/...omb%20test.mfa

What I do in the example is that when the bomb explodes, particles are created (with physics) in all directions and when they collide with the boxes, make them move.




Maybe someone knows a better way to do it.


I appreciate any help.

Maybe this example on the clickstore can do the job?

Edit: by the way, I noticed it uses fastloop as well. It is however a very good example, so I'll keep the post.

Faber, does the example in the click store use the built in physics or Box2D extension? BTW SergioAndre, your example is really good. Very well done.

@Klik-iT: it uses built in physics in Fusion. Actually it is not very clear and I had your same doubt.

KLiK-iT, I think the example in click store uses Box2D, as I read in the article.

I am modifying and optimizing my example right now, it's working great but I'm finishing to fix a problem with rotations... in a while I upload it.

Hello SergioAndre,

in Clickstore, i m William Yvart ,it's my physic examples..and I do not use Box2d,only the physic engine of Fusion 2.5 with actif static only..(I change the descriptions examples)

you can see my examples here, some of whom are on the clicktsore:

Okay William, good to know!


I've finished editing my example, I've done it in a simple way. It's not perfect but I think it's fine.

Tell me guys, what do you think about this example?

I think it's very good. The previous one for some reason didn't work when exported as html5, this last one instead works flawlessly (just a little bit slower than the exe version).

Thanks William for clearing that up. Box2D is very good,.but the built in Physics are also good and easier to use. I'm going to download it soon.

SergioAndre, your example is really good. Thanks for posting it. By adjusting the explosion size down to 40x40 or even less,.you can get different effects. Like it will only destroy one TNT box, instead of them all or close to all of them. All in all,.nice example.
