Algodoo

could you explain how you did the scripting so that i could try? and very nice 10/10

Projectile is simple spawned ball.
It has oncollide that do as follows:
-destroy itself (density=0)
-spawn exposion circle (1m radius opaque high refractive index circle)
-spawn laserpen on that circle that's off centered. (like pos:=e.pos+[0.3,0.3])
The explosion circle has onlaserhit that decreases it's density until it reaches 0 and vanishes.
Shortly before disappearing it makes attraction shockwave (density<0.1? {attraction:=(-1000)}:{})
Right combination of spawned circel refractive index, attraction and laserpen light velocity creates flash.

thanks

1st scene from you thats not possible to play. The robots hinges are fixed at the house.

Theese errors has occured since I´ve updated Algodoo to the latest version

That's the reason I stay on earlier version until problems will get fixed and more people get new verision.
It's possible that re-downloading the scene will fix that since it appears that algobox has some problems recently, but I'm not sure.

you can fix that my reloading the scean acouple times, each time the hinges and fixate get a litter closer to where they should be...

Do what 9373 said, for users of the new algodoo, download the scene.
Press play, it will probably mess up then you have to hit rewind until it unloads the scene then you have to forward wind to reload it it will then work

at first I was like with this scean then I realized that by pressing 1 it will unfolled now i'm like

I may be starting to repeat myself, but where does your awesomeness ever end?!? seriously!
10/10 so much fun!
