Oncollide delete now more possible?

[Ian151]

I read the algodoo changelog (that I have now) and noticed something like this...
"fixed bug - objects without positive density shouldn't crash the application"

are you thinking what I'm thinking? Maybe it's better to script an object to erase on command much better now?

technically, 0 isnt negative OR positive. instead of using 0, use use NaN

I don't see what density has to do with anything.

EDIT: Wow, we just posted at the same time.

I don't see what density has to do with anything.

velocity = gravity / density (or something)

if density is equal to 0, youre dividing by 0

phun goes boom

as long as it isnt moving when its changed to 0, its fine. if it moves, it crashes. however, if you set it to NaN, you can have it move without crashing, and it still deletes

volume = mass / density

but because phun /algodoo only has got 2 dimensions it is area = mass / density

[Chronos]

i knew it was something like that. but still, if density = 0, mass = 0, so youre still dividing by zero, so phun still crashes

[KarateBrot]

yeah i guessed that too in the phun forum

[Rhett97]

Well i can see how it can crash phun...It probably cant handle a paradox.... its basically a paradox

[Ivanlul]

Oh, now I know why it worked in my scene.

[fox11trot]

i always set the density to like .00000000000000000001 and didnt change the collideset so basically the object on collide floats up so fast it doesnt hit anything except the plane that deletes things

You are correct. Changing density to 0 works in Algodoo it was one of the annoying bugs that emil was able to fix. Have fun deleting things!

velocity = gravity / density

Combot, you idiot.

Whoa! Well ok that sounds good then, I thought I even saw you say it wasn't before but I guess you changed your mind because you found out about that bug before. ok!

I would suggest using density = 0, because if something is fixated to it, it won't be deleted (if you use density = NaN, anything fixated to it disappears too).
