OnCollide weight

[jimmyy1992]

Hi

I want to simulate a blak hole. To do that, i have to do a object1(black hole), that kills an colliding object2. and at the same time the object1 (black hole) must get the mass of the killed object!! how is the script code??
can anybody help? thx

(of course the black hole will have an attraction)

For that you need to store mass somewhere (for example in unused controllerAcc property) and read it onCollide.

For 1sq.m black hole object:

Code: Select all

onCollide = (e) => {density = density + e.other.controllerAcc; e.other.controllerAcc = 0; e.other.Density = 0}

p.s. density=0 works only in algodoo, in Phun you should try airFricionMult = NaN or something like that..

okey..thanks!! is it possible to make a killer?? is it still a collision?

Yes it's possible to add killer geometry but it should be slightly smaller than blackhole one. Killer itself will not generate onCollide event.

it can generate it on immortal objects

sorry i tryed it out. and it didn't work. object1 didn't get the mass of object 2.. all the rest worked fine thanks..
why? thanks

ps: i have algodoo

Try:

Code: Select all

onCollide=(e)+=>{density = (density + e.other.density); e.other.density = 0}

Phun version:

Code: Select all

onCollide=(e)+=>{density = (density + e.other.density); e.other.airFrictionMult - NaN}

And put either in the black hole object.

Jiiha... iit works fine!! Thanks!!

It you want it to be realistic you need to think of something different

okeii.. have you any good suggestion? =)
thanks for your advise

[KarateBrot]

hmm yeah i thought of it a bit but i don't think if it really should be realistic you have to assign a variable for each object that includes it's mass to make it realistic. for example with controlleracc like kilinich said before but if it doesn't work there are still other possibilities to assign mass.
And dependent on the mass of the black hole you could make the radius of it's event horizon geting bigger with "New method". you have to erase the old black hole and at the same position (you need new method to detect it) it spawns a new circle with a bigger radius. i hope it will look like it's getting bigger.
